Weight Loss

Back Clinic Weight Loss. People who are overweight or obese and are suffering from back pain may not realize that their excess weight contributes to their back pain. It is a known fact that overweight people are at risk for back pain, joint pain, and muscle strain. Not only is back pain an issue, but other symptoms of obese or overweight people may include fatigue, difficulty breathing, and/or shortness of breath during short periods of physical activity. When this happens, people begin to avoid physical activity, which leads to pain and various other unhealthy conditions.

Dr. Jimenez brings the PUSH-as-Rx System, which is a program designed by a strength-agility coach and physiology doctor with a combined 40 years of experience. The program is the multidisciplinary study of reactive agility, body mechanics, and extreme motion dynamics at its core.

A clear quantitative picture of body dynamics emerges through continuous and detailed assessments of the clients in motion and under directly supervised stress loads. This system with continual dynamic adjustments has helped many of our patients in their weight loss. Plus, they become faster and stronger. Results demonstrate clear improved agility and speed no matter the age. Along with physical training, Dr. Jimenez and the trainers offer nutritional advice.


Amplify The Effectiveness Of Chiropractic Care: Weight Loss Tips

Amplify The Effectiveness Of Chiropractic Care: Weight Loss Tips

Effectiveness: We all know and understand the importance of maintaining a healthy weight. Some individuals do quite nicely at managing their pounds with seemingly little effort, while other struggle constantly.

A recent study by the Center for Disease Control and Prevention (CDC) reports that 78 million American adults suffer from obesity. A person who has sustained an injury or suffers from an illness that affects their back, hips, knees or ankles are especially susceptible to weight gain, because they must deal with limited mobility and the stress of daily pain.

Striving to stay in the ideal weight range for your body type and height provides a variety of health benefits such as adding less pressure on your back and joints, and increasing your range of motion. Patients who receive chiropractic care often enjoy the effectiveness of increased healing by pursuing weight loss.

Successfully fight the battle of the bulge with these four handy weight loss tips to:

Amplify The Effectiveness Of Chiropractic Care

First, Start Small

Replace a couple of negative behaviors with positive ones, and commit to making them stick. Great examples of these are substituting water for soft drinks, eating a high-protein breakfast, or changing out your nightly bowl of ice cream with yogurt.

Simply removing 100 calories a day adds up to a 10 pound weight loss over a year’s time. Small modifications offer the dual benefits of being easier to implement while still showing results.

Next, Keep A Journal

Write down every bite you eat along with the portion size. Listing your food intake provides accountability, which may keep you from noshing on that third slice of pizza or super-sizing those fries.

It also arms you with important intel that will be helpful throughout your weight loss journey. If you hit a plateau, read back through the journal to see what you may have changed over time that caused the scales to stall.

And speaking of scales….

effectivenssDon’t Live And Cry By The Scales

Often, dieters weigh every day and are elated or depressed based on the number on the scales. That’s a roller coaster way to live, and those emotions can cause calorie laden binges!

Plus, daily weighing is not accurate, as fluctuations in water weight are common. Weigh once a week at the most, at roughly the same time each day. A weekly routine gives you a good idea of your success without the stressful up and down of daily weighing.

Decrease Your Sedentary Ways

Even if you are dealing with an injury or medical condition that limits the ability to exercise, you can still probably be less sedentary than you are now. Again, simplicity is the key.

Walk into the bank instead of using the drive through window, stand up to fold clothes instead of sitting down, and take periodic breaks at your desk to stand for a bit.

Ask your chiropractor about any limitations you need to follow, and request stretching exercises as your personal situation permits. Moving more on a daily basis will aid in shedding those extra pounds and keeping them off long-term.

It’s important for individuals to maintain a normal weight range in order to enjoy a healthy life. Chiropractic patients benefit even more from shedding those extra pounds.

By committing to a healthier lifestyle with fewer pounds to carry around, individuals with back and joint injuries will see greater positive impact from their chiropractic visits. Over time, the combination of a leaner body and chiropractic care will bring greater mobility, less pain, and a decreased chance for re-injury to the patient.

How Losing Weight Can Help Reduce Back Pain

How Losing Weight Can Help Reduce Back Pain

Losing Weight: Back pain is one of the most common and most troublesome problems that people experience. Eight out of 10 individuals will struggle with back pain during some point in their life, the US National Library of Medicine reports. Low and chronic back pain can be aggravated by many triggers. Mechanical stress, excessive strain, muscle weakness, poor sleeping position, lack of exercise and excessive weight could all contribute to making the situation worse.

The good news is that chiropractic ranks among the most popular and effective treatment options available today for back pain. Through the chiropractic adjustment, chiropractors not only help ease the pain but also work toward correcting the problem. According to chiropractors, spinal adjustments can deliver even better results when combined with weight loss.

In today�s article, we�ll exam the following:

How Obesity and Back Pain are Related

Individuals that are classified as overweight or obese are much more likely to experience back pain than people that aren�t according to the American Obesity Association.

Obesity prevents individuals from engaging in everyday physical activities, as well as healthy exercises. These are essential for strengthening the core muscles. A stronger core can take some of the burden away from the back, thus making back pain less likely.

In addition, the spinal cord becomes excessively burdened in the case of obese individuals. This is because it�s trying to compensate for the additional weight, which can cause tilting and uneven stress. Both of these can contribute to serious and chronic back pain. Thus the reason obesity is one of the most prominent aggravating factors in the case of lower back pain.

Losing Weight Helps Reduce Back Pain

According to weight loss experts and chiropractors, weight loss can contribute to partial or complete reduction in the back pain symptoms. The research on the connection between weight loss and back pain is still insufficient but numerous practitioners report that they�ve seen cases of patients experiencing serious reduction in pain after losing weight.

Obviously, this occurs because the extra weight is taken off the spine. As a result, the spine doesn�t experience further stress. Especially when a chiropractor realigns the vertebral column through multiple sessions of chiropractic adjustments.

According to the American Spine Society, individuals that stay within 10 pounds of their ideal weight are the ones least likely to experience spinal problems, particularly chronic lower back pain.

Improving Back Health through Chiropractic Care and Physical Activity

The combination of exercise and chiropractic care can produce noticeable, long-term improvements in spinal health.

Besides aiding in weight loss, exercise is also great for strengthening the core muscles and guaranteeing a proper distribution of the body�s weight throughout the spine. Stronger muscles, less weight and better posture will provide amazing long-term benefits for chiropractic patients that suffer from back pain.

If you need more pointers on how to incorporate weight loss and exercise in your daily routine, speak to your local chiropractor. He or she is more than competent to guide you along the way. If you aren�t currently seeing a chiropractor, give us a call. We�re here to help!

The Role Of Epigenetics In Obesity And Metabolic Disease

The Role Of Epigenetics In Obesity And Metabolic Disease

Epigenetic Abstract:

The increased prevalence of obesity and related comorbidities is a major public health problem. While genetic factors undoubtedly play a role in determining individual susceptibility to weight gain and obesity, the identified genetic variants only explain part of the variation. This has led to growing interest in understanding the potential role of epigenetics as a mediator of gene-environment interactions underlying the development of obesity and its associated comorbidities. Initial evidence in support of a role of epigenetics in obesity and type 2 diabetes mellitus (T2DM) was mainly provided by animal studies, which reported epigenetic changes in key metabolically important tissues following high-fat feeding and epigenetic differences between lean and obese animals and by human studies which showed epigenetic changes in obesity and T2DM candidate genes in obese/diabetic individuals. More recently, advances in epigenetic methodologies and the reduced cost of epigenome-wide association studies (EWAS) have led to a rapid expansion of studies in human populations. These studies have also reported epigenetic differences between obese/T2DM adults and healthy controls and epigenetic changes in association with nutritional, weight loss, and exercise interventions. There is also increasing evidence from both human and animal studies that the relationship between perinatal nutritional exposures and later risk of obesity and T2DM may be mediated by epigenetic changes in the offspring. The aim of this review is to summarize the most recent developments in this rapidly moving field, with a particular focus on human EWAS and studies investigating the impact of nutritional and lifestyle factors (both pre- and postnatal) on the epigenome and their relationship to metabolic health outcomes. The difficulties in distinguishing consequence from causality in these studies and the critical role of animal models for testing causal relationships and providing insight into underlying mechanisms are also addressed. In summary, the area of epigenetics and metabolic health has seen rapid developments in a short space of time. While the outcomes to date are promising, studies are ongoing, and the next decade promises to be a time of productive research into the complex interactions between the genome, epigenome, and environment as they relate to metabolic disease.

Keywords: Epigenetics, DNA methylation, Obesity, Type 2 diabetes, Developmental programming

Introduction

Epigenetic mechanismsObesity is a complex, multifactorial disease, and better understanding of the mechanisms underlying the interactions between lifestyle, environment, and genetics is critical for developing effective strategies for prevention and treatment [1].

In a society where energy-dense food is plentiful and the need for physical activity is low, there is a wide variation in individuals� susceptibility to develop�obesity and metabolic health problems. Estimates of the role of heredity in this variation are in the range of 40�70 %, and while large genome-wide association studies (GWAS) have identified a number of genetic loci associated with obesity risk, the ~100 most common genetic variants only account for a few percent of variance in obesity [2, 3]. Genome-wide estimates are higher, accounting for ~20 % of the variation [3]; however, a large portion of the heritability remains unexplained.

Recently, attention has turned to investigating the role of epigenetic changes in the etiology of obesity. It has been argued that the epigenome may represent the mechanistic link between genetic variants and environmental�factors in determining obesity risk and could help explain the �missing heritability.� The first human epigenetic studies were small and only investigated a limited number of loci. While this generally resulted in poor reproducibility, some of these early findings, for instance the relationship between PGC1A methylation and type 2 diabetes mellitus (T2DM) [4] and others as discussed in van Dijk et al. [5], have been replicated in later studies. Recent advances and increased affordability of high- throughput technologies now allow for large-scale epigenome wide association studies (EWAS) and integration of different layers of genomic information to explore the complex interactions between the genotype, epigenome, transcriptome, and the environment [6�9]. These studies are still in their infancy, but the results thus far have shown promise in helping to explain the variation in obesity susceptibility.

There is increasing evidence that obesity has develop mental origins, as exposure to a suboptimal nutrient supply before birth or in early infancy is associated with an increased risk of obesity and metabolic disease in later life [10�13]. Initially, animal studies demonstrated that a range of early life nutritional exposures, especially those experienced early in gestation, could induce epigenetic changes in key metabolic tissues of the offspring that persisted after birth and result in permanent alterations in gene function [13�17]. Evidence is emerging to support the existence of the same mechanism in humans. This has led to a search for epigenetic marks present early in life that predict later risk of metabolic disease, and studies to determine whether epigenetic programming of metabolic disease could be prevented or reversed in later life.

This review provides an update of our previous systematic review of studies on epigenetics and obesity in humans [5]. Our previous review showcased the promising outcomes of initial studies, including the first potential epigenetic marks for obesity that could be detected at birth (e.g., RXRA) [18]. However, it also highlighted the limited reproducibility of the findings and the lack of larger scale longitudinal investigations. The current review focuses on recent developments in this rapidly moving field and, in particular, on human EWAS and studies investigating the impact of (pre- and postnatal) nutritional and lifestyle factors on the epigenome and the emerging role of epigenetics in the pathology of obesity. We also address the difficulties in identifying causality in these studies and the importance of animal models in providing insight into mechanisms.

Review

Epigenetic Changes In Animal Models Of Obesity

rabbit eatingAnimal models provide unique opportunities for highly controlled studies that provide mechanistic insight into�the role of specific epigenetic marks, both as indicators of current metabolic status and as predictors of the future risk of obesity and metabolic disease. A particularly important aspect of animal studies is that they allow for the assessment of epigenetic changes within target tissues, including the liver and hypothalamus, which is much more difficult in humans. Moreover, the ability to harvest large quantities of fresh tissue makes it possible to assess multiple chromatin marks as well as DNA methylation. Some of these epigenetic modifications either alone or in combination may be responsive to environmental programming. In animal models, it is also possible to study multiple generations of offspring and thus enable differentiation between trans-generational and intergenerational transmission of obesity risk mediated by epigenetic memory of parental nutritional status, which cannot be easily distinguished in human studies. We use the former term for meiotic transmission of risk in the absence of continued exposure while the latter primarily entails direct transmission of risk through metabolic reprogramming of the fetus or gametes.

Animal studies have played a critical role in our current understanding of the role of epigenetics in the developmental origins of obesity and T2DM. Both increased and decreased maternal nutrition during pregnancy have been associated with increased fat deposition in offspring of most mammalian species studied to date (reviewed in [11, 13�15, 19]). Maternal nutrition during pregnancy not only has potential for direct effects on the fetus, it also may directly impact the developing oocytes of female fetuses and primordial germ cells of male fetuses and therefore could impact both the off- spring and grand-offspring. Hence, multigenerational data are usually required to differentiate between maternal intergenerational and trans-generational transmission mechanisms.

Table 1 summarizes a variety of animal models that have been used to provide evidence of metabolic and epigenetic changes in offspring associated with the parental plane of nutrition. It also contains information pertaining to studies identifying altered epigenetic marks in adult individuals who undergo direct nutritional challenges. The table is structured by suggested risk transmission type.

table 1(i) Epigenetic Changes In Offspring Associated With Maternal Nutrition During Gestation

Maternal nutritional supplementation, undernutrition, and over nutrition during pregnancy can alter fat deposition and energy homeostasis in offspring [11, 13�15, 19]. Associated with these effects in the offspring are changes in DNA methylation, histone post-translational modifications, and gene expression for several target genes,�especially genes regulating fatty acid metabolism and insulin signaling [16, 17, 20�30]. The diversity of animal models used in these studies and the common metabolic pathways impacted suggest an evolutionarily conserved adaptive response mediated by epigenetic modification. However, few of the specific identified genes and epigenetic changes have been cross-validated in related studies, and large-scale genome-wide investigations have typically not been applied. A major hindrance to comparison of these studies is the different develop mental windows subjected to nutritional challenge, which may cause considerably different outcomes. Proof that the epigenetic changes are causal rather than being associated with offspring phenotypic changes is also required. This will necessitate the identification of a parental nutritionally induced epigenetic �memory� response that precedes development of the altered phenotype in offspring.

(ii)Effects Of Paternal Nutrition On Offspring Epigenetic Marks

baby sleeping holding handsEmerging studies have demonstrated that paternal plane of nutrition can impact offspring fat deposition and epigenetic marks [31�34]. One recent investigation using mice has demonstrated that paternal pre-diabetes leads to increased susceptibility to diabetes in F1 offspring with associated changes in pancreatic gene expression and DNA methylation linked to insulin signaling [35]. Importantly, there was an overlap of these epigenetic changes in pancreatic islets and sperm suggesting germ line inheritance. However, most of these studies, although intriguing in their implications, are limited in the genomic scale of investigation and frequently show weak and somewhat transient epigenetic alterations associated with mild metabolic phenotypes in offspring.

(iii)Potential Trans-generational Epigenetic Changes Promoting Fat Deposition In Offspring

excess nutritionStable transmission of epigenetic information across multiple generations is well described in plant systems and C. elegans, but its significance in mammals is still much debated [36, 37]. An epigenetic basis for grand- parental transmission of phenotypes in response to dietary exposures has been well established, including in livestock species [31]. The most influential studies demonstrating effects of epigenetic transmission impacting offspring phenotype have used the example of the viable yellow agouti (Avy) mouse [38]. In this mouse, an insertion of a retrotransposon upstream of the agouti gene causes its constitutive expression and consequent yellow coat color and adult onset obesity. Maternal transmission through the germ line results in DNA methylation�mediated silencing of agouti expression resulting in wild-type coat color and lean phenotype of the offspring [39, 40]. Importantly, subsequent studies in these mice demonstrated that maternal exposure to methyl donors causes a shift in coat color [41]. One study has reported transmission of a phenotype to the F3 generation and alterations in expression of large number of genes in response to protein restriction in F0 [42]; however, alterations in expression were highly variable and a direct link to epigenetic changes was not identified in this system.

(iv) Direct Exposure Of Individuals To Excess Nutrition In Postnatal Life

modern western lifestyleWhile many studies have identified diet-associated epigenetic changes in animal models using candidate site-specific regions, there have been few genome-wide analyses undertaken. A recent study focussed on determining the direct epigenetic impact of high-fat diets/ diet-induced obesity in adult mice using genome-wide gene expression and DNA methylation analyses [43]. This study identified 232 differentially methylated regions (DMRs) in adipocytes from control and high-fat fed mice. Importantly, the corresponding human regions for the murine DMRs were also differentially methylated in adipose tissue from a population of obese and lean humans, thereby highlighting the remarkable evolutionary conservation of these regions. This result emphasizes the likely importance of the identified DMRs in regulating energy homeostasis in mammals.

Human Studies

anatomy 3D model

Drawing on the evidence from animal studies and with the increasing availability of affordable tools for genome- wide analysis, there has been a rapid expansion of epigenome studies in humans. These studies have mostly focused on the identification of site-specific differences in DNA methylation that are associated with metabolic phenotypes.

A key question is the extent to which epigenetic modifications contribute to the development of the metabolic phenotype, rather than simply being a con- sequence of it (Fig. 1). Epigenetic programming could contribute to obesity development, as well as playing a role in consequent risk of cardiovascular and metabolic problems. In human studies, it is difficult to prove causality [44], but inferences can be made from a number of lines of evidence:

fig 1(i) Genetic association studies. Genetic polymorphisms that are associated with an increased risk of developing particular conditions are a priori linked to the causative genes. The presence of differential�methylation in such regions infers functional relevance of these epigenetic changes in controlling expression of the proximal gene(s). There are strong cis-acting genetic effects underpinning much epigenetic variation [7, 45], and in population-based studies, methods that use genetic surrogates to infer a causal or mediating role of epigenome differences have been applied [7, 46�48]. The use of familial genetic information can also lead to the identification of potentially causative candidate regions showing phenotype-related differential methylation [49].

(ii)Timing of epigenetic changes. The presence of an epigenetic mark prior to development of a phenotype is an essential feature associated with causality. Conversely, the presence of a mark in association with obesity, but not before its development, can be used to exclude causality but would not exclude a possible role in subsequent obesity-related pathology.

(iii)Plausible inference of mechanism. This refers to epigenetic changes that are associated with altered expression of genes with an established role in regulating the phenotype of interest. One such example is the association of methylation at two CpG sites at the CPT1A gene with circulating triglyceride levels [50]. CPT1A encodes carnitine palmitoyltransferase 1A, an enzyme with a central role in fatty acid metabolism, and this is strongly indicative that differential methylation of this gene may be causally related to the alterations in plasma triglyceride concentrations.

Epigenome-Wide Association Studies: Identifying Epigenetic Biomarkers Of Metabolic Health

A number of recent investigations have focused on exploring associations between obesity/metabolic diseases�and DNA methylation across the genome (Table 2). The largest published EWAS so far, including a total of 5465 individuals, identified 37 methylation sites in blood that were associated with body mass index (BMI), including sites in CPT1A, ABCG1, and SREBF1 [51]. Another large-scale study showed consistent associations between BMI and methylation in HIF3A in whole blood and adipose tissue [52], a finding which was also partially replicated in other studies [9, 51]. Other recently reported associations between obesity-related measures and DNA methylation include (i) DNA methylation differences between lean and obese individuals in LY86 in blood leukocytes [53]; (ii) associations between PGC1A promoter methylation in whole blood of children and adiposity 5 years later [54]; (iii) associations between waist-hip ratio and ADRB3 methylation in blood [55]; and (iv) associations between BMI, body fat distribution measures, and multiple DNA methylation sites in adipose tissue [9, 56]. EWAS have also shown associations between DNA methylation sites and blood lipids [55, 57�59], serum metabolites [60], insulin resistance [9, 61], and T2DM [48, 62, 63] (Table 2).

table 2 contdFrom these studies, altered methylation of PGC1A, HIF3A, ABCG1, and CPT1A and the previously described RXRA [18] have emerged as biomarkers associated with, or perhaps predictive of, metabolic health that are also plausible candidates for a role in development of metabolic disease.

Interaction Between Genotype And The Epigenome

Genotype EpigenomeEpigenetic variation is highly influenced by the underlying genetic variation, with genotype estimated to explain ~20�40 % of the variation [6, 8]. Recently, a number of studies have begun to integrate methylome and genotype data to identify methylation quantitative trait loci (meQTL) associated with disease phenotypes. For instance, in adipose tissue, an meQTL overlapping�with a BMI genetic risk locus has been identified in an enhancer element upstream of ADCY3 [8]. Other studies have also identified overlaps between known obesity and T2DM risk loci and DMRs associated with obesity and T2DM [43, 48, 62]. Methylation of a number of such DMRs was also modulated by high-fat feeding in mice [43] and weight loss in humans [64]. These results identify an intriguing link between genetic variations linked with disease susceptibility and their association with regions of the genome that undergo epigenetic modifications in response to nutritional challenges, implying a causal relationship. The close connection between genetic and epigenetic variation may signify their essential roles in generating individual variation [65, 66]. However, while these findings suggest that DNA methylation may be a mediator of genetic effects, it is also important to consider that both genetic and epigenetic processes could act independently on the same genes. Twin studies [8, 63, 67] can provide important insights and indicate that inter-individual differences in levels of DNA methylation arise predominantly from non-shared environment and stochastic influences, minimally from shared environmental effects, but also with a significant impact of genetic variation.

The Impact Of The Prenatal And Postnatal Environment On The Epigenome

fetus modelPrenatal environment: Two recently published studies made use of human populations that experienced �natural� variations in nutrient supply to study the impact of maternal nutrition before or during pregnancy on DNA methylation in the offspring [68, 69]. The first study used a Gambian mother-child cohort to show that both seasonal variations in maternal methyl donor intake during pregnancy and maternal pre-pregnancy BMI were associated with altered methylation in the infants [69]. The second study utilized adult offspring from the Dutch Hunger Winter cohort to investigate the effect of prenatal exposure to an acute period of severe maternal undernutrition on DNA methylation of genes involved in growth and metabolism in adulthood [68]. The results highlighted the importance of the timing of the exposure in its impact on the epigenome, since significant epigenetic effects were only identified in individuals exposed to famine during early gestation. Importantly, the epigenetic changes occurred in conjunction with increased BMI; however, it was not possible to establish in this study whether these changes were present earlier in life or a consequence of the higher BMI.

Other recent studies have provided evidence that prenatal over-nutrition and an obese or diabetic maternal environment are also associated with DNA methylation changes in genes related to embryonic development, growth, and metabolic disease in the offspring [70�73].

While human data are scarce, there are indications that paternal obesity can lead to altered methylation of imprinted genes in the newborn [74], an effect thought to be mediated via epigenetic changes acquired during spermatogenesis.

baby walking in the grass and mudPostnatal environment: The epigenome is established de novo during embryonic development, and therefore, the prenatal environment most likely has the most significant impact on the epigenome. However, it is now clear that changes do occur in the �mature� epigenome under the influence of a range of conditions, including aging, exposure to toxins, and dietary alterations. For example, changes in DNA methylation in numerous genes in skeletal muscle and PGC1A in adipose tissue have been demonstrated in response to a high-fat diet [75, 76]. Interventions to lose body fat mass have also been associated with changes in DNA methylation. Studies have reported that the DNA methylation profiles of adipose tissue [43, 64], peripheral blood mononuclear cells [77], and muscle tissue [78] in formerly obese patients become more similar to the profiles of lean subjects following weight loss. Weight loss surgery also partially reversed non-alcoholic fatty liver disease-associated methylation changes in liver [79] and in another study led to hypomethylation of multiple obesity candidate genes, with more pronounced effects in subcutaneous compared to omental (visceral) fat [64]. Accumulating evidence suggests that exercise interventions can also influence DNA methylation. Most of these studies have been conducted in lean individuals [80�82], but one exercise study in obese T2DM subjects also demonstrated changes in DNA methylation, including in genes involved in fatty acid and glucose transport [83]. Epigenetic changes also occur with aging, and recent data suggest a role of obesity in augmenting them [9, 84, 85]. Obesity accelerated the epigenetic age of liver tissue, but in contrast to the findings described above, this effect was not reversible after weight loss [84].

Collectively, the evidence in support of the capacity to modulate the epigenome in adults suggests that there may be the potential to intervene in postnatal life to modulate or reverse adverse epigenetic programming.

Effect Sizes And Differences Between Tissue Types

connective tissuesDNA methylation changes associated with obesity or induced by diet or lifestyle interventions and weight loss are generally modest (<15 %), although this varies depending on the phenotype and tissue studied. For instance, changes greater than 20 % have been reported in adipose tissue after weight loss [64] and associations between HIF3A methylation and BMI in adipose tissue were more pronounced than in blood [52].

The biological relevance of relatively small methylation changes has been questioned. However, in tissues consisting of a mixture of cell types, a small change in DNA methylation may actually reflect a significant change in a specific cell fraction. Integration of epigenome data with transcriptome and other epigenetic data, such as histone modifications, is important, since small DNA methylation changes might reflect larger changes in chromatin structure and could be associated with broader changes in gene expression. The genomic context should also be considered; small changes within a regulatory element such as a promotor, enhancer, or insulator may have functional significance. In this regard, DMRs for obesity, as well as regions affected by prenatal famine exposure and meQTL for metabolic trait loci have been observed to overlap enhancer elements [8, 43, 68]. There is evidence that DNA methylation in famine-associated regions could indeed affect enhancer activity [68], supporting a role of nutrition-induced methylation changes in gene regulation.

A major limitation in many human studies is that epigenetic marks are often assessed in peripheral blood, rather than in metabolically relevant tissues (Fig. 2). The heterogeneity of blood is an issue, since different cell populations have distinct epigenetic signatures, but algorithms have been developed to estimate the cellular composition to overcome this problem [86]. Perhaps more importantly, epigenetic marks in blood cells may not necessarily report the status of the tissues of primary interest. Despite this, recent studies have provided clear evidence of a relationship between epigenetic marks in blood cells and BMI. In the case of HIF3A for which the level of methylation (beta-value) in the study population ranged from 0.14�0.52, a 10 % increase in methylation was associated with a BMI increase of 7.8 %�[52]. Likewise, a 10 % difference in PGC1A methylation may predict up to 12 % difference in fat mass [54].

fig 2Conclusions

The study of the role of epigenetics in obesity and metabolic disease has expanded rapidly in recent years, and evidence is accumulating of a link between epigenetic modifications and metabolic health outcomes in humans. Potential epigenetic biomarkers associated with obesity and metabolic health have also emerged from recent studies. The validation of epigenetic marks in multiple cohorts, the fact that several marks are found in genes with a plausible function in obesity and T2DM development, as well as the overlap of epigenetic marks with known obesity and T2DM genetic loci strengthens the evidence that these associations are real. Causality has so far been difficult to establish; however, regardless of whether the associations are causal, the identified epigenetic marks may still be relevant as biomarkers for obesity and metabolic disease risk.

Effect sizes in easily accessible tissues such as blood are small but do seem reproducible despite variation in ethnicity, tissue type, and analysis methods [51]. Also, even small DNA methylation changes may have biological significance. An integrative �omics� approach will be crucial in further unraveling the complex interactions between the epigenome, transcriptome, genome, and metabolic health. Longitudinal studies, ideally spanning multiple generations, are essential to establishing causal relationships. We can expect more such studies in the future, but this will take time.

While animal studies continue to demonstrate an effect of early life nutritional exposure on the epigenome and metabolic health of the offspring, human data are still limited. However, recent studies have provided clear�evidence that exposure to suboptimal nutrition during specific periods of prenatal development is associated with methylation changes in the offspring and therefore have the potential to influence adult phenotype. Animal studies will be important to verify human findings in a more controlled setting, help determine whether the identified methylation changes have any impact on metabolic health, and unravel the mechanisms underlying this intergenerational/transgenerational epigenetic regulation. The identification of causal mechanisms underlying metabolic memory responses, the mode of transmission of the phenotypic effects into successive generations, the degree of impact and stability of the transmitted trait, and the identification of an overarching and unifying evolutionary context also remain important questions to be addressed. The latter is often encapsulated by the predictive adaptive response hypothesis, i.e., a response to a future anticipated environment that increases fitness of the population. However, this hypothesis has increasingly been questioned as there is limited evidence for increased fitness later in life [87].

In summary, outcomes are promising, as the epigenetic changes are linked with adult metabolic health and they act as a mediator between altered prenatal nutrition and subsequent increased risk of poor metabolic health outcomes. New epigenetic marks have been identified that are associated with measures of metabolic health. Integration of different layers of genomic information has added further support to causal relationships, and there have been further studies showing effects of pre- and postnatal environment on the epigenome and health. While many important questions remain, recent methodological advances have enabled the types of large-scale population-based studies that will be required to address the knowledge gaps. The next decade promises to be a period of major activity in this important research area.

Excessive Weight Gain, Obesity, And Cancer

Excessive Weight Gain, Obesity, And Cancer

Opportunities For Clinical Intervention

Even though the effects of overweight and obesity on diabetes, cardiovascular disease, all-cause mortality, and other health outcomes are widely known, there is less awareness that overweight, obesity, and weight gain are associated with an increased risk of certain cancers. A recent review of more than 1000 studies concluded that sufficient evidence existed to link weight gain, overweight, and obesity with 13 cancers, including adenocarcinoma of the esophagus; cancers of the gastric cardia, colon and rectum, liver, gallbladder, pancreas, corpus uteri, ovary, kidney, and thyroid; postmenopausal female breast cancer; meningioma; and multiple myeloma.1�An 18-year follow-up of almost 93?000 women in the Nurses� Health Study revealed a dose-response association of weight gain and obesity with several cancers.2

Obesity Increase

obesity man eating oversized burger outside el paso txThe prevalence of obesity in the United States has been increasing for almost 50 years. Currently, more than two-thirds of adults and almost one-third of children and adolescents are overweight or obese. Youths who are obese are more likely to be obese as adults, compounding their risk for health consequences such as cardiovascular disease, diabetes, and cancer. Trends in many of the health consequences of overweight and obesity (such as type 2 diabetes and coronary heart disease) also are increasing, coinciding with prior trends in rates of obesity. Furthermore, the sequelae of these diseases are related to the severity of obesity in a dose-response fashion.2�It is therefore not surprising that obesity accounts for a significant portion of health care costs.

Cancers

obesity cancer-cells microsope el paso tx

A report released on October 3, 2017, by the US Centers for Disease Control and Prevention assessed the incidence of the 13 cancers associated with overweight and obesity in 2014 and the trends in these cancers over the 10-year period from 2005 to 2014.3�In 2014, more than 630?000 people were diagnosed as having a cancer associated with overweight and obesity, comprising more than 55% of all cancers diagnosed among women and 24% of cancers among men. Most notable was the finding that cancers related to overweight and obesity were increasingly diagnosed among younger people.

obesity man sits at beach el paso txFrom 2005 to 2014, there was a 1.4% annual increase in cancers related to overweight and obesity among individuals aged 20 to 49 years and a 0.4% increase in these cancers among individuals aged 50 to 64 years. For example, if cancer rates had stayed the same in 2014 as they were in 2005, there would have been 43?000 fewer cases of colorectal cancer but 33?000 more cases of other cancers related to overweight and obesity. Nearly half of all cancers in people younger than 65 years were associated with overweight and obesity. Overweight and obesity among younger people may exact a toll on individuals� health earlier in their lifetimes.2�Given the time lag between exposure to cancer risk factors and cancer diagnosis, the high prevalence of overweight and obesity among adults, children, and adolescents may forecast additional increases in the incidence of cancers related to overweight and obesity.

Clinical Intervention

obesity doctor in surgery room el paso tx

Since the release of the landmark 1964 surgeon general�s report on the health consequences of smoking, clinicians have counseled their patients to avoid tobacco and on methods to quit and provided referrals to effective programs to reduce their risk of chronic diseases including cancer. These efforts, coupled with comprehensive public health and policy approaches to reduce tobacco use, have been effective�cigarette smoking is at an all-time low. Similar efforts are warranted to prevent excessive weight gain and treat children, adolescents, and adults who are overweight or obese. Clinician referral to intense, multicomponent behavioral intervention programs to help patients with obesity lose weight can be an important starting point in improving a patient�s health and preventing diseases associatedwith obesity. The benefits of maintaining a healthy weight throughout life include improvements in a wide variety of health outcomes, including cancer. There is emerging but very preliminary data that some of these cancer benefits may be achieved following weight loss among people with overweight or obesity.4

The US Preventive Services Task Force (USPSTF)

obesity woman doctors office blood pressure taken el paso txThe US Preventive Services Task Force (USPSTF) recommends screening for obesity and intensive behavioral interventions delivered over 12 to 16 visits for adults and 26 or more visits for children and adolescents with obesity.5,6�Measuring patients� weight, height, and body mass index (BMI), consistent with USPSTF recommendations, and counseling patients about maintaining a healthy weight can establish a foundation for preventive care in clinical care settings. Scientific data continue to emerge about the negative health effects of weight gain, including an increased risk of cancer.1�Tracking patients� weight over time can identify those who could benefit from counseling and referral early and help them avoid additional weight gain. Yet less than half of primary care physicians regularly assess the BMI of their adult, child, and adolescent patients. Encouraging discussions about weight management in multiple health care settings, including physicians� offices, clinics, emergency departments, and hospitals, can provide multiple opportunities for patients and reinforce messages across contexts and care environments.

Weight Loss Programs

obesity young men working out in gym el paso txImplementation of clinical interventions, including screening, counseling, and referral, has major challenges. Since 2011, Medicare has covered behavioral counseling sessions for weight loss in primary care settings. However, the benefit has not been widely utilized.7�Whether the lack of utilization is a consequence of lack of clinician or patient knowledge or for other reasons remains uncertain. Few medical schools and residency programs provide adequate training in prevention and management of obesity or in understanding how to make referrals to such services. Obesity is a highly stigmatized condition; many clinicians find it difficult to initiate a conversation about obesity with patients, and some may inadvertently use alienating language when they do. Studies indicate that patients with obesity prefer the use of terms such as�unhealthy weight�or�increased BMI�rather than�overweight�or�obesity�and�improved nutrition and physical activity�rather than�diet and exercise.8�However, it is unknown if switching to these terms will lead to more effective behavioral counseling. Effective clinical decision support tools to measure BMI and guide physicians through referral and counseling interventions can provide clinicians needed support within the patient-clinician encounter. Inclusion of recently developed competencies for prevention and management of obesity into the curricula of health care professionals may improve their ability to deliver effective care. Because few primary care clinicians are trained in behavior change strategies like cognitive behavioral therapy or motivational interviewing, other trained health care professionals, such as nurses, pharmacists, psychologists, and dietitians could assist by providing counseling and appropriate referrals and help people manage their own health.

The availability of clinical and community programs and services to which to refer patients is critically important. Although such programs are available in some communities, there are gaps in availability. Furthermore, even when these programs are available, enhancing linkages between clinical and community care could improve patients� access. Linking community obesity prevention, weight management, and physical activity programs with clinical services can connect people to valuable prevention and intervention resources in the communities where they live, work, and play. Such linkages can give individuals the encouragement they need for the lifestyle changes that maintain or improve their health.

Nonetheless, cancer is not inevitable; it is possible that many cancers related to overweight and obesity could be prevented, and physicians have an important responsibility in educating patients and supporting patients� efforts to lead healthy lifestyles. It is important for all health care professionals to emphasize that along with quitting or avoiding tobacco, achieving and maintaining a healthy weight are also important for reducing the risk of cancer.

Keto Diet: Ketones vs Glucose for Brain Function | Advanced Nutrition

Keto Diet: Ketones vs Glucose for Brain Function | Advanced Nutrition

Ketosis is a metabolic state where the liver takes proteins and fat and produces molecules to use for energy. Ketosis allows a starving person to survive for days (or even months). Some athletes see improvements while others feel miserable whenever they are in a condition that is ketogenic. Is a ketogenic diet right for you?

 

Ketogenic Diet and the Brain

 

Your brain is about 2 percent of your body mass, even though it requires approximately 20 percent of your basal metabolic rate, more if you are a thinker. Various parts of your brain use different amounts of glucose, and almost twice as much in the morning. You will need to fuel your mind more if you are using your mind working hard through the day and solving problems. If you’re working more on engine control, (state a skill involving precision or equilibrium), then you will use less glucose. Many people can attest to how much energy is used by the brain when challenged.

 

Although sugar is run off by our brains rather than fat, they are also able to run off of ketones as an alternate fuel source. People who market diets tend to be aware the simple fact that an increase in ketones improves repair and the healing of neurons and increases the neurotransmitter GABA. (GABA makes it possible to sleep. It’s also the main neurotransmitter that sleep drugs and antipsychotic drugs influence.) Due to the impact of ketones on the brain, a ketogenic diet can really help those with seizures. Of course, ketosis means you’re burning far more fat, (in the form of ketones), for energy compared to glucose, and also, for the most part, that’s usually great thing.

 

You won’t venture to some harmful diabetic ketosis amount as long as you are generating even only a tiny amount of insulin. So as long as you are not Type 2 or a Type 1, there is nothing to immediately worry about. However, to stay in a state of ketosis, you typically need to eat less than 50g of carbs per day if not less than that. In this state, the body’s functions are based on fat rather than glycogen, and the brain is based on ketones instead of glucose.

 

People wishing to achieve ketosis can not consume an excessive amount of protein. This means no more than 150g per day. Protein could be converted into glycogen and as it may have been mentioned before by professionals, this protein can also be used to make glucose and you would throw the body out of ketosis.

 

Ketones vs Glucose

 

So, should you attempt to achieve this ketogenic state? For many people, they need to do it at least to change their body from insulin resistance. Again, like most things, it is very individualized. If you’re severely resistant this might be your way out of it and about the road to health again.

 

Overall, most people could do much better, (significance become more fit and more healthy), eating less carbs. But when they don’t need to, some people have a tendency to go to the stress and extreme carbs. Many people also fear insulin because everything we read about obesity, cancer, and pretty much any disorder talks about insulin and inflammation. But remember it is all about making just the right amount. Insulin is not a bad guy, just too much of it is. If you don’t make insulin when you ought to be you’re really in a more dire situation than becoming insulin resistant.

 

It typically takes two to three weeks to really shift your body over to fat from using glucose as a main fuel source, which is with an extremely low carb, high fat diet plan. Merely tweaking your diet a little bit won’t do the job. You have to go to the more extreme for a few weeks, and after that you can add in some carbohydrates and determine how you react to them, mentally and physically. The nice thing about changing your body from sugar burning is that you also won’t convert back to being a sugar-burner if you consume too many carbs for a brief period of time.

 

Whether your want to be in ketosis or not is your choice, but you should be able to go days with no carbs (other than veggies) in your diet plan. Carbohydrates should generally only be consumed when you only want to eat them, like pizza, or anything you are into, or once you are training hard or extended.

 

Remember, even if you’re only eating about 2,000 calories per day then 100g of carbohydrates is only 20 percent of your diet plan. You’re getting the identical amount of protein and the fat is left by that around 60 percent, which is grams of fat. (Fat is 9 calories per gram; protein and carbohydrates are every 4 cals.) You are going to want some more carbs, if you are training hard. You’ll need some carbohydrates. If you’re trying to select a diet , training difficult or in any medium to high intensity for a period. Therefore, if you are going to try a diet do it in the off season when you are building a strong base or when you’re in a recovery interval in racing or training hard.

 

On a clinical note, many individuals perform well staying in ketosis for more than a month or two months, max. Health disorders and pain have been a result of being in a ketogenic condition for such a long time. The diet helps people progress mentally and physically, but it can turn on them, without proper understanding. Therefore, if you’re going to go keto, have a rest every few months or so, and see how you operate and feel in and out of ketosis.

10 Common Ketogenic Diet Mistakes for Athletes | Advanced Fitness

10 Common Ketogenic Diet Mistakes for Athletes | Advanced Fitness

Since ketones are a preferred fuel for the heart and the diaphragm, and because a state of ketosis may provide extreme focus and cognitive performance during difficult mental activities, a ketogenic diet can be extremely useful for endurance athletes such as triathletes, distance swimmers, cyclists, marathoners, ultra-runners, etc..

 

Problem is, there are not a ton of tools out there about how highly active people can really get into a state of ketosis.

 

In this guide, author, triathlete, and ketogenic expert extraordinaire Patricia Daly explains how to do things the ideal way. Patricia just finished writing an amazing publication called “Practical Keto Meal Plans For Endurance Athletes: Tips, Tricks And How To’s For Optimizing Performance Using A High Fat, Low Carb Meal Plan”, and she has a wealth of information on this topic.�So in this article, you’re going to get the top 10 mistakes low-carb athletes make.

 

Mistake #1: Being Scared of Fat

 

The ketogenic diet is quite different from other typical diets. The objective of your lifestyle is to teach the body to utilize ketone bodies rather than glucose as the primary source of energy. That is why the quantity is about 75 to 85+ percent of daily caloric consumption.

 

Quite simply, if you operate out quite a bit you probably eat about 2,900 calories a day, of which about 2,300 will come from fat should you follow a ketogenic diet. Fat contains 9 calories per gram, and you will eat 256g of fat daily, based on how much you train of course. To simplify this further: all your intake will be approximately 18 tablespoons, one tablespoon of olive oil, for example, weighs approximately 14g.

 

Mistake #2: Eating Too Much Protein

 

Another mistake novices make is to substitute most of the carbs they used to consume with protein instead of fat. This happen all of the time. The problem is that excess protein intake can result in gluconeogenesis, which is the conversion of amino acids to glucose. This is not what we need on a ketogenic diet, to the contrary, promote the creation of ketone bodies from fatty acids to keep glucose levels low.

 

A lot of men and women are amazed when they start weighing their food according to the proper meal plans and realize how small protein they actually must consume on a ketogenic dietplan. But fat is protein sparing, meaning that a high fat consumption is decreased with by your need for protein.

 

Mistake #3: Carbs Creeping In

 

Carbohydrates can quickly add up if you’re eager to get your veggies, herbs and spices in. They can in fact be found in products that you’d never think contained carbs.

 

Good examples are any processed foods, shop bought salad dressings, milk replacements (many almond and coconut milks have added sugar), tomato sauce, a few meats, such as duck confit, starchy vegetables and even herbal tea, to name only a few. Eating out can be challenging because most restaurants prefer to use dressings, sauces and dips that have added alternative or honey sources of sugar. It tastes nice but is not keto-friendly. Having strong, reliable information is key to carb restriction, especially in the first stages when metabolic alterations occur.

 

Mistake #4: Giving Up Too Early

 

The faster you enter nutritional ketosis, the more side effects you could suffer from initially. The metabolic changes may be striking because every single cell in the body wants to do the change from glucose. Insulin is influenced: Amounts return because of reduced consumption. Insulin allows the kidneys to hold on to sodium. If insulin is at a lower level, the body starts getting rid of excess sodium and also water.

 

This is why it’s so important to guarantee you add sufficient sodium to your diet and keep well hydrated, especially in the first few days of beginning to reduce carbohydrates. This will make certain that you don’t suffer from some of the symptoms of the dreaded “keto flu”: shivers, foggy mind, headaches or nausea are some of the possible symptoms. It is probably more appropriate to call them “carbohydrate withdrawal symptoms” because of the effects on hormonal and electrolyte balance.

 

Things that help to get over these initial obstacles are strong bone broth with good quality salt, a great deal of rest, no extreme exercise and plenty of mineral-rich water, e.g. San Pellegrino. However, the best advice I could give is to take things slowly and not to give up when you are feeling a bit off in the initial phases, provided you’ve done all of the suggested blood tests to exclude any underlying health issues before starting a ketogenic diet.

 

Mistake #5: Scared of the New; Eating the Same

 

Many people feel overwhelmed from the first phases of executing a low carb and ketogenic diet. And because they have very little experience with certain new foods, they still keep eating the same “safe” low-carb stuff. For instance bacon and eggs for breakfast and nuts for snacks.

 

Of course this means that you’re eating low carbohydrate but its often a first priority to always improve their wellness. And this is only possible using a healthy diet. Eating the same things over and over again is dull, it may set you up for having deficiencies and growing food intolerances. This happens quite frequently especially if you’re somewhat worried, your gut function is not optimal or if you’re using medications.

 

Food intolerances may have an effect not only on your stomach health by causing nausea, bloating, diarrhea, constipation or other symptoms, but also in your immune system. The best advice is to continue experimenting with new foods, even if they seem completely strange to you, such as (for example) chicken liver, that is way easier to find and prepare than you’d think. There is a wonderful recipe for each and every food.

 

Mistake #6: Eating Processed Foods

 

This is particularly common for people who have read about the Atkins diet and noticed the products that are sold online and in stores. Yes, they keep you inside the limits that you select and may make life easier but they are also full of artificial flavors, polydextrose, odor, sucralose and other artificial sweeteners that can mess with your psychological and physical health.

 

A rule of thumb: if you wouldn’t have the ability to bake or cook a meal depending on the components list (because you don’t recognize half of them or wouldn’t know where to buy them), then you should stay away from it. Hopefully, with a growing amount of research to verify the advantages of low carb and ketogenic diets there will be plenty of incentives for companies to create snacks based on real foods.

 

Mistake #7: Deficiency Of Planning (And Obsessing)

 

Both absence of preparation and obsessing too much could be stumbling stone. If you don’t plan you’re much more likely to “fail” and give up in your lifestyle modifications. You see, the challenge is that if you realize you haven’t got all you might not find them.

 

Some of the goods that are staples on a low carb or ketogenic diet like olive oil, olives, fatty fish or ghee can only be bought in health stores or on the internet. More and more supermarkets start to inventory them but this depends where you live. Planning makes it more easy to cook in bulk and save cash and time.

 

Evidently, it’s a different story for somebody who follows a ketogenic diet for medical reasons, for instance in the case of epilepsy, no mistakes could be made without a consequence and where the diet has to be nicely calculated. But occasionally people become stressed out about dietary modifications that they wake in the middle of the night and can not go back to sleep. They fear what their next meal could look like ketones could be further increased by them or what to eat on a vacation In cases like this, it’s time to choose a (big) step back, relax, try some recipes without weighing and counting and possibly give it another go after a couple of weeks with a great deal of preparation and support. Stressing about meals can cancel the positive effects of good nutrition out.

 

Mistake #8: Ignoring the Body’s Warning Signs

 

Trainers who obsess over dietary modifications can get caught up in measuring blood sugar and ketones, weighing their meals all the time, producing exact meal programs and they are able to get really scared of eating out where items are out of their hands. In experience, they are also likely candidates to ignore the warning signs of their body.

 

Please remember that you just know your body best and that no meal or instruction program can conquer your innate wisdom and intuition. Take warning signs since you have it in your head to adhere to a specific regime, and do not override them. Low carb and ketogenic diets are not for everybody and if you are feeling worse than before, even after getting over the first symptoms talked about before, then it is probably time to stop and reconsider.

 

Mistake #9: Social Pressure

 

Even years into following a ketogenic diet, many people get opinions from close friends and family regarding this specific nutritional plan and it can sometimes be difficult for individuals to follow their keto diet close when social pressure pushes them to eat a variety of foods outside of their meal plan.

 

Ketogenic diets are still very poorly known even by the medical profession. People don’t understand where a few treats are allowed in moderate quantities, that you can not follow the famous 80/20 rule. You are either in ketosis or you’re not.

 

Mistake #10: Bad Timing

 

And lastly, lets discuss when to start lowering your carbs or attempting to go into ketosis. Please don’t do it a week before your competition of the season or during a period when you’re super busy at the office.

 

The best period of the year to make key adjustments to lifestyle and diet is when you are “off season”. Another fantastic time is before a few preparatory competitions to build towards the most important race. That’s when you see how your body responds to intensity and if the diet doesn’t suit you, you have loads of time to make changes.

Ketogenic Diet: Preventive for Insulin Resistance and Cancer? | Nutrition

Ketogenic Diet: Preventive for Insulin Resistance and Cancer? | Nutrition

Only about 5 to 10 percent of cancer is hereditary, although most cancer scientists have thought that cancer was a disease, states Dr D’Agostino.

 

A metabolic disorder is one that interrupts normal metabolism, the process of converting food to energy on a cellular level. The mitochondria create the energy that our cells will need to perform their job, and these are usually known as the powerhouses of the cells.

 

When carbohydrates (composed of glucose) are consumed, they cause the blood glucose levels to rise. The hormone insulin, responsible for regulating energy use, is secreted by the pancreas because it damages the structure of all proteins, as a high blood sugar concentration is toxic for human tissues.

 

Based on Dr Fettke, we could simply metabolise about one teaspoon (4 grams) of glucose at once and the remainder is stored in the liver and muscles as glycogen, or if this cannot happen, it’s stored as fat.

 

The longer carbs are ingested, the more glucose is produced, the more our body becomes resistant.
Insulin resistance occurs when the body does not respond to insulin properly. This results in increased blood glucose levels, which can not be saved in muscles or the liver must store it as fat, as discussed by Prof Noakes.

 

Relation of Insulin and Health

 

Insulin is consequently the fat storing hormone, which leads to an expanding waist. In case a high carb diet is followed, and if unchecked, it can cause obesity, metabolic syndrome (a combination of hypertension, obesity and hypertension) and to type 2 Diabetes.

 

The long-term impairment which occurs in Diabetes is because of the effect of always high blood glucose levels on a lot of different organs. If blood glucose levels are high, so too will insulin amounts be, and will consequently add to the damage.

 

“The more I read the more I’m convinced of the connection between diet and cancer. A lot hinges on stimulating factors involved in metabolism and cellular division, says Dr Gary Fettkesaid

 

In his study, Dr Elio Riboli notes the higher risk of late onset breast cancer, colon, rectum, endometrial, oesophageal and kidney disorders together with obesity. He explains the link between endometrial cancer and obesity: “Essentially, endometrial cancer is quite closely connected with oestrogen levels. So the tissue there is, the more oestrogens. So there are two outcomes. One is that in the obese, oestrogens are produced by the tissue, converts androgens to oestrogens. The second one is that down-regulating sex hormone binding globulin, insulin, makes oestrogen more bioavailable.

 

According to Dr Gary Fettke, in his lecture at the LCHF Convention before this season, cancer could be tied up with sugar metabolism. Cancer cells cannot use any additional fuel for growth, except for sugar. Without sugar they starve to death. This theory is based upon the Warburg effect, by Dr Otto Warburg, who won the 1931 Nobel Prize for discovering aerobic glycolysis – a flaw in subcutaneous sugar metabolism which diverts glucose away from energy production to cell development and causes fermentation of sugar. In other words, he discovered that cancer cells thrive on glucose and have mitochondria. Dr Gary Fettke also thinks that the problem with modern cancer treatment is that it ignores the glucose metabolism.

 

“We also haven’t fully recognised the institution of diet in the causation of cancer. The problem is sugar, especially fructose, refined fats and polyunsaturated seed oils. The modern diet is inflammatory and it generates masses of oxygen free radicals.”

 

Ketogenic Diet Health Benefits

 

A low carb, high fat Ketogenic diet (that is in nature the Banting diet, but with carb consumption below 25g per day) has successfully treated many different ailments like obesity, epilepsy, Diabetes, Alzheimer’s and cardiovascular disease. Dr Seyfried requires it a single metabolic procedure for a profusion of ailments that are distinct.

 

By maintaining carbs below 25g a day, your system moves from a carb burning state to a fat burning state. Ketones are formed when the liver for energy breaks down fatty acids. Ketosis is reached when ketones are formed through withdrawal of carbs within the body. These compounds are generated throughout metabolism — and are a sign that your body is presently using fat for energy. This process forces the body. Prof Noakes explains this in more detail in the Beginner Banting Online Program, in which you may find the tools to stick to a way of life.

 

“Virtually all the wholesome cells in our body have the metabolic versatility to utilize glucose, fat and ketones to survive, but cancer cells lack this metabolic versatility and require large quantities of sugar and can’t survive on ketones. Therefore by limiting carbohydrates, we could reduce insulin and glucose, and thus limit the key fuel for cancer cell growth.” Says Dr Seyfried. Dr Gary Fettke has a vested interest in this study as he had brain cancer 15 decades ago. He switched to a diet plan and shattered the cancer.

 

Prof Noakes says, “When fighting cancer, just the finest will do. Grass-fed beef, pasture-reared chickens, organic vegetables, etc.. Since hormones and tainted foods have been fed to animals, pesticides sprayed on veg and genetically modified soya and corn is routinely fed to cows and livestock, one must be dedicated to quality in order to avoid the dangers of the substances, highly carcinogenic independently.”

 

What to eat and drink on a Ketogenic diet

 

  • Animal protein
  • Saturated fat
  • Olive oil
  • Avocado
  • Above the ground vegetables
  • Water

 

What to avoid on a Ketogenic diet

 

  • Processed food
  • Fizzy drinks
  • Toxic oils
  • Processed meat
  • Fast food

 

Cancer Fighting Foods

 

  • Tomatoes: cooking enhances cancer-fighting and anti inflammatory properties. Lycopene was found to prevent cancer cell growth in a study in Cancer and Nutrition.
  • Chilli: capsaicin that gives chillies their powerful, spicy personality is anti-bacterial, anti-carcinogenic and anti-diabetic.
  • Cruciferous vegetables: such as cabbage, cauliflower, broccoli, spinach, Brussels sprouts and kale have powerful anti-carcinogens. Cabbage in particular contain anti-oxidants known to help protect against prostate, colon and breast cancers. Broccoli is the only one having a sizable quantity of sulforaphane, an especially potent chemical that boosts the body enzymes and flushes compounds out .
  • Mushrooms: include the amino acid ergothioneine, which is an anti-oxidant and an anti-inflammatory, it protects against free radicals and boosts the immune system.
  • Aubergine: that the epidermis is rich in anti-oxidants known as anthocyanins, which are believed to fight cancer, inflammation, aging and neurological diseases.
  • Turmeric: includes curcumin that’s a powerful anti-oxidant and anti inflammatory. According to Cancer Research UK, it seems to have the ability to kill cancer cells and stop more from growing. It’s the very best consequences on breast cancer, bowel cancer, stomach cancer and skin cancer cells.
  • Berries: the idea of berries as anticarcinogens began in the late 1980s, when it was discovered that berries, and specifically black peppers, comprised ellagic acid, which is believed to inhibited the genesis of tumours.
  • Garlic: belongs to the Allium class of bulb-shaped plants, which also includes onions, chives, leeks, and scallions. It’s an strong and excellent neutraliser of free radicals. It contains good levels of selenium and, in several studies, selenium has been shown to decrease cancers. Phytochemicals in garlic have been found to stop the formation of nitrosamines, carcinogens formed in the stomach.

 

In summary, from the evidence that we have collected from all of the various sources, it’s obvious to see that the link between diet and health is a serious one and that what we consume really has an impact in the long term. Dr D’Agostino goes as far as to state, “let food be thy medicine.”
