Back Clinic Diets. The sum of food consumed by any living organism. The word diet is the use of specific intake of nutrition for health or weight management. Food provides people with the necessary energy and nutrients to be healthy. By eating various healthy foods, including good quality vegetables, fruits, whole-grain products, and lean meats, the body can replenish itself with the essential proteins, carbohydrates, fats, vitamins, and minerals to function effectively.
Having a healthy diet is one of the best things to prevent and control various health problems, i.e., types of cancers, heart disease, high blood pressure, and type 2 diabetes. Dr. Alex Jimenez offers nutritional examples and describes the importance of balanced nutrition throughout this series of articles. In addition, Dr. Jimenez emphasizes how a proper diet combined with physical activity can help individuals reach and maintain a healthy weight, reduce their risk of developing chronic diseases like heart disease, and ultimately promote overall health and wellness.
Women in their early 40s with the highest intake of vitamin D and calcium from food sources may have a lower than average risk of starting menopause before age 45, a recent study suggests.
Taking vitamin D or calcium in supplement form had no benefit in the large study of U.S. nurses, the study team writes in American Journal of Clinical Nutrition, and there may be other substances in dairy foods that also contribute to their apparent protective effect.
“Early menopause can have substantial health impacts for women. It increases their risk of cardiovascular disease and early cognitive decline and osteoporosis,” lead author Alexandra Purdue-Smithe told Reuters Health.
In addition, as women are delaying having kids into their later reproductive years, having early menopause can have a substantial impact on their ability to conceive as they wish, which can have psychological and financial consequences, said Purdue-Smithe, an epidemiologist with the School of Public Health and Health Sciences at the University of Massachusetts Amherst.
“Given that (early menopause) affects roughly 10 percent of women in the U.S. and other Western populations, it felt like a worthwhile problem to start investigating and seeing if there are any potentially modifiable risk factors for it,” she said.
Menopause, when a woman stops menstruating and her levels of hormones like estrogen decline, typically happens between the ages of 45 and 55. Menopause before age 45 is considered “early.”
Vitamin D may be involved in some of the hormonal mechanisms of early menopause, but little is known about how dietary vitamin D and calcium affect the risk, Purdue-Smithe and her colleagues write.
They analyzed data from the Nurses’ Health Study II, a long-term study of more than 100,000 U.S. registered nurses who were 25 to 42 years old in 1989 when they began answering health questionnaires every two years.
The questionnaires were designed to assess the nurses’ lifestyles, behaviors and overall health. Questions about diet were asked five times over 20 years. Researchers followed the participants until 2011, by which time 2,041 women experienced early menopause.
“The women who consumed the most vitamin D from food sources had a 17 percent lower risk of having early menopause as compared to women who consumed the least,” Purdue-Smithe said. The researchers found this association only with dairy sources of vitamin D, like milk, not with non-dairy sources like oily fish.
Women who consumed the most calcium from food sources were also about 13 percent less likely to experience early menopause compared to women who consumed the least calcium, and once again, only dairy foods seemed to provide a benefit.
“Our next direction is to look at actual individual dairy foods and see if there’s something else going on with dairy itself,” Purdue-Smithe said.
The study team also found that taking high doses of calcium in supplement form was associated with a higher risk of early menopause. But the researchers speculate that these women might have been diagnosed with osteoporosis or other conditions that are also risk factors for early menopause.
“Most of what is known about the relationship between calcium and Vitamin D and women’s issues is related to bone health,” said Sandra Arevalo, a dietitian and director of the Nutrition Services and Community Outreach for Community Pediatrics at Montefiore Medical Center in New York.
Lack of Vitamin D and calcium in a woman’s diet, mainly as age progresses, increases her risk of low bone mineral density, osteoporosis and bone fractures, said Arevalo, who wasn’t involved in the study.
The top 10 food sources of calcium are low-fat yogurt, low-fat cheese, sardines, calcium-fortified soy milk, calcium-fortified orange juice, salmon, calcium fortified ready-to-eat cereal, turnips, kale and bok choi, she noted in an email.
The top 10 sources of Vitamin D are cod liver oil, swordfish, salmon, tuna fish, vitamin D fortified orange juice, low-fat vitamin D-fortified milk, yogurt, fortified margarine, sardines and liver, Arevalo said.
Taking a short break from an active lifestyle may do more harm than most people might think, a new study warns.
Just two weeks of sedentary behavior can cause healthy, young people to start losing muscle and develop fat around their organs. And this can increase their risk for conditions such as heart disease and type 2 diabetes that could eventually lead to a premature death, British researchers report.
“What’s alarming about this study is that it was done in healthy volunteers. They were not patients or overweight or had risks for type 2 diabetes,” said lead researcher Kelly Bowden-Davies, from the Institute of Aging and Chronic Disease at the University of Liverpool.
“In 14 days we see small, but significant, changes in markers that predispose people to risk,” she said.
In the study, people were asked to limit their physical activity for two weeks. This included taking the elevator instead of the stairs, taking a bus instead of walking and staying at home more than usual, Bowden-Davies said.
After two weeks of a sedentary life, participants lost nearly a pound of lean muscle mass and gained body fat. The increase in body fat tended to be in the belly, a major risk factor for developing chronic diseases.
In addition, fitness levels dropped sharply, and participants were not able to run for as long or at the same intensity as they had before, the researchers found.
Mitochondrial function, which is the ability of cells to regulate energy, also dropped, but the change was not statistically significant, the study authors noted.
“Globally, people are becoming more and more inactive due to technology, public transport, escalators and elevators, and machines that do what we used to do day to day,” Bowden-Davies said.
The good news is that after going back to an active lifestyle, all these changes were reversed and returned to normal within two weeks, she said.
“The negative effect of an inactive lifestyle can be reversed when we become active again,” Bowden-Davies said.
Going to the gym a couple of times a week, however, won’t reverse the trends of an otherwise sedentary life, she said. Exercise is good, but you need to be active all day, which includes being on your feet and taking walk breaks, Bowden-Davies said.
The problem is more severe in older people who have a sedentary lifestyle and are probably in worse shape than younger people, she said. But it’s never too late to change your lifestyle and see improvements in your health.
The findings were to be presented Wednesday at the European Congress on Obesity, in Porto, Portugal. Research presented at meetings is considered preliminary until published in a peer-reviewed journal.
According to Dr. Minisha Sood, an endocrinologist at Lenox Hill Hospital in New York City, “We’ve known all along that being sedentary will increase the risk of gaining fat and losing muscle, and overall poorer health.” Sood was not involved with the new study but is familiar with the findings.
“What’s novel about this study is that it emphasizes how little time it takes of a sedentary life to start to see those changes,” she added.
But Sood wasn’t sure that going back to an active lifestyle would reverse all of the damage a sedentary period causes. Some of these changes may be permanent, she said.
“If your goal is to be in optimal health, you shouldn’t have a sedentary lifestyle,” Sood said. “An active lifestyle is one where physical activity is built into the day, throughout the day.”
In addition, different types of exercise — like resistance training to counter the aging of muscle and cardio training to increase stamina — are important, Sood said.
“The point is not to hit the gym once or twice a week, but to build an active lifestyle where you are taking walks outside and not sitting all day,” she said.
For the study, Bowden-Davies and her colleagues collected data on 28 healthy, physically active people, average age 25, with a normal body weight. The participants walked an average of 10,000 steps per day and all wore an armband that kept track of their physical activity.
At the start of the study, participants were given a medical checkup that included measuring fat and muscle mass, mitochondrial function and physical fitness.
The exam was done two weeks later after the participants had reduced their physical activity by more than 80 percent, to around 1,500 steps per day.
In addition, the participants kept a journal of what and how much they ate to ensure there were no changes in diet throughout the study, Bowden-Davies said.
Weight-loss balloons swallowed rather than surgically inserted in the stomach were shown to be safe and effective in preliminary trials, according to findings unveiled Thursday at a medical conference.
So-called intragastric balloons have been used for decades to help obese patients shed unwanted pounds. Inflated with water, the devices curb hunger and make it easier to diet by inducing a feeling of fullness.
Up to now, however, they could only be implanted in the stomach surgically, a costly procedure requiring general anesthesia or sedation.
In a small trial led by Roberta Ienca, a researcher in experimental medicine at Sapienza University in Rome, 42 obese patients — 29 men and 13 women — were fitted with balloons that were swallowed before being inflated with liquid.
“A catheter is attached to the balloon, which is folded into a capsule,” Ienca explained to AFP.
A doctor fills the balloon via the tiny tube, which is then removed via the mouth with a tug. “This process takes just a few seconds,” she added.
The body-mass index (BMI) of the volunteers varied between 30 and 45. The threshold for obesity is a BMI of 30.
The balloons remained in the stomach for 16 weeks, during which time patients were put on a low-carbohydrate, low-calorie diet.
At the end of that time, an internal release valve automatically opens and drains the balloon, which is then excreted.
On average, volunteers shed more than 33 pounds, which amounted to 31 percent of excess weight.
No serious side effects were reported.
After the trial, patients were transitioned to a Mediterranean diet, heavy on vegetables and olive oil, and light on protein and starch.
The new technique “appears to be a safe and effective weight-loss method,” Ienca commented in a statement.
Because the swallowable balloon “does not require endoscopy, surgery or anaesthesia, this may make it suitable for a larger population of obese patients not responding to diet or lifestyle treatment.”
It could also lead to significant cost savings, she added.
“In itself, gastric balloons are not a long-term solution for weight loss,” Simon Cork, a researcher in investigative medicine at Imperial College London who was not involved in the study, commented after reviewing the results.
“Nevertheless, gastric balloons are still useful for some patients, and the introduction of a device which doesn’t require surgery to implant is a positive step forward.”
Developed by US-based Allurion Technologies, the system is already marketed in Europe in France, Italy, Spain, Belgium and Greece. It is also available in Saudi Arabia and Kuwait.
The company intends to begin the FDA approval process in the United States soon, Ienca said.
The findings were presented at the European Congress on Obesity in Porto, Portugal, which runs through May 20.
Proponents of intermittent fasting contend that this popular way to lose weight is better than conventional dieting. But this type of diet isn’t necessarily best for everyone, a top expert says.
“Fasting is currently one of the newest diet fads and, while there are studies showing benefits, there are also potential downsides,” Dr. Kent Holtorf tells Newsmax Health.
A recent University of Illinois at Chicago study finds intermittent, or alternate-day fasting, was equal in results to calorie counting when it came to weight loss, along with keeping off the excess pounds.
The study, which followed 100 obese people for a year, found that those who engaged in intermittent fasting lost 6 percent of their body weight, while those who ate a calorie-restricted diet lost 5.3 percent, not a statistically significant difference, the researchers say in JAMA Internal Medicine.
Holtorf is the Los Angeles-based medical director of the Holtorf Medical Group and a founder and director of the nonprofit National Academy of Hypothyroidism. He also has appeared as a medical expert on several TV shows, including “The Today Show,” “Good Morning America,” and “ABC News.”
Here are excerpts from his recent interview with Newsmax Health.
Q: What exactly is intermittent fasting?
A: The idea is to intermittently significantly reduce calories in a strategic way to reduce overall caloric intake instead of eating less per day. One common method is called the 5:2 diet, which involves significant caloric restriction two non-consecutive days per week while eating normally the other five days.
Q: How did this type of diet catch on?
A: Several studies were published showing that severe periodic calorie reduction had been shown to have many benefits including changing gene expression and stimulating cell repair, reducing the risk of Type 2 diabetes, improving cholesterol, lowering the risk of cholesterol levels, reducing heart disease and cancer risk and even extending lifespan.
Q: What do you think of intermittent fasting for weight loss?
A: There is a large amount of research supporting the safety and efficacy of intermittent fasting. If an individual fasts for a designated period of time, weight loss is to be expected as caloric intake has been reduced; however, research finds fasting offers long-term benefits including reduction of inflammation and improvement in mood. For example, a randomized, clinical trial of 71 people who followed intermittent fasting for three months lost an average of 5.7 pounds while the weight of the control group, which didn’t alter their eating habits, lost no weight. Those in the fasting group saw a reduction in blood pressure, body fat, and waist size.
Q: What effect does intermittent fasting have on mood?
A: Going without food for 10-16 hours causes the body to release fatty acids known as ketones. According to Mark Mattson, a senior investigator for the National Institute of Aging, who has done extensive investigation on the health benefits of intermittent fasting, ketones have been shown to protect memory and learning function as well as slow disease processes in the brain. Ketones are also shown to boost the body’s formation of particular stress reducing neurotransmitters, such as serotonin and GABA, which helps you stay calm under stress and have fewer cravings.
Q: What are the drawbacks of using this type of diet for weight loss?
A: While it can be a way to jumpstart weight loss and have health benefits, studies also show that it can permanently reduce metabolism (calories burned per day). The metabolism may not go back to normal when normal eating is resumed unless steps are taken to prevent or reverse the drop in metabolism. Thus, fasting or so-called “yo-yo dieting” can contribute to long-term weight gain, wiping out the short-term health benefits of fasting.
Q: Are there any groups for which this may be a particular problem?
A: This is shown to be more of an issue for women because women’s bodies appear to perceive fasting as more of a threat of starvation and respond by lowering metabolism to survive the perceived famine. This is especially true if a woman has any signs of low thyroid, including low body temperature, depression, cold intolerance, PMS, cold extremities or suffers with fatigue.
Q: So is there any one best diet out there for everyone?
A: Studies show that most diets are successful short-term but most suffer from equal long-term failure. But thyroid evaluation and optimization, if low, can increase the likelihood of successful weight loss whether via fasting or other diet plan.
Eating red meat increases your risk of death from nine diseases, according to a new study.
Researchers tracked the diet and health of more than 536,000 people, ages 50-71, for an average of 16 years, The New York Times reported.
Compared with the one-fifth who ate the least red meat, the one-fifth who ate the most were 26 percent more likely to die from cancer, heart disease, respiratory disease, stroke, diabetes, infections, Alzheimer’s disease, kidney disease and liver disease.
People who ate the most white meat were 25 percent less likely to die from various causes than those who ate the least white meat, according to the study in the journal BMJ.
“This is an observational study and we can’t determine whether red meat is responsible for these associations. But we have a 16-year follow-up, and we had the numbers to look at different causes, and we can see that it’s happening” said lead author Arash Etemadi, an epidemiologist at the U.S. National Cancer Institute, The Times reported.
A coffee, a caffeinated and an energy soda proved a deadly combination for a South Carolina teenager who died within two hours of consuming them, triggering warnings about the risks of caffeine overdose.
Davis Allen Cripe died on April 26 from a “caffeine-induced cardiac event causing a probable arrhythmia,” the Richland County coroner’s office in the southern US state wrote in a statement.
Two hours before he collapsed, Cripe drank a cafe latte, large Diet Mountain Dew and an energy drink.
Richland County Coroner Gary Watts noted Tueday that such occurrences are “highly unusual.”
“It was mainly due to the time period that he ingested a rapid amount of caffeine that affected his heart,” Watts told The Post and Courier, adding that Cripe had collapsed just 15 minutes after taking the energy drink.
The US Food and Drug Administration recommends that adults consume no more than 400 mg of caffeine per day, which is equivalent to four or five cups of coffee.
“While adults should be mindful of their caffeine consumption, it’s important for parents to know the risks of children and adolescents consuming caffeine,” Jill Michels of the Palmetto Poison Center said in a statement.
“Take the time to talk with your children about the dangers of caffeinated drinks.”
At a news conference on Monday, the boy’s father said his son was very careful about drugs and alcohol.
However, “it wasn’t a car crash that took his life. Instead, it was an energy drink,” Sean Cripe said.
While energy drinks account for just a small segment of the non-alcoholic beverages industry, they are very popular with young people.
Health experts have expressed concern about the drinks’ high caffeine content, which can cause arrhythmia and raise blood pressure in young people.
Energy drinks can contain up to 240 mg of caffeine, according to a 2012 Consumer Reports study.
Conventional knowledge wants us to believe that athletes must eat a high carb diet in order to function at optimum levels. While many people believe this, nothing could be further from the truth. Ben Greenfield conducted extensive tests on himself to prove that it is possible to be a fat burning athlete, and that being a high carb athlete should be a thing of the past.
Ben�s analysis was very detailed and impressive: he had blood work, biopsies, urine and stool samples taken before the study began. He then walked on the treadmill for three hours and retook the blood work, biopsies the urine, and the stool samples, then analyzed the data. The study was called The Faster Study, and the data is available via PDF for those interested in looking at his findings and Ben�s write-up on the experience can be found here.
The Faster Study
When I asked Ben why he did the study, he said it was for his own selfish reasons. He said he was training for an Ironman triathlon at the time and wanted to go faster or at least maintain his speed for longer periods without experiencing the deleterious effects that chronically elevated blood sugar�can cause. He also wanted to avoid the potentially unsettling effects that carbohydrates fermenting in your gut can cause.
Ben also had another incentive: he was diagnosed as having a 17% higher than normal risk for Type 2 diabetes. As a result, he needed to figure out a way to complete an Ironman triathlon without going the traditional route of fueling with gels, bars, and energy drinks.
I can attest that his theory works because I tried it myself: while on an 18 hour intermittent fast, I went on a 3 hour bike ride. By the time I got home, it was 22 or 23 hours before I�d eaten one bite of food, and to everyone�s surprise, I didn�t bonk. Everyone on the ride that day was a seasoned athlete and eating constantly. I was the only one not eating, yet had plenty of energy, even after 20 hours without food. Ben proved that in a laboratory and I successfully tested his hypothesis in a real life situation.
The Faster Diet
In preparation for his experiment, Ben followed a diet of 80 to 90% fat and 5 to 10% carbohydrates. His protein intake would vary depending on the day�s activities. For example, protein intake would be approximately 20% on days he�d run or do weight training. On average, the majority of his diet was fat based. He jokingly said he was banned from Italian restaurants during this time.
While on his high fat/low carb diet, Ben did two ironman triathlons that year (Ironman Canada and Ironman Hawaii.) He stresses that that a low carbohydrate diet does not mean a zero carbohydrate diet. Using Ironman triathlon as an example, participants may be out competing for ten or more hours. When passing someone the on the bike, a person may go from their normal race pace of 250 watts up to 400 watts for a few moments. This surge of energy being exerted can cause a pretty significant glycolytic shift, resulting in the body needing to burn through a high amount of carbohydrates.
Ben took in about a quarter of the amount of carbohydrates that he�d normally consume during the actual event, along with ample amounts of easy to digest proteins, amino acids, easy to digest fats, and medium chain triglycerides. After his triathlon season was completed, Ben added exogenous ketones�to his diet in powder form to increase ketone levels. Ben admitted that he finds the ketones extremely beneficial and says he wish he�d known about them while training for previous triathlons. Personally, I have experimented with exogenous ketones in my own fat burning regime, after learning more about how they work during my interview with Dominic D�Agostino (watch the interview here.)
Study Findings
During that triathlon season, Ben conducted quite a few studies, with a few standing out in particular. In this test, a microbiome analysis was conducted to see how the gut differs between someone who follows a high-carbohydrate diet and someone who follows a high-fat diet.
Fat biopsies were taken both before and after exercise to see to see if his actual fat tissue make-up was any different. Tests were also conducted to see if there was any difference in the ability of his muscles to store carbohydrate and how quickly the muscle would burn through carbohydrates. A resting metabolic test was conducted, which is an analysis of how much fat and carbohydrate is burned at rest. And another measurement was taken to determine how many carbohydrates, fats, and calories are burned during exercise.
What makes these tests interesting is even though most physiology textbooks claim that the average person will burn about 1.0 grams of fat per minute during exercise, the athletes who followed a ketogenic or low-carbohydrate diet for close to 12 month were experiencing fat oxidation values of closer to 1.5 to 1.8 grams of fat per minute. This is significantly higher than what experts expected.
Initially, there was some confusion pertaining to this study because it was called � The Faster Study.� Critics would say Ben wasn�t going any faster on the high fat/low carb diet than those on the high carb diet. What they neglected to understand was the purpose of the study wasn�t to go faster than those on high carb diets. Instead, the goal was to maintain similar speeds while limiting (and possibly eliminating) the chronic fluctuations and elevations of blood sugar.
Ben�s thought process behind the study was simple: If he could go just as fast by eliminating sugars, why not do it? If he slowed down or felt his energy levels being depleted, he�d be forced to ask himself the following questions as an endurance athlete:
What kind of balance did he want between health and performance?
How many years of his life was he willing to sacrifice in exchange for going just a little bit faster?
How much pressure was he willing to put on his joints?
As it turns out, Ben could go just as fast on a carbohydrate-limited diet.
Go Just as Fast, Live Longer
While people are focused on getting faster, the ultimate goal should be to go just as fast and live longer doing it. Unfortunately, many high-carb athletes have a wide assortment of health problems, which can range from joint problems to life threatening emergencies such as heart attacks. Many of them are dying prematurely and don�t realize a contributing factor to their ailments is the high carb diet they had been following for years. Ironically, many athletes are thin but show evidence of degenerative disease indicating years of inflammation and oxidative stress�caused by repeated glucose and insulin spikes. We know this damage is oxidative, is harmful to the cells, and causes premature aging.
There are many studies with research illustrating how endurance sports increase oxidation and aging, but I believe as more research is done this belief will change. Studies by Ben and others show that a fat-adapted endurance athlete does not have the same levels of oxidative stress as high carb endurance athletes. At age 50, I have 8% body fat and can exercise for hours without ingesting carbohydrates because, like Ben, I�m very efficient at fat burning.
I firmly believe Ben�s study proves that people who are efficient at fat burning can burn well over one gram of fat per minute of exercise, whereas before it was believed one gram (or less) was a more realistic number. It should be noted that in order to burn that much fat, a person has to be fat adapted. It�s impossible to accomplish this level of fat burning on a high-carbohydrate diet (read more on how to get fat-adapted here: Part 1 and Part 2.)
Fat Adaption: A trick to Accelerate the Process
Becoming an efficient fat burner takes time. Many of the athletes that Ben coaches have been on a high fat diet for twelve months or more. While the greatest benefits aren�t felt for several months, a person can experience lower blood sugar levels and less oxidation within a few short weeks of starting a high fat diet. However, in order to achieve the mitochondrial density necessary for producing a lot of ATP on a high-fat diet while exercising, a person will need to follow a high-fat diet for at least a year.
It can take anywhere from 6 months to 2 years for a person to become fully efficient at burning fat. While some may balk at how long it can take, it�s not long when compared to the time it may take to become proficient in a sport, learning to play a musical instrument, or getting a college degree.
Adjusting to a high fat diet takes time and patience. To accelerate the process, one can choose to eat within a compressed time window, a strategy known as intermittent fasting. Intermittent fasts can range from 14-24 hours with just liquids being consumed. Intermittent fasting can be a challenge for beginners as the body begins to adapt, but becomes easier with each subsequent fast. I intermittent fast daily and must say it�s been the great contributor to my overall cellular health.
Some side effects beginners may experience while intermittent fasting the first few times may include the following
Fatigue
Nausea
Vomiting
Diarrhea
Headaches
Lack of focus
Bad breath
Lethargy
Joint pain
Minor depression
These side effects are normal as the body eliminates various toxins. Drinking pure water�helps to alleviate some side effects and quickly remove them from the body via urination. Staying focused on the long term is key when embarking on these changes.
Occasionally, I will receive emails from my clients or the doctors of my clients, telling me they are keto-adapted, but they�re not burning fat, they don�t notice any significant changes in their bodies, and they haven�t lost any weight. I explain how this is normal, and the body has to adjust. It takes time for the body to realize it is not starving and that it can begin to burn its own fat for energy. Using my wife as an example, it was almost a year before she was able to use her fat storage for energy. Now, she�s an efficient fat burner and finds it much easier to stay lean.
Not All Fat is the Same
An important aspect of being efficient at fat burning is the type of high fat diet you follow. A plant-rich, ketogenic diet not only limits oxidation and free radical production, but it also causes an increase in stable energy sources due to high fiber content. Having high levels of plant-based chlorophylls in the bloodstream also has the potential to increase ATP production beyond what we fully understand in nutrition science.
Ben encounters many people who follow the Bulletproof Coffee type of approach:
Three cups of coffee with grass-fed butter and MCT oil during the day
Coconut milk with some coconut flakes and some chocolate stevia
Fatty grass-fed steak for dinner
Macadamia nuts for a snack
The problem with this type of diet is there�s very little plant matter eaten, and plants are an integral part of a healthy high fat diet.
Ben Greenfield�s Diet
Ben eats an astonishing 20 to 25 servings of plants per day. He has an enormous backyard garden and eats kale, butter lettuce, bok choy, mustard greens, cilantro, parsley, and tomatoes daily. He says these foods do not count towards his total daily carbohydrate intake, and that eating a high-fat diet does not mean that you�re not eating plants. It�s the opposite. �I eat a lot of plants, a lot of fiber, and it makes a night-and-day difference.�
In order to get 20-25 servings Ben eats huge salads and drinks nutrient dense smoothies. He�ll drink one or two large smoothies a day, using a powerful blender that blends everything from the pit of an avocado to an entire bunch of kale. A sample smoothie includes the following ingredients:
Six to eight different plants (both wild plants and herbs)
Lunch. Lunch is a salad in an enormous bowl filled exclusively with vegetables. Ben will spend 30 to 60 minutes chewing each bite 20 to 25 times and �eating lunch like a cow while I go through emails and things like that during lunch.�
Dinner. Another big salad.
Snack. Snacks are normally smaller versions of the smoothie�he had for breakfast.
He stresses that his salads are extremely large and he prefers thicker smoothies: �If you were to see the size of my salads and the size of my smoothies, you would be shocked. You�d think I would be morbidly obese, but if you dig in and you look at it, it�s really just mostly plant volume. That�s generally what I do, salads and smoothies. I make them so thick I need to eat them with a spoon because I really like to chew my food. Yeah, I�m a smoothie and a salad guy.�
He goes on to say �When I look over the blood and bile markers of people following a high-fat diet, a lot of times I see really high triglycerides and really low HDL, which is often what you�ll see in someone who is eating a ton of animal fats without many plants or without much fiber. I�ll see a lot of CO2 and really low chloride levels, an indicator of a net acidic state, and a lot of biomarkers that aren�t necessarily favorable and that can be a result of a high-fat diet done improperly. I think that�s one important thing to bear in mind, too, is that you don�t want to necessarily eschew plant intake and vegetable intake; you just want to ensure that those are accompanied primarily by healthy fats and oils rather than accompanied by high amounts of protein and starches.�
When it comes to good fats, Ben prefers the following:
Animal fats are eaten sparingly. He�ll eat a grass-fed steak and wild fish a couple of times a week. He also likes pemmican, which comes in a tube that he can snack on while flying or if he needs a quick snack on the go.
When Ben was a bodybuilder, he would aim for 200 grams of protein per day but now only consumes between 100 to 120 grams. Currently, he weighs about 180 pounds and consumes between 0.5 and .8 grams of protein per pound of body weight. He feels this is the amount is sufficient to avoid any loss of muscle.
Ben says he has excellent colonic health. Since he started the high fat diet four years ago, he doesn�t have the fermentation, gas, bloating, or constant gas that many endurance athletes have. He also believes the high fat diet offers a lower risk for things like small intestine bacterial overgrowth (SIBO) and fermentation in the gut.
Diet Variation
In addition to eating a variety of plant based foods, an important eating concept that I have written about is something I like to call �diet variation,� which is basically emulating what our ancestors have done: They were forced into different diet variations seasonally, and in some instances, weekly.
When we look at the Hunza people as an example, they were relying mostly on plant food in the summers to survive. During the cold winter months, vegetables and fruits were scarce or nonexistent, and as a result, they were forced to eat higher-fat foods (meats and animal fats). Over time we can see a pattern: there would be long stretches where their diet consisted mostly of vegetables (summer,) then extended periods of time where their diet was mainly meat products (winter.) This type of seasonal eating created a variation in their diet they had little control over. Today, we have the ability to vary our diet at all times, which can work for us and against us.
I go into ketosis every summer and eat more good fats and protein than I do in the winter, when I eat more healthy carbs. Like Ben, I�m very fat adapted, yet still able to stay in ketosis while eating a lot of plants in my diet. I intermittent fast in the morning and by the afternoon I�m burning high ketones.
One of the popular diet trends these days is the Paleo Diet, where a person is instructed to eat large amounts of protein. Quite frankly, I am not a fan of this diet. I have read many studies on high-protein diets and feel they are not healthy. Eating too much protein can cause weight gain, extra body fat, increased stress on the kidneys, dehydration and other health issues.
If you include the dangers of eating grain fed beef instead of the healthier grass fed beef, we can clearly see how the Paleo Diet could be a recipe for disaster. I tell people as a general rule, eating protein that is equivalent to half your body weight (considering that you�re not morbidly obese) is usually safe and practical. Athletes like Ben (and those who do a lot of strenuous physical exercise) can consume more protein than the average person and utilize it safely. These individuals may require 0.7 to 0.8 grams of protein per day, while the average person only needs .55 grams per day.
Fasting
Ben goes on a 24 hour fast once a month, just to �clean things out a little bit.� He will start the fast Saturday at lunchtime end it at lunchtime on Sunday. Or, he�ll skip dinner on Saturday night and won�t eat again until dinner on Sunday. He�ll drink water, coffee�and tea primarily during the fast, and kombucha on occasion. He also goes on a 12-16-hour intermittent fast daily. The majority of the fast is overnight where he�ll finish dinner around 7:00 or 8:00 p.m. and eat breakfast sometime 9 and 10:30 a.m. During the daily fast, Ben will perform a few low-level exercises in the morning: yoga, foam rolling, or mobility work are exercises of choice.
In addition to daily intermittent fasting, Ben believes a likely factor that helps him to stay lean and maintain a low body fat percentage is taking cold showers. He likes to do one of the following daily:
Fast, perform a low intensity exercises then take cold shower or�
Fast, sit in a sauna for a few minutes, followed immediately with a cold shower.
Ben�s Exercise Regimen
Ben is active all day, but in an unconventional way:
�I generally am active all day long. Today, while I�m writing, doing consults, and reading emails, I�ll walk somewhere in the range of three to five miles at a low intensity like I am right now. When I get up in the morning, I�ll generally spend 20 to 30 minutes doing some deep-tissue work and some mobility work, some foam roller, and some band work for traction on my joints. By the time I get to the end of the day, I�ve been mildly physically active for six to eight hours at just very low-level intensity.
�At the end of the day, I�ll throw in 30 to 60 minutes of a hard workout. That might be a tennis match. It might be kickboxing or jujitsu. It might be some kind of an obstacle course workout with sandbags, and kettlebells, and things like that. It might be a swim. It varies quite a bit, but generally it�s 30 to 60 minutes of something hard in the afternoon to the early evening, then up until that point, low-level physical activity all day long. It�s just tough to quantify because I�m always moving. As far as a formal workout, it comes out to about 30 to 60 minutes a day. We�re talking about a workout where the average heart rate is very close to maximum heart rate, so like a puke-fest style workout. That�s pretty draining from an energy standpoint. Generally, for me to do daily�exceeding 16-hour fasts daily�that gets tough.�
What�s Next For Ben?
Ben is an outdoorsman and wants to experiment with living on the land:
�I�d like to look into more of an ancestral application, a more practical application. I would like to look a little bit more into persistence hunting, something closer to where I live where I�d be going after elk or moose or something like that, preferably in the snow where tracking is a little bit easier, but seeing if it�s doable.
�A five to eight day hunt is realistically what you�re looking at with a bow, or with a spear, or with a close-range weapon, and seeing if it�s possible to actually go and get your own food in the absence of food, just to begin to get people thinking about the state that we live in, the culture that we live in where food is just constantly readily available. What would happen if we didn�t have food but we had to figure out a way to feed ourselves?�
Ben also shares the outdoor life with his children: One day week in the summers, they can only eat the plants they find outside in the garden until dinner. As part of their childhood, he wants them to learn how to take care of themselves. They can use the stove and the blender, stuff like that, but they can�t use ingredients from the pantry, or from the refrigerator. It�s all based on plants.
While many people may think this way of thinking and living is extreme, Ben believes more people can benefit from it if they stay open minded and give it a try:
�I would like to get people more aware of that type of practice because it really goes quite handily with the things that we�ve talked about�fasting and ketosis, and denial of modern food sources and starches and instead just learning how to take care of yourself. I think that there�s a lot of lessons to be had from a health and survival standpoint, and so plant foraging, spreading our message, as well as the potential of seeing the persistence hunting in the absence of any significant sources of calories, to be able to take what allows one to, say, do an Ironman Triathlon with very little calorie intake and then turn that into a more practical level like going out and getting your own meat and stuff. Again, without carrying a bunch of power-bars out with you, I think that�d be a cool little adventure to embark upon.�
A Life of Fitness
Ben believes fitness is a lifestyle, and everyone can incorporate fitness into their daily activities:
If you work in a traditional office setting, put a kettlebell underneath your desk.
Get one of these stools that you lean back on rather than sitting down.
Every time that you go to the bathroom have a rule that you�ve got to do 50 air squats.
�Start to work in those little things throughout the day. You�d be surprise at how fit you can stay and how prepared you can be for a big event without necessarily neglecting your family, your friends, hobbies, or work.�
