What about eating frequency? How often should we eat?

Should we eat 3 Square Meals?

Or should we eat 6 Small Meals?

Or should we eat only inside a window of 8 hours or 5 hours?

Or should we, intermittently, have days with only one small meal, or even zero food in a total water fast?

Or should we eat whenever we feel Hunger?

Each of these “Diets”, “Non-Diets”, “Ways-of-Eating”, or “Lifestyles” claims that Scientific Research supports their individual position.

So what DO we do?
The following article by Dr. Yoni Freedhoff of WeightyMatters, supports my own personal position on this question.

Does New Study settle the
3 Square vs. 6 Small vs. the 8 hr Diet Debate?

So this month yet another study in a never-ending line of studies looking to compare the impact of meal frequency on fullness and biochemistry came out. This one suggested that small frequent helped decrease energy intake in normal weight men.

Honestly I pretty much disregard all of these studies.

Not because I'm doubting or questioning their results, just that I don't think their results really matter.

What I mean is that all of these studies fail to address the practical aspects of living with their recommendations, and as a clinician, that's really all that matters to me.

I've seen people controlling calories, loving life and preserving health with 6 small meals daily. I've seen people do the same on 2, 3, 4, and in some cases even 1 meal a day.

Regardless of the research that comes out, what matters more than what a physiology paper says is how you personally feel.

In my office we do tend to start people on small and frequent meals and snacks. But if that doesn't suit or help the individual we'll shift to 3 square meals. We've also recommended the intermittent fasting style that's suddenly finding some traction on the diet book shelves.

You need to find a life that you enjoy, and just because a new study or diet book suggests there's a "better", or "right", way, if you don't happen to enjoy it, it just isn't going to work.

The specific new study referred to is: Psychology and Behavior

According to all of the scientific research I’ve read, when we get right down to it, any actual “Health” or “Metabolic” Benefit Differences between all of these eating plans are truly miniscule, and therefore, not even worth the individual effort of personal consideration. The question to consider is which one can we DO?

I ask myself:

• Which Eating Behavior will work for ME in MY weight-loss or maintenance efforts?.
  
• Which Behavior will allow ME to consistently eat less than, or the same as, the amount that My body uses for energy?
  
• Is one Eating Behavior more manageable for ME than another?
  
• Which one can I consistently stay on?
  
• Can I live with one of these Behaviors as a lifetime Habit?

 "The Fast-5 Diet and the Fast-5 Lifestyle" (2005) by Bert Herring M.D. is a weight-loss and weight-maintenance plan based on the concept of intermittent fasting. It consists of a single rule: limit calorie intake to no more than five consecutive hours in each day. The Fast-5 Lifestyle is an indefinite continuation of that diet for weight maintenance after the weight loss goal has been reached.

Dieters using the Fast-5 diet fast for nineteen hours total each day. This nineteen hours includes sleep. After the nineteen hours of fasting is complete, dieters then have five hours in which they can eat whatever they choose.

The suggested eating window is from 5pm - 10pm, but Dr. Herring indicates that the nineteen continuous hours of fasting time is the key to the diet's effect, and that the five-hour eating window may be set whenever it is most personally convenient.

The Fast-5 approach does not stipulate a calorie intake level. It relies on the eating schedule's effect of correcting appetite to determine proper intake, but doesn’t discourage the addition of a calorie counting approach. The Fast-5 Diet also does not specify food content or forbid any foods, allowing the approach to be used with any dietary preference.

The Fast-5 diet was developed based on the personal results Dr. Herring experienced while working at the National Institutes of Health and incorporates estimates of the eating schedule of ancient hunter-gatherer humans who ate without benefit of food storage or refrigeration.

Dr. Herring distinguishes Limbic hunger, which comes from that part of the brain that connects primitive drives, emotion, and memory, from Somatic hunger, which is the sensation of discomfort in the stomach area that is commonly known as hunger, or hunger pangs. Somatic hunger is the result of the interaction of many hormonal and nerve signals and incorporates more information than just whether the stomach is empty.

He says that Limbic hunger is the reason why it is hard to eat only one potato chip. Eating one chip triggers more appetite because primitive limbic signals tell the brain we should eat as much as we can while food is available. This leads to more eating, connecting in a vicious circle that doesn’t stop until the bag of chips is empty. The ancient instinct takes control of behavior, ignoring higher thinking and preferences. Limbic hunger in a land of plenty causes one to eat too often and too much.

Two ways in which the Fast-5 plan is helpful, according to Dr. Herring, is that:

• Having a 19 hour short-term fasting period eliminates the potential…during that time period, for eating to-drive-more-eating, and keeps limbic hunger from taking over control.
  
  
• 19 hours of daily fasting enhances the body’s fat-burning capabilities by providing a long period every day when the body’s fat-burning machinery is switched on and stays on. Once the body is using energy from stored fat, rather than from fresh glucose absorbed from digesting food, continuous fat burning is more efficient than when the body flips back and forth from fat to glucose and back again. Also, changing back and forth causes fluctuations in the levels of hunger related hormones (insulin, ghrelin, leptin and more) resulting in the sensation of hunger.

I have had brief and limited experiments with the Fast-5 diet, usually in combination with alternate day eating. I am currently involved in another entirely different Fast-5 experiment.

My normal pattern is to wake up about 4am. and go to sleep about 8pm.

During my past experiments, I chose an eating window of 2pm until 7pm, which in my lifestyle is the equivalent of a 5pm to 10 pm window. This did not work well for me because during the entire Fast-5 dieting experiment I found myself simply killing time every day until 2pm, totally focused on wanting to eat, while I did everything possible to distract myself from food until the time finally came for me to eat.

I am a morning person, and normally prefer my breakfast and lunch over my dinner, so with a late-in-the-day window, my preferred mealtimes were not available to me.

I had difficulty in getting myself to set a morning 5 hour window because of the idea of how hard I might find it to go without food during the long afternoon and evening period.

Recently, I decided to try Fast-5 with a morning window from 9am to 2pm and found that this suits my body and personality a great deal better. A five hour window from 9am to 2pm allows me to eat at my preferred mealtimes. It also seems that so far…..I, personally, feel less physical hunger and less desire to eat after 2pm between lunch and bedtime, than I do in the mornings before 2pm. Whether this will continue to be the case over time, is something that I just don’t know.

My present Fast-5 experiment is in the early stages, and is combined with calorie counting and other dietary preferences. I haven’t set a time-period for how long I’ll continue on with it. Right now, it’s day-by-day, and I’m deciding each morning whether or not to go forward with it.

I know that there are times when I find eating zero food easier than eating a tiny amount of food, and other times when this isn’t true for me. I’m interested in learning more information about that difference. I’m also curious as to whether this way of eating will cause me to eat less overall, for more than just a few days, and if that behavior will provide me with any weight-loss results. I mention this just as another example of how I treat Dieting as a Hobby.

"We never repent of having eaten too little.”
Thomas Jefferson (1743 -1826)

When Jefferson was the principal author of the Declaration of Independence in 1776, he was around 33 years old, and he lived until age 83 during a time when food was not as easily obtainable. Even though he did not experience our modern readily-available-highly-processed-food world he seemed to understand the value of eating less.

How little is "too little"?

I’ve noticed that people who eat far too much, seem to spend a lot of time worrying about eating too little. Why do people who are obese, or even merely overweight, fear eating too little, and just how little is too little anyway?

Many overweight and obese people appear to have an irrational fear of starvation mode.
However, one really can't eat too little for weight loss - Starvation Mode (the way most dieters define it) is a Myth.

"Starvation mode" is a phrase that gets thrown about loosely. Many people think that eating below 1000 to 1200 calories a day, will cause their metabolism to slow down so much that their body will stop losing weight. The reality is that until a male has only 5% excess body fat, or a female has only 10% excess body fat, it is very unusual for a person to go into “starvation mode”.

When it seems impossible for a dieter nearing goal to lose weight, they assume their metabolic process is slowing down, and think that they are “in starvation mode”. However, people with extra weight obtainable to oxidize, can oxidize extra body fat per second. The less human body fat one has, the less fat oxidized for each moment. So as one gets closer to the body’s individual reduction limit of human body weight, the slower one will burn up what body fat one has. This is why taking off the final 10 pounds happens very slowly, NOT because one is wrecking one’s metabolic process with an aggressive diet regimen.

By the way, I’m using the term…”excess fat”… to define the entire genetic make-up of an individual body, not “troublesome” fat on specific body areas that one wishes were leaner… like stomach or thighs, etc. It is not uncommon for someone who is “normal weight” or even “underweight” to be unhappy with the way their own body’s necessary fat is genetically distributed.

The article quoted below makes a number of good points:

Are You In The Starvation Mode or Starving For Truth?

Recently we discussed the myth that dieting can lead to an eating disorder and saw this common dieting myth was inaccurate.  Another common dieting myth held by people is that they may not be losing weight because they are in the "starvation mode" from eating too few calories. And, in response to the intake of this low calorie level, their body has gone into "starvation mode" and slowed down their metabolism and is holding on to the weight. The usual recommendation to get out of starvation mode and allow the body to lose more weight, is to consume more calories. Eat more calories, to lose more weight.

Really?

Well, for anyone struggling to lose weight, this may sound sensible, but as you will see, it, like most other dieting myths, it is inaccurate. A few things to consider before we get to the "starvation mode."

First, the human body, as is our world, is governed by the laws of physics. Body weight is a product of energy balance. We can not violate the laws of physics and thermodynamics. The energy we consume must go somewhere, and to maintain a certain level of weight, an equivalent amount of energy must be consumed and an equilibrium must be achieved.

Second, in regard to metabolism, about >70% of our base metabolism is driven by our brain and other vital organs and is not really effected by food consumption as I discussed in the metabolism blog. We have little impact on this basal metabolic rate.

Third, most attempts to accurately track food consumption under report (intentionally and/or not intentionally) by about 30% and attempts to track exercise and activity levels over report by up to 50%. Even professionals can be as much as 30% off or more. This is usually part of the problem. Fat people are not accurately able to determine their caloric intake and output.

Now, in regard to the "starvation" mode, someone who has extra body weight and body fat is not in any "starvation mode" where they need to 'kick start" their metabolism by eating more calories. You can not "eat more" calories to force your body to "lose weight".

In regard to metabolism, if you are overweight/overfat, you can not cause your metabolism to decrease below a level needed to lose weight while you have extra weight/fat on you, and you can not "lose more weight by eating more calories/food." This is a misunderstanding of the principles of metabolism that does not apply to overweight people trying to lose weight.

Let's say we look at someone who says they are only eating only 800 calories and not losing weight. A well meaning and good intentioned friend (or professional) has told them they are in starvation mode and in order to lose weight and/or kick-start their metabolism, they need to eat more. But, what if instead of eating more, what do you think would happen if instead they just stopped eating altogether? Would they go further into starvation mode and continue to stay at the same weight or maybe even "gain" weight?

Clearly, they would lose more weight if they stopped eating altogether.

We all know (especially those who are familiar with fasting) that if you were to stop eating completely and just live on pure water, you would start to lose weight almost instantly and would continue to do so.

But according to this theory of the "starvation mode," if you were really in it and you fasted, by its own rational you would lose less weight ... if any at all, not more. We know this is not accurate.

So, where did this myth come from?

There is a true phenomenon known as the starvation response and it is well documented in the Minnesota Starvation experiments and the Hunger Fasts that have been studied. However, it only happens in humans when they lose enough body fat that they fall below the level of essential fat. In a man, this would be below around 5% fat and in women just above that, about 10%.

Most humans will look like holocaust survivors at that time. Here is a picture of some of the subjects from the famous Minnesota Starvation experiments from the 1940s.

Even at this point, after months of a low calorie diet with heavy exercise, they were not yet in the so-called "starvation mode" where they experienced significant metabolic changes. If you have more weight/fat on you than them, then neither are you

In addition, when this point is truly reached, the body does make several metabolic shifts to preserve itself, and if it is not fed more calories, can cease to exist. It is a matter of life and death. Hence the name.

This is not the same thing that happens when someone who is overweight and has a high percentage of body fat, is not losing weight. Usually this is due to an inaccurate assessment of their energy balance.

Now, it is possible that a medical condition, like hypothyroid could contribute to a slowed metabolism. However, if someone was to have a thyroid problem, it can be diagnosed and treated. But, then we are right back to my points above and dealing with an energy balance issue.

So, if you are overweight and/or overfat and not losing weight, the most important thing to do is re-evaluate your energy balance. And the best way to do this is to focus on foods that are low in calorie density (and high in nutrient density) and maintain a healthy level of activity.

We now have enormous access to miscellaneous information via the internet. This means that a relatively intelligent, ordinary person, with a bit of formal education (such as myself), can be exposed to a myriad of possibilities…   together with little or no personal ability to determine the accuracy of the information provided.

Online time exposes us to ideas that are relatively new to us, and leads us to discover data and publications… including books and videos … that would have been otherwise unavailable to us.
Such exposure and discoveries make me think about things in ways I’ve not previously considered.  There are many great Theories in the world which modern Societies in general consider to be true…but .. chances are, some of them probably are not.

Along with many other people living in the “civilized” societies of the present, I am interested in my own eating and digestive process. Yes, eating is necessary for sustaining life, but I want to know more about how I can enjoy food  without getting fat.  In a way, eating is like sex. If there was no enjoyment in the process, people would be doing a whole lot less of it.

  So, what if the details we THINK we know about Food and the Digestive system are inaccurate?

I find it interesting to consider the possibility that much of the knowledge which we take for absolute truth about diet and nutritional information (which is often referred to as “conventional wisdom”), might be WACKED. When I say “wacked”, I mean “out of order, crazy, not in proper condition, screwed up, incorrect, so messed up it could be broken.”

What if?  

What if the state of our current knowledge regarding nutrition and the body is similar to that previous accepted Truth = “the world is flat”? Societies of the past functioned for long periods of history with what we consider now to be only minimal knowledge. Back in time, people did a great deal of traveling before they discovered that “the world is round”. We now tend to think of them as ignorant, but they were as knowledgeable and forward thinking as was possible at the time. People in the future might consider those of us who live here in the present, to be ignorant and backward.

   I recently read the following about how “calories” were discovered:

Up until March 16, 1896 at 10:30 am, food was just that – something we ate to stave off hunger and to grow. Food was nourishment and a source of “protein” (back then this meant even rice, potatoes and wheat), typically, about 12-15% protein was recommended. All foods were assessed for “protein.” There was “cheap protein” and “expensive protein,” but people didn’t equate meat with protein any more than gluten in wheat. It was a time of affordable nourishment as a priority. People were starving.

On that day in March, Wilbur O. Atwater began his now famous calorimetry experiments and fundamentally changed how we look at food forever. After locking a Dr. Olin Freeman Tower up in a small chamber for 5 days Atwater took measurements of Dr. Tower’s metabolism. Four days earlier Dr. Tower began eating a fixed “breakfast, dinner, and supper” and continued throughout the 5 days. He exited on March 21 having gained 2 lbs.

Atwater’s measurements included both the change in temperature and the oxygen consumed/carbon dioxide produced. For the first time – food, mostly meals, had a number.

They went on to perform many experiments on how the body digests and absorbs the energy and then assigned “caloric content” of these foods based on experimentally measured averages. Remember, we didn’t know about vitamins and minerals yet – that begins 30 years later. Atwater was simply ascribing a caloric content to protein, carbohydrate, fat and alcohol. The question answered: How did the body react to food when input, waste, heat and composition were precisely measured? Did the laws of thermodynamics apply to people and food?

Eat, swallow, and poop. Now, we have a quantification of energy.

Atwater changed everything we knew about food. He made some groups angry, like the Woman’s Christian Temperance Union, for suggesting alcohol actually had calories, but he defined the notion of digestibility of food based on protein, carbohydrate fat, and alcohol energy content. He had good goals and unbelievable attention to detail, but he warned that these numbers shouldn’t be used too much outside the bounds of the food combinations that were studied.

On the not-so-helpful side of things, Atwater inadvertently launched the now common “macronutrient wars.” With this new data, the beef and wheat industry could go head-to-head on “affordable protein.” These battles have raged on for a century and soon food was being ubiquitously labeled with “proteins, carbs and fats” and today, diet dogma abounds on the mythical ratios for health.

When Atwater began these investigations, we were still trying to validate Lavoisier’s work a century earlier that equated the chemistry of a burning candle and the Human body’s digestion of food.

Atwater wasn’t a fan of bread and simple sugars and advocated that more legumes and vegetables be incorporated into the diet. People thought of food very differently then – remember, nourishment. After Atwater died, we learned so much more about the role of vitamins and minerals, but at that time it was much more simple and in some ways, easier to make decisions. When the first food pamphlet (after his death) was published in 1916 – Food For Young Children by Caroline L. Hunt, I’m sure it wouldn’t have met his approval had he been alive. In it, you can see the beginnings of what would be a century dominated by special interest and food political agendas.

In the little over a century between 1796 and 1900 Lavosier and Atwater made HUGE progress on energy and in the last century we’ve made progress on vitamins and minerals.

We have taken Wilbur Olin Atwater’s life work and reduced it to … pervasive, unintelligible, and misguided recommendations for people.

The key to weight loss AND health is to start talking about food, and not label it with macronutrient names based on a fictional notion that the most significant factor of a food is the majority of the macronutrient present within it.

 The above-article comes from the personal blog of Ray Cronis, which is known as Thermogenex, located at www.hypothermics.com. It says that

Ray Cronis studied chemistry in undergraduate and graduate school and began his career as a Material Scientist at NASA's Marshall Space Flight Center. During his 15 years at NASA, he worked on a microgravity material science, physical & analytical chemistry, and space station environmental control an life support systems. Ray co-founded Zero Gravity Corporation with Peter Diamandis and Byron Lichtenberg - creating the world's first private parabolic flight operation. He is not a medical doctor, but is informally currently exploring the issue of weight loss by way of basic thermodynamic principles.

As part of my Dieting Hobby, I often consider things such as these,  simply because I find them interesting and/or inspiring.  I don’t feel it necessary to make a personal decision as to whether the ideas are truly “correct” or “incorrect”. Here at DietHobby my philosophy is: 
 Take what you like and leave the rest. 

Review of the 5 Bite Diet

The thin, large-print, paperback book “Why Weight Around” (2007) by Alwin Lewis, M.D., encourages readers to follow the five-bite diet for weight-loss. This is a self-published book through Lulu "vanity" press and it retails for around $25.

Dr Lewis recommends the 5 Bite approach to eating:

• Drink as much as you want as long as the drinks are free of calories.
• Skip breakfast
• Have 5 bites of any food for lunch.
• Have 5 bites of any food for dinner.
• Eat at least one bite of protein each day.
• Take a multi-vitamin supplement every day

Dr. Lewis assures the reader that after three days on this diet, that you will stop feeling hungry because your body will learn to feel full on this smaller amount of food. This is commonly known to be a valid statement, as hunger ordinarily leaves one’s body after approximately 3 days of starvation such as during a water fast.  He says the the body continually recycles amino acids so very little daily protein is actually necessary when on a weight-loss program.

The five-bite diet involves voluntarily eating the way people are forced to eat after a gastric bypass, in order to give a dieter the benefits of stomach stapling without the surgery. As with many diet plans, the principle of the five-bite diet is to exercise portion control in order to limit your calorie intake. The program allows you to choose to eat any food you want, which can help prevent the feelings of deprivation that often lead people to quit their diets. The five-bite diet is not designed to be a permanent plan. Once you've reached your weight goal, you're advised to resume your normal eating habits.

Dr. Lewis says the volume of 5 bites is about the same as a regular size Snickers candy bar, and recommends that people on the diet eat two Snickers bars a day in order to familiarize themselves with how much 5 bites is.

Dr. Lewis, …just like almost all diet book authors … claims to have successfully followed his diet himself, and at 6 ft tall, he says that he lost from his high of around 190 lbs down to 137 lbs. He recommends that, for good health and a more attractive appearance, everyone should achieve an 18.5 BMI, which is at the bottom border between underweight and normal weight.

Dr. Lewis practices Internal medicine in Burbank, California where he apparently treats obese, overweight, and normal weight patients who have a BMI above 18.5, by putting them on the 5 bite diet. His website, theslimmingstation.com offers an online membership, for $50 per year, but at times this membership fee is $50 per month. It also offers 3 months of weekly one-on-one telephone coaching with Dr. Lewis for a $2,000 fee.

As part of my dieting hobby, I have experimented with the 5 bite diet. Twenty years ago, after my own gastric bypass, I personally experienced what post-gastric-bypass surgery eating is like, and was interested in running a comparison between that experience and the 5 bite diet.

My experimentation with the 5 bite diet occurred while my weight was in the middle of the normal weight BMI range. I successfully completed two weeks of 5 bite diet, and left it in the third week. The first week my weight dropped 7 pounds. While continuing to successfully follow the 5 bite diet rules, during the second week on the 5 bite diet, my body re-gained 5 of those pounds. I left the diet during the my third week, and upon returning to my normal 1,000 calorie diet, the remaining 2 pounds immediately returned, giving me a zero net loss. During a three year period, I repeated this experiment on several occasions, and each time I received similar personal results.

The calories in two 2 oz Snickers candy bars is a total of about 550 calories.   Therefore successfully following the diet would cause weight loss for almost everyone, especially if that person is obese. Normally, I maintain my current weight on about a 1,000 calorie daily average. My personal results were due to my normal-weight as a short, inactive, reduced-obese female over 60 years of age, with a very low calorie burn, and probably... during the diet, my body's metabolism shifted downward to compensate for the very-low-calorie-intake.  if I had chosen to follow the 5 Bite diet for a longer period, over time, it might have caused a net fat-loss. However, the 5 Bite Diet hasn't provided enough appeal to me personally to motivate me to follow through with testing that hypothesis.

My first experiment with this diet was several years ago, and as a part of that process, I purchased a year’s online membership for $50, and for a time, actively posted on Dr. Lewis’ site. As part of that membership I participated in several of the weekly chat sessions with Dr. Lewis himself.   Dr. Lewis was very committed to the 5-bite diet and enthusiasttic. He appeared, however, to be rather insensitive, very egocentric, and sometimes quite rude. When people achieved only modest weight-loss results, he was prone to imply they were lying about their compliance. He ignored some very basic dieting realities, and while "coaching" members, he was prone to state his opinion as fact, and make grandiose claims which (similar to marketing puffery) were backed up by little or no verifiable evidence.

My above-stated opinion was formed due to what I witnessed during my online participation,  As one personal example: I took exception to Dr. Lewis' blanket statements about HOW FAST EVERYONE ALWAYS loses weight after a Gastric Bypass, and advised him that this was not my own experience nor the experiences of many other women that I have personally witnessed. 

To explain my objection to his claims of fast weight-loss for EVERYONE, I told Dr. Lewis that after reviewing my own detailed  records (which I kept current during the first year after my own Gastric  Bypass), my personal weight loss during the first year after surgery ... while eating only about 500 calories per day ... averaged around 2 pounds per week... From 271 lbs down to a low of 159 (which for me was still "obese", because that number is 6 pounds above the bottom BMI border of my "Obese"  weight-range).  Providing him with this information and detailed records, did not cause any adjustment or alteration in his position, and in fact Dr. Lewis indicated to me that he believed that my statements were either inaccurate or less than truthful.

For those here who are interested, I'll add that following the 1st year after my Gastric Bypass, I had an almost immediate  regain into the mid 160s, as my ability to eat more calories increased. After about three years, while eating approximately an average of not more than 1,500 to 1,600 calories a day ... together with a great deal of active dieting to maintain my weight-loss,...  my weight crept back up into the 190s.

I believe that every diet works for someone. The 5-bite diet is an interesting concept, and I can see how it could be an effective weight-loss tactic for an obese person with an extremely busy schedule, especially if that person has latent anorexic tendencies and lacks a genuine interest in food.  At this point, I am not totally opposed to the 5-Bite Diet. It has many things which appeal to me, and there may be a future time when I will choose to try it again.

Below are two videos about the 5 Bite Diet.

The FIRST video is an interesting and positive interview of Dr. Lewis.

The SECOND video is an rather amusing negative diet review.
