Why Are Fat People Hungry?
- POSTED ON: Aug 06, 2015

The video below is an easy way to learn more about the issue of insulin resistance or high insulin levels. The first three-fourths of the video contains information on scientific research with some interesting charts and graphs.

When considering insulin levels, it is important to remember that a high insulin level can exist within a body even without a high blood glucose level.

Below is a transcript of the final one-fourth of the 32 minute video which encapsulates “Butter Bob’s” own personal viewpoint of the solution to the fat dilemma.

“Fat, your body fat is there around your middle, because your body thinks it is in a fed state all the time. And if your insulin pattern is like these we’ve looked at, you probably are in that fed state most of the hours of the day, everyday.

There’s only one way of getting this fat off. If the body believes that fat needs to be stored and held onto because there’s plenty of food, and it does believe this if insulin remains high, then it is waiting for something.

What is it waiting for?

It’s waiting for the signal that food is not available, that’s what it’s waiting for.

What is that signal? Low insulin levels is that signal.

As soon as you give it that signal, that food is not available, it will start releasing the fat. It just will, the work of George Cahill has shown us that.

That’s why so many different diets work, any diet that restricts your calories, makes your calories really low, therefore lowing your insulin levels, is going to send that signal, because it lowers your insulin level and this sends the signal to release the fat.

The problem is sustainability, in a world where food is everywhere, it’s hard to sustain a low calorie diet. Is it impossible? No. People have done it, many people have done it.

A Low Carb – High Fat diet (the diet I used to lose 150 pounds) is a diet hack, it’s a trick. It’s an imitation of fasting, an imitation of starvation. Starvation itself is a situation where circulating fat is high and insulin is low, a LCHF diet is also a situation where circulating fat is high and insulin is low.

So what’s the trick? We are restricting carbs, and we’re keeping our protein fairly low, not low enough to make us sick, but low, because protein has an effect on insulin that is about half that of carbs. That’s right, when you eat protein, especially some low fat lean protein, you are actually raising your insulin about half as much as eating carbohydrates.

We feed our body fat for a reason, firstly, so we can have something to eat, which makes this diet sustainable. You know trying to go without food long enough to make a difference is extremely hard to do. But this way of eating allows you to eat.

This sustainable fat diet allows us to eat, which makes the diet easy and the high fat part of this diet sends the signal to the body that we’re not eating, you see it’s a trick, because if the body has a lot of fat circulating around inside, fat from the diet, the body thinks it’s in starvation mode already, because if it was actually going without food, the body itself would be releasing fat.

So if we eat fat, when we do eat, it’s sending the SAME signal that the body would get if it was actually going with...

Does Fasting Make You Fat?

Does Fasting make you fat?
            by Brad Pilon

If I remember correctly, the FTC views the use of animal research in supplement advertising to be one of the most heinous advertising infractions, right up there with Photoshopped before and after photos.


Because they believed that due to the lack of transferability of animal research to humans, doing so would be intentionally misleading the customer as to the potential benefits of said supplement.

Even the most ‘fly-by-night’ ethically-devoid supplement companies do not use animal trials in their marketing for this reason.

Keep this in mind when you see journalists and bloggers reporting on the latest mouse research, using it to create clickbait style articles about human diet, nutrition and weight loss.

Alright, now that I’ve said that, lets get to that article that appeared on Yahoo suggesting that skipping meals will actually make you fatter.

It was an animal study, using mice.

We know that mice are extremely sensitive to fluctuations in both body weight and meal patterns. They are very small animals, and without getting too technical I’ll just say it’s well known in the scientific community that many parts of metabolism scale with size.

For 5 days the mice in the diet group were given half the amount of food as the control mice, and all of the food was provided in one meal per day (that’s why it’s being referred to as a ‘fasting study’).

After 5 days of dieting the mice were allowed to gorge for 13 days, they were given an amount of food that was the same or more as the control mice, and were still only eating it all in one meal.

So what happened?

The control mice continue to grow normally, and their weight increased throughout the study, but the fasting diet-restricted mice lost almost 20% of their body weight in the first 5 days of the study. (This should be your first hint that mice are different than humans. If you and I eat 50% of our daily intake for 5 days we’re not going to lose 20% of our body weight – heck, we could do this for a month and we’re probably not losing 20% of our body weight.)

Then, the fasted mice were fed 98-122% of the amount of food as the growing control mice, so the fasted mice started to grow… and they grew quickly. If you think about it, they were getting fed the same amount of food (or more) as the mice that were 30% heavier then them… so rapid weight gain (and fat gain) make sense.

So end result? Mice who rapidly lost 20% of their body weight and then regained most of that weight by overeating ended up with larger fat cells then the control mice. I’m not sure why this is surprising.

They also had worse measurements of a bunch of health markers… again not surprising.

I’m not sure how much the eating cycle mattered here. Again, as I stated earlier, mice are really sensitive to eating patterns so it probably did play some sort of role, but rapid weight loss then overfeeding causing increased fat stores and messed up glucose control isn’t surprising.

The Real Deal on Maintenance After a Large Weight-Loss
- POSTED ON: Apr 12, 2015

My own lifetime of observation and personal experience tells me that the following article is “The Real Deal” on the issue of maintenance of a large weight-loss - including long-term maintenance. 

By “The Real Deal”,  I mean genuine, authentic, true, exact, trustworthy, and clear.

For those who don’t know, for the past 10+ years I’ve been successfully struggling to maintain my 5 ft 0 inch elderly body at a “normal” BMI after years of “morbid obesity”, through a great many different dieting methods.  More information is in  ABOUT ME as well as in many articles about my Status in the ARCHIVES.  I will be writing more about my personal weight and calorie details at the bottom of the following article:

You Should Never Diet Again:
The Science and Genetics of Weight Loss

To maintain a new weight,
you have to fight evolution.
You have to fight biology.
And you have to fight your brain

         by Dr. Traci Mann  .. Excerpted from "Secrets From the Eating Lab". (2015)

I’ve given you the bad news: diets fail in the long run. Now, let’s try to understand why.

In social psychology we often say that if you find that most people behave in the same way, then the explanation for their behavior has very little to do with the kind of people they are. It has to do with the circumstances in which they find themselves. For example, most students in class raise their hands and wait quietly to be called on before speaking. It’s not that they are all timid or overly polite types of people. It’s that the classroom setting is sufficiently powerful that without really thinking about it, nearly everyone ends up following the same unwritten rules. When we think about people who regain weight after dieting, it’s a similar principle. It’s not that they have a weak will or lack discipline, or that they didn’t want it enough, or didn’t care. It’s about the circumstances in which they find themselves, and the automatic behavior that is provoked by those settings. In other words: if you have trouble keeping weight off, it is not a character flaw.

When it comes to keeping weight off, a combination of circumstances conspires against you. Each one on its own makes it difficult, but put them together and you are no longer in a fair fight. One circumstance that makes things hard is our environment of near-constant temptation. Two others are biology and psychology. I realize it may seem odd to you that I am calling these things “circumstances,” but, like a classroom setting and the behavior it produces, we need to acknowledge the context in which...

Biological Adaptations that Promote Weight Regain
- POSTED ON: Mar 04, 2015

There is a “widespread misimpression” that weight-loss and maintenance for bodies which have become and stayed obese for more than a couple of years, is essentially the same as that for bodies which always have been:

  • normal weight (BMI between 18.5-24.9);
  • overweight (BMI between 25-29.9); or
  • have spent a brief time within Grade 1 obesity (BMI between 30-34.9).

In a commentary published February 26, 2015 in the journal Lancet Diabetes and Endocrinology, four weight-loss specialists set out to correct what they view as the widespread misimpression that people who have become and stayed obese for more than a couple of years can, by diet and exercise alone, return to a normal, healthy weight and stay that way.

"Once obesity is established, however, body weight seems to become biologically 'stamped in' and defended," wrote Mt. Sinai Hospital weight management expert Christopher N. Ochner and colleagues from the medical faculties of the University of Colorado, Northwestern University and the University of Pennsylvania.  

“Few individuals ever truly recover from obesity.” Those that do "still have 'obesity in remission,' and are biologically very different from individuals of the same age, sex and body weight who never had obesity." They are constantly at war with their bodies' efforts to return to their highest sustained weight.

That February 2015 commentary together with the August 2013 research article below explain many of the things that I have experienced personally, and that I have personally observed.

An additional article dealing with this issue is located HERE in the DietHobby Archives.
