How people can gain weight by intestinal starvation

This website is based on my personal experience of losing weight down to the thirty-kilogram range when I got into college. In the beginning, I was eating as much as possible focusing on carbohydrates and high-calorie foods because I thought I had to gain weight, but I could not gain any weight. When I almost gave up, I thought that if the food wasn’t digested, it was meaningless, so I tried not to eat fat and fiber and ate moderate amounts of easily digestible carbohydrates (starch) and protein, etc. without overdoing it.

One day, I gained more than five kilos over the course a couple of days and something similar happened a few times in a similar situation. I was very thin, so I found out exactly what had caused the weight gain. There were also other people who gained weight rapidly as I did under similar situations. They didn’t eat much.

Through these experiences, I questioned the common belief that the causes of weight gain are obviously excessive caloric intake and/or lack of exercise.

In Japan, as there is a saying "a big eater who stays thin," some people eat a lot but never gain weight. On the contrary, there are others who do not eat much but are overweight. Moreover, I saw some people who gained weight little by little after they started dieting to lose weight. 

Generally, such cases are explained using metabolism as an excuse or “it’s how they were born,” which I think is vague. However, I thought that all such contradictions could be explained based on my experiences, and then I started to formulate theory as a hypothesis.
     

Currently, overeating and lack of exercise are considered the causes of obesity and metabolic syndrome, but In fact, I’ve heard that few intervention studies have been done to prove whether people really gain weight if they continue to consume a lot of calories more than their bodies need. Many experts simply believe that it should be in terms of the "calories in/out" theory. 

According to Dr. Jason Fung, the author of "The Obesity Code," there is only one study conducted by Dr. Ethan Sims in the 1960’s. It has been shown that some people gained little weight even with a large increase in caloric intake, and that even those who gained weight, stopped at a certain rate and eventually went back to their original weight.[1]

In addition, recent studies as well as the experience of dieters, have shown that most people who were on a calorie-restricted diet regained the weight they had lost in just a few days or, at the most, several months.

That being said, some experts have pointed out that each person has a stable weight based on their ability to maintain homeostasis. I have referred to that weight as "base weight"(*1) ever since I started blogging in 2014, and that is the basic idea throughout this website.

(*1)Some experts call this “set weight.”

1. The amount of calories ingested or burned is not the fundamental reason that some people become obese and others do not. I believe that increased base weight is the primary problem of obesity, and base weight goes up by the induction of intestinal starvation.

2. “Intestinal starvation" refers to a condition in which all food is digested in the entire intestines (or it might be the small intestine only), caused by a repetitive cycle of "eating" and "not eating (being hungry)," which is a message to the body that “there is no food.”

3. Refined carbohydrates, easily digestible protein, fast foods, and processed foods, etc. tend to cause intestinal starvation; conversely, fiber, fat, and less processed foods, etc. tend to prevent this.
I believe that the recent increase in obesity all over the world has been attributed to unbalanced diets leaning toward carbohydrates and irregular lifestyles.

4. For example, consider these two types: "people who want to gain weight, but can't" often eat high-calorie foods to gain weight, whereas "people who are overweight " often eat less to lose weight. However, on a caloric basis, it is my belief that they are theoretically doing the opposite action with regards to weight loss and weight gain.

5. Exercise is a must for being healthy, but not for losing weight. You can lose weight by changing your eating habits even with an absence of exercise.

My main purpose for running this website is to let many people worldwide know my thoughts, but I don't want to eventually stop with just an "interesting idea." Ultimately, I’m hoping to somehow prove that "intestinal starvation makes people gain weight."

June 2023: I have begun to send out offers to obesity research institutes and universities around the world, including Japan.

Maybe I should just leave this to the doctors and researchers. But I felt strongly that I had to write about this because I knew I was the only one that could write about this theory.

In fact, I used to lose confidence, but then I came across a book "Why We Get Fat" by Gary Taubes and it gave me courage.
    

"The history of science suggests another interpretation: if people have been thinking about this idea for more than a century and trying to test it for decades and they still can't generate compelling evidence that it's true, it's probably not. We can't say it's not with absolute certainty, because science doesn't work that way. But we can say that there's now an exceedingly good chance it's simply wrong, one of the many seemingly reasonable ideas in the history of science that never panned out. And if reducing calories-in doesn't make us lose weight, and if increasing calories-out doesn't even prevent us from gaining it, maybe we should rethink the whole thing and find out what does."[2]
