Outline
The Big picture of This Website
I 'd like to introduce the outline of this website to those who visit my website for the first time.
1. Two meanings to the phrase gaining weight
It is generally said that eating too much and taking in too many calories are the causes of gaining weight, but this theory has a major flaw.
In reality, there are two types of weight gain:
(1) you gain weight by eating a lot of calories.
(2) you get the body that becomes more likely to gain weight when you haven’t eaten (like the rebound effect after dieting).
The fundamental difference between people who are obese and people who eat a lot but are thin, and also the global obesity issue, is rather a matter of (2).

To explain this, I have introduced the term “base weight,” as I believe there is basically a function of homeostasis in our body.
The fact that we gain weight when we take in too many calories is part (B) of the diagram, while the fact that we become fatter when we haven’t eaten indicates that the base weight value itself increases, as shown in (A) of the diagram.
2. why people get fat
I know there are many theories, but let's assume that human genes were created tens of thousands of years ago. Considering the original functions of the human body, can’t we think that body fat is a storage mechanism for starvation (when you cannot eat)?

Even the muscles and the brain do not decrease with use. Muscle strength is increased by putting a load on muscles through exercise. Studying increases our ability to think and remember.
In other words, from the perspective of the mechanism of the human body, the reality is the opposite of the theory that “we gain weight because we eat too much or take in too many calories.”
The idea of storing fat in the body as a reserve for starvation is something that every researcher thinks of, at least once. However, it is said that this theory is an idea denied by many researchers in history. This is because many obese people often eat more and African refugees are thin and malnourished. Some may say, “If starvation makes us fat, African refugees should be obese...”
3. How do our bodies perceive starvation?
Now, the question is: based on what does our body determine that there is no food?
From my experience when I was so thin, it is not that you are starving because of poor nutrition. The state of all food digested is what our body perceives as "no food."
On the other hand, when fiber, fats, oils, and other undigested materials remain in the intestines, our body recognizes that “there is still food” (I believe it is the entire intestines or small intestine that recognizes all of this).
I call this state of complete food digestion "intestinal starvation."
Make no mistake, this is not the same as mere hunger. In most cases, even when you don’t eat anything for twelve hours, a few undigested foods such as fat or fiber remain in your intestines, because our intestines are as long as seven to nine meters (the small intestine is about six meters), but if you keep eating an unbalanced diet that leans toward carbs and some meat/fish such as fast food, it’s possible that you can digest all the food in your intestines even in half a day.


That’s why our modern diet, which came from the U.S. and Europe, is more likely to induce intestinal starvation, while the traditional diet of the past is said to be less likely to make you fat.
4. People who want to lose weight and those who want to gain weight are doing the opposite of what they have to
Food sources that make it easier to induce intestinal starvation are our current foods such as refined carbohydrates, easy-to-digest protein (meat, fish, etc.) and processed foods.

This is because carbohydrates, when taken with water, expand in the stomach, diluting the concentration of the food eaten and speeding up digestion.
In contrast, eating a variety of foods such as vegetables, dairy, seaweed and dietary fat, prevents this. That's why people who eat a balanced diet regularly tend not to gain weight.

▽Thinking about dieting based on caloric intake, people who want to lose weight tend to avoid calorie-dense foods such as oily foods.
In addition, they try to skip meals, which results in an increase in base weight value and may lead to weight gain over the long haul.
Also, when some thin people want to gain weight, they try to eat high-calorie foods such as deep- fried foods. Besides, they often snack between meals without hesitation.
However, when thin people eat that way, as a result, some undigested food is always left in their intestines and base weight value does not increase.
In this case—theoretically—the overweight person and the thin person are both doing the opposite of what they hope to achieve, and both tend not to have good results.
5. Even if they eat the same way, there are people who gain weight and people who don’t
Of course, even if carbohydrates are likely to make you gain weight, it does not mean that everyone who eats a big bowl of rice, a big-sized burger, or instant noodles, will gain weight.

Some people gain weight even without eating many carbs vs others who never gain weight regardless of eating too many carbs.
I believe that there need to be at least four determining factors to cause intestinal starvation.

Three (+one) Factors to Accelerate “Intestinal Starvation”
▽ I used the word "relatively" to explain the reason that some people gain weight and others don't, even if they eat the same way.
For instance, if Mr. A, who weighs eighty kilograms, and Mr. B, who weighs forty-five kilograms and is thin, eat the exact same food at the same time every day, Mr. A tends to gain more weight than Mr. B. Assuming that Mr. A has stronger digestion, you can say that the person who can digest food faster “eats relatively less.”
On the other hand, people with weak digestion or gastroptosis tend to leave undigested food in their intestines through an entire day, making it difficult for them to gain weight, even if they eat the same way.

6. Why time and frequency of meals affect obesity
In Japan, it is said that a well-balanced breakfast is less likely to make you fat no matter how much you eat, while a late-night meal is more likely to make you fat, though there may be some influence from television, etc. It is also said that if you skip breakfast and have two meals a day, you are more likely to gain weight.


Of course, this is not true for everyone, but I can explain why this tendency appears with my intestinal starvation theory.
The food we eat is sent from the stomach to the small intestine and then to the rectum over a period of around ten hours. This means that when we eat and how many times we eat in a day, are also important factors.
If we think of the causes of obesity with daily caloric intake or carbohydrate intake, the timing and frequency of eating will not be important factors. Therefore, specialists try to explain it by metabolism and blood sugar levels. I believe these are extremely unnatural.
7. Cause and effect are reversed
Increasing the base weight value basically means “absolutely enhancing the ability to absorb.” Therefore, by increasing your base weight level and enlarging your body size, you are able to take in more protein and other nutrients as well as calories. Digestive enzymes and hormones are also made from protein, so it is no wonder that bigger and fatter people can digest the same food faster. As a result, these people tend to eat more because they get hungrier.

In short, the cause and effect are sometimes reversed: people don't get fat because they eat more, but because they are bigger and therefore inevitably eat more.
This leads to giving the wrong message to others, including obesity researchers.
8. Genetic factors
The biggest genetic factor I can think of is the digestive ability of each person. Of course, this can also change later in life, but people with a strong stomach that can digest food (especially fat) quickly will have a tendency to gain weight.

However, I am basically negative about the special gene (obesity gene) that causes obesity.
As I mentioned earlier in section four, the reason why some people gain weight despite reduced caloric intake is because the current calories-in/calories-out theory is obviously wrong.
Also, as mentioned in section five, the mechanism of intestinal starvation can explain why some people gain weight easily and others don’t, even though they eat the same.
How to prove my theory
If there are researchers who understand and agree with my idea, I think we can prove that people can gain more weight by inducing the intestinal starvation, even if they reduce their caloric intake and/or carbohydrate intake.
First, all you need to do is to gather the bare minimum of ten people who don’t gain weight and stay the same, even though they eat a lot. Monitor them for a few weeks. (However, it is difficult to get results if they have gastroptosis or weak digestion, like me).
Second, by eating the diet that I will specify for a certain period of time, (at least I believe that) fifty to seventy percent of the test subjects will gain weight dramatically and then basically maintain that weight.
I’m positive that if this experiment is repeated with the same person several times, it is possible, for instance, for a person who weighs seventy kilograms to weigh ninety kilograms, and eventually one-hundred-twenty kilograms or more.
