Prologue

 "The experts who say that we get fat because we overeat or we get fat as a  result of overeating - the vast majority  - are making the kind of mistake that would (or at least should) earn a failing grade in a high-school science class.
They're taking a law of nature that says absolutely nothing about why we get fat and a phenomenon that has to happen if we do get fat - overeating - and assuming these say all that needs to be said." (P.76)

This is the foundation I started writing my blog on. I’m assured that there are at least a few researchers in the world who think in the same way as I do.

Even if someone insisted that “the Earth is going around the Sun” in 16th or 17th century where geocentric theory was the common sense, no one would have believed him.  Many should have argued that “if the Earth is going around the Sun, our heads should go around too”. However, now, it’s the common sense that the Earth is going around the Sun.

In the same way, many might not believe me when I say “eating too much or too many calories are not the direct cause”. However, I believe it’s the truth.

1.People don’t “gain weight” because of eating too much

It is said that “eating too much and not enough exercise are the cause of gaining weight” but here is an interesting experiment related to it.

(Citation from “Why We Get Fat?” by Gary Taubes)

 "In the early 1970s, a young researcher at the University of Massachusetts named George Wade set out to study the relationship between sex hormones, weight, and appetite by removing the ovaries from rats (females,obviously) and then monitoring their subsequent weight and behavior. The effects of the surgery were suitably dramatic: the rats would begin to eat voraciously and quickly become obese.

The rat eats too much, the excess calories find their way to the fat tissue, and the animal becomes obese. This would confirm our preconception that overeating is responsible for obesity in humans as well.

But Wade did a revealing second experiment, removing the ovaries from the rats and putting them on a strict postsurgical diet. The rats, postsurgery, were only allowed the same amount of food they would have eaten had they never had the surgery.

What happened is not what you'd probably think. The rats got just as fat, just as quickly. But these rats were now completely sedentary. They moved only when movement was required to get food.

The way Wade explained it to me, the animal doesn't get fat because it overeats, it overeats because it's getting fat. The cause and effect are reversed. (PP.89-90)
*snip*
The evidence that fat tissue is carefully regulated, not just a garbage can where we dump whatever calories we don't burn, is incontrovertible. (P.94)
Those who get fat do so because of the way their fat happens to be regulated and that a conspicuous consequence of this regulation is to cause the eating behavior (gluttony) and the physical inactivity (sloth) that we so readily assume are the actual causes." (P.93)

<1970s>
  Words of Bruce Birstrian who conducted a treatment of a low calorie diet (600kcal/day) to thousands of obesity patients in Harvard University of Medicine.

"Undereating isn't a treatment or cure for obesity; it's a way of temporarily reducing the most obvious symptom. And if undereating isn't a treatment or a cure , this certainly suggests that overeating is not a cause." (P.39)

(citation from "Why We Get Fat?" by Gary Taubes )

Though you might think the rats’ story is different from my story, I want to tell of my experience of “gaining weight not because of eating more”.

When I was very thin about 35kg, I couldn’t eat anything since my stomach was heavy . Especially, food with oil was the worst.  I tried hard in order to gain weight but nothing was added to my body.

One day, I realized that I can gain weight by creating “intestinal starvation” so I ate mainly easy-to-digest carbohydrate and tried to make my stomach hungry (by not taking fiber or fat). I gradually gained weight in this way. And when I weighed about 50kg, I had more muscles and no discomfort in stomach. I was able to eat more than before.

Those who didn’t know my experience told me “you’re gaining weight because you’re eating more” but that wasn’t true. The order was “After my body became able to gain weight, I gained weight by eating and got more muscle and appetite. As a result, I was able to eat more than before”. So, the reality was completely the other way.

▽Maybe it’s easier for you to imagine with an extreme example.
If there was a man 3 meters tall and weighs 250kg. If he eats 5 times more than us, you won’t think “he became big because he eats a lot” but rather “he can eat a lot because he is big”.

2.Example of not enough exercise after getting fat

 "Some people find it hard to get their head round the fact that aerobic exercise is not particularly effective for weight loss, even when faced with all the facts.

One reason for this is our experience of seeing physically fit and active individuals who are clearly lean. Look at any elite long-distance runner or Tour de France cyclist and you're probably getting a glimpse of what it's like to have a single-digit body fat percentage. The automatic thought process is that exercise causes leanness.

However, could it that individuals who are naturally lean are simply more likely to end up as elite long-distance runners or cyclists? In other words, might their natural leanness cause certain people to be more active, rather than the other way round?

There's actually some evidence for this. In one piece of research, the relationship between physical activity and body fatness in children over a 3-year period was assessed. It was found that the more sedentary children were, the more fat they carried.

This is all to be expected, but because the study was conducted over a prolonged period the researchers were able to gauge whether sedentary behaviour preceded weight gain.

Actually, it did not. In reality, children accumulated fat first, and then became more sedentary. The authors noted that this finding 'may explain why attempts to tackle childhood obesity by promoting PA [physical activity] have been largely unsuccessful'. "(PP.223-224)

I agree with this opinion but I want to add my opinion.
I think it’s reasonable to think those who are thin aim to be a marathon athletes or soccer players. At least, they know that they won’t gain weight by eating more. They take 3 well-balanced meals/day and that prevents “intestinal starvation” and keeps their current condition (while getting a little more muscle).
That is to say, it’s not that they are consuming calories of what they eat more by doing sports. Taking 3 well-balanced meals make it unnecessary to stock body fat.

On the other hand, those who stay at home a lot playing TV games or reading books tend to eat less. Sometimes, it’s only hamburger, only french fries or noodles.

Since they don’t do exercise, they don’t pay attention to nutrition. Such situation can cause them to be easier to get fat (intestinal starvation mechanism).

It’s not because they take more calories nor consume less calories. For those who are lazy it might be easier to gain weight, but not enough exercise or laziness won’t directly make people fat. The cause is something else.
