It's the brain that decides our weight!

Diets are useless, it's not a scoop. The American neurobiologist Sandra Aamodt goes even further in a book entitled "Why diets make you fat" (not yet translated into French). After spending a year without any dieting and engaging in daily physical activity, she found that her weight remained stable. This uselessness of the organized food deprivation pushed her to seek, in the scientific literature, on the side of the brain.



It is he who determines our ideal weight, whether we like it or not. Basically, the brain establishes a weight range of about 5 kilograms. More precisely, the hypothalamus. It is this small gland that analyzes nutritional information (lipid stocks, blood sugar, energy expended by the body, etc.) and gives the appropriate responses by triggering, or not, the feeling of hunger.

Athletes are at the bottom of the fork and lazy rather at the top. The risk, in case of weight gain, is that the brain, faced with the fait accompli, does not consider this overweight has become the reference. For the organ conductor: "there is no reference weight, just a stable weight to defend". Hence the importance of not settling in the overweight and uselessness of regimes, doomed to failure.




Worse, the studies that the author has peeled show that, statistically, people who chain diets are more likely to become obese one day than others. One solution, she thinks: do a little exercise every day, and, more difficult, eat only what is necessary stopping when feeling satiety reached: "At first it takes a lot of 'attention and effort because we live in a society of food hypersollicitation and then we take the habit and things are done naturally.
