It is useless to try to become as thin as most Hollywood actresses, if nature has not foreseen this. Even the toughest diet will not allow you to move much away from your natural weight, says Dr. Gilles Hirsch of the University of New York.
The fact is that each person has a program of a certain weight. The organism seeks to support it by changing the intensity of metabolism. If a person has lost weight, calories start to burn more slowly, and if recovered - faster. So very soon the weight comes back to normal again.
But if you quickly began to recover, it is already about metabolic disorders or other serious problems.
