First of all, it's important to know what the job of nutritionist really is .

A nutritionist is a real doctor who deals with nutrition-related diseases.
He must therefore know precisely the food values , their composition , their effects on the body and must be able to propose a nutritional program adapted to the needs of patients. Generally, he specializes after his first 6 years of medical school. This nutritionist category includes real health professionals.

But with the cult of thinness increasingly present in our society, we all seek to lose weight (even when it is not really necessary). And when one can not afford a personal follow-up with a nutritionist doctor, many refer to "old" fat as Sonia Dubois or Karl Lagerferld who managed to lose weight and who resell their dietary advice through books.
Keep in mind that these personalities who want to share their experience with the general public have absolutely no special skills in nutrition.

Finally, let us add that very often, advertisers themselves put on the white coat and position themselves as a nutritionist to sell lightened yogurts or stage Doctor X or Y disclosing nutritional advice ....

So a question arises: who to believe among this avalanche of conflicting advice? Who to refer to ? Is there an absolute truth about nutrition?
What must be remembered is that:

- Each individual is different . There is no ideal diet rule. Obviously, he maintains a balanced diet, but all this is part of a whole food behavior and not close to detail ...

- From this first observation follows the second. Since we are all different in the face of nutrition and nutritionism is not a science that could be described as " exact ", no absolute truth can be established in this area.

- Finally, and this is the main idea that must be remembered: there is no miracle diet. The secret of weight loss? You have to consume fewer calories than you spend, eat balance and practice regular physical activity.
