The results presented today are based on the analysis of questionnaires from 105,771 subjects, aged over 18 years.
Followed by many French, so-called “restrictive and marketed” diets, based on methods defined as “Dukan” or “Cohen” would be less well tolerated, more complicated and above all more frustrating than diets based on following nutritional recommendations.

Women start dieting earlier
Some 18,188 of these Nutrinauts claim to have followed at least weight loss diet in their life, including 28% of women who have even tried more than five diets in the past. Generally speaking, women start dieting earlier than men (36% between 15 and 25 years old, against 18% of men).
A multitude of restrictive diets
Of the participants who had at least one diet in their lifetime, 32% had tried a restrictive “marketed” type diet.Dukan“,” Cohen “, or”Chrononutrition“, 23% followed a restrictive homemade diet, 10% carried out a diet accompanied by individual coaching of the”Weight Watchers“and 35% simply followed the nutritional recommendations issued by the health authorities.
Diets less effective in the long term
The results of the NutriNet-Santé study reveal that restrictive diets, whether marketed or homemade, are much less effective and less well tolerated than following nutritional recommendations. More than three quarters of people who followed these recommendations (76%) believe that this diet was effective in the long term, with a maintenance of weight loss beyond six months, against 61% for the “coached” regimes, 59% for home-made restrictive diets, and 51% for marketed restrictive diets.
Another observation: 17% of subjects affected by restrictive marketed diets consider this method frustrating with regard to food choice, compared to 12% for restrictive homemade diets, 8% for following nutritional recommendations, and only 3% for diets. balanced with coaching.
“These results support a clear message that restrictive ‘commercial’ diets are less effective in the long term, especially when they are repeated compared to diets based on nutritional recommendations. complicated, more frustrating and more difficult to implement than diets based on global nutritional recommendations, ”say the authors of the study.
