In the eyes of professionals like Professor Boris Hansel, nutritionist, only clinical trials of products, such as those required for drugs, would have value. “You give the supplement or the cream to half of the volunteers, the other half have placebos, no one knows what they are taking, and we evaluate the effectiveness. And that, almost no industrial food supplements or creams does not dare to do this type of study”, he regrets.
Alexandra Retion, dietitian nutritionist, nevertheless recognizes that slimming products have a positive effect. “It can help psychologically to start something, they can have a little placebo effect that helps you change your eating behavior, but there is no magic pill. What is important is to change your eating behavior and incorporate regular physical activity.
The market for slimming products now represents 200 million euros, ie one food supplement out of 10 sold in France.
