There are all kinds. Generally speaking, diets can be classified according to their "target". We will therefore retain three categories: low-carbohydrate diets, such as the Atkins diet; low fat diets, such as the Ornish diet; and finally moderate macronutrient diets, such as the Weight Watchers formula. The first pushes to consume less carbohydrates to promote the phenomenon of lipid oxidation, which leads to a decrease in appetite. The second aim to reduce lipids, so that they correspond to only 10-20% of the total calorie intake, and to favor fruits and vegetables in order to increase satiety, thanks to greater quantities consumed. Finally, the moderate macronutrient diet encourages you to eat everything, but in smaller quantities.

Every year new diets appear in the pages of magazines and books on the subject. But what is the right method to lose weight effectively and sustainably? Researchers have analyzed the results of studies and come to their conclusion.

The obesity epidemic that certain countries are experiencing is pushing scientists to research the causes of this pathology and the means to be implemented to obtain lasting weight loss in affected patients. Which diets prove to be effective? What is the ideal speed for weight loss? Will the weight lost quickly be regained as quickly?

Does the ideal diet exist?

Researchers performed a meta-analysis to compare the results of different studies of these different diets. Over 7,000 participants following eleven different diets were therefore studied by observing their weight loss and body mass index (BMI) at six and twelve months of the start of the diet. According to this analysis, diets low in carbohydrates and fat show the best results. However, the researchers also note that the differences between the diets are minimal and that the weight loss gradually decreases over time, only to regress completely at twelve months. This finding reveals the difficulty of long-term weight loss and underlines that the notion of adherence to the diet is more important. The patient must therefore find the formula that suits him and that he will be able to respect, in the long term.
