Miracle diets are weight loss diets that have in common the promise of rapid weight loss with little effort , their imbalance in nutrients , very severe restriction of ingested energy, health disadvantages such as loss of muscle mass and muscle mass. increased risk of cardiovascular disease and diabetes – and the lack of a scientific foundation. They can be essentially classified into 4 types: high protein diets (astronaut diet, Mayo diet, Dukan diet, Scardale diet); carbohydrate-rich diets (plan F diet and Prittikin diet); high-fat diets (Atkins diet); and dissociated diets (Hollywood diet and Montignac diet).
Furthermore, according to the Spanish food safety and nutrition agency, an added problem with these "miracle diets" is that they favor a very rapid recovery of lost weight ("rebound" or "yo-yo" effect) . To achieve long-term weight loss, specialists recommend avoiding "miracle" and quick methods, and creating good eating habits, in addition to regular physical exercise .
