Are low calorie diets useful?

Very low-calorie diets and maintaining weight loss Much has been said about diets that promote rapid weight loss, but shortly after stopping them, you return to your original weight again or gain more weight; Nowadays, these diets are being studied in order to evaluate their effectiveness on long-term weight maintenance in the treatment of obesity compared to other dietary treatments. There are several factors that make it very difficult to evaluate the long-term effectiveness of weight loss, such as: the definition of long-term, the method used to calculate long-term success, and the comparison of weight loss methods. However, the most problematic aspect is the different weight loss strategies. Study A study was found where long-term observations were made of subjects who followed a very low-calorie diet (MCRD) where they saw that there is a greater initial weight loss that is maintained for a long time when given along with an active weight maintenance program, this includes the modification of habits, education in nutrition and exercise; Since if the complete treatment is not given, it is likely that the patient will regain the weight, due to the adaptation mechanisms that the body has. With a DMBC it was seen that the patient achieved an average weight loss of 2.0 kg in the first 4 to 6 weeks, which decelerated to an average weekly weight loss of 0.8 kg during its use for 6 months. Very low calorie diets are part of the Cambridge Weight Plan system, which allows an average weight loss of 1.3 to 2.0kg per week, and due to the 4 phases it manages: preparation, weight loss, stabilization and maintenance, it is a complete plan, becoming one of the best modalities in the treatment of overweight and obesity, as well as success in long-term weight maintenance.
