Dietas bajas en hidratos de carbono frente a dietas bajas en grasas

The substantial increase in the prevalence of the obesity in the Western world over the past few decades has prompted the creation of strategies to help control this problem. The real effectiveness of any medical therapy will depend on adherence to the treatment prescribed. In the case of obesity, adherence will depend on the patient's motivation to lose weight and on the intrinsic characteristics of the reducing diet, and will be reinforced by positive results. In recent years, low carbohydrate diets have been proposed as an alternative to the traditional low energy and low fat diets. Since 2003, several randomized studies lasting more than 6 months have assessed their efficacy by comparing them with other nutritional strategies. In conclusion, independently of other metabolic considerations, weight loss at 12 months was no greater with low carbohydrate diets than with other alternatives, fundamentally because of low adherence to the diet itself.
