SUMMARY
Ketogenic diets and weight loss: basis and effectiveness
The international consensus is that carbohydrates are the basis of the food pyramid of a healthy diet. Today's specialists believe that the best way to lose weight is by cutting down on calories, essentialy in the form of fat. However, this paper will clarify that ketogenic diets are, from a physiological, biochemicale and practical point of view, a much more effective way of losing weight, since such diets provide metabolic advantages such as the capacity to preserve muscle mass, reduce appetite, to have a lower metabolic efficiency, produce a metabolic activation of thermogenesis and favour a greater fat loss even with a greater number of calories.

Keywords: Atkins, high protein diets, low carbohydrate diets, ketosis, glycolytic, lipolytic, obesity, weight loss.
