low carb metabolic advantage...not really

e interesanta schimbarea de pozitie a autorului unui studiu care afirma in 2006 existenta unui avantaj metabolic al dietelor low carb (chiar keto)...aici

"Thus, the primary reason why low-carbohydrate diets tend to show superior weight loss in the short-term has nothing to do with a metabolic advantage, or an effect on insulin, or some other magical unknown effect. It all has to do with appetite control. When people consume a low-carbohydrate, high-protein diet, they are getting a “double-whammy” in regards to appetite regulation. They’re getting the dramatic benefit of increasing protein, and an additional (although smaller) benefit of a ketogenic diet. The bottom line is that the people on these diets spontaneously eat less….A LOT less.

The bottom line is that there is no metabolic advantage to a low carbohydrate intake that is independent of a high protein intake. There is a metabolic advantage to a high protein diet, which will increase the calories you burn by 80-100 calories per day. There is also a dramatic satiety advantage to a high protein intake. A low carbohydrate intake (low enough to cause ketosis) can increase this satiety advantage, but individual responses will vary. The best dietary approach for you will depend upon a variety of factors."
