One of the major problems with nutrition is the ambiguity of usage of phrases such “low-carb”. Does it means the percentage of calories in a diet or the absolute levels. Another problem is the growing number of “experts” who often don’t have any type of command of the literature. A high-carb diet both in percentage of carbs or absolute number of carbs is always an easy target. A better question than weight loss is what is the ideal balance of protein to glycemic load to generate the optimal long-term health benefits for a person. From that perspective the clear winner is the Zone Diet in terms of inflammation control and metabolic advantages. In addition, studies from Harvard Medical School indicate that the standard “low-carb” diet (i.e. Atkins or ketogenic diets) increases cortisol and decreases thyroid hormone production. Neither is good for long-term health. What you need is balance, and that starts with better definitions of diets.
