What is a metabolic advantage?
Dr. Michael Eades explains it this way:
When two groups of subjects both eat the same number of calories (but provided by diets of different macronutrient compositions) and maintain the same activity level, yet one group loses more weight than the other, the group losing the greater weight is said to have a metabolic advantage. Or, more specifically, the diet driving the weight loss is said to provide a metabolic advantage.Dr. Eades further explains metabolic advantage in his blog post.
The literature does show an apparent metabolic advantage in studies.
The evidence continues to grow, that lower carbohydrate diets result in greater weight loss and less hunger, than calorie reduced diets.
