Out of curiousity I clicked on one of the articles you linked to: "...during a 6-wk period of hospitalization. Consequently, 43 adult, obese persons were randomly assigned to receive diets containing 4.2 MJ/d (1000 kcal/d) composed of either 32% protein, 15% carbohydrate, and 53% fat, or 29% protein, 45% carbohydrate, and 26% fat."
A 6-week period with only 43 participants? ...how does this get published?
