The point was made quite clear: "The main finding from the trial was that diets with varying emphases on carbohydrate, fat and protein levels all achieved clinically meaningful weight loss and maintenance of weight loss over a two-year period." The study was to show that several different diets with the same caloric intake, but different ratios of carbs, fat, and protein all produced the same weight loss. How you get that they were comparing the caloric input of varying diets, I have no idea. The objective was to have the same caloric input for all of the diets, and only vary ratios of food types. One variable at a time, like any good study.
