"This article states that both the low fat and low-carb groups had similar daily caloric intake. The mean numbers reported are 1,448 calories for low-carb and 1527 for low-fat. The difference, 79 calories/day, if multiplied by the 356 days of this one- year study, would be 28,124 total calories. Since 3,500 calories = 1 pound, the difference in calories alone would account for an additional weight loss of 8.04 lb for individuals on the low-carb diet. Since that group lost an average of 7.7 lb more during the study, the entire difference can be the result of lower caloric intake. That additional weight loss might also play a role in the greater decline in other risk markers. Am I missing something?."
