title: Effect of weight loss plans on body composition and diet duration.
abstract: Are low carbohydrate high protein (LCHP) diets more effective in promoting loss of weight and body fat and can individuals stay on an Atkins-like diet more easily than on a conventional weight loss diet? A pre-test/post-test randomized group design composed of three cohorts was utilized to test 1) a LCHP ketogenic diet; 2) the Zone diet; and 3) a conventional hypocaloric diabetic exchange diet that supplied < 10%, 40%, and 50% of calories from carbohydrate, respectively. Body composition was measured before and after the intervention treatment period with dual energy X-ray absorptiometry. Mean weight loss was 5.1 kg for those who completed the 12-week program. There were no significant differences in total weight, fat, or lean body mass loss when compared by diet group. Attrition was substantial for all plans at 43%, 60%, and 36% for LCHP, Zone and conventional diets, respectively.
