By rating his results in terms of body composition instead of scale weight, it becomes clear how Chris has failed. Fifty-five percent of his weight loss came from lean body mass. The drop in lean body mass decreased his metabolism, so he is now burning fewer calories each day than when he started. This has set him up for a relapse. Even if he doesn’t give in to hunger and binge, but simply goes back to the way he used to eat, his body no longer burns calories as efficiently as before.
