Angela, I find myself wondering if part of the success of that method is that, if you take the flavorless calories three times a day, it makes it so that you're not allowed to eat for six hours over the course of the day! Of course, zapping sugar cravings makes it easier not to constantly snack.
Mark, thanks for the clarification! You keep your ratio carbs-fat-protein about the same, but vary your intake of calories to keep your metabolism from adjusting. That makes sense, because it parallels training to some degree -- for running, example, you're supposed to switch your workouts up between distance runs, interval runs, speedwork, fartleks, etc. Also, I'll keep the 8x your body weight in calories thing in mind so I don't go overboard.
