I tend to take this outlook. Almost all forms of calorie restriction works. When I personally point out that a calorie is not a calorie it has everything to do with satiation, motivation and the psychology of what makes people over-eat. Limiting calories works. Keeping people doing that long enough to lose weight, and the rest of their lives to some degree (so no yo-you dieting) is the true challenge.
