I don't think that anyone's ever claimed calories_in=calories_out to be strictly true. The point is rather that it's approximately true and whilst the real equation might be calories_in=calories_out+some_wastage, you're really not going to get much headway by attempting to change the last of these when there are far more obvious gains to be had with the other two. The bottom line is that there's no substitute for a calorie-controlled diet and a reasonable amount of exercise; well at least nothing short of some rather unpleasant drugs or major surgery at any rate.
