You are probably not doing anything wrong, you probably dont have as much extra fat as others have. I for one looked ok at the beginning but I knew I was nearly 50 pounds overweight so there was alot of "fat" that would burn by simply not eating and maintaining consistent metabolism, by never getting to the point where I was hungry... drinking the lemonade consistently all day, and never alot all at once. Dont give up, and remeber this is a cleanse, not a diet, it will get you on the right track, and you will feel better. Then the key is to eat wisely and exercise consistently.
