Lisa your goal is to get down to 22 percent body fat. Our calories needs are coompletely different. For an overweight person to lose is fairly easy but for a person who has 10 percent to get down to 5 percent is super hard. I can maintain 10 percent without exersing at a bodyweight of around 148.
So....you had 15 pounds to lose (which shouldn't take long for a healthy 18 year old male), you lost it following a plan that you admit you can't maintain without 2 hours of exercise a day. Really Lisa so to get down from 15 percent to 5 percent is farely easy. I had 15 lbs to lose but my bodyfat levels were extremly low.
