I was born with asthma and at 4 years old I was put on Prednisone. I was an active kid, I never just sat around yet I gained alot of weight. Im 17 now, I've tried all I can think of and can't even lose 1 pound. I've tried diets, herbalife, diatomaeous earth, exercise, even down to not eating. I've even went to my doctor for help but they just give me a list of what foods to stay away from. Can anyone give me any tips as to how I can lose weight? I don't know if it's water weight I've been carrying around or if it's from eating alot.
