Is there a way to speed up your metabolism?

Does anybody know any steps to speed up metabolism? Last year I had anorexia and I went to the hospital and was eating around 2500 to 3000 calories and didn't gain an once Now I am eating god knows probably 1000 to 1500 calories and I can't stop gaining...

weight. What's up with me? I just want to be like a normal kid who can eat what I want and not worry that the next bite is going to make me fat like I used to be! thanks! and ps I already exercise everyday and eat probably 4 times a day. And I also was eating more junk food before and barely exercising.

I heard that drinking ice cold water helps. Your body has to heat it up. But, drink 10 glasses a day.

try to talk to your parents about it. if they dont understand try to see a doctor cause this may not be a healthy thing for some one like you who had this before.

When you exercise more you gain muscles. Having more muscles will then mean a higher metabolism rate.

Just keep a healthy lifestyle; eat normally. Restricting food intake will lessen your metabolism rate and make you more irritable.

The key is balance. I wish you luck and hope you won't become annorexic again.
