I have a friend who's 12 years old and weighs 130 lbs.though she is not considered "overweight" she still wants to lose 20 lbs.what would you recomend?

Still Growing...: How much a person weighs also depends on the person's height. If your friend is not overweight, she should not lose weight. She can concentrate on eating healthy foods and drinking healthy drinks. It would also be advisable for your friend to exercise 1/2 a day several times a week. If you are worried about your friend, you should seek an adult's help.
