Is there a way to help my daughter lose weight?

Lose weight: This format limits us to a very brief answer. Eat right is the first in order. Not only the portion is important, we now realize that not all calories are alike. The carbohydrates contributes to weight more than other food categories. One can look into 'glycemic index' on the web. It tells us what food to choose or avoid. Next to diet, exercise is obviously mandatory.
