I am afraid that my 11 year old daughter is eating to much- she is tall, about 5 5 and is active by running track, and cheering, tumbling for two hours x3 nights a week. But she still has a tummy. When she says she is hungry, we suggest fruit and or yogurt- we don t keep junk food in the house, no chips or sodas or sweets. How many calories do you suggest and do we need to keep track of carbs or fats?
