Is an overweight child destined to become an overweight adult?

No, but he is definitely at significant risk for becoming an overweight or obese adult. Eighty percent of children overweight at ages 10-15 were obese adults at age 25. And children who are overweight have a 70-80% chance of being an overweight adult for their entire life (American Heart Association, Understanding Childhood Obesity, 2010).

While overweight teens have a seventy percent chance of being an overweight adult, this increases to eighty percent if there is at least one overweight or obese parent (American Heart Association, Understanding Childhood Obesity, 2010.).
