A 16-year-old girl is brought into the family practice clinic for her yearly health maintenance examination. Her height is average and her weight is above average. When this is mentioned to her, she blushes and quickly states that she is trying to lose weight. When asked further about her dieting habits, she eventually admits to routinely eating large amounts of food at one sitting, such as two pizzas, a large sandwich, and a gallon of ice cream.
