Brief summary

The investigators hypothesize that glucose and whey protein given 30 and 60 min before a pizza meal will exert different effects on food intake in adolescent children, and will depend on pubertal stage. Food intake will be measured at 30 and 60 min following a glucose(0.75 g of glucose/kg body weight), whey protein (0.75 g of glucose/kg body weight) or sweetened noncaloric beverage. Subjective appetite will be measured as well.
