Glucose, Whey Protein and Time to the Next Meal on Mealtime Food Intake in Children

The Effect of Glucose, Whey Protein and Time to the Next Meal on Food Intake and Subjective Appetite in Normal Weight and Overweight/Obese Children

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.
