Isovolumetric and Isocaloric Preloads of Various Types of Milk on Food Intake, Subjective Appetite and Glycemic Response

The Effects of Isovolumetric and Isocaloric Preloads of Various Types of Milk on Food Intake, Subjective Appetite and Glycemic Response in Healthy Young Men and Women

The purpose of this protocol is to study the effects of fluid milk products on satiety, food intake, and glucose metabolism in healthy young men and women. Experiment 1: The specific objective is to investigate isovolumetric amounts of milk (2% M.F.), chocolate milk (1% M.F.), a soy beverage, cow's milk-based infant formula, and water (control) on satiety and food intake and on blood glucose before and after a meal. A fixed volume approach is based on the commercially available serving size. Experiment 2 will examine equicaloric amounts of milk (2% M.F.), chocolate milk (1% M.F.), a soy beverage, cow's milk-based infant formula, a glucose drink and water (control) the treatments in order to investigate macronutrient composition on satiety and food intake and on blood glucose before and after the meal.
