Effects of Beef Protein Consumption on Energy Intake

The three applied conditions will differ in the relative protein content of the meals, including 5 En%, 15 En% and 30 En% from protein. Beef protein will be used as main meat protein source in the 15 En% and 30 En% protein conditions. The resulting macronutrient compositions of the diets will be En% Protein/Carbohydrate/Fat; 5/60/35, 15/50/35, and 30/35/35. All meals (breakfast, lunch, dinner) within each condition will have the same macronutrient composition. All food items, and the energy density, weight and volume of the meals will be the same between conditions. All snack items will be very low in protein content.
