The impact of the covert manipulation of macronutrient intake on energy intake and the variability in daily food intake in nonobese men

To investigate the effect of macronutrient composition on ad libitum food intake in nonobese men. Balanced, incomplete-block, crossover study where subjects received two of three treatments. Macronutrient composition was manipulated by providing 2.1 MJ/day high-carbohydrate (CHO), high-fat (FAT), an...

Zusammenfassung:To investigate the effect of macronutrient composition on ad libitum food intake in nonobese men. Balanced, incomplete-block, crossover study where subjects received two of three treatments. Macronutrient composition was manipulated by providing 2.1 MJ/day high-carbohydrate (CHO), high-fat (FAT), and/or high-protein (PRO) drinks every day over the course of two, 8-week periods. In all, 12 healthy normal weight men (age: 39+/-9 years, BMI: 24.1+/-1.4 kg/m2). Ad libitum food intake was measured continuously for 16 weeks at the Beltsville Human Nutrition Research Center (BHNRC). Body composition (DEXA) and body weight were also measured. Average energy intake (EI) during weeks 1 and 2 was lower for CHO than FAT (P
