Figure 1.

Left: mean (±standard error of the mean (SEM)) energy intake at the buffet meal (kcal) in healthy older men (n = 13) after drinks (~450 mL; energy content of the drink as the striped part of each bar) containing either: (i) 70 g whey protein (280 kcal; ‘P₂₈₀’); (ii) 14 g protein, 28 g carbohydrate, 12.4 g fat (280 kcal; ‘M₂₈₀’); (iii) 70 g protein, 28 g carbohydrate, 12.4 g fat (504 kcal; ‘M₅₀₄’); or (iv) an iso-palatable control drink (~2 kcal; ‘control’). Right: mean (±SEM) suppression of energy intake after caloric drinks (P₂₈₀, M₂₈₀ and M₅₀₄) compared to control. ^a,b p < 0.05 Total energy intakes (meal plus drink) for P₂₈₀, M₂₈₀ and M₅₀₄ (^b) were higher compared to the control (^a).
