||Breakfast is thought to be an important meal to control appetite. We examined the effect of high-protein breakfasts on within-day appetite and ad libitum intake, in men and women. Twenty subjects attended on 4 occasions, to consume a high-protein (30% energy) breakfast meal, corresponding to, (1) a maintenance breakfast (MTD) fed to energy requirements (2.67 MJ), (2) a weight-loss (WL) bacon breakfast (WL-B, 2.13 MJ), (3) a WL-chicken salad (WL-CS, 2.13 MJ) and (4) a WL-smoothie (WL-S, 2.08 MJ). The 3 HP-WL breakfasts elicited significant differences in hunger (p=0.007), fullness (p=0.029), desire to eat (p=0.006) and prospective consumption (p=0.020), whereby the WL-B breakfast reduced hunger and enhanced fullness, compared to the two other WL breakfasts, comparative to the maintenance breakfast. However, this was not reflected in subsequent energy intake, with no difference up to 5.5h after breakfast. Breakfast meal type is an important choice influencing morning motivation to eat.
