ABSTRACT: Breakfast is considered an
important meal for daily appetite control. We examined the effect of high-protein
breakfasts on within-day appetite sensations and subsequent ad libitum intake, in men and women. Twenty
subjects attended on 4 occasions, to consume in a randomised order high-protein
(30% energy) breakfast meals, as, 1) maintenance (MTD) fed to energy requirements
(2.67 MJ), 2) a weight-loss (WL) bacon-based meal 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 differences in hunger (p = 0.007), fullness (p =
0.029), desire to eat (p = 0.006) and
prospective consumption (p = 0.020).
The WL-B meal reduced hunger (p = 0.002)
and enhanced fullness (p = 0.02),
compared with the two other WL breakfasts. Although these differences were not
reflected in ad libitum energy intake
later in the day, a HP breakfast can modify morning satiety, which is important
during dieting.
