前负荷和试验餐之间时间间隔的差异可能是以前前负荷研究中发现的乳清蛋白饱腹效应的差异。目的是比较乳清蛋白（包括糖巨肽）和麦芽糖糊精碳水化合物的饱腹效果（在摄入前负荷后的设定时间随意进食），并确定这种效果是否受到前负荷时间的影响。在9个独立的日子里，19名健康正常体重的女性在自由进食测试餐前30、60或120分钟食用含有水、或麦芽糖糊精、或乳清蛋白的混合组合物预负荷。乳清蛋白比麦芽糊精和水更能减少试验餐的食物摄入量（p < 0.05）（相应的食物能量摄入量为2343、2584和3135 kJ）。前负荷和试验餐之间的时间间隔不影响食物摄入反应。总能量摄入（前负荷+测试餐）不同，富含麦芽糊精的前负荷的摄入大于富含乳清蛋白的前负荷的摄入，富含乳清蛋白的前负荷的摄入大于水对照的摄入。总能量摄入量分别为3955、3676和3135千焦。食欲的主观评级不支持乳清蛋白相对于麦芽糖糊精对食物摄入的更大饱腹效果，但有证据表明麦芽糖糊精和乳清蛋白相对于水对照具有饱腹效果。(C)2012爱思唯尔有限公司保留所有权利。
Differences in the time interval between preload and test meal may account for the variation in the satiating effects of whey protein found in previous preload studies. The objective was to compare the satiating effects (ad libitum meal intake at a set time after ingestion of preload) of whey protein (including glycomacropeptide) and maltodextrin carbohydrate and to determine whether such effects were influenced by the timing of preloads. On nine separate days, 19 healthy normal weight women consumed mixed composition preloads containing either water, or maltodextrin, or whey protein, 30, 60 or 120 min before an ad libitum test meal. Whey protein reduced food intake (p < 0.05) at the test meal more than maltodextrin and water (respective food energy intakes were 2343, 2584 and 3135 kJ). The time interval between preload and test meal did not affect the food intake response. Total energy intake (preload + test meal) differed, with intake for the maltodextrin-enriched preload being greater than that for the whey protein-enriched preload, which was greater than for the water control. Total respective energy intakes were 3955, 3676 and 3135 kJ. Subjective ratings of appetite did not support a greater satiating effect of whey protein versus maltodextrin on food intake but there was evidence for a satiating effect of maltodextrin and whey protein versus the water control.
