虽然高强度甜味剂被广泛用于降低食物的能量密度，但人们对其如何影响饥饿感和食物摄入量知之甚少。我们研究了食用含蔗糖或阿斯巴甜的市售食品对主观食欲评级和食物摄入量的影响。当正常体重的未节食的男性和女性分别得到大量高热量或低热量的布丁或果冻，并被指示想吃多少就吃多少时，他们吃了两种食物中不同热量版本的相似重量。尽管产生了热量摄入的差异（高达206千卡），但在2h后提供各种食物时，受试者仅表现出不显著的热量补偿趋势。总热量摄入（预负荷加试验餐）在不同条件下没有差异。通过食用不同热量的食物，受试者的饥饿感、食欲、想吃的量以及所吃食物的味道的愉悦度都出现了类似的下降，而饱腹感则出现了类似的上升。了解食物的热量含量并不影响摄入或食欲，因为知情和不知情的受试者在测试中的反应相似。因此，低热量食物在食用后的几个小时内抑制了饥饿感，但与总能量摄入的显著减少无关。
Although high-intensity sweeteners are widely used to decrease the energy density of foods, little is known about how this affects hunger and food intake. We have studied the effects of consumption of commercially available foods sweetened with either sucrose or aspartame on subjective appetite ratings and food intake. When normal-weight non-dieting males and females were given large portions of either a high- or low-caloric pudding or jello and instructed to eat as much as they liked, they ate similar weights of the different caloric versions of each food. Despite the resulting difference in caloric intake (up to 206 kcal), subjects showed only a nonsignificant trend towards caloric compensation when presented with a variety of foods 2h later. Total caloric intake (preload plus test meal) did not differ between conditions. Ratings of hunger, desire to eat, the amount subjects wanted to eat, and the pleasantness of the taste of the eaten food were similarly decreased and fullness similarly increased by consumption of the different caloric versions of the foods. Awareness of the caloric content of the foods did not influence intake or appetite in that both informed and uninformed subjects responded similarly in the tests. Thus reduced caloric foods suppressed ratings of hunger for several hours after consumption, but were not associated witha significant reduction in total energy intake.
