高脂肪饮食摄入可能是肥胖的病因和维持的关键。由于来自脂肪的能量比例的降低将伴随着来自碳水化合物的能量比例的增加，因此本研究比较了这些常量营养素对肥胖和瘦弱个体饮食行为的影响。研究人员评估了不同数量的脂肪和碳水化合物对随后的食物摄入、饥饿感和饱腹感的影响。一组12名体重正常的男性，不关心饮食和体重（不受限制），无论营养成分如何，都准确地补偿了预负荷中的能量。其他组（每组n = 12），包括正常体重约束的男性和正常体重和肥胖的约束和不约束的女性，没有这种有序的能量补偿；按焦耳计算，高脂肪预负荷比高碳水化合物预负荷对午餐摄入的抑制作用要小。这些结果表明，对脂肪饱腹效应的相对不敏感可能与肥胖的发展和维持有关。
High intake of dietary fat may be key in both the etiology and maintenance of obesity. Because a reduction in the proportion of energy derived from fat will be accompanied by an increase in the proportion of energy derived from carbohydrate, this study compared the effects of these macronutrients on eating behavior in obese and lean individuals. The effects of different amounts of fat and carbohydrate, covertly incorporated into yogurt preloads, on subsequent food intake, hunger, and satiety were assessed. A group of 12 normal-weight men, unconcerned about eating and body weight (unrestrained), accurately compensated for the energy in the preloads regardless of the nutrient composition. Other groups (n = 12 per group), including normal-weight restrained men and normal-weight and obese restrained and unrestrained females, did not show such orderly energy compensation; joule-for-joule, the high-fat preloads suppressed intake at lunch less than did high-carbohydrate preloads. These results suggest that a relative insensitivity to the satiating effect of fat could be involved in the development and maintenance of obesity.
