膳食脂肪在调节能量摄入中的作用通过操纵常规饮食和测量自发食物消耗来评估。24名女性每人接受了一系列为期3周的饮食治疗，其中15- 20%、30- 35%或45-50%的能量来自脂肪。这些饮食由外观和适口性相似但所用高脂肪成分量不同的食物组成。相对于中等脂肪饮食的能量消耗，受试者自发地消耗了11.3%的低脂肪饮食和15.4%的高脂肪饮食（p < 0.0001），导致体重的显著变化（p < 0.001）。确实发生了少量的热量补偿（p < 0.02），这在最瘦的受试者中最大（p < 0.03）。这些结果表明，习惯性、不受限制地食用低脂饮食可能是控制体重的有效方法。
The role of dietary fat in the regulation of energy intake was assessed by manipulating a conventional diet and measuring spontaneous food consumption. Twenty-four women each consumed a sequence of three 2-wk dietary treatments in which 15-20%, 30-35%, or 45-50% of the energy was derived from fat. These diets consisted of foods that were similar in appearance and palatability but differed in the amount of high-fat ingredients used. Relative to their energy consumption on the medium-fat diet, the subjects spontaneously consumed an 11.3% deficit on the low-fat diet and a 15.4% surfeit on the high-fat diet (p < 0.0001), resulting in significant changes in body weight (p < 0.001). A small amount of caloric compensation did occur (p < 0.02), which was greatest in the leanest subjects (p < 0.03). These results suggest that habitual, unrestricted consumption of low-fat diets may be an effective approach to weight control.
