This study was performed to investigate the effect of a high-fat diet and alcohol (high-fat, alcohol) intake on subsequent spontaneous energy intake when controlling for food energy density. Twelve adults males participated in two 1-d randomly assigned sessions that only differed by the macronutrient composition of the appetizer served at lunchtime. Dietary energy was mainly provided by lipid and alcohol in one appetizer whereas carbohydrate was the main source of energy in the other appetizer. The energy density, content, and weight of the foods were comparable in the two appetizers. Ad libitum energy intake measured at lunchtime after ingestion of the high-fat, alcohol appetizer exceeded that observed after the high-carbohydrate appetizer by >812kJ (P<0.01). This overfeeding had no detectable effect on postprandial hunger and was not compensated by changes in energy intake at dinnertime. In conclusion, this study demonstrates that a high-fat diet and alcohol favor subsequent overfeeding, which is not due to their higher energy density.
本研究旨在探讨在控制食物能量密度的情况下，高脂饮食和酒精摄入对后续自发能量摄入的影响。12名成年男性参加了两个为期1天的随机分配试验，这两个试验仅在午餐时提供的开胃菜的宏量营养素组成上有所不同。在一种开胃菜中，膳食能量主要由脂质和酒精提供，而在另一种开胃菜中，碳水化合物是主要能量来源。两种开胃菜中食物的能量密度、含量和重量相当。摄入高脂、含酒精开胃菜后午餐时测量的随意能量摄入量比摄入高碳水化合物开胃菜后观察到的摄入量高出>812kJ（P<0.01）。这种过度喂养对餐后饥饿没有可检测到的影响，并且在晚餐时的能量摄入量变化也没有对其进行补偿。总之，本研究表明高脂饮食和酒精有利于后续的过度喂养，这并非由于它们较高的能量密度。
