许多关于摄入行为的研究都集中在食物的大量营养素成分上。然而，如果这些研究不考虑所研究饮食的能量密度（ED），那么这些研究是不完整的，或者可能会产生误导。通过增加预负荷量而不改变宏量营养素含量来降低 ED（千卡/克），可以增强饱腹感并减少随后进餐的能量摄入。当常量营养素的比例恒定时，随意摄入或饱腹感也会受到 ED 的影响。由于人们倾向于吃固定重量的食物，当可用食物的 ED 减少时，能量摄入就会减少。 ED 的影响已在不同体重状况、性别和行为特征的成年人以及 3 至 5 岁儿童中观察到。对 ED 变化的反应机制尚不清楚，持续数天以上的对照研究数据也有限。然而，基于人群的研究和长期临床试验都表明，饮食性 ED 的影响可能是持续的。多项临床试验表明，通过添加水果和蔬菜等富含水分的食物来减少饮食中的 ED 与显着减轻体重有关，即使患者没有被告知限制热量。由于降低膳食能量密度可以为预防和治疗肥胖提供有效的策略，因此需要对其影响的机制以及应用这些发现的方法进行更多研究。
Much of the research in ingestive behavior has focused on the macronutrient composition of foods; however, these studies are incomplete, or could be misleading, if they do not consider the energy density (ED) of the diet under investigation. Lowering the ED (kcal/g) by increasing the volume of preloads without changing macronutrient content can enhance satiety and reduce subsequent energy intake at a meal. Ad libitum intake or satiation has also been shown to be influenced by ED when the proportions of macronutrients are constant. Since people tend to eat a consistent weight of food, when the ED of the available foods is reduced, energy intake is reduced. The effects of ED have been seen in adults of different weight status, sex, and behavioral characteristics, as well as in 3- to 5-year-old children. The mechanisms underlying the response to variations in ED are not yet well understood and data from controlled studies lasting more than several days are limited. However, both population-based studies and long-term clinical trials indicate that the effects of dietary ED can be persistent. Several clinical trials have shown that reducing the ED of the diet by the addition of water-rich foods such as fruits and vegetables was associated with substantial weight loss even when patients were not told to restrict calories. Since lowering dietary energy density could provide effective strategies for the prevention and treatment of obesity, there is a need for more studies of mechanisms underlying the effect and ways to apply these findings.
