食物的能量密度（艾德;千卡/克），当在实验室中操作时，会影响短期能量摄入。这项研究的目的是检查，如果有选择，饮食艾德（仅食物）和能量摄入量（表示为受试者的估计每日能量需求的百分比）在一个自我选择的，单一的膳食不同的青少年出生与不同的肥胖家族易感性，并作为他们的性别的功能。受试者（13名男性，17名女性）年龄为12岁，根据母亲孕前体重指数（BMI; kg/m2），出生时肥胖风险高（HR; n = 15）或风险低（LR; n = 15）。自助餐，作为午餐供应，随意食用，包括各种食物和饮料，ED范围。HR受试者比LR受试者消耗更多的能量密度餐（仅食物）（1.84 vs. 1.42 kcal/g; P = 0.02），男性比女性消耗更多的能量密度餐（1.83 vs. 1.43 kcal/g; P = 0.03）。总能量摄入，当表示为受试者每日EER的百分比时，HR和LR受试者之间没有差异（42% vs. 33%; P = 0.16）。与女性相比，男性在用餐期间从食物和饮料中消耗的能量多出59%（46 vs. 29%; P = 0.008）。在一顿多项目的午餐中，有肥胖家族倾向的青少年和男性，独立于他们的肥胖风险状况，自我选择了一顿能量密度更高的午餐。肥胖的家族风险，通过遗传或环境途径，可能会促进更高能量密度的饮食。
The energy density (ED; kcal/g) of foods, when manipulated in the laboratory, affects short-term energy intake. The aim of this study was to examine if, when given a choice, dietary ED (foods only) and energy intake (expressed as a percentage of subjects’ estimated daily energy requirement) at a self-selected, single meal differs for teens born with a different familial predisposition to obesity and as a function of their sex. Subjects (13 males, 17 females) were 12 years of age and born at high-risk (HR; n = 15) or low-risk (LR; n = 15) for obesity based on maternal pre-pregnancy body mass index (BMI; kg/m2). The buffet meal, served for lunch and consumed ad libitum, consisted of a variety of foods and beverages with a range in ED. HR subjects consumed a more energy-dense meal (foods only) than LR subjects (1.84 vs. 1.42 kcal/g; P = 0.02) and males consumed a more energy-dense meal than females (1.83 vs. 1.43 kcal/g; P = 0.03). Total energy intake, when expressed as a percentage of subjects’ daily EER, did not differ between HR and LR subjects (42% vs. 33%; P = 0.16). Males, compared to females, consumed ∼ 59% more energy from foods and beverages during the meal (46 vs. 29%; P = 0.008). During a single multi-item lunch meal, teens with a familial predisposition to obesity and males, independent of their obesity risk status, self-selected a more energy-dense meal. Familial risk for obesity, through either genetic or environmental pathways, may facilitate a more energy-dense diet.
