To evaluate the effects of overeating (140% of energy requirements) a high-fat low-energy density diet (HF/LED, 1.05 kcal/g), high-fat high-energy density diet (HF/HED, 1.60 kcal/g), and high-carbohydrate (HC) LED (1.05 kcal/g) for 2-days on subsequent 4-day energy intake (EI), activity levels, appetite, and mood.
Using a randomized cross-over design, energy expenditure and EI were standardized during overeating.
In 20 adults with a mean ± SD BMI of 30.7 ± 4.6 kg/m(2) , EI was not suppressed until the second day after overeating and accounted for ∼30% of the excess EI. Reductions in EI did not differ among the three diets or across days. Overeating had no effect on subsequent energy expenditure but steps/day decreased after the HC/LED and HF/HED. Sleep time was increased after the HF/HED compared to both LEDs. After overeating a HF/HED vs. HF/LED, carbohydrate cravings, hunger, prospective food consumption, and sadness increased and satisfaction, relaxation, and tranquility decreased.
Diet type, time, or their interaction had no impact on compensation over 4 days. No adaptive thermogenesis was observed. The HF/HED vs. HF/LED had detrimental effects on food cravings, appetite, and mood. These results suggest short-term overeating is associated with incomplete compensation.
评估在 2 天内过量进食（能量需求的 140%）高脂肪低能量密度饮食（HF/LED，1.05 千卡/克）、高脂肪高能量密度饮食（HF/HED，1.60 千卡/克）和高碳水化合物（HC）LED（1.05 千卡/克）对随后 4 天能量摄入（EI）、活动水平、食欲和情绪的影响。
采用随机交叉设计，在过量进食期间标准化能量消耗和 EI。
在 20 名平均 ± SD BMI 为 30.7 ± 4.6 kg/m²的成年人中，EI 直到过量进食后的第二天才受到抑制，约占过量 EI 的 30%。三种饮食或各天之间的 EI 减少没有差异。过量进食对随后的能量消耗没有影响，但在 HC/LED 和 HF/HED 之后，每天的步数减少。与两种 LED 相比，HF/HED 后睡眠时间增加。与 HF/LED 相比，HF/HED 后碳水化合物渴望、饥饿、预期食物消耗和悲伤增加，而满足感、放松和宁静感降低。
饮食类型、时间或其相互作用在 4 天内没有对补偿产生影响。未观察到适应性生热作用。HF/HED 与 HF/LED 相比，对食物渴望、食欲和情绪有不利影响。这些结果表明，短期过量进食与不完全补偿有关。
