Studies have shown that individuals with low satiety efficiency may be more susceptible to weight gain, but little is known about the effect of weight loss intervention outcomes in these individuals. This study aimed to evaluate the impact of an energy-restricted weight loss intervention on eating behavior traits and psychobehavioral factors in individuals differing in their satiety responsiveness. A pooled cohort of individuals who were overweight or obese ( = 100; aged 39 ± 9 years) participating in a 12- to 15-week weight loss program targeting an energy deficit of 500⁻700 kcal/day were included in this study. Satiety responsiveness was determined by a median split of the mean satiety quotient based on appetite sensations measured in response to a test meal at baseline (low satiety responsiveness (LSR) vs. high satiety responsiveness (HSR)). Anthropometric variables, eating behavior traits, psychobehavioral factors, and ad libitum energy intake were assessed before and after the intervention. Although similar weight loss was observed between the LSR and HSR groups (-3.5 ± 3.2 vs. ⁻3.8 ± 2.8 kg, = 0.64) in response to an energy-restricted weight loss intervention, changes in eating behavior traits were different between groups. Individuals with LSR had a higher increase in cognitive restraint (+5.5 ± 4.1 vs. +3.5 ± 3.5, = 0.02) and some of its subscales and a lower decrease in situational susceptibility to disinhibition (-0.6 ± 1.1 vs. -1.2 ± 1.3, = 0.02) in response to the intervention compared to the HSR group. In conclusion, energy-restricted weight loss intervention seems to trigger undesirable changes in some eating behavior traits in individuals more vulnerable to overeating, which could increase their susceptibility to weight regain.
研究表明，饱腹感效率低的个体更容易体重增加，但对于这些个体的减肥干预效果知之甚少。本研究旨在评估能量限制减肥干预对饱腹感反应不同的个体的饮食行为特征和心理行为因素的影响。本研究纳入了一个超重或肥胖的队列（n=100；年龄 39±9 岁），这些个体参加了为期 12-15 周的减肥计划，目标是每天摄入 500-700 卡路里的能量不足。饱腹感反应通过基于基线时测试餐的食欲感觉测量的平均饱腹感指数的中位数分割来确定（低饱腹感反应（LSR）与高饱腹感反应（HSR））。在干预前后评估了人体测量变量、饮食行为特征、心理行为因素和随意能量摄入。尽管 LSR 和 HSR 组在能量限制减肥干预下观察到相似的体重减轻（-3.5±3.2 与-3.8±2.8kg， = 0.64），但两组之间的饮食行为特征变化不同。LSR 个体的认知约束（+5.5±4.1 与+3.5±3.5， = 0.02）及其一些子量表的增加更高，而情境易感性的下降更低（-0.6±1.1 与-1.2±1.3， = 0.02）干预组。总之，能量限制减肥干预似乎会在对暴饮暴食更敏感的个体中引发一些饮食行为特征的不良变化，这可能会增加他们体重反弹的易感性。
