Little is known regarding consumption of palatable foods (PFs) for non-homeostatic reasons after weight-loss interventions and if baseline or change in frequency of this kind of eating can predict weight-loss outcomes. Little is also known of the relationship between PF eating for non-homeostatic motives and PF craving. Addressing these gaps is important because cravings and habitual consumption of PFs in the absence of homeostatic need contribute to obesity.
N = 30 adults with a mean 34.8 BMI completed a seven-response choice version of the PEMS (PEMS-7) before and after Gut-Cued Eating (GCE), an intervention that did not ban PFs but instructed them to eat only when stomach-hungry and stop eating before feeling too full. Photos of PFs were also rated pre- and post-GCE.
Frequency of eating PFs for social, reward enhancement, and coping, but not conformity motives, decreased after GCE. The decreases predicted amount of weight loss independent of initial weight and demographics. PF craving also decreased and, while correlated with decreasing PF intake, it did not predict weight loss.
The study is preliminary because GCE was uncontrolled. However, results warrant a controlled investigation. That craving and frequency of consuming PFs for non-homeostatic motives declined with an intervention that did not ban PFs suggests a method that may voluntarily decrease one's intake of PFs. This should facilitate weight-loss and healthy-weight maintenance. Finally, decreased eating for non-homeostatic motives suggests that individuals were no longer using PFs to cope, socialize, and enhance reward, a change with benefits beyond weight loss.
关于减肥干预后因非稳态原因食用美味食物（PFs）的情况，以及这种饮食频率的基线水平或变化是否能预测减肥效果，目前所知甚少。对于出于非稳态动机食用PFs与对PFs的渴望之间的关系，也知之甚少。填补这些空白很重要，因为在没有稳态需求的情况下，对PFs的渴望和习惯性消费会导致肥胖。
30名平均体重指数为34.8的成年人在接受肠道提示饮食（GCE）前后完成了七反应选择版的PEMS（PEMS-7），GCE是一种不禁止PFs但指示他们仅在胃饥饿时进食并在感觉过饱之前停止进食的干预措施。还在GCE前后对PFs的照片进行了评分。
GCE后，出于社交、奖励增强和应对而非从众动机食用PFs的频率降低。这些降低独立于初始体重和人口统计学因素预测了体重减轻的量。对PFs的渴望也降低了，虽然与PFs摄入量的减少相关，但它并不能预测体重减轻。
该研究是初步的，因为GCE未得到控制。然而，结果值得进行对照研究。一种不禁止PFs的干预措施使出于非稳态动机对PFs的渴望和消费频率下降，这表明了一种可能自愿减少PFs摄入量的方法。这应该有助于减肥和维持健康体重。最后，出于非稳态动机的进食减少表明个体不再使用PFs来应对、社交和增强奖励，这种变化的益处不仅仅在于减肥。
