The aim of this study was to further evaluate the validity and clinical meaningfulness of appetite sensations to predict overall energy intake as well as body weight loss.
Men (n = 176) and women (n = 139) involved in six weight loss studies were selected to participate in this study. Visual analogue scales were used to measure appetite sensations before and after a fixed test meal. Fasting appetite sensations, 1 h post-prandial area under the curve (AUC) and the satiety quotient (SQ) were used as predictors of energy intake and body weight loss. Two separate measures of energy intake were used: a buffet style ad libitum test lunch and a three-day self-report dietary record.
One-hour post-prandial AUC for all appetite sensations represented the strongest predictors of ad libitum test lunch energy intake (p < or = 0.001). These associations were more consistent and pronounced for women than men. Only SQ for fullness was associated with ad libitum test lunch energy intake in women. Similar but weaker relationships were found between appetite sensations and the 3-day self-reported energy intake. Weight loss was associated with changes in appetite sensations (p < or = 0.01) and the best predictors of body weight loss were fasting desire to eat; hunger; and PFC (p < or = 0.01).
These results demonstrate that appetite sensations are relatively useful predictors of spontaneous energy intake, free-living total energy intake and body weight loss. They also confirm that SQ for fullness predicts energy intake, at least in women.
本研究旨在进一步评估食欲感觉预测总体能量摄入以及体重减轻的有效性和临床意义。
选取参与六项减肥研究的男性（n = 176）和女性（n = 139）参与本研究。使用视觉模拟量表测量固定测试餐前后的食欲感觉。空腹食欲感觉、餐后1小时曲线下面积（AUC）和饱腹感商数（SQ）被用作能量摄入和体重减轻的预测指标。使用了两种独立的能量摄入测量方法：自助餐式随意测试午餐和为期三天的自我报告饮食记录。
所有食欲感觉的餐后1小时AUC是随意测试午餐能量摄入的最强预测指标（p≤0.001）。这些关联在女性中比男性更一致且更显著。只有饱腹感的SQ与女性随意测试午餐能量摄入相关。在食欲感觉和三天自我报告的能量摄入之间发现了类似但较弱的关系。体重减轻与食欲感觉的变化相关（p≤0.01），体重减轻的最佳预测指标是空腹想吃的欲望、饥饿感和PFC（p≤0.01）。
这些结果表明，食欲感觉是自发能量摄入、自由生活总能量摄入和体重减轻的相对有用的预测指标。它们还证实，至少在女性中，饱腹感的SQ可预测能量摄入。
