Dietary restriction often fails in the face of tempting and palatable foods; however there is evidence that exposure to diet-congruent cues, such as foods associated with 'slimming' may facilitate control over food intake. The present study examined the effect of exposure to a diet-congruent food on subsequent energy intake in active dieters. Using a within-subjects design, restrained eaters who were currently on a diet (n = 13) and unrestrained non-dieters (n = 21) were exposed to a tempting food cue (chocolate) and a diet-congruent food cue (fruit orange) on two separate testing sessions, and subsequent snack intake was measured. Unrestrained non-dieters consumed similar amounts of snack food across conditions, whilst restrained dieters consumed 60% less chocolate (kcal) after exposure to the diet cue compared to the tempting cue. Exposure to a diet-congruent food cues may help dieters control energy intake when tempted by palatable food.
饮食限制在面对诱人且美味的食物时往往会失效；然而，有证据表明，接触与饮食一致的线索，如与“减肥”相关的食物，可能有助于控制食物摄入。本研究考察了暴露于与饮食一致的食物对活跃节食者随后能量摄入的影响。采用被试内设计，当前正在节食的限制饮食者（n=13）和无限制非节食者（n=21）在两次单独的测试中分别暴露于诱人的食物线索（巧克力）和与饮食一致的食物线索（水果橙），并测量随后的零食摄入量。无限制的非节食者在不同条件下摄入的零食量相似，而在暴露于节食线索后，限制饮食者摄入的巧克力（卡路里）减少了 60%。暴露于与饮食一致的食物线索可能有助于节食者在受到美味食物诱惑时控制能量摄入。
