目的：饮食行为受内外因素影响。视觉是影响用餐时食物摄入量的复杂因素模式的一部分。本研究旨在探讨视觉对进食行为微观结构和主观进食动机的影响。研究方法与步骤：9名盲人受试者和9名匹配的有视力对照者，分别食用一份由饮食监测仪VIKTOR登记的标准化膳食，测量饮食行为的微观结构。对照受试者的进食行为记录两次，分别是蒙眼和不蒙眼。结果：失明受试者的饮食行为与正常对照组无明显差异。然而，蒙眼进食的受试者的进食行为显示出视力对进食行为的明显影响。蒙眼时，受试者食量减少22% (p < 0.05)，用餐时间缩短（p < 0.05），进食减速曲线减小（p < 0.05）。尽管蒙上眼睛吃的食物量较少，但报告的饱腹感与不蒙上眼睛吃大餐后报告的饱腹感相同。讨论：本研究进一步强调了视觉在调节我们饮食行为中的重要性。蒙着眼睛吃饭会减少食物的摄入量，但不会让受试者感到不饱。因此，蒙眼进食可能会迫使受试者更多地依赖于内部信号。这些结果可能有助于开发针对肥胖受试者的新治疗策略。
Objective: Eating behavior is influenced by internal and external factors. Vision is one part of the complex pattern of factors influencing the amount of food consumed during a meal. The aim of this study was to explore the impact of vision on the microstructure of eating behavior and the subjective motivation to eat.Research Methods and Procedures: Nine blind subjects and nine matched seeing control subjects consumed a standardized meal registered by VIKTOR, an eating monitor, measuring the microstructure of the eating behavior. The eating, behavior of the control subjects was registered twice, with and without blindfold.Results: The eating behavior of the blind subjects did not differ from that of seeing control subjects. However, the eating behavior of seeing subjects eating with blindfold demonstrated a clear impact of vision on eating behavior. When blindfolded, subjects ate 22% less food (p < 0.05), had shorter meal durations (p < 0.05), and had less decelerated eating curves (p < 0.05). Despite a smaller amount of food consumed when blindfolded, the reported feeling of fullness was identical to that reported after the larger meal consumed without blindfold.Discussion: The importance of vision in regulating our eating behavior is further stressed in this study. Eating with a blindfold decreased the intake of food, without making subjects feel less full. Eating blindfolded, therefore, may force subjects to rely more on internal signals. These results might be used as an aid in the development of new treatment strategies for obese subjects.
