Attending to food being eaten ('attentive eating') may reduce later overeating. However, evidence in support of this comes primarily from studies in women. The aims of the current study were to investigate the effect that attentive eating has on later food intake in men and examine potential underlying mechanisms. Using a within-subjects design, 34 men (BMI M = 23.73 kg/m, SD = 2.93; age M = 29.15, SD = 11.99) consumed a fixed lunchtime meal on two study days. On one study day participants were instructed to pay attention to the sensory properties of the meal as they ate (focused attention condition), and on the other study day participants ate lunch normally. Three hours after each lunchtime session, ad libitum consumption of snack food was measured, and measures of memory for the earlier lunchtime meal were completed. Participants remembered the lunch to be significantly more satiating in the focused attention condition compared to the control condition. However, focused attention did not significantly affect later ad libitum snack intake or other measures of meal memory. Further research is needed to understand when focused attention influences subsequent food intake before this approach can be used effectively to reduce food intake.
关注正在吃的食物(“专心进食”)可能会减少之后的过量进食。然而,支持这一观点的证据主要来自于针对女性的研究。本研究的目的是调查专心进食对男性之后食物摄入量的影响,并探讨潜在的机制。研究采用了被试内设计,共有 34 名男性(BMI 平均值为 23.73kg/m2,标准差为 2.93;年龄平均值为 29.15 岁,标准差为 11.99 岁)在两天的研究日里吃固定的午餐。在其中一天的研究中,参与者被要求在进食时关注食物的感官特性(专注注意力条件),而在另一天的研究中,参与者正常吃午餐。午餐后 3 小时,测量参与者随意食用零食的摄入量,并完成对之前午餐的记忆测试。与对照组相比,参与者在专注注意力条件下对午餐的饱腹感记忆明显更强。然而,专注注意力并没有显著影响之后随意食用零食的摄入量或其他对午餐的记忆测试。在这种方法可以有效减少食物摄入量之前,还需要进一步研究专注注意力何时会影响之后的食物摄入量。
