This Current Opinion in Behavioral Sciences article reviews trials that evaluated an obesity treatment that combines response-inhibition training with high-calorie foods and training designed to reduce attention for high-calorie foods. Two randomized controlled trials suggest that food-response inhibition and attention training produced significant body-fat loss, along with a reduction in valuation of, and reward-region response to, high-calorie foods. However, these effects did not emerge in a third trial, potentially because this trial used more heterogeneous food images, which reduced inhibition learning and attentional learning. Collectively, results suggest that food-response inhibition and attention training can devalue high-calorie foods and result in weight loss, but only if a homogeneous set of high-calorie and low-calorie food images is used.
这篇发表于《行为科学当前观点》的文章回顾了多项试验，这些试验评估了一种肥胖治疗方法，该方法将反应抑制训练与高热量食物相结合，并进行旨在减少对高热量食物关注的训练。两项随机对照试验表明，食物反应抑制和注意力训练能显著减少体脂，同时降低对高热量食物的重视程度以及奖励区域对高热量食物的反应。然而，在第三项试验中并未出现这些效果，这可能是因为该试验使用了更多种类各异的食物图片，从而降低了抑制学习和注意力学习。总体而言，研究结果表明，食物反应抑制和注意力训练能够降低高热量食物的价值并导致体重减轻，但前提是要使用一组同质的高热量和低热量食物图片。
