摘要： 限制饮食是为了控制体重, 长期严格地控制进食的倾向。大量研究表明相对于非限制性饮食者, 限制性饮食者对食物线索尤其是高能量或高美味食物线索存在认知偏向。这种偏向是基于一定的脑神经基础的如前额叶背内侧, 小脑等区域。未来研究应设置严格的筛选标准, 运用视觉odd-one-out和学习-再认实验范式, 重视认知神经机制的探讨, 开展中国限制性饮食者对食物线索加工的认知机制和主要影响因素模型的系统研究。

Abstract: Restricted eating refers to consistent, cognitively-mediated efforts to restrict eating for the purpose of weight control. Considerable study has indicated that restricted eaters have cognitive biases in processing food cues, particularly high-energy or palatable food cues, relative to unrestricted eaters. Such biases are associated with specific patterns of electrophysiological activation in regions including the medial prefrontal cortex and cerebellum. Future experimental studies on restricted eating should employ strict selection criteria and employ varied methodological strategies including the odd-one-out and study-test paradigms to elucidate neural bases related to processing food cues and fully identify associated cognitive mechanisms and psychosocial influences in samples of Chinese restricted eaters.
