食物摄入的调节是多方面的,涵盖多种复杂机制,其中基于负反馈机制的内环境稳态调节系统是其中不可缺少的一部分。在内环境稳态调节系统中,由胃肠道分泌的外周激素发挥了重要作用,我们统称其为胃肠激素。胃肠激素是营养和能量摄入情况反馈到内分泌细胞后分泌的肽类物质,直接或通过迷走神经与脑联系。胃肠激素对于调节营养摄入和能量消耗过程的平衡、维持体重的相对稳定具有重要意义。本文概述了胃肠激素在调节食欲和摄食行为以及运动减肥中发挥的作用。%Regulation of food intake is multifaceted and covers a variety of complex mechanisms.Among them, system of homeostasis which based on negative feedback mechanisms is an indispensible part.In the regulation system of homeostasis,peripheral hormones which secreted from the gastrointestinal tract plays an important role and are called gastrointestinal hormones.Gastrointestinal hormones are peptide materials secreted from enteroendocrine cells after the feedback of nutrient and energy intake,and will communicate with the brain directly or via the vagus nerve.These hormones are crucial for balancing the process of food intake and energy expenditure and maintaining a relatively stable body weight.The paper provides an overview of the role of gastrointestinal hormone in regulating appetite,food intake and weight -losing through exercise.
