摘要

热力学第二定律断言,系统内的能量一定是守恒的,变化是由能量输入或输出的变化引起的。在肥胖中,这一原理意味着体重的变化(能量以甘油三酯的形式储存在脂肪组织中)是由能量摄入或消耗的改变引起的。为了保持稳定的体重,能量摄入必须与能量消耗平衡。这一理论导致了一种假设,即来自脂肪组织的激素可以向大脑发出能量储存状态的信号,这标志着理解能量平衡的新时代。1949年,杰克逊实验室的研究人员培育出ob/ob小鼠系,这种小鼠系有一种自发突变,可导致贪食、严重肥胖、高血糖、高胰岛素血症和不孕症。异种共生实验表明,野生型小鼠与ob/ob小鼠配对,可抑制ob/ob小鼠的体重增加,减少食物摄入量,降低胰岛素和葡萄糖水平。这些发现表明,来自野生型伴侣的ob(现在被称为Lep)基因座编码的循环饱腹感因子可能从脂肪组织向中枢神经系统发出信号,通过调节食物摄入和能量消耗来调节体重。
