Human biology has evolved to keep body fat within a range that supports survival. During the last 25 years, obesity biologists have uncovered key aspects of physiology that prevent fat mass from becoming too low. In contrast, the mechanisms that counteract excessive adipose expansion are largely unknown. Evidence dating back to the 1950s suggests the existence of a blood-borne molecule that defends against weight gain. In this article, we discuss the research supporting an "unidentified factor of overfeeding" and models that explain its role in body weight control. If it exists, revealing the identity of this factor could end a long-lasting enigma of energy balance regulation and facilitate a much-needed breakthrough in the pharmacological treatment of obesity.

尚未确定的针对体重增加的荷尔蒙防御机制。



人类生物学已经进化到将身体脂肪保持在支持生存的范围内。在过去 25 年里,肥胖生物学家发现了防止脂肪量过低的生理学关键方面。相比之下,抵消脂肪过度扩张的机制很大程度上是未知的。追溯到 20 世纪 50 年代的证据表明,存在一种可以防止体重增加的血源性分子。在本文中,我们讨论了支持“不明的过度喂养因素”的研究以及解释其在体重控制中的作用的模型。如果它存在,揭示这个因素的身份可能会结束能量平衡调节的长期谜团,并促进肥胖药物治疗方面急需的突破。
