減低食慾從而減少進食，某程度上亦可看成為對抗肥胖或癡肥的其中一道方法。1082Please respect copyright.ＰＥＮＡＮＡzgUyhEMllA

一直亦有不少研究試圖探討荷爾蒙與食慾的關係，1082Please respect copyright.ＰＥＮＡＮＡA0yBPbVItA
其中之一的目標就是設計出一款能壓抑食慾的藥物，輔助癡肥或糖尿病人的治療。1082Please respect copyright.ＰＥＮＡＮＡixFjBcbNN1

(圖2)我們的食慾由下丘腦(Hypothalamus)所控制。1082Please respect copyright.ＰＥＮＡＮＡ9rJonObPJR

以非常簡化的角度來說，在飽肚狀態下，含有MC4R蛋白質的神經細胞便會受到刺激，我們的食慾亦會隨之受到壓抑。1082Please respect copyright.ＰＥＮＡＮＡ7RcaXWz2Hh

相反，在飢餓狀態下，含有MC4R蛋白質的神經細胞便會受到壓抑，我們的食慾亦會隨之而來。1082Please respect copyright.ＰＥＮＡＮＡsH6ErFHeHw

老鼠缺乏MC4R蛋白質的話，體重亦會明顯上升。1082Please respect copyright.ＰＥＮＡＮＡttmj5ns1Kz
而MC4R的蛋白質因基因變異而導致部份功能的喪失，亦能在不少癡肥人士身上記錄得到。1082Please respect copyright.ＰＥＮＡＮＡOPwszXNqgB

(圖3)刺激MC4R，便能減低食慾，減低食慾，便能減低進食量，有助對抗癡肥。1082Please respect copyright.ＰＥＮＡＮＡclgFg85jg0

第一代刺激MC4R的藥物基於其附帶的血壓上升副作用，不得不終止研究及停止發展。1082Please respect copyright.ＰＥＮＡＮＡ7pCMjgsTRH
1082Please respect copyright.ＰＥＮＡＮＡ9fogVnO7os
而好消息的是，最近(2020年11月)FDA批准了新一代刺激MC4R的藥物Setmelanotide，並沒有血壓上升的副作用，在符合對應的條件下可用作體重管理之用。1082Please respect copyright.ＰＥＮＡＮＡTiCq6ae5Vg
