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。1059Please respect copyright.ＰＥＮＡＮＡOIkXPpymAZ

一直亦有不少研究試圖探討荷爾蒙與食慾的關係，1059Please respect copyright.ＰＥＮＡＮＡS1JW0RnzDW
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。1059Please respect copyright.ＰＥＮＡＮＡokzDlIejI6

(圖2)我們的食慾由下丘腦(Hypothalamus)所控制。1059Please respect copyright.ＰＥＮＡＮＡds6bDOSVrJ

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。1059Please respect copyright.ＰＥＮＡＮＡP0woQVmGL3

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。1059Please respect copyright.ＰＥＮＡＮＡ5tB35D8Rwb

老鼠缺乏MC4R蛋白質的話，體重亦會明顯上升。1059Please respect copyright.ＰＥＮＡＮＡE0YIsH5RU3
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。1059Please respect copyright.ＰＥＮＡＮＡdFZxserXLh

(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。1059Please respect copyright.ＰＥＮＡＮＡNOsrZrWY2I

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。1059Please respect copyright.ＰＥＮＡＮＡoVlmLaioOc
1059Please respect copyright.ＰＥＮＡＮＡxpPnr0jZ0m
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。1059Please respect copyright.ＰＥＮＡＮＡwq2m5hYU0z
