高脂低碳餐單，亦即是生酮飲食，越漸普及化，經常標榜為減肥的有效秘方。684Please respect copyright.ＰＥＮＡＮＡBgUE9Hnx6T

的而且確，生酮飲食可以促進脂肪燃燒，而且會大量消耗身體的糖原，而每一個單位的糖原會黏上四個單位的水份關係，生酮飲食短期間會消耗身體水份含量，得以獲取快速的減磅效果。684Please respect copyright.ＰＥＮＡＮＡI9meItcE1H

但另一方面，生酮飲食包含眾多高脂食物，而這些食物一直被指責為心臟病、癡肥糖尿病等的元兇，那麼究竟生酮飲食是好還是壞呢？684Please respect copyright.ＰＥＮＡＮＡvuMjAi0hrn

（圖2）有科學家進行了人體測試(Ref1)，找來14名年齡為27-42歲男性單車運動員，分成兩組進行持續六個月以上的生酮飲食(LCHF)及均衡飲食(Mixed)的飲食管理，成份如圖中所示。684Please respect copyright.ＰＥＮＡＮＡ9SWC6XayXB

（圖3）六個月的餐單後，兩組人各自進食含75克葡萄糖的食物，然後再分別量度血糖及血液胰島素的濃度。684Please respect copyright.ＰＥＮＡＮＡNSdCl6Er15
684Please respect copyright.ＰＥＮＡＮＡ5ui1fz2eWk
684Please respect copyright.ＰＥＮＡＮＡgDQbLeqPum
如左圖所示，生酮飲食(LCHF)組別的血糖明顯比均衡飲食(Mixed)為高。684Please respect copyright.ＰＥＮＡＮＡ1YtuPQ7QeE
684Please respect copyright.ＰＥＮＡＮＡHBZrVHNKPl
而且亦可見生酮飲食(LCHF)組別胰島素的產生時間較均衡飲食(Mixed)為延遲。684Please respect copyright.ＰＥＮＡＮＡOMUbg6HYNt
684Please respect copyright.ＰＥＮＡＮＡx39MRb1OU6
這歸咎於生酮飲食(LCHF)組別的肌肉擁有較少GLUT4及IRS1蛋白質；684Please respect copyright.ＰＥＮＡＮＡcpci5Koqs7
GLUT4及IRS1分別為其中一種負責吸取葡萄糖及接收胰島素的蛋白質。684Please respect copyright.ＰＥＮＡＮＡSUM7Aefx4X
684Please respect copyright.ＰＥＮＡＮＡe5GvsKlBdN
（圖4）雖然兩組人員在血糖及胰島素相關方面有顯著分別，但各種與新陳代謝有關的蛋白酶以及肌肉組成的比例，並沒有因為飲食不同而有所轉變。684Please respect copyright.ＰＥＮＡＮＡZi6ZlUDVcE
684Please respect copyright.ＰＥＮＡＮＡtQaCahhSgO
684Please respect copyright.ＰＥＮＡＮＡFBTI9vBpt7
當然，與新陳代謝有關的蛋白酶數量繁多，不能擔保表外的蛋白酶會否有所影響。684Please respect copyright.ＰＥＮＡＮＡWEn9xZBpYT
684Please respect copyright.ＰＥＮＡＮＡUYq3F76SMq
生酮飲食測試者需要更長的時間才能降低血糖，相信是因為長期攝取低碳水化合物而引起的轉變，會否因此增加糖尿病的機會還成未知之數；684Please respect copyright.ＰＥＮＡＮＡCoBUNRDh4S
不過生酮飲食本身就是低糖飲食，血糖理論上不會超標，所以根本沒有相干。684Please respect copyright.ＰＥＮＡＮＡlNt992yf0I
684Please respect copyright.ＰＥＮＡＮＡ4F9Sow3ctN
之於生酮飲食究竟會否引起心臟病等問題，還有待更詳細的長期人體實驗才能證實得到。684Please respect copyright.ＰＥＮＡＮＡKvx6ze0PPD
