总热量不超标也无效,进食时间是关键
维尔美诊所院长刘浩文引用2026年发表于《Clinical Gastroenterology and Hepatology》的研究指出,习惯在晚餐后或睡前吃宵夜的人,代谢性脂肪肝风险飙升36%,肝硬化风险增加28%,排除夜班干扰后甚至高达49%;不吃早餐则无显著关联。

文章引用2026年发表于《Clinical Gastroenterology and Hepatology》的研究,由美国麻省总医院等团队结合三大世代研究,追踪199,155名原本没有肝病的成年人长达16年,探讨进食时间对肝脏的影响。
很多人以為只要「每天總熱量沒超標」、平常也滴酒不沾,睡前吃點健康的宵夜不會怎樣。維爾美診所院長劉浩文於Threads「劉浩文醫師」引用 2026 年最新發表在腸胃肝膽科期刊《Clinical Gastroenterology and Hepatology》的研究,給了所有夜貓子一個當頭棒喝:真正把肝臟推向發炎與硬化的,往往不是你吃了多少,而是你「幾點吃」!
劉浩文表示自己曾被病患問到「我不喝酒,一天也只吃兩餐,怎麼會有脂肪肝?」劉浩文引用研究指出,美國麻省總醫院等研究團隊結合了三大知名世代研究,追蹤了高達 199,155 名原本沒有肝病的成年人,時間長達 16 年,目的是找出「進食時間」對肝臟的影響。
當科學家把年齡、BMI(胖瘦)、每天攝取的「總熱量」、運動量、酒精攝取,甚至連「吃得健不健康(飲食指標 AHEI)」全部校正扣掉之後,發現了三個驚人的發現:
宵夜是獨立的傷肝元兇:習慣在晚餐後或睡前吃東西(Late-night eating)的人,罹患「代謝性脂肪肝(MASLD)」的風險直接飆升 36%!
連肝硬化風險都大增:同樣這群愛吃宵夜的人,未來發生「肝硬化」的風險顯著增加了 28%;如果進一步排除夜班輪班工作的干擾,吃宵夜導致肝硬化的風險甚至高達 49%!
「不吃早餐」被冤枉:很多人實施 168 斷食會選擇不吃早餐,研究發現,在校正了整體生活習慣後,「不吃早餐」跟脂肪肝或肝硬化沒有顯著關聯。真正的致命傷,是進食時間往深夜推進!
為什麼明明總熱量一樣,晚上吃就會變成脂肪肝?研究說明:我們的肝臟有一座精密的「內在生理時鐘(Circadian clock)」;一到夜晚,身體準備休息,肝臟的「夜間胰島素阻抗」會自然升高,能量消耗率也會下降。
這時候塞食物進去,肝臟處理不了這些糖分與能量,直接啟動「新生脂肪合成(De-novo lipogenesis)」通道。簡單地說正是:把你晚上吃進去的東西,直接就地打包成肝臟裡的油滴存起來!
如果你正在執行 168 斷食,或是想逆轉健檢報告上的脂肪肝紅字;該做的,不是白天餓肚子、留到半夜大吃;而是試著把晚餐時間往前挪,給肝臟一個乾淨、不用加班的夜晚。

Physician Wang Si-heng cited a National Taiwan University Public Health study and pointed out that the average sugar content of 700ml half-sugar hand shake drinks on the market is 46.5 grams, which is close to the daily upper limit; and 55.6% of drinks labeled as no added sugar still contain sugar.
