FATTY LIVER DUE TO
"REDUCTION
L i u We i success f u l l y
slimmed her body but was most
surprised at getting a fatty liver
- due to her grossly inadequate
diet (even with vitamin pills).
Although excessive drinking,
diabetes and obesity are the
causes of fatty liver, others,
e.g. , poor nut r i t i on, h i gh
cholesterol, viral hepatitis, drug
hepatitis and toxic hepatitis, etc.
are also relevant. Poor nutrition
leads to metabolic disturbances
of protein, fat and even liver
me t abo l i sm. As fa t ce l l s
disintegrate, free fatty acids are
released to be removed by the
liver cells. With high free fatty
acid blood levels, the liver cells
have to take up such a large
quantity of fatty acids that fatty
liver may then result. Take good
care : (1) Reduce we i gh t
gradually, say, around 250 gm
per week; (2) Take moderate
and s u s t a i ned phy s i c a l
exercises, e.g., for 30 min, 3 to
5 times per week; (3) Take small
but frequent meals, e.g., 5-8
meals per day, with 50-55%
c a r b o hy d r a t e s , 2 5 - 3 0%
proteins, minimizing on deep
fried and high-calorie food
stuffs. Fatty livers (diagnosed by
deranged liver function blood
tests and imaging studies) due
to rapid weight loss is correct-
able progressively by nutritional
supplements.
在單位組織的例行體檢中，劉薇檢出了脂肪肝！這一結
果不僅讓劉薇本人難以置信，也令單位同事驚訝不已。都說
脂肪肝是胖人的“專利”，可劉薇是出名的瘦美人，為了保
持骨感身材，她一直在減肥。因此，劉薇檢出了脂肪肝，引
起了許多人的關注。
讓她百思不得其解
每天，劉薇除了午餐時吃一點米飯，其餘兩餐一律取消主
食，只吃些水果或蔬菜沙拉。同事問她餓不，她總是笑著搖頭。
劉薇也擔心這樣下去時間長了會導致營養不良，所以她的包包㛐
總裝著維生素片、鈣片，沒事的時候吃上一兩粒。可是劉薇沒想
到，這麼堅持減肥的她竟成了一個脂肪肝患者，真讓她百思不得
其解。
導致脂肪肝的三大元兇
酗酒、糖尿病、營養過剩（肥胖），這是人們常知的導致脂肪
肝的三大元兇。所以，很多人由此推斷，自己不喝酒，沒患糖尿
病，也不肥胖，就不會被脂肪肝“纏”上。其實，還有很多重要原
因也會導致脂肪肝，比如營養不良、高脂血症、病毒性肝炎、藥
物及各種有毒物質中毒等。因此，脂肪肝既是一個獨立的疾病，
又是多種疾病在肝臟的病變過程。
過分追求苗條身材的代價
一個人肥胖與否是有標準的，而現在很多年輕女性不顧自己
“減”出來的脂肪肝
