Is weight loss in persons with overweight or obesity always good for the liver?
超重或肥胖的人減肥有助於改善肝臟健康嗎？
Weight loss is beneficial for liver function but only when it is not too drastic or too quick. Weight reduction by 10% within 3 to 6 months brings an improvement of the health condition – but it must occur according to a schedule, i.e. by about 1 kg per week.13 Any draconian diets aiming for a rapid rate of weight loss are usually not durable, and also may cause a rapid release of large amounts of fats into the bloodstream, with the consequential fattening of the liver. The so-called monotrophic diets, where nutrients from almost exclusively one product group are delivered to the body, will also not help your liver. An example is the popular Dukan’s diet, where excessive ingestion of proteins has a negative effect on liver health.13
減肥對肝功能健康十分有益，但前提是減肥不要太劇烈或太快。 在 3 到 6 個月內減輕 10% 的體重會帶來健康的改善 ，但必須根據適當的計劃來實現，即每週約 0.5-1 公斤。(13) 以劇烈的節食去達致快速減重目標通常不會產生持久的效果，並且會導致大量脂肪和毒素快速釋放到血液中，從而導致肝臟脂肪積聚。 所謂的單一營養飲食也不適合肝臟，因為只靠某一種的營養完全供應給身體。 一個例子是流行的生酮飲食 (攝取少量碳水化合物)，其中過量的蛋白質攝入會對肝臟健康產生負面影響。(13)
