The popular 5:2 diet, when you eat normally for five days and heavily restrict your intake for two, does work in the short-term, a study has found.

 

一項研究發現,大受歡迎的5:2輕斷食減重法,規定5天正常吃、2天嚴格控制進食,在短期內確實有效。

 

But you can lose about the same amount of weight while on a standard diet of reducing your daily calorie intake in a much less restricted way.

 

然而,每天正常飲食的人,只要稍微減少卡路里的攝取,也會有差不多的減重功效。

 

The weight loss after six months for those on the standard calorie-reduced diet was 5.5kg, while those on the 5:2 diet lost 5.3kg, according to researchers from Austin Health and the University of Melbourne.

 

奧斯汀健康中心和墨爾本大學的研究人員指出,在飲食中減少攝取卡路里的人6個月後體重減輕5.5公斤,執行5:2輕斷食減重法的人則瘦了5.3公斤。

 

The randomized study involved 24 obese male war veterans aged 55-75 years, who had five counselling sessions with a dietitian over the six-month study.

 

這項研究隨機挑選24名年齡介於55歲至75歲的過重男性退伍軍人,他們在受試的6個月間與營養學家進行5次諮詢。

 

One group went on the 5:2 diet – which originated in the UK – restricting them to 600 calories, on two non-consecutive days a week while they ate normally on the other five days.

 

有一組受試者執行源自英國的5:2輕斷食減重法,每週有5天可正常飲食,但在2天不連續的斷食日裡,只能分別攝取600卡路里。

 

The others, who on average had been consuming around 2,400 calories a day, went on a diet cutting their daily intake by 600 calories.

 

另一組受試者原先1天平均攝取約2400卡路里,現在則每天減少600卡路里的攝取量。

 

Men in both groups lost body fat and girth, with the standard calorie-reduced diet group reducing their percentage body fat by an average 2.3% and their waistline by 6.4cm.

 

2組受試者的體脂肪和腰圍都縮水,在飲食中降低卡路里攝取量的人,體脂肪率平均減少2.3%,腰圍縮小6.4公分。

 

The figures for those on the 5:2 group were 1.3% and 8cm.

 

執行5:2輕斷食減重法的人,體脂肪率減少1.3%、腰圍則縮小8公分。
