如何避免“溜溜球節(jié)食”？

減重-反彈-減重-反彈……，體重上下波動仿佛溜溜球的軌跡，這種現(xiàn)象被美國減肥專家Kelly D. Brownell命名為減肥的“溜溜球效應(yīng)”(yo-yo effect)，類似的說法還有“溜溜球節(jié)食”(yo-yo dieting)、“溜溜球陷阱”、“體重循環(huán)”等等。

Scientists have confirmed that the majority of overweight people who try to lose weight either by cutting calories or exercising will return to their former size.

科學家日前證實，絕大多數(shù)嘗試節(jié)食或運動減肥的肥胖人群體重都會反彈。

Fewer than 10 percent of the 12million Britons who go on a diet each year succeed in losing significant amounts of weight and most of those who do put it all back on again within a year. 在英國每年的1200萬節(jié)食減肥人群中，只有不到10%能成功減去大量體重，而其中絕大多數(shù)人會在一年內(nèi)反彈。

The study of 25,000 people provides further evidence of the prevalence of ‘yo-yo dieting’ where slimmers get into a cycle of losing weight and regaining it.

該研究進一步印證了“溜溜球節(jié)食效應(yīng)”的普遍性，它是指減肥者陷入反復(fù)減肥的惡性循環(huán)。共有2.5萬人參與了此項調(diào)查。

Dr Rebecca Hardy, the council’s programme leader on body size, said: ‘Once people become overweight, they continue relentlessly upwards. They hardly ever go back down.

理事會體型研究項目負責人麗貝卡•哈代博士說：“人們一旦超重，就會不可收拾地胖下去。很難瘦回來。”

‘A few lose weight but very few get back to normal. The best policy is to prevent people becoming overweight.

“有些人可以減掉一些體重，但很少有人減到正常。最好的辦法就是從開始就不要長胖。”
