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. 

科学家日前证实，绝大多数尝试节食或运动减肥的肥胖人群体重都会反弹。

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. 在英国每年的1200万节食减肥人群中，只有不到10%能成功减去大量体重，而其中绝大多数人会在一年内反弹。

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. 

该研究进一步印证了“溜溜球节食效应”的普遍性，它是指减肥者陷入反复减肥的恶性循环。共有2.5万人参与了此项调查。
