Nutritionists and dieting experts have long sought the answer to how to encourage people to lose weight. It seems overweight people are more interested in the size of their wallets than their waistlines. Researchers in the USA may have found one answer – cash rewards and penalties. A year-long study of 100 weight watchers by the Mayo Clinic in Minnesota found a system of financial incentives and fines had a significant impact on people's success in shedding kilos. The weight-conscious dieters received $20 a month if they met their weight loss goals and had to pay a penalty if they didn't. Those motivated by financial gain lost an average of 4.1kg, compared to just 1kg for those without the cash bonus.

營養(yǎng)學(xué)家和節(jié)食專家長期以來一直尋找如何鼓勵人們減肥的答案。看上去似乎超重的人對他們錢包的厚度比對腰圍的尺寸更感興趣。美國研究人員可能發(fā)現(xiàn)了一個答案——現(xiàn)金獎勵和懲罰。明尼蘇達梅奧診所對100名超重者進行的長達一年的研究發(fā)現(xiàn)一個經(jīng)濟獎懲系統(tǒng)對激勵人們減肥有著重要影響。在意體重的節(jié)食者如果達到了減肥目標每月可以獲得20美元的獎勵，如果沒有達到目標必須繳納罰款。受到現(xiàn)金獎勵激勵的人平均減肥4.1千克，而沒有獎金的人只減肥1千克。

The study followed 100 obese adults aged between 18 to 63, who were weighed every month for a year. They were put into four groups, some with a monetary focus, others with an emphasis on education and behaviour change. The $20 a month was enough for the financially-motivated dieters to out-diet the other groups. Mayo Clinic's Dr Donald Hensrud said: "Just wanting to lose weight isn't enough. Financial incentives can be powerful." Head researcher Dr Steven Driver found the fear of losing money was stronger than the thought of receiving a bonus. He said: "Fear of losing money tends to motivate people about two and a half times more than the prospect of gaining the same amount of money."

這項研究追蹤了100名介于18歲到63歲的肥胖成年人，一年之內(nèi)每個月都測量體重。他們被分成四個小組，一些有金錢獎勵，其他人則強調(diào)教育和行為方面的改變。每月20美元對于那些受金錢激勵的節(jié)食者來說足以超越另外一組節(jié)食者。梅奧診所的Donald Hensrud博士表示：“僅僅有減肥的想法是不夠的。金錢激勵的威力比較強大。”首席研究員Steven Driver博士發(fā)現(xiàn)，害怕?lián)p失金錢的念頭比得到獎金的念頭更加強烈。他說：“害怕?lián)p失金錢的效果是希望得到同樣金額獎金的效果的2.5倍。”
