D: One thing you listeners don't know about me is that I used to weigh an incredible three hundred pounds. Ever since I started the Moment of Science weight loss program, though, I've been slimming and trimming until I'm now in the spectacular  shape you see today. (来源：英语博客 http://space.englishcn.com)

D: Well, okay. But I do fidget.

Y: You fidget? What does fidgeting have to do with weight? (来源：英语电影下载 http://bt.englishcn.com)

D: Maybe a lot! Researchers at the Mayo Clinic in Minnesota did some experiments to try to figure out why some people gain weight more than others do. (来源：英语学习门户网站EnglishCN.com)

Y: Boy, I can relate to that. Some people can eat whatever they want and they never seem to gain a pound. (来源：英语资料下载 http://download.englishcn.com)

D: In this study, volunteers were given a thousand extra calories a day--about two cheeseburger's worth of extra intake. (来源：英语问答中心 http://ask.englishcn.com)

D: Well anyway, they also wore special devices that recorded how much they moved-- you know, walking up and down steps and whatnot. Everybody gained weight, but some people gained much less than others. The culprit? Fidgeting. (来源：英语学习门户网站EnglishCN.com)

Y: You mean just drumming your fingers or scratching your neck or something? (来源：英语聊天室 http://chat.EnglishCN.com)

D: Any motion takes energy to perform. And little motions like rearranging things on  your desk or stretching your back, if you do them all the time, start to add up. We generally only think of large motions, like exercise, as burning calories. But people   who have the fidgets may be doing a slow, steady burn all day long.
