研究：你為什么減肥總是不成功？

　　A riddle: Bob and Bill are roommates and best friends.They eat the same food, have similar jobs and they recently started doing the same workouts together, too. The only difference between them, it seems, is sleep schedules: While Bob gets a solid 7 to 8 hours each night, Bill has an erratic sleep schedule and doesn’t get enough shut-eye.

　　問(wèn)題：Bob和Bill是室友也是最好的朋友。他們每天都吃相同的食物，做相同的工作。最近他們還開始一起做相同的運(yùn)動(dòng)。二人唯一的不同在于睡眠時(shí)間。Bob每晚會(huì)固定睡眠7到8個(gè)小時(shí)，而Bill每天睡眠不規(guī)律，經(jīng)常缺乏休息。

　　Can you guess why their shared exercise and nutrition regimen is successful for Bob and not for Bill?

　　你能猜出來(lái)為什么他們相同的健身和飲食養(yǎng)生計(jì)劃對(duì)Bob見效，而對(duì)Bill沒(méi)用嗎？

　　The only difference is sleep. While Bill and Bob are made up, the results of their circumstances are aren’t. If you want your lifestyle changes to reflect in the way you look , sleep is the key.

　　唯一的差別就是睡眠。盡管Bob和Bill只是兩個(gè)虛構(gòu)人物，但是他們的結(jié)果卻是真實(shí)的。你如果希望改變自己的生活從而帶來(lái)自己外觀的改變，睡眠是關(guān)鍵一步。

　　As The Washington Post pointed out this week, a growing body of research points to the fact that skimping on sleep can lead to weight gain, an increase in injuries and a decrease in testosterone levels, which is often associated with depression and bone density loss.

　　正如華盛頓郵報(bào)本周指出，大量的研究得出一個(gè)結(jié)論，即睡眠不足不僅會(huì)導(dǎo)致體重和受傷害的幾率增加，還會(huì)導(dǎo)致體內(nèi)睪酮水平降低，這些都會(huì)造成抑郁癥以及骨密度下降等不良影響。

　　During deep sleep, the body’s muscles recover, repairing tissue torn during workouts, and the brain creates memories and clears out toxins. Without these processes, you’re exercising and feeding a faulty machine.

　　在深度睡眠狀態(tài)下，身體肌肉會(huì)自動(dòng)修復(fù)鍛煉時(shí)拉傷的組織。大腦會(huì)產(chǎn)生記憶細(xì)胞，排出毒素。缺少這些過(guò)程，你的身體無(wú)論是在鍛煉方面還是飲食方面都會(huì)出故障。

　　“Many people think you build [muscle] in the gym, but you actually build when you sleep,” Chirjeev Sawhney, a personal trainer and fitness manager at a Gold’s Gym in Arlington, told the Post. “It’s when you repair that broken tissue that you get stronger,” Sawhney said.

　　Chirjeev Sawhney是Arlington地區(qū)黃金健身房的私人教練和管理者，他告訴郵報(bào)說(shuō)到：“許多人認(rèn)為鍛煉才可以塑造肌肉，實(shí)際上我們都是在睡眠中塑造的。只經(jīng)歷過(guò)修復(fù)受傷組織過(guò)程，你才會(huì)更強(qiáng)壯。”

　　If the fact that sleep makes your physical fitness more achievable isn’t enough, consider its many other benefits: Quality sleep can make you better at your job. It can extend your lifetime. It’ll make you more likable. It’s time to get the sleep you deserve. You have nothing to lose (except maybe a few pounds).

　　如果睡眠能夠使得健身收獲更大這個(gè)事實(shí)不足以說(shuō)服你，那想想睡眠其他的好處吧。高質(zhì)量的睡眠可以使人們更加高效的工作，更加長(zhǎng)壽，更加迷人。是時(shí)候補(bǔ)補(bǔ)覺了，你已經(jīng)沒(méi)有什么可以損失的了（當(dāng)然可以掉點(diǎn)肥肉）。
