许多人都把中年发福归咎于新陈代谢变慢,然而新研究发现,中年人的新陈代谢速度和年轻人无异,60岁后新陈代谢才开始减速。也许,中年发福只是吃得太多,动得太少。
Middle-aged1 spread cannot be blamed on a waning2 metabolism3, according to an unprecedented4 analysis of the body's energy use.
一项史无前例的新陈代谢研究指出,不能将中年发福归咎于新陈代谢变慢。
The study, of 6,400 people, from eight days old up to age 95, in 29 countries, suggests the metabolism remains5 "rock solid" throughout mid-life.
这项涵盖了29个国家6400人的研究显示,人在中年时期的新陈代谢一直“稳如磐石”。研究对象中,最小的刚出生8天,最高龄的已经95岁。
It peaks at the age of one, is stable from 20 to 60 and then inexorably declines.
新陈代谢在1岁时达到顶峰,20岁到60岁期间保持稳定水平,60岁后开始不可阻挡地变慢。
The study, published in the journal Science, found four phases of metabolic6 life:
这项发表在《科学》期刊上的研究发现,人的一生中新陈代谢可分为四个阶段:
1. birth to age one, when the metabolism shifts from being the same as the mother's to a lifetime high 50% above that of adults
第一阶段:出生到1岁。新陈代谢速度最初和母亲一致,后来达到一生中的最高水平,比成人高出50%。
2. a gentle slowdown until the age of 20, with no spike7 during all the changes of puberty
第二阶段:1岁到20岁。新陈代谢逐渐变慢,
