Does that mean that thinking harder is a simple route to losing weight?

|20a,3qI,4HrGR^sA

这是否意味着冥思苦想是一条简单的减肥之路?

QPaMIORo,M3ek.g

Well, when the body is at rest, we know that the brain uses up a startling 20% to 25% of the body's overall energy.

0evAWuEkV1]Gt

嗯,我们知道,当身体处于休息状态时,大脑会惊人地消耗掉身体总能量的20%到25%(X~ss)_#eHAAFZ0f|

4.;dMG!j%~^*=

This level of utilization actually makes the brain the most energy-expensive organ in the body,

&bz|p^x3g]

这种利用程度实际上使大脑成为身体中能量消耗最高的器官,

and yet it makes up only 2% of the body's weight overall.

8#d+Q9.DkyzJk*

然而它只占身体总重量的2%qtRsnzhTNY3]B]

AZ*sR2~+Hie1*2.k

So the more we put this organ to work, the more calories we'll burn?

#y2zH2+!ztr

那么我们让这个器官工作得越多,燃烧的卡路里就会越多吗?

g+a=~CN@iGpBUpoWp

Technically, the answer is yes, for cognitively difficult tasks.

^9,*IG(Bno%P,2I9

严格来说,对于难度高的认知活动,答案是肯定的ij;8b~lThWe|&u+g

But generally, it could be described as something that the brain cannot solve easily using previously learned routines, or tasks that change the conditions continuously.

Y@kyvmJnLF#

但一般来说,它可以被描述为“大脑依靠先前习得的常规模式无法轻易解决的任务,或是不断改变情形的任务”Ic1htXwqJ~j~BGOE8_

然而,深度思考并不能燃尽吃甜食获得的热量r#WOMc@1#fwIYIJ=_m

PdUoeb^h_+&CPcb7j6

Because in relation to the brain s huge overall energy usage, which is devoted to a multitude of tasks, the energy required just to think harder is actually comparatively tiny.

XluE3o5UVCNF9~gx-ric

因为相比大脑用于众多活动消耗的巨大总能量,只进行冥思苦想所需的能量实际上相对极少i^9CMK,g570@y

The brain is able to allocate blood (and thus energy) to particular regions that are being active at that point.

v[Ci&=e;OXq@+Kciqh

大脑能够将血液(以及其携带的能量)分配到某刻处于活跃状态的特定区域L.WwGdxzeb

re+Jt-a2|3)~xZiQMd

But the overall energy availability in the brain is thought to be constant.

K@I[LBBXU@=Aa0uTDp

但大脑中可利用的总能量被认为是恒定的Y&mL()j.=EV1=BaG1T1

Fl&u2k0j[WwVmfjd~V

So, while there might be significant increases in energy use at localized regions of the brain when we perform difficult cognitive tasks,

Evxz^HJgg3F1H~*]

所以,尽管当我们进行困难的认知活动时,大脑局部区域的能量消耗可能会显著增加,

822,YyT1N+duO@(.fo

when it comes to the whole brain's energy budget overall, these activities don't significantly alter it.

W(2+[H+yn!q6(s7&7EG

但当涉及到整个大脑的能量总收支时,这些活动不会对其有太大改变l1!RH=6|0g
