Chapter3 Too tired too resist:why self-control is like a muscle
自控力和我们的肌肉一样，用久了就会累，一般来说，早上我们的自控力是最强的，随着他的消耗增加，他的量也就越少。
Just like a tired runner's leg can give out, the brain seems to run out of the strength to keep going.
所以我们要尽可能趁他还多的时候做些难度较大的事情。
那为什么会出现这种现象？
Self-control, one of the most energy-expensive tasks the brain performs.
因为他是最耗脑力的活动之一。
所以我们要保证大脑有充足的能量，但并不是说要多吃糖等高热量的东西，而是要吃一些能持续提供能量的东西，让你的血糖保持在一个相对稳定的值。这些食物通常是：lean proteins, nuts and beans, high-fiber grains and cereals, and most fruits and vegetables.其实就是现在倡导的健康饮食，高蛋白质，坚果，杂粮谷物，水果，蔬菜等。原来健康的吃不仅能保持好身材，还能保证自控的大脑。
Basically, food that looks like its natural state and doesn't have a ton of added sugar, fat and chemicals.
