When we use our willpower, it robs our brain of energy, or glucose. So, feeding the brain a little sugar when doing a difficult task helps you to fill up your willpower resource. But a new theory contradicts the idea that willpower is limited and can be charged up with sugar.___________________________支持该理论的其他实验发现意志力就像是需要用糖来哄的饥饿的孩子.耗尽意志力之后,耗费了大脑的能量或者葡萄糖.因此,从事艰难任务之前为大脑提供糖类有助于补充意志力. 但是新的理论反对意志力有限的观点,主张可以通过补充糖类来补充意志力.__________________________
