But the kind of food you eat and when you eat it does influence how hungry you feel (and thus your self-control), and whether you use up the calories you eat or turn them into fat even as you still feel hungry. (Sugar is the main culprit, as Robert Lustig, the author of Fat Chance, has argued.)
卡路里确实有用；能量的物理学在人体中也起着作用。但吃什么和何时吃确实影响着你的饥饿感（从而影响你的自控力），以及你吃下去的卡路里是否会转化为脂肪（即使你仍有饥饿感）。（糖果是主要罪魁，《肥胖有望》（Fat Chance）作者罗伯特·卢斯蒂格（Robert Lustig）如是说。）
