David Ludwig often uses an analogy when he talks about weight loss: Human beings are not toaster ovens. If we were, then the types of calories we consumed would not matter,and calorie counting would be the most effective way to lose weight.

谈到减肥，戴维·路德维希(David Ludwig)经常会打这么一个比方：人体可不是个烤箱哟。如果是烤箱的话，那我们不管吃何种食物都无关紧要，而且计算热量卡路里数会是最有效的减肥方法。

Dr. Ludwig, an obesity expert and professor of nutrition at the Harvard T.H. Chan School of Public Health, argues that weight gain begins when people eat the wrong types of food, which throws their hormones out of whack and sets off a cycle of cravings, hunger and bingeing. In his new book,“Always Hungry?” he argues that the primary driver of obesity today is not an excess of calories per se, but an excess of high glycemic foods like sugar, refined grains and other processed carbohydrates.

路德维希博士是哈佛大学公共卫生学院(Harvard T.H. Chan School of Public Health)的肥胖症专家和营养学教授，他认为，人要是吃错了东西，就会引发激素紊乱，陷入“想吃—饥饿—暴饮暴食”的恶性循环，结果就是体重开始增加。在其新书《总觉得饿吗?》(Always Hungry?)中，他提出，如今，肥胖症的主要原因并非是摄入了过多的热量本身，而是食用了过量的高升糖指数食物，如糖、精制谷物和其他经加工的碳水化合物等。
