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.
談到減肥，戴維·路德維希(David Ludwig)經(jīng)常會(huì)打這么一個(gè)比方：人體可不是個(gè)烤箱喲。如果是烤箱的話，那我們不管吃何種食物都無關(guān)緊要，而且計(jì)算熱量卡路里數(shù)會(huì)是最有效的減肥方法。

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.
路德維希博士是哈佛大學(xué)公共衛(wèi)生學(xué)院(Harvard T.H. Chan School of Public Health)的肥胖癥專家和營養(yǎng)學(xué)教授，他認(rèn)為，人要是吃錯(cuò)了東西，就會(huì)引發(fā)激素紊亂，陷入“想吃—饑餓—暴飲暴食”的惡性循環(huán)，結(jié)果就是體重開始增加。在其新書《總覺得餓嗎?》(Always Hungry?)中，他提出，如今，肥胖癥的主要原因并非是攝入了過多的熱量本身，而是食用了過量的高升糖指數(shù)食物，如糖、精制谷物和其他經(jīng)加工的碳水化合物等。
