Consider the following diets: Atkins (all fat and no carbohydrates); traditional Japanese (all carbohydrates and little fat); and Ornish (even less fat and carbohydrates with lots of fiber). All three help to maintain, and in some cases even improve, metabolic health, because the liver has to deal with only one energy source at a time.
我们来看一下以下食谱：阿特金斯饮食（Atkins，戒除糖分，脂肪随意）；传统日本饮食（糖分随意，极少量脂肪）；以及奥尼什饮食（Ornish，大量纤维，更少脂肪和糖分）。这三种食谱都有助于维持（有时甚至能改善）代谢健康，因为肝脏每次只需处理一种能源。
