According to the latest reports issued by the Centers for Disease Control and Prevention(CDC), two out of three Americans are over-weight, and one in three is obese.The majority of these individuals would very much prefer to weight less. Overweight individuals not only grapple with an increased susceptibility to heart disease and diabetes, but they contend with the self-esteem-crushing consequences of being heavy in a society in which thin is in. And yet,despite an abundance of diet books and plans, and a very real and powerful desire to be slim, relatively few people who set out to lose weight actually manage to lost it and keep it off long-term. We're not getting any thinner, and our skinny jeans are still waiting for us in our closets.
美国疾病预防控制中心（CDC）的最新报告指出，每三个美国人中就有两个超重，每三人中就有一人肥胖。大多数人都倾向于希望减轻体重。超重的人不仅更容易患心脏病和糖尿病，并且在一个以瘦为美的社会中，自尊还会受到伤害。然而，尽管有了大量的节食书籍并制定计划，有非常真实和强烈的愿望去减肥，相对来说，那些想减肥的的人却很少能够成功，并且保持下去。我们没有变瘦，我们的紧身牛仔裤还躺在衣柜里等着我们。
