The 'obesity paradox' refers to observations that run counter to the thesis that normal weight (BMI 18.5-24.9 g/m(2)) provides the lowest mortality and higher weight is associated with greater mortality. We argue that the weight of lowest mortality is influenced by aging and chronic disease, with mortality advantage extending into the overweight and even class I obese ranges under some circumstances. A focus on quality nutrition, physical activity, fitness, and maintaining function in these weight ranges may be preferable to a focus on intentional weight loss, which has uncertain effects. The 'obesity paradox' is no 'paradox' if one defines and interprets 'ideal' weight appropriately.
“肥胖悖论”指的是一些与正常体重（体重指数18.5 - 24.9 g/m²）死亡率最低且体重越高死亡率越高这一论点相悖的观察结果。我们认为，最低死亡率的体重受到衰老和慢性病的影响，在某些情况下，死亡率优势会延伸到超重甚至I级肥胖范围。关注这些体重范围内的优质营养、体育活动、健康状况以及维持身体功能，可能比关注效果不确定的刻意减肥更为可取。如果能恰当地定义和解释“理想”体重，“肥胖悖论”就并非“悖论”。
