Obesity is associated with multiple negative health consequences and current weight management guidelines recommend all obese persons to lose weight. However, recent evidence suggests that not all obese persons are negatively affected by their weight and that weight loss does not necessarily always improve health. The purpose of this review is not to trivialize the significant health risks associated with obesity, but to discuss subpopulations of obese people who are not adversely affected, or may even benefit from higher adiposity, and in who weight loss per se may not always be the most appropriate recommendation. More specifically, this review will take a devil's advocate position when discussing the consequences of obesity and weight loss for adults with established cardiovascular disease and type 2 diabetes, weight cyclers, metabolically healthy obese adults, youth, older adults and obese individuals who are highly fit.
肥胖与多种负面健康后果相关,当前的体重管理指南建议所有肥胖者减重。然而,最近的证据表明,并非所有肥胖者都会因其体重受到负面影响,而且体重减轻并不一定总能改善健康状况。本综述的目的不是轻视与肥胖相关的重大健康风险,而是讨论那些未受不利影响、甚至可能因较高肥胖程度而受益的肥胖亚人群,以及那些体重减轻本身可能并非最合适建议的人群。更具体地说,在讨论肥胖和体重减轻对已确诊心血管疾病和2型糖尿病的成年人、体重反复波动者、代谢健康的肥胖成年人、年轻人、老年人以及身体状况极佳的肥胖个体的影响时,本综述将采取唱反调的立场。
