Obesity develops as an interaction of genetic disposition and environmental factors (nutrition, physical activity). Mental disturbances are considered to be a consequence but not the cause of overweight. For long term weight maintenance three factors are important: normalization of fat intake, flexible control of food intake and an increase in physical activity.
肥胖是遗传倾向与环境因素（营养、身体活动）相互作用的结果。精神障碍被认为是超重的后果而非原因。长期维持体重，三个因素很重要：脂肪摄入正常化、灵活控制食物摄入量以及增加身体活动。
