目前肥胖症的流行主要是由促进过量食物摄入和阻碍体育活动的环境造成的。虽然人类已经进化出了很好的生理机制来抵御体重减轻，但当食物充足时，他们只有很弱的生理机制来抵御体重增加。控制份量、食用低脂肪和低能量密度的饮食以及定期的身体活动是预防肥胖的行为，但在当前环境下，采用和保持这些行为变得越来越困难。由于肥胖很难治疗，公共卫生工作需要针对预防。
The current epidemic of obesity is caused largely by an environment that promotes excessive food intake and discourages physical activity. Although humans have evolved excellent physiological mechanisms to defend against body weight loss, they have only weak physiological mechanisms to defend against body weight gain when food is abundant. Control of portion size, consumption of a diet low in fat and energy density, and regular physical activity are behaviors that protect against obesity, but it is becoming difficult to adopt and maintain these behaviors in the current environment. Because obesity is difficult to treat, public health efforts need to be directed toward prevention.
