许多小规模的研究已经确定了体育活动在预防肥胖中的作用。这就是能量平衡方程式中的“能量消耗”方面。虽然每天大约半小时的中等强度的体力活动对于心血管健康和疾病预防是必要的，但预防肥胖和减肥所需的体力活动量大约是每天60-90分钟。仅通过休闲时间体育活动(LTPA)很难实现这一数量的体育活动，在积极的交通、职业活动和家庭环境中需要额外的能量消耗。对24小时能量消耗的模拟表明，为了减肥和预防肥胖，“积极生活”的需要，也就是超过长期摄入量的能量消耗。这对中国等发展中国家的后果是，需要重点防止因城市化、工业化和对机动车的依赖而导致的能源支出下降。如果要将这些作为预防肥胖的策略认真对待，那么它们将在发展中国家构成政策挑战。
Much small-scale research has identified the role of physical activity in obesity prevention. This is the 'energy expenditure' side of the energy balance equation. Although around half an hour of daily moderate-intensity physical activity is required for cardiovascular health and disease prevention, the quantum of physical activity required for obesity prevention and weight loss is around 60-90 minutes per day. This amount of physical activity is difficult to achieve through leisure time physical activity (LTPA) alone, and additional energy expenditure is needed in the domains of active transport, occupation activity and in domestic settings. Modeling of 24-hour energy expenditures demonstrate the need for 'active living', namely energy expenditure over and above that due to LTPA, for weight loss and obesity prevention. The consequences of this for developing countries such as China are the need to focus on preventing the declines in energy expenditure attributable to urbanization, industrialization, and motor vehicle dependence. These will pose policy challenges in the developing world, if they are to be taken seriously as obesity prevention strategies.
