Regular physical exercise and endurance training are associated with low body weight and low body fat mass. The relationship between exercise and body-weight control is complex and incompletely understood. Regular exercise may decrease energy balance through an increase in energy expenditure or an increase in fat oxidation. It may also contribute to weight loss by modulating nutrient intake. An intriguing question that remains unresolved is whether changes in nutrient intake or body composition secondarily affect spontaneous physical activity. If this were the case, physical activity would represent a major adaptative mechanism for body-weight control.
规律的体育锻炼和耐力训练与低体重和低体脂量相关。运动与体重控制之间的关系复杂且尚未完全明晰。规律运动可能通过增加能量消耗或提高脂肪氧化来降低能量平衡。它还可能通过调节营养摄入来促进体重减轻。一个尚未解决的有趣问题是，营养摄入或身体成分的变化是否会继而影响自发身体活动。如果是这样，身体活动将代表体重控制的一种主要适应性机制。
