当能量摄入超过能量消耗时，就会发生肥胖。人类通过有目的的运动以及与日常生活相关的姿势和运动的变化消耗能量[称为非运动活动产热（NEAT）]。为了研究NEAT在肥胖中的作用，我们招募了10名瘦的和10名轻度肥胖的久坐不动的志愿者，并在10天内每半秒测量他们的身体姿势和运动。肥胖的人平均每天坐着的时间比瘦的人长2小时。当肥胖个体体重减轻或瘦个体体重增加时，体重分配没有改变，这表明它是生物学决定的。如果肥胖的人采取了瘦的人的NEAT增强行为，他们每天可能会消耗额外的350卡路里（kcal）。
Obesity occurs when energy intake exceeds energy expenditure. Humans expend energy through purposeful exercise and through changes in posture and movement that are associated with the routines of daily life [called non-exercise activity thermogenesis (NEAT)]. To examine NEAT's role in obesity, we recruited 10 lean and 10 mildly obese sedentary volunteers and measured their body postures and movements every half-second for 10 days. Obese individuals were seated, on average, 2 hours longer per day than lean individuals. Posture allocation did not change when the obese individuals lost weight or when lean individuals gained weight, suggesting that it is biologically determined. If obese individuals adopted the NEAT-enhanced behaviors of their lean counterparts, they might expend an additional 350 calories (kcal) per day.
