Human caloric expenditure for physical activity in non-athletes is much lower than physically active populations. The y axis is the ratio of Activity Energy Expenditure (AEE) /Resting Energy Expenditure (REE). AEE = free-living energy expenditure – (diet-induced energy expenditure + REE). Data are presented for various human groups (non-athletes living in developed nations, military trainees, individuals from rural areas engaged in high levels of physical activity, and athletes in training) on the x axis. Each bar is a single subject. Non-athletes in developed nations have AEE/REE ratio of = ~0.5, which is equivalent to PAL of ~1.67). [Reproduced with permission from (225)].
