How are overall energy intake and expenditure related
penditure are especially large when days with high energy expenditure are alternated with quieter intervals. For example, military cadets did not show an increase in energy intake on days with a higher energy expenditure when they joined a drill competition. The corresponding increase in energy intake occurred about 2 days later [3].
