The circadian rhythm controls many physiological functions, such as feeding, motor activity, endocrine secretion and autonomic nerve. Regular feeding pattern can entrain the peripheral circadian clock, whereas peripheral clock systems can control the absorption distribution, metabolism and excretion of nutrients, suggesting mutual interactions between circadian clocks and nutrition/food. The interactions were so-called by "chrono-nutrition", and bigger meals for breakfast were good for entrainment of peripheral clock and protection of obesity. Similar to chrono-nutrition the timing of exercise ("chrono-exercise") is important for both entrainment signals and energy expenditure. Evening exercise and/or feeding then exercise was good timing exercise for protection of obesity. Taken all, it is suggested that timing of feeding and exercise is now one of key factors for metabolic syndrome.
