Timing our meals can fend off diseases caused by bad genes or bad diet. Everything in our body is programmed to run on a 24-hour or circadian timetable that repeats every day. Nearly a dozen different genes work together to produce this 24-hour circadian cycle.
These clocks are present in all of our organs, tissues and even in every cell. These internal clocks tell us when to sleep, eat, be physically active and fight diseases. As long as this internal timing system work well and we obey them, we stay healthy.
