The circadian rhythm, of course, most people know about him, believe that it's related to the this master clock in your brain. But what most people don't realize is that every single one of your cells in your body have a clock within it that's unrelated to the super chiasmatic nucleus. And unlike light and day, which triggers that master clock, it appears that food is the most important trigger for this other clock and all the rest of your cells.
