"It’s not you, it’s your schedule." Does it sound like magic? It’s not. We’ve all heard of circadian rhythms—those biological processes that give us jet lag and make us night owls or early birds. But few of us know just how profoundly these diurnal patterns affect our overall health.

Bad habits like skipping meals, squeezing in workouts when it’s convenient, working late into the night to maximize productivity and then trying to "catch up" on sleep during the weekend disrupt our natural cycles. A growing body of research on chronobiology reveals just how sensitive the human body is to these rhythms all the way down to the genetic level. Our "clock genes" control more than we realize, and small changes can make the difference between battling our bodies, and effortlessly managing weight, sleep, stress, inflammation, and more.
