What is Circadian Rhythm Fasting?

The reason you’re energized to get out of bed in the morning, but tired enough to crawl back under the sheets again at the end of the day? Your natural 24-hour body clock, also known as your circadian rhythm. But this internal cycle isn’t just responsible for waking up and winding down—it also has a major effect on a ton of your body’s other natural processes, from digestion to blood sugar regulation. In fact, aligning your eating habits to your circadian rhythm might be beneficial for improving your body composition.
For a lot of people, this practice can be effective through circadian rhythm fasting, says sports performance dietitian Umo Callins, RD, CPT. The goal is to consume a large chunk of your calories when your body is most metabolically efficient and your metabolism works at its fastest: when you wake up. On the contrary, at night, generally most people’s bodies (and metabolisms) are physically slowing down, says Jennifer McDaniel, RD, MS, a registered dietitian.
