Dr. Karan Rajan Explains How Nighttime Snacking Harms Your Gut Health

The Gut's Circadian Rhythm

• ⏰ Your body has a circadian clock that dictates energy levels and digestive function, with peak digestive prowess occurring between 11 a.m. and 2 p.m.
• 📉 As the day progresses and the sun sets, digestive function declines, making it harder to digest high-calorie meals consumed closer to bedtime.
