Recommended Last Meal Time
Aim to finish eating at least 3 hours before sleep.
The Power of Chrononutrition
Chrononutrition is a field of science that studies the relationship between our internal biological clocks (circadian rhythms) and nutrition. Our bodies are programmed to perform certain functions at specific times of the day. For example, our digestive system is most active during the day and slows down at night to prepare for rest and repair.
Eating late at night can disrupt this natural rhythm. When you eat close to bedtime, your body has to focus on digestion instead of restorative processes that happen during sleep. This can lead to a variety of issues, including poor sleep quality, acid reflux, and potential weight gain over time as your metabolism is less efficient at night.
Benefits of an Early Meal Cutoff:
- Improved Sleep Quality: Allows your body to focus on rest and cellular repair, not digestion.
- Better Digestion: Reduces the risk of acid reflux and indigestion.
- Enhanced Metabolic Health: May improve insulin sensitivity and support weight management.
- Increased Autophagy: A longer fasting window overnight promotes cellular cleanup and renewal.
Note: This is a general guideline. Individual needs may vary based on lifestyle, medical conditions, and work schedules (e.g., shift work). Listen to your body and consult a healthcare professional for personalized advice.
