Late meals, sleep and recovery
Short answer: A large meal within two to three hours of bed keeps your body digesting while you sleep. For many people that raises overnight heart rate and lowers HRV, and it shows up as a lower recovery score. Finishing dinner two to three hours before bed is a simple experiment worth trying.
Why timing matters
Digestion increases metabolic rate and blood flow to the gut. If that’s still going on when you fall asleep, your heart works harder overnight. That usually means a higher sleeping heart rate and lower HRV, the two biggest inputs to most recovery scores.
What you eat matters too. In one study, diets higher in saturated fat and lower in fibre were linked to lighter, more disrupted sleep (St-Onge et al., 2016).
How to test it yourself
- Tag Late meal on nights you eat within about 2–3 hours of bed.
- Keep everything else roughly normal for two to three weeks.
- Compare next-morning recovery and sleep on tagged and untagged days.
Late meals often happen on social evenings, alongside alcohol. Tag both, so you can tell them apart over time.

Is a small snack before bed fine?
For most people a light snack is fine. It's large, rich or very late meals that tend to show up in overnight heart rate.
How late is a late meal?
There's no strict definition. A practical goal is to finish your main meal 2–3 hours before bed, and tag anything later than that as a late meal.
