Keep dinner light to sleep better and wake fresh
Why it matters
A late and heavy dinner raises blood sugar levels and interferes with melatonin production, the hormone that signals sleep. Eating close to bedtime keeps your body in an active state instead of shifting into recovery mode, leading to poorer sleep quality and morning sluggishness. Having a light dinner at least 3 hours before bed helps lower blood sugar spikes, supports melatonin release, and makes it easier to fall asleep
How to do it
- Eat dinner at least 3 hours before bedtime
- Fill only ¼ of your plate with carbohydrates
- Focus on protein, fiber, and vegetables
Science snap
Studies show that having a light dinner 3 hours before bedtime can reduce nighttime blood glucose levels and improve sleep quality

Mechanism & Key fact
Late-night meals raise insulin levels and prevent your body’s natural drop in core temperature, making it harder to fall asleep. Eating dinner at least 3 hours before bed can lower nighttime blood glucose levels by 10–15%, support melatonin release, and shorten the time it takes to fall asleep. Research shows that digestion and metabolism stay active for several hours after eating, which can delay the body’s transition into deep sleep phases. A lighter dinner also reduces gastrointestinal discomfort and minimizes nighttime awakenings. Combined, these factors promote better sleep architecture, leaving you feeling more refreshed and alert the next day
