If you're struggling with sleep quality while researching GLP-1s like tirzepatide or retatrutide, here's something that helped me and many others:
Push your last meal 3-4 hours before bedtime.
Why This Works (The Science Made Simple)
GLP-1 receptor agonists work partly by slowing down gastric emptying - basically, your stomach takes longer to process and move food into your intestines. This is actually one of the mechanisms that helps with satiety and weight management.
But here's the problem: when you eat close to bedtime while on these peptides, your digestive system is still working overtime while you're trying to sleep. Your body is:
- Actively digesting food (which requires energy and blood flow)
- Dealing with potential acid reflux from food sitting in your stomach longer
- Experiencing blood sugar fluctuations as nutrients slowly absorb
- Staying in a more "active" metabolic state instead of rest mode
All of this can seriously impact your deep sleep - the restorative stage where your body does most of its repair work and growth hormone release happens.
The Fix
Stop eating 3-4 hours before bed. Give your stomach time to empty and your body time to shift into proper rest mode.
You'll likely notice:
- Falling asleep faster
- Better deep sleep quality (check your sleep tracker if you have one)
- Less middle-of-the-night wake-ups
- Reduced morning grogginess
This one simple timing adjustment has been a game-changer for sleep quality while researching these compounds. Your body will thank you.
