Better sleep starts at dinner time.
I’m a sucker for “the gray hair special”. This means that I like to eat dinner early. Like, really early. Sometimes Tim and I make it a challenge to be done eating by 5:30 pm. I know, living life on the edge.
I don’t just do this because I’m secretly an old lady. Yes, that’s part of it, but more importantly, my body feels and functions best when I’m consistent with my meals and my bedtime. And if you know anything about me….boy, do I love bedtime. The earlier the better.
So, last week’s message was all about making sure you’re eating enough food to fuel your training. This week, it’s about how to fit those meals in to best support your rest and recovery.
Try to finish your last meal about 3 hours before bed. Yes, really.
Here’s why:
1. Your metabolism runs on a clock (literally). Your body follows a circadian rhythm, and your metabolism is part of that.
At night:
Insulin sensitivity drops (you don’t handle carbs as efficiently)
Glucose tolerance decreases (blood sugar stays elevated longer)
So the same meal eaten at 9pm can lead to a bigger blood sugar spike than if you ate it at 6pm.
2. Digestion and sleep don’t exactly get along. Falling asleep isn’t just about being tired. Your body is trying to shift into a lower-energy, recovery-focused state.
A full meal too close to bed can:
Keep your core body temperature elevated (and body temp needs to drop in order to sleep soundly)
Increase chances of reflux or indigestion
Keep your body busy digesting instead of fully powering down
The result? More tossing, turning, and less restful sleep.
3. When this happens, your hormones and recovery take a subtle hit. Overnight is when a lot of your recovery takes place:
Growth hormone supports muscle repair
Your body leans more on fat as a fuel source
Eating late can keep insulin elevated, which messes with fat burning overnight and may interfere with some of your recovery processes. Research has linked consistent late-night eating with poorer blood sugar control and increased risk of metabolic issues. Interestingly, some studies show that people who eat earlier in the day lose more weight, even when calories are the same.
So, why “3 hours”?
It’s not magic - it’s practical. This window gives your body time to digest most of your meal, bring your blood sugar and insulin levels back down, and shift into a true rest-and-recover mode.
What to do with this info:
Aim to finish dinner ~3 hours before bed
If you need a snack later, focus on protein
Try to keep your heaviest meals earlier in the day, when possible
As always, this isn’t all-or-nothing. Late workout? Busy schedule? General life chaos? You’re fine. Total daily caloric intake still matters most.
But if you’re aiming for:
Better sleep
Improved recovery
Body recomposition
…this is one of those small habits that can quietly make a difference.
Eat up. Eat early.
