Why I Tell Almost Every Client to Stop Eating Three Hours Before Bed

For years, I didn't think much about when my clients ate, only what and how much. Then I went through my own stretch of broken sleep, a nervous system that wouldn't settle, and mornings where I woke up feeling like I'd been hit by a truck, and I started paying a lot closer attention to timing. One of the simplest shifts I now recommend, almost universally, is this: stop eating at least three hours before bed. While it sounds small, the effects aren’t. And those habits, the simple ones that are benefitting so many things at once, are my favourite ones to help clients shift.

Here's what's actually happening in the body.

When you eat close to bedtime, your body is managing a blood sugar response right when it's supposed to be settling down for the night. That matters a ton in perimenopause, when blood sugar swings hit harder and recover slower than they used to. A lot of the puffiness and grogginess clients describe waking up with often isn’t a sleep problem, but a blood-sugar-at-bedtime problem.

There's a nervous system piece, too. Digestion takes a lot of energy, and it pulls from the same nervous system resources your body needs to downshift into rest. Eat too close to bedtime, and you're asking your body to do two demanding jobs at once: digest food and quiet down. For a nervous system that's already taxed by stress or hormonal change— let alone an overstimulating life — something has to give, and it's usually the depth of your sleep.

Then there's the gut itself. Overnight hours are repair time. Your digestive system benefits from a real break from active digestion to do that maintenance work. Eat too late, and you're more likely to deal with reflux, bloating, or sluggish motility overnight, which shows up the next morning as that tight, puffy midsection so many of my clients mention to me.

And underneath all of it, there's a hormonal conversation happening. Cortisol, melatonin, and insulin are all taking cues from when you eat and when you don't. Eating late and often blurs that signal over time. It’s wise to give your body a clearer sense of when it's time to be active, and when it's time to rest.

This is exactly the kind of habit I mean when I talk about rebuilding from the inside out. It's not a rule you have to follow every single night without exception, it's a small, sustainable shift that impacts blood sugar, your nervous system, your gut, and your sleep, all at once.

If you've been waking up puffy, foggy, or just not yourself, try making this adjustment and see how you feel within two weeks.
