Bad sleep, big cravings: why the binge urge hits the next day
Five hours of sleep and by mid-afternoon you want to eat everything in the house. It's easy to read that as a lack of discipline. Most of it is chemistry.
After a short night, ghrelin (the hormone that says "eat now") runs higher and leptin (the one that says "you've had enough") runs lower. On top of that, the part of the brain that normally stops an impulse before you act on it is the part hit hardest by missing sleep. Stronger urge, weaker brakes.
The catch is timing. The effect usually shows up the day after the bad night, so people rarely connect the two. If an urge seems to come out of nowhere, look back over the last 24 to 36 hours of sleep first. The full explanation is in how sleep debt sets up the next binge.

Slept five hours and now you want to eat everything? That is not a willpower problem.
A short night turns your hunger signal up and your fullness signal down.
And the part of your brain that stops an urge is the part that got the least rest.
It often hits the next afternoon, so people never connect it to the bad night.
When it shows up, tap the green button.
