Why Do I Crave Sugar at Night? Stress, Sleep and the 9pm Snack
You get through the day on tea and good intentions. Dinner’s done, the house goes quiet, and twenty minutes later you’re standing at the pantry looking at the biscuits. You weren’t hungry at six.
It’s one of the most common eating patterns going, and it’s often got less to do with willpower than people think.
Stress can change what you want to eat
Harvard Health explains that a short burst of stress can switch your appetite off for a while. If the stress hangs around, cortisol (the stress hormone) can push appetite and the urge to eat up. In an article from 2012, Harvard pointed out that many studies, mostly in animals, found distress increases the intake of high-fat, high-sugar foods. It also said fatty and sugary foods may quieten the parts of the brain that process stress, so a craving can partly be your body looking for relief.
The same article mentions British researchers who found that people whose cortisol rose the most in a lab stress test were more likely to snack when daily hassles piled up.
Evening is often the first time the day actually stops. That might be one reason the craving shows up then, when there’s nothing left to distract you from how the day went.
Tired bodies ask for more
Sleep seems to matter too. One study in healthy young men linked short sleep with lower leptin, higher ghrelin and more hunger and appetite. Another found that a single night of sleep deprivation raised ghrelin and hunger in healthy men. Leptin and ghrelin are the hormones involved in feeling full and feeling hungry.
It isn’t settled. Both studies were in men, and other researchers have questioned whether the hormones fully explain the extra eating. Harvard also points out that stressed people tend to sleep less, exercise less and drink more alcohol, so stress and tiredness often turn up together.
The habit part
For a lot of people the 9pm snack turns into a loop. Tough day, quiet house, couch, snack, a few minutes of relief. Do that for a few weeks and the couch itself can start the whole thing off, before any real craving has shown up.
That matters, because a loop is hard to beat by using more willpower each night. It’s often easier to work on the pattern itself.
That’s where MindShift Mentors comes in. They’re the team behind Cuisine Seeker, and their Break the Habit program is a guided audio program designed to help you work on the pattern underneath a habit, not just the willpower sitting on top of it. There’s a 7-night free trial and you don’t need a credit card. Results vary from person to person, and it’s designed to sit alongside professional care, not replace it.
Things worth trying tonight
- Plan the snack. Decide what you’ll have, put it on a plate, sit down and enjoy it. A planned snack tends to feel different to one eaten standing at the pantry.
- Give it ten minutes. Harvard says meditation may help people pause before impulsive eating. Set a timer, make a herbal tea, and see if the craving’s still there when it goes off.
- Walk after dinner. Harvard notes that low-intensity exercise seems to lower cortisol. A slow lap of the block counts.
- Try an earlier night. A few early nights costs nothing, and it’s an easy way to see whether tiredness is part of your pattern.
- Make dinner a proper meal. Some people find the evening pull is weaker when dinner is a full meal rather than something grabbed.
If eating feels out of your control, or the cravings come with other changes in your health, talk to your GP or a dietitian. This article is general information only.
