The 10:40 problem
It's 10:40 at night.
The kitchen light is off. And you know exactly where the packet is.
You aren't hungry. You know you aren't hungry.
You've known it, at this hour, for years.
Tomorrow you'll be strict again. And within three days you'll be right back here. Let me tell you why — and how it ends.
The reason isn't hunger, and it isn't weakness. It's a loop.
A cue. A reach. A reward. On repeat.
Here's the machinery.
Something fires the cue — the time, the dark kitchen, the silence, the exhaustion.
The reach follows before you've decided anything. Then relief, for a few minutes. That's the reward.
Do that a few hundred times and it stops being a choice. It becomes automatic — cue-triggered, running with almost no conscious control (Wood & Rünger, 2016).
You're not deciding to eat at night. A learned program is running, and you're watching it happen.
Which is oddly good news — because anything learned can be un-learned.
Two things feed the night. Both are fixable.
First: tiredness. Short sleep doesn't just make you tired — it measurably makes you eat more, hundreds of calories more, mostly late (Covassin et al., 2022). Fix the sleep and the night gets quieter on its own.
Second: the feeling. Night is when the day's unspoken stuff surfaces, and food is the nearest comfort. That's an emotional pattern, not a hunger one.
So you don't attack the snack. You change what the cue leads to.
The reach gets a new destination — a different response, practised until it runs on its own, in the chair and then in a few minutes a day.
And the deepest fix is stranger, and simpler, than any of that.
In practice
Why night is different.
Four things collapse after nine at night, all at once.
Your decisions are spent. A day of choices leaves the part of the brain that says ‘not now' running on empty.
The witnesses go home. At the office you'd never. Alone in a dark kitchen, nobody's watching — including you.
The day surfaces. Whatever you didn't feel at two in the afternoon arrives at eleven, when there's finally silence for it.
Tired reads as hungry. The sleep-deprived brain misfiles its own exhaustion as a need for fuel.
That's why you can be flawless all day and undone in an hour. It isn't weakness arriving at night. It's four defences leaving.
So you rebuild the evening around that truth.
Why the packet, and never the fruit.
Notice something. At 10:40 you never reach for an apple.
That tells you everything. If it were hunger, fruit would do. The body isn't asking for fuel. It's asking for a specific effect: the sugar, the fat, the crunch — the fastest chemical calm the cupboard offers.
That's the fingerprint of emotional regulation, not appetite. The reach is doing a job: softening the day, filling the silence, closing something open.
So the honest question at 10:40 was never ‘how do I stop eating?' It's ‘what is this eating doing for me?'
Answer that, and give the job to something else, and the packet becomes what it always was — just a packet.
Which is exactly what the rewrite is built to do.
Rewriting the 10:40 script.
Eat a real dinner. Enough, with protein. A ‘light dinner' is the most reliable way to guarantee the 10:40 reach.
Give the cue a new destination. The hour will still come. So the response is fixed in advance: a hot drink, five minutes of the breath practice, then bed. Same thing, every night. The cue fires; something else runs.
Close the kitchen. Light off, door shut, a small ritual that tells the automatic mind the day's eating is done.
Go to bed earlier than feels necessary. Most night eating happens in the hour you were too tired to be awake for.
The first three nights are the hard ones. Around the second month it stops being a thing you do and becomes a thing that simply is.
The test isn't resisting the packet. It's the night you notice it's there, and don't care.
That night comes. And it arrives earlier than you'd think.
You change what the cupboard means.
Right now the cupboard means comfort. Escape. The one reliable thing at the end of a hard day.
That meaning was learned. And meaning can be re-written.
When the packet stops being ‘my reward’ and becomes just food in a cupboard, the pull isn't resisted — it's gone.
That's the test, by the way. Not whether you can resist it at 10:40.
Whether, one night, you notice it's there — and simply don't care.

Straight answers
Questions people ask.
Why do I eat at night when I'm not hungry?
Because a learned cue-reward loop is running, not because you are hungry. A trigger such as the time, the dark kitchen, silence or tiredness fires an automatic reach that once brought relief. Repeated enough, it runs with almost no conscious control.
How do I stop eating at night?
Address the two things feeding it: tiredness, since short sleep measurably increases late-night eating, and the emotion the food is soothing. Then change what the cue leads to by practising a different response, rather than trying to resist the snack by willpower.
Is night eating a sign of a disorder?
Persistent, distressing night eating can be part of night eating syndrome or binge eating disorder, which need specialist assessment. Ordinary learned late-night snacking is common and responds to changing the cue, the sleep and the emotion behind it. If it feels out of control, seek professional help.
If this landed
A fit we both have to see.
I take on a few people a year.
Not a programme you join. A fit we both have to see. If you want to be considered, tell me three things: what you have tried and why it did not hold, why now and not last year, and what will be true in a year that is not true today.
I read every note myself, and reply to every one, even when the answer is no. Either way, I wish you well.
A few honest questions, and it comes straight to me.
