The habit loop: keep the cue, keep the reward, change the middle
June 9, 2026 · 読了6分
A three-part structure
Charles Duhigg in The Power of Habit and James Clear in Atomic Habits describe habits with the same structure, differing only in how finely they slice it. Duhigg uses three parts: cue, routine, reward. Clear splits it into four: cue, craving, response, reward.
What they share matters more than where they differ. Both say the behaviour in the middle does not stand on its own. It is held in place by what comes before it and what comes after it.
Worth being clear about what this is: a descriptive model that many people find useful for thinking about their own behaviour. It is not a law, it simplifies a great deal, and it should not be read as a diagnosis.
Why deleting a habit is hard
The most common way to drop a habit is to decide not to do it anymore. This fails frequently, and the reason is right there in the structure.
When you decide to stop ordering food late at night, you have not touched the cue. 1am still arrives. The bed is still there. The hollow feeling at the end of a long day still shows up on schedule.
You have also not touched the reward. What ordering food gives you — a few minutes of not thinking about anything else, the sense of handing yourself something, one small action with a clear result on a day where everything else stayed unfinished — is still something you want.
The only thing you removed is the behaviour in the middle. But the cue still fires and the reward is still expected, so the empty middle generates pressure. That pressure usually wins, and it usually wins on the night you are most tired.
The other approach: substitute, don't subtract
Duhigg and Clear both point the same direction: keep the cue, keep the reward, and swap only the middle for a different behaviour that delivers something close to the same reward.
Simple to state, harder in practice, because the substitute has to genuinely deliver that reward. Drinking a glass of water does not replace ordering food, because the reward of ordering food was never liquid entering a body.
To work, the new behaviour has to match what the reward actually was. For late-night ordering, the reward usually includes:
- A run of small choices, each with immediate feedback
- The feeling of handing yourself something after a long day
- A stretch of time where thinking is not required
- An anticipation with a defined endpoint
A substitute missing three of those four will not survive a week.
Where Table for None sits
This product is a substitute behaviour, and it was designed against that list rather than by vibe.
The cue stays: same phone, same hour, same bed. We do not ask you to change your circumstances, because changing circumstances is the hardest part and where most plans quietly die.
The middle changes: you open this app instead of that one.
The reward keeps most of its old shape. There is still a menu. There are still choices. The price still moves when you add toppings. The countdown still runs and the rider still crawls across the map. There is still a clean endpoint: the order closes, and the money you did not spend gets added to a number.
What you lose is the food. What you do not lose is the money.
This is not magic
Swapping the middle does not erase the cue and does not make the craving vanish. There will be nights when you open this app, finish, and then open the other one anyway. That is ordinary and requires no follow-up.
The habit loop is also only a model. Not every repeated behaviour fits neatly into three boxes, and some things sit entirely outside what an app can reach.
But if you have tried the delete approach and watched it not work, substitution is at least a different thing to try. It is cheaper, and it does not require you to become a different person before you are allowed to start.
You do not need to want less. You need somewhere else to put the wanting.
