You’ve just eaten. You’re not hungry. And yet you’re standing in front of the fridge, hand on the door, not entirely sure why you’re there.
If that sounds familiar, you’re not lacking willpower. You’re not broken. Your brain is simply doing exactly what it was trained to do.
Neuroscientist and psychiatrist Dr Judson Brewer explores this in his book The Hunger Habit, and what he finds is both surprising and deeply practical. Here are the key ideas, and what they might mean for you.
Your Brain Isn’t Asking If You’re Hungry
Every habit including eating follows a simple three-part loop: trigger, behaviour, reward. Stress arrives (trigger), you reach for something to eat (behaviour), and the discomfort temporarily eases (reward). The brain registers this as a success and files it away for next time.
Over time, this loop becomes automatic. The brain stops asking “am I hungry?” and starts asking “what worked last time I felt like this?” The answer, more often than not, is food.
We Eat to Solve Feelings, Not Hunger
Most of the time, emotional eating isn’t about food at all. It’s an attempt to manage feelings we’d rather not sit with things like:
- Stress or overwhelm
- Boredom or restlessness
- Fatigue (the body looking for a quick energy hit)
- A desire for reward after a hard day
- Environmental cues the TV, a coffee break, 3pm
None of these are signs of weakness. They’re signs that the brain has learned food is a reliable, fast-acting tool for emotional regulation. The problem is that food solves hunger, it doesn’t actually solve stress, boredom, or fatigue.
Willpower Isn’t the Answer
Most of us have tried the willpower approach. We tell ourselves we won’t snack, we set rules, we white-knuckle our way through cravings. And it works, for a while.
Brewer explains why this approach is structurally flawed. The part of the brain responsible for willpower and rational decision-making the prefrontal cortex is the first to go offline when we’re stressed, tired, or overwhelmed. The very moments when we most need control are the moments we have the least of it.
Instead, he argues, the goal isn’t to suppress the behaviour by force. It’s to change what the brain actually values to update the reward.
Awareness Is the Intervention
This is where mindfulness enters not as a spiritual practice, but as a practical tool for interrupting automatic behaviour.
When the urge to eat arises, the practice is simply to pause and notice: What am I actually feeling right now? Am I physically hungry, or is something else going on? What does this urge feel like in my body?
That moment of awareness is not nothing it’s the crack in the automatic loop. It’s the difference between reacting and choosing.
Curiosity Beats Judgment Every Time
One of the more quietly powerful ideas in the book is the shift from self-criticism to curiosity.
When we eat in a way we didn’t intend to, the usual response is shame: “Why did I do that again? What’s wrong with me?” Shame is uncomfortable, and discomfort, as we’ve established, tends to send us straight back to food.
Curiosity asks a different question: “What actually happened there? What was I feeling before I reached for that?” It keeps you engaged with the experience rather than fleeing from it and that engagement is where real change begins.
What This Means for You
If you’ve ever felt frustrated that you “know what to do” around food but can’t seem to do it consistently, Brewer’s framework offers some relief: the problem was never a lack of knowledge. It was a habit loop running on autopilot.
The good news is that habits can be updated. Not through restriction or willpower, but through awareness, curiosity, and a willingness to get genuinely interested in your own experience.
That’s a very different and much more sustainable place to work from.
