Hey!
Simon from Body Development Centre here! Leicester’s premier personal training and weight loss studio.
Today, we’re going to talk about why we keep eating, even when we aren’t hungry anymore. Let’s get into it!
You’ve been there before.
You’ve prepped your meals. You’ve followed your plan. You’ve eaten dinner. You’re no longer hungry.
And then you go back for seconds.
Or grab a biscuit.
Or finish the rest of the ice cream tub.
Or nibble your way through the leftovers until the plate is clean—even if you’re not even enjoying it anymore.
So what gives? Why do we do this—especially when we know we’re not actually hungry?
Enter: The Power of Priming
What’s really going on here is something called priming—an ancient survival mechanism hardwired into your brain.
And believe it or not, it’s not a flaw. It’s actually a feature. One that once helped us stay alive in a world where calorie availability was unpredictable.
A Glimpse Into Our Hunter-Gatherer Past
Imagine yourself not in 2025, but 25,000 years ago. You’re not planning meals with MyFitnessPal or browsing supermarket aisles. You’re wandering forests and plains, hoping to find something edible.
Finding high-calorie food—especially foods rich in fat or sugar—was like striking gold. Your body needed those dense energy sources to fuel your survival.
So when you did find something precious, like honeycomb, your brain would go into overdrive.
It would light up with dopamine (the “do that again” chemical), encouraging you to search for more, eat more, and store more—just in case food became scarce again.
That drive wasn’t greed—it was smart. It helped you survive famines, long winters, and unpredictable food supplies.
Fast Forward to Today
Here’s the problem: Your modern world doesn’t match your ancient brain.
Now, instead of stumbling upon honey once in a blue moon, you’re surrounded by ultra-processed food everywhere you look. Sugary snacks. Fatty takeaways. Salty, sweet, high-calorie foods, 24/7.
And your brain responds the same way it always has:
“This is rare! This is amazing! FIND MORE. EAT MORE. STORE MORE.”
This is priming in action. The initial bite primes the brain to crave more—even when you’re full. Even when you’re not hungry. Even when you know better.
And it’s a completely normal reaction. But it’s also a big part of why long-term weight loss can feel so hard.
So, What Can You Do?
Let’s be clear: this is not about willpower.
You’re not weak. You’re not broken. You’re just working with a brain that evolved in a very different world.
So instead of fighting it with guilt and shame, we work with it—by learning to pause and let the temptation pass.
Here’s the Truth: Temptation Has a Time Limit
Whether your cravings are triggered by priming, emotional eating or are habit-linked, they all have one feature that can be useful to overcome them!
They last no longer than 5 and 15 minutes.
And don’t get me wrong. In that window, they can feel overwhelming. Like the most urgent, irresistible need in the world.
But if you can hold off for that short period, something powerful happens:
The intensity fades. The Emotional Gremlin quiets down and the Logical Human brain comes back online.
Use the “Yes, But…” Strategy
With my personal training clients, I’m not a fan of rigid rules like “You’re not allowed that.” Because what happens when we forbid something? We want it more. We rebel. We feel deprived.
Instead, try this subtle shift:
“Yes, I can eat more… but I’ll wait 15 minutes first.”
You’re not telling yourself no.
You’re creating space.
Space for the Gremlin to settle.
Space for your logical brain—the Human—to regain control.
And more often than not, when the time is up, the urge has passed.
If you do still want it after 15 minutes? That’s okay. You gave yourself a chance to check in—and that alone builds awareness, which leads to long-term change.
Why This Works (Backed by Science)
This isn’t just feel-good advice. Delaying action in moments of temptation is a core strategy in cognitive behavioural therapy (CBT), mindfulness, and even addiction recovery.
Here’s why:
-
Pausing breaks the automatic impulse.
-
Acknowledging the urge without acting on it reduces its power over time.
-
Creating a gap between thought and action builds emotional regulation skills.
-
Noticing what you’re feeling gives you insight into what’s really going on: Am I bored? Tired? Reward-seeking? Emotionally triggered?
The more often you practice the pause, the easier it becomes to step out of the spiral and make conscious choices.
✅ Actionable Steps From Our Journey
If you’re finding yourself stuck in the pattern of eating past fullness, here’s what to try next:
1. Understand What’s Happening
Recognise that the drive to keep eating after you’re full isn’t you being “bad” or “undisciplined.” It’s an ancient survival mechanism called priming—and it’s normal.
2. Notice the Trigger
Is the urge to keep eating linked to:
-
The taste of something delicious?
-
A habit (like always having dessert)?
-
An emotion (like stress or boredom)?
Awareness is the first step to change.
3. Pause With “Yes, But…”
When the urge hits, tell yourself:
“Yes, I can eat more, but I’ll wait 15 minutes first.”
And then, distract yourself. Walk, text a friend, sip water—anything to give your brain space.
4. Check In After the Pause
After 15 minutes, ask:
-
Do I still want this?
-
Am I still physically hungry?
-
What do I really need right now?
You might be surprised by the answer.
5. Celebrate the Win
Even if you do eat more after the pause, celebrate the fact that you paused. That’s progress. You created a gap—and that’s a skill worth building.
Final Thought
You don’t have to be perfect.
You just have to be curious, compassionate, and consistent. As I tell all of my personal training clients, self-knowledge if how you really win this game!
The more you understand how your brain works, the more power you have to make choices that align with your goals—without falling into the all-or-nothing trap.
