The 5 Childhood Eating Habits That Might Still Be Controlling Your Diet

I had one of my big diet realisations last year when I was stuffing my face with chips after I put the kids to bed. Anybody who knows me knows that my biggest vice is chips (packet crisps, not the hot chips variety). Most nights, after a long day, and after putting the kids to bed, I’d plonk myself on the couch and as soon as I started watching TV, I craved a salty snack. 3 packets of chips later I go to bed, hating myself and promised myself I’d start fresh tomorrow.

My realisation came when I asked myself “Why do I always feel like a salty snack when I sit down to watch TV at night?” After a few minutes of thinking, I realised it was a habit that was drilled into me as a kid. The habit formed when I went to the movies and ate popcorn each time! Every time I went to the movies I ate popcorn. Habit formed.

Then I thought, what other habits that I formed as a kid still affect me subconscously to this day? With some more reflection, the answer shocked me.

Think back to when you were a kid.

You probably didn't think much about calories, protein, portion sizes or “healthy eating”. You simply ate what was put in front of you.

But somewhere along the way, we all picked up rules about food.

“Finish everything on your plate.”
“You need to eat your vegetables before you get dessert.”
“It’s Friday night, so we're having takeaway.”
“We're going to the movies, so let's get popcorn and lollies.”

At the time, these seemed completely normal.

And that's the point.

Many of the eating habits we have as adults aren't conscious decisions. They're patterns we learned as children and have been repeating for decades.

Once you recognise them, you can change them.

Here are five of the most common childhood eating habits that may still be influencing the way you eat today.

1. “Finish everything on your plate.”

This is one many of us will remember.

“There are starving children in Africa. Don't waste your food.”

The intention was good. Our parents wanted us to appreciate food and not waste it.

But there's a problem with the lesson we learned.

We were taught to ignore our body's signals of fullness and instead listen to an external rule: The food on the plate must be finished.

Fast forward 30 or 40 years and that habit can look like:

• “I know I'm full, but I'll finish it anyway.”

• “I shouldn't leave food on my plate.”

• “There's only a little bit left.”

• “I paid for it, so I might as well eat it.”

The problem isn't the food.

It's that we've learned to stop eating based on what's left, rather than how hungry we are.

2. “You have to earn dessert.”

For many of us, food came with a reward system.

Eat your vegetables → get dessert.

Finish your dinner → you can have ice cream.

Be good → we'll get you a treat.

Again, there was nothing particularly sinister about it. Parents were simply trying to get their kids to eat their vegetables!

But over time, we can start associating certain foods with reward, comfort and celebration.

That's why as adults, we might automatically reach for something sweet after a difficult day.

“I've had a stressful day. I deserve a chocolate.”

Or:

“I've been good all week. I deserve a takeaway.”

Food has become a reward.

3. “Certain foods belong to certain occasions.”

Think about the foods you associate with particular activities.

Movies = popcorn and lollies.

Friday night = takeaway.

Birthday = cake.

Sunday = big family lunch.

Watching sport = chips and beer.

These associations can become incredibly powerful.

You don't necessarily walk into the cinema thinking, “I'm hungry and I need 600 calories of popcorn.”

You see the cinema...

…and your brain says:

“Popcorn!”

That's because eating isn't always driven by hunger. Sometimes it's driven by environment and routine.

And after doing something hundreds of times, the behaviour becomes almost automatic.

4. “Clean your plate before you leave the table.”

This is slightly different from simply being told not to waste food.

Many of us were taught that leaving food behind was bad manners.

You didn't leave the table until everything was gone.

Over time, this can create another problem: portion sizes become something we're given rather than something we control.

And as adults, we often continue the pattern.

Restaurant gives us a huge serving?

We eat it.

Someone offers us seconds?

We accept.

There's food left over?

We finish it.

The portion becomes the instruction.

5. “Treats are for special occasions.”

This one sounds like it should be a good thing.

But sometimes, making certain foods too special can have the opposite effect.

If you grew up hearing:

“You only get chocolate on Saturday.”

“Lollies are a special treat.”

“Ice cream is only for birthdays.”

those foods can become incredibly desirable.

And when you finally get access to them?

You might feel like you need to make the most of the opportunity.

That can lead to overeating because somewhere in the back of your mind is the thought:

“I better eat it now because I don't know when I'll get it again.”

The biggest lesson?

Your eating habits didn't appear out of nowhere.

They were built over years and years of repetition.

Some came from your parents. Some came from school. Some came from family traditions.

And some came from experiences like birthdays, holidays, movies and weekends.

And because you've repeated these behaviours for decades, they can feel like “just the way I am.”

But they're not.

They're habits.

And habits can be changed.

The goal isn't to suddenly become the person who weighs every gram of food, counts every calorie and never eats dessert.

That's not sustainable — and it's certainly not much fun.

Instead, start by becoming more aware.

Next time you find yourself eating something automatically, pause for a moment and ask:

“Am I actually hungry, or am I simply following an old habit?”

Sometimes you'll still choose to eat it.

And that's perfectly okay.

The difference is that you made the choice.

What are some habits you’ve formed as a kid that still creep into your food and diet today? I’d love to hear from you.

And as always, because you’ve made it to the end of this blog, here’s a really funny dad joke:

My teacher asked me if I knew a country without the letter “r” in it. I said “No way!”
