What Is Food Noise? (And Why It’s Not Just in Your Head)

If you’ve ever felt like you’re thinking about food all the time…

What to eat.
What not to eat.
Why you’re hungry again.
Why the cravings keep coming back.

You’re not alone.

And if you’ve read my previous blog on "Turning Down the Volume on Food Noise", you’ll know this is something many people experience, especially in today’s fast-paced, information-overloaded world.

But here’s where I want to take the conversation a little deeper.

Because while mindset, habits and environment absolutely play a role, there’s also a biological side to food noise that often gets overlooked.

When It’s Not Just About Discipline

Many of the women I work with are doing a lot of things right.

They’re:

• eating relatively well
• trying to move their bodies
• making an effort to prioritise their health

And yet they still say things like:

• “I feel hungry all the time.”
• “I can’t stop thinking about food.”
• “It feels harder than it used to."
• "I struggle with cravings."

This is often the point where people start to question their discipline.

But in many cases, it’s not a lack of discipline. It’s a shift in how the body is regulating hunger and fullness.

The Missing Piece: Your Hunger Hormones

Your appetite isn’t controlled by willpower.

It’s regulated by a complex system of hormones that communicate between your gut, brain and metabolism.

One of the key players in this system is a hormone called GLP-1.

GLP-1 is released after you eat and helps your body:

• recognise when you’re full
• regulate blood sugar
• slow digestion so you stay satisfied longer
• maintain steady energy levels

When this system is working well, eating feels relatively straightforward.

You feel hungry…
You eat…
You feel satisfied…
You move on.

But when that signalling becomes less effective, that’s when things can start to feel different.

Why Food Noise Can Get Louder Over Time

One of the most common things I hear is:

“I feel like my body has changed.”

And for many people, particularly in their 40s and beyond, that’s actually true.

It’s not that your body has stopped working. But the efficiency of your appetite signalling can shift.

Things like:

• poor sleep
• chronic stress
• busy, inconsistent eating patterns
• highly processed foods
• high carb diets
• gut health imbalances
• hormonal changes

can all impact how clearly your body sends and receives hunger signals.

Which can lead to:

• feeling hungry sooner after eating
• reduced satisfaction from meals
• stronger or more frequent cravings
• more mental energy spent thinking about food

In other words, more noise.

Why GLP-1 Is Suddenly Everywhere

If you’ve been hearing more about GLP-1 lately, you’re not imagining it.

Medications that target this hormone have brought a huge amount of attention to how appetite is regulated in the body.

For many people, this has been a bit of a lightbulb moment.

Because it shifts the conversation from:

“Why can’t I just eat less?”, to “What’s happening in my body that’s making this harder?”

And that’s an important shift, because it opens the door to a more supportive, less judgmental approach to health.

The Balance: Biology and Behaviour

Now, this doesn’t mean that habits don’t matter.

They absolutely do.

What we eat, how we eat, how we sleep, how we manage stress, all of these influence how our body regulates hunger and energy.

But it also means we need to consider both sides:

• the behavioural patterns (which we explored in the previous blog)
• the biological signals driving those patterns

Because when your biology is supported, healthy choices tend to feel easier, more natural and less like a constant mental battle.

A Different Way to Think About Food Noise

Instead of asking, “Why can’t I be more disciplined?” 

A more helpful question might be, “What might my body be trying to tell me?”

Am I under-fuelling?
Am I stressed or overtired?
Is my blood sugar unstable?
Have my hunger signals become a bit out of sync?

This shift from judgement to curiosity is often where things begin to change.

Where to From Here?

Food noise isn’t something you need to “fight” or suppress. It’s something to understand.

And when you understand it, both from a behavioural and biological perspective, you can start to respond in a way that actually supports your body.

In the next blog, we’ll take a closer look at GLP-1: What it is, how it works, and why it’s become such a big conversation in the world of weight loss and metabolism.

Final Thought

If you’ve been feeling like food has taken up more space in your mind than you’d like, it’s not a personal failure.

It may simply be a sign that your body needs a different kind of support.

If this resonates, take a moment to notice what your own patterns look like right now.

Awareness is always the first step.
