I Thought I Was Eating Healthy… Until I Learned This

If you’ve ever felt like you’re doing everything “right” but still don’t feel good in your body… you’re certainly not alone.
There was a time I switched to using agave syrup instead of sugar.
I thought I was making a much better choice:
Less calories. More natural. “Healthier.”
I thought I was doing something good for my body.
Until I started nutrition classes and learned it was actually really bad for the liver!
That moment stayed with me.
I thought I was doing everything right.
But I wasn’t.

When I look back, it wasn’t just one thing.
It was a whole collection of beliefs I had picked up over the years:
Choosing low-fat or “no fat” products because I thought fat made you gain weight and was bad for your health
Eating cereal or oatmeal every morning because that’s what a “healthy breakfast” looked like
Thinking honey didn’t count as sugar
Eating a lot of fruit because I believed I needed it for vitamins (and more was better)
And I’m sure some of this will sound familiar.
Because this isn’t just my story.
It’s exactly what I still see today with so many women I work with.
Women who are trying so hard to do the right thing…
And yet feel bloated, tired, gaining weight, constipated or completely out of sync with their bodies.
The Part We Don't Talk About Enough
Here’s the part we don’t talk about enough:
We’re not just guessing wrong… we’re being guided in a certain direction.
By marketing.
By the food industry.
By headlines that simplify complex science into something sellable.
We’re taught to trust labels like:
“low fat”
“no added sugar”
“natural”
“plant-based”
… because they sound safe.
But those labels are often designed to sell - not to give you the full picture.
And then there’s something else most people don’t realise:
What we believe to be “healthy” is constantly changing.
One day we learn something is harmful - so companies adapt, rebrand, and promote a “better” alternative.
Think BPA-free.
Think PFAS-free.
It creates a sense of safety.
But it doesn’t necessarily mean the product is truly harmless - just that it’s different from what we were told to fear before.
The same happens in nutrition.
For years, we were told to avoid butter.
To fear eggs.
To choose low-fat everything.
Now we know the story is far more nuanced.
And it will keep evolving.
Because most of the time, we’re looking at small pieces of a much bigger puzzle - while the body doesn’t work in isolated parts.
What Actually Changed
And yet - this is important…
This isn’t about becoming perfect.
I didn’t swing from agave to never touching anything sweet again.
I didn’t suddenly eliminate everything I once believed in.
Because that’s not realistic… and it’s not sustainable.
What changed was something much more powerful:
👉 Awareness
👉 Understanding
👉 And learning how to read between the lines
This journey of unlearning and relearning…
Of going from “I thought this was healthy” to “Now I understand what my body actually needs”…
Is exactly what I’m currently writing about in my book.
Some of you might remember I mentioned it before.
Over time, the direction has changed and become clearer:
It’s not just about giving information.
It’s about helping you make sense of the confusion.
To connect the dots between what you’ve been told… and how you actually feel.
To stop feeling like a stranger in your own body.
I’m aiming for a launch next year, and I’ll be sharing more behind-the-scenes moments along the way - including little glimpses like this.
For now, I’ll leave you with this:
What’s something you used to believe was healthy… that you see differently now?
I’d genuinely love to hear.
Because often, that’s where everything begins.
If this resonated, my cookbook is a great place to start.... and stop guessing about which fats to use for cooking, how much protein to eat, which sweeteners to use...?
