50 years young.

Still training.
Still learning.
Still getting stronger.

💚 Nourishing my body
💚 Moving most days
💚 Sleeping deeply
💚 Challenging myself physically

Longevity isn’t luck.
It’s built through the choices we make every day.

It’s never too late to start.

As a clinical nutritionist, I work with women navigating:
• Perimenopause
• Low energy and hormonal shifts
• Gut health challenges
• Metabolic changes

Because feeling strong at this stage of life should be the norm — not the exception.

Collagen vs Protein Powder – are they the same? 🤔

Both are popular supplements… but they serve very different purposes in the body.

✨ Protein powders (like whey or plant proteins) are considered complete proteins, meaning they contain all essential amino acids needed to support muscle repair, metabolism and satiety.

✨ Collagen peptides are rich in specific amino acids such as glycine, proline and hydroxyproline which help support skin, joints, connective tissue and gut lining.

However, collagen is not a complete protein, so it shouldn’t replace your primary protein source if your goal is muscle recovery, strength or meeting daily protein requirements.

✔️ Protein powder → best for meeting protein needs and supporting muscle
✔️ Collagen peptides → targeted support for skin, joints and connective tissue

Think of collagen as a functional add-on, not a full protein replacement.

Food first always wins – but supplements can help fill specific gaps when used intentionally. 🌿

Hey, I’m Tracy 👋
Just a heads up on a Clinical Nutritionist’s qualifications and holistic practice methods (in case you wondered what I do vs Dieticians vs general nutrition consulting) 💚

🌈 Eat the Rainbow – Especially in Perimenopause

This isn’t just a pretty salad… it’s hormone and gut support on a plate.

During perimenopause, fluctuating oestrogen impacts:
• Blood sugar stability
• Gut motility
• Histamine response
• Mood + energy
• Inflammation levels

And one of the most powerful (and underrated) tools?
Colourful plant diversity.

Each colour represents different polyphenols and phytonutrients that:

✨ Support the estrobolome (your gut bacteria that metabolise oestrogen)
✨ Feed beneficial microbes with diverse fibres
✨ Reduce oxidative stress
✨ Support liver detoxification pathways
✨ Calm inflammation

Think:
🔴 Lycopene (tomatoes, capsicum)
🟠 Beta-carotene (carrots, pumpkin)
🟢 Sulforaphane (cruciferous veg)
🟣 Anthocyanins (red cabbage, berries)
⚪ Prebiotic fibres (onion, garlic, leeks)

Perimenopause isn’t a time to eat less.
It’s a time to nourish smarter.

More colour = more diversity = more resilience.

Your hormones love a rainbow. 🌈

I’ve recently introduced a Longevity Nutrition Program designed for individuals wanting to support healthy ageing using personalised data.

What makes this different is that I combine:

✔ Functional blood testing (to assess current metabolic, inflammatory and hormonal markers)
✔ Targeted DNA insights (to understand nutrient processing, detoxification and metabolic tendencies)

Blood tests show us what is happening now.
DNA shows us how your body is wired to respond.

When interpreted together, this allows for a highly individualised nutrition strategy - rather than generic meal plans or supplement lists.

This program is particularly helpful for:
• People with a family history of certain health conditions
• Those experiencing fatigue or stubborn weight changes
• Individuals wanting proactive, data-driven health support

Perimenopause supportive food doesn’t have to be complicated… or boring. 💚

This green curry is one of my favourite ways to make tofu genuinely delicious, while loading up on cruciferous vegetables that support hormone metabolism and liver pathways.

Think:
✨ Broccoli or broccolini (hello sulforaphane)
✨ Cauliflower for gentle detox support
✨ Bok choy for fibre + calcium
✨ Tofu for plant protein + phytoestrogen support.

A meal like this delivers:

✔️ Protein to stabilise blood sugar
✔️ Fibre to support oestrogen clearance
✔️ Phytonutrients to reduce oxidative stress
✔️ Healthy fats to keep you satisfied

Functional food. Hormone supportive. Simple enough for a weeknight.

Tofu can be incredible when you cook it well — and your hormones will thank you 💚

If you’re exhausted but still functioning…
this is for you.

Most of the women I work with are not lacking discipline.

They are holding careers, families, relationships, expectations (and themselves) - to very high standards.

The pressure isn’t usually coming from the outside.

It’s internal.

“I should be managing this better.”
“I just need to be more consistent.”
“Why can’t I get on top of my health?”

But when nervous system load is high and blood sugar is unstable, the body shifts into conservation mode.

Cravings increase.
Sleep fragments.
Energy dips.
Hormones downshift.

That isn’t a mindset failure.
It’s physiology protecting you.

The goal isn’t to become more disciplined.

The goal is to increase your capacity.

When we stabilise blood sugar, improve protein intake, restore micronutrient sufficiency, support recovery, and regulate stress signalling —> consistency becomes easier.

Not because you’re trying harder.

Because your body can finally cooperate.

And that changes everything.

During perimenopause, women become less insulin-sensitive.
👉 Oestrogen fluctuations reduce how efficiently insulin moves glucose out of the bloodstream and into cells.
👉 Result: higher post-meal blood sugar, more fat storage, more inflammation, and those energy crashes.

Here’s the powerful workaround: move your body after meals.

When muscles contract, they absorb glucose without needing insulin.
✔ Muscle contractions activate GLUT-4 transporters
✔ Glucose is pulled straight into muscle cells
✔ Blood sugar levels drop more efficiently
✔ Less demand on insulin = better metabolic health 💚

You don’t need a workout.
🚶‍♀️ 10–20 minutes of walking
🏠 Light housework
🧘‍♀️ Gentle mobility or stretching

Consistency beats intensity.

In perimenopause, movement isn’t necessarily about burning calories- consider blood sugar control too 🔥

Weekends look different, and that’s intentional. Sprint training is not part of my usual routine- it felt uncomfortable in the moment but that’s part of dopamine reward 😁
✔️ Training is still a priority, but intensity is flexible
✔️ Meals are nutrient-dense, not perfect
✔️ Protein is non-negotiable
✔️ Fibre, colour & gut support still matter
✔️ Enjoyment and recovery are part of the plan

Nutrition isn’t about rigid rules - it’s about supporting energy, hormones, gut health and recovery in real life.
This is what sustainability actually looks like.

Your thyroid helps regulate:
• Metabolism
• Body temperature
• Energy production
• Fat and carbohydrate use

It’s highly sensitive to energy availability, hormones and stress.

During Peri & Post Menopause:
• Oestrogen and progesterone fluctuate or decline
• Insulin sensitivity may reduce
• Muscle mass naturally decreases without adequate protein & resistance training

➡️ The thyroid becomes more sensitive to stressors, including low calories and excessive cardio.

As a Clinical Nutritionist, I can:
✅ Order comprehensive thyroid panels
✅ Interpret patterns alongside symptoms
✅ Address nutrition, stress and metabolic drivers
✅ Support thyroid function without defaulting to restriction

If your labs are “normal” but your body doesn’t feel it, your thyroid may be responding to long-term stress.
Book a consultation to explore appropriate testing and personalised support.
