Frequently Asked Questions

When your body changes —
but nothing seems to work the way it used to

You might be eating well, exercising regularly, and doing all the things that used to work.
But your energy is lower. Your weight is shifting. Your sleep isn’t as restorative. And something just feels… off.
This is one of the most common patterns I see in women’s health after 40.
Not because you’re doing anything wrong — but because your physiology has changed, and your body now needs a different kind of support.
Below are the questions I’m most often asked in clinic.

Something’s not right…

These are usually the first signs something has shifted — even if everything looks “normal” on paper.

Why do I feel so tired all the time after 40, even when I sleep well?

Feeling tired after 40 despite adequate sleep is often due to changes in sleep quality, hormonal regulation, and blood sugar stability — not just the number of hours slept. Hormonal shifts, stress patterns, and overnight blood sugar dips can all affect how deeply you sleep and how well you recover.

A 2025 review found that repeated glucose fluctuations are linked to fatigue, disrupted sleep, and increased fat storage over time. This reinforces how closely blood sugar regulation is tied to energy and recovery.

“In clinic, I often see women sleeping enough hours but still waking unrefreshed. It’s usually not about sleep quantity — it’s about how well the body is regulating overnight.”
— Tania Lewis, Naturopath (BHSc), Registered Nurse (BSc), Simply Naturopathics Rutherglen

A helpful starting point is supporting stable blood sugar and a consistent wind-down routine before bed.

Could low energy and weight gain be a sign of perimenopause?

Yes. Low energy and weight gain are common early signs of perimenopause, driven by hormonal changes that affect metabolism and energy regulation. Fluctuations in oestrogen and progesterone can influence blood sugar stability, fat storage, and how efficiently your body produces and uses energy.

Most women (around 80%) experience symptoms at menopause (RANZOG, 2023), with common symptoms including sleep disturbance, fatigue, and changes in body composition (Australian Menopause Society).

If this feels familiar, it’s worth stepping back and looking at the broader pattern — not just calories or exercise.

Many women come in thinking they’ve suddenly lost control of their body. In reality, their physiology has shifted — and it needs a different strategy.

Why do I get an afternoon energy crash, even when I eat regularly?

An afternoon energy crash is usually caused by blood sugar fluctuations rather than how often you eat.
Meals that are higher in refined carbohydrates or lower in protein can lead to a spike in energy followed by a noticeable drop a few hours later.
This highlights how blood sugar variability directly affects energy levels and metabolic regulation.

“The 2–4 pm crash is one of the most consistent patterns I see. It’s often linked to how the day starts nutritionally.”
— Tania Lewis, Naturopath (BHSc), Registered Nurse (BSc), Simply Naturopathics Rutherglen

Diabetes Australia (2023) reports that fluctuations in blood glucose levels can significantly impact energy levels, concentration, and fatigue throughout the day. Maintaining stable blood sugar is key to preventing energy dips and supporting consistent energy.

Tip: Starting your day with a protein-rich breakfast can make a noticeable difference.

Why is this happening?

These symptoms are rarely isolated. They tend to reflect how multiple systems are working together — or not.

Why does stress make it harder to lose weight after 40?

Stress increases cortisol, which promotes fat storage, affects insulin sensitivity, and makes weight loss more difficult — especially in midlife.
When stress is ongoing, the body shifts into a more protective, energy-conserving state.

“I often explain this as a safety response. When the body perceives stress, it becomes much less willing to let go of energy stores.”
— Tania Lewis, Naturopath (BHSc), Registered Nurse (BSc), Simply Naturopathics Rutherglen

A 2025 study found that higher daily stress levels were associated with increased blood glucose levels in individuals with insulin resistance.
This highlights how stress can directly disrupt metabolic regulation.
Addressing stress is often a key turning point in weight resistance.

How does blood sugar affect energy, sleep, and weight in midlife women?

Blood sugar stability directly affects energy levels, sleep quality, and weight regulation.
When levels rise and fall quickly, it can lead to fatigue, cravings, disrupted sleep, and increased weight gain over time.

Analysis of metabolic health data by Function Health (2026) found that over 50% of individuals had elevated fasting insulin despite normal glucose and HbA1c levels. This suggests early metabolic dysfunction is common, even when standard tests appear normal.

Tip: Balancing meals with protein, fats, and fibre is one of the most effective starting points.

In midlife, blood sugar becomes less forgiving. Small imbalances that didn’t matter before start showing up as real symptoms.

Can digestive issues cause weight gain or make it harder to lose weight?

Yes — particularly when gut function is affecting inflammation, nutrient absorption, or metabolism.
When digestion isn’t working well, the body’s ability to regulate energy and weight can be impacted.

Research published in Cureus (2023) shows that changes in gut microbiota are associated with altered metabolism and increased risk of weight gain.
The study highlights the role of the gut in regulating energy balance.

Supporting digestion is often a missing piece in weight resistance.

I often see weight resistance where gut function is still under strain, even when diet and exercise are consistent.

What does it mean if my blood tests are ‘normal’ but I still feel off?

Normal blood tests do not always mean optimal health — they reflect population averages, not individual function.
Early imbalances can exist within “normal” ranges and still produce symptoms.

“In clinic, I often see results that are technically ‘normal’ but don’t match how the person feels. That’s where pattern-based interpretation matters.”
— Tania Lewis, Naturopath (BHSc), Registered Nurse (BSc), Simply Naturopathics Rutherglen

The Royal Australian College of General Practitioners (RACGP, 2023) notes that reference ranges are based on population averages and must be interpreted alongside symptoms. This reinforces the importance of clinical context.

If you still feel off, it’s worth looking beyond individual markers to the broader pattern.

Can this actually be helped?

Once the pattern is clearer, the next question is whether it can be shifted.

Can a naturopath help with fatigue, weight gain, and gut issues?

Yes — particularly when these symptoms are connected. Rather than treating each issue separately, naturopathic care looks at how your systems are interacting and what’s driving the pattern.

“Symptoms rarely exist in isolation. When we support the underlying drivers, we often see improvements across multiple areas at once.”
— Tania Lewis, Naturopath (BHSc), Registered Nurse (BSc), Simply Naturopathics Rutherglen

The National Institute of Complementary Medicine (NICM, 2023) emphasises that naturopathic care uses a whole-person, systems-based approach. This supports more personalised and targeted treatment.
The key is understanding the pattern before applying solutions.

How is a naturopathic approach different from what my GP has already checked?

Your GP plays an essential role in ruling out and managing disease.
A naturopathic approach looks at how your body systems are functioning together — especially when symptoms persist without a clear diagnosis.
Both roles are complementary.

“Most clients I see have already had tests. My role is to connect those results with symptoms to understand the underlying pattern.”
— Tania Lewis, Naturopath (BHSc), Registered Nurse (BSc), Simply Naturopathics Rutherglen

The World Health Organization (2023) supports integrative approaches that consider whole-person health and system interactions. This type of care complements, rather than replaces, conventional medicine.
I add depth to understanding ongoing symptoms.

What would this look like for me?

If you’re considering support, it helps to know what the process actually involves.

What happens in an initial naturopathic consultation at Simply Naturopathics?

Your initial consultation is a structured, in-depth assessment of your symptoms, history, and underlying patterns.
I look at your energy, sleep, digestion, weight changes, and lifestyle, alongside any available blood tests, to build a clear picture of what’s driving your symptoms.

My goal in that first session is to help you feel understood and to start mapping out why things have changed — not just what to do next.

An article in the Global Journal on Quality and Safety in Healthcare (2024) highlights that person‑centred care — care that is tailored to the individual — is strongly linked to higher patient satisfaction and is widely recognised as contributing to better overall wellbeing.
You’ll leave with clarity and a clear next step.

Do I need functional testing, or can you work with my existing blood tests?

In many cases, we can start with your existing blood tests.
Functional testing is used when we need deeper insight, but often your current results already contain valuable information when interpreted in context.

I regularly work with existing results. It’s often about how we interpret them, not how many tests we run.

The RACGP (2023) notes that pathology results should be interpreted within the context of the individual, not in isolation. This aligns with a functional approach, where patterns and trends are prioritised over single markers.
If further testing is needed, it’s recommended thoughtfully and with a clear purpose.

Is this worth it?

This is usually where the final hesitation sits.

How long does it take to see results with a structured naturopathic plan?

Most people notice early shifts within the first few weeks, but meaningful, lasting change builds gradually over time — and depends on how long the underlying pattern has been present.
Early improvements often include changes in energy, digestion, or sleep. These are signs the body is starting to respond.

I describe the first phase as recalibration. The deeper, more sustainable changes build from there — especially if symptoms have been building for years.
— Tania Lewis, Naturopath (BHSc), Registered Nurse (BSc), Simply Naturopathics Rutherglen

Research shows that structured lifestyle interventions can produce measurable improvements in metabolic markers within 6–8 weeks, including changes in body composition and insulin sensitivity (Cooper et al., 2022). However, longer-standing concerns — particularly those involving metabolism, hormones, or chronic stress — often take longer to stabilise and require ongoing support.

Tip: Focus on consistency rather than perfection or quick fixes — that’s what drives lasting change.

Still not sure where to start?

If you’re recognising yourself in these patterns, the next step isn’t doing more of the same.

It’s understanding what’s actually driving the change in your body — and having a clear plan for how to support it.
