Tania Lewis, Naturopath, Rutherglen VIC
Tania Lewis is a naturopath based in Rutherglen, Victoria, working with women in perimenopause and post-menopause experiencing persistent fatigue, weight changes, and low energy that haven’t responded to standard care. She sees clients in person and via telehealth across Australia. As an ANTA member with a clinical background in acute nursing, she brings systems-based clinical thinking to fatigue, weight, and energy, looking across metabolism, thyroid, cortisol, and gut rather than at symptoms in isolation.
When your energy and weight no longer respond the way they used to
You’re eating carefully. You’re moving when you can. You’re going to bed at a reasonable hour. And yet the fatigue is constant, the weight isn’t shifting, and you feel like your body is working against you.
This is one of the most common presentations I see in post-menopausal women, and one of the most under-investigated. The standard advice to eat less and move more doesn’t account for what’s actually happening across your metabolism, thyroid function, cortisol rhythm, and hormonal baseline after menopause. When those systems shift, the body responds differently. Understanding how is where the work begins.
This page is for you if
What’s actually happening in your body
During perimenopause and after menopause, three interconnected feedback loops shift at once. The hypothalamic-pituitary-ovarian axis, which regulates oestrogen and progesterone, changes fundamentally. That directly affects the hypothalamic-pituitary-adrenal axis, which governs your cortisol and stress response, and the hypothalamic-pituitary-thyroid axis, which controls your metabolic rate and energy production.
When all three are under load at once, the effects compound. That’s why fatigue, weight resistance, and disrupted sleep so often arrive together, and why addressing one in isolation rarely produces lasting results.
Why “normal” results don’t always mean normal
Standard pathology reference ranges are designed to identify disease, not the point at which your body is functioning below its best. A result that sits within the reference range isn’t necessarily a result that indicates you’re well.
In practice, this means thyroid markers, iron studies, blood glucose, and cortisol patterns can all sit at the lower end of normal, technically unremarkable, yet clinically relevant.
The gap between ‘not diseased’ and ‘functioning well’ is where many women in perimenopause and beyond find themselves.
This is one reason I use functional blood chemistry interpretation to analyse standard pathology. It assesses where your markers sit within evidence-informed optimal ranges, which are narrower and more clinically meaningful than standard reference ranges for presentations like yours.
From there, I build a written treatment plan personalised to your clinical picture, not a protocol designed for most people that fits you adequately.
From there, I build a written treatment plan personalised to your clinical picture, not a protocol designed for most people that fits you adequately. Where clinically indicated, I can arrange or interpret specialist testing, including Continuous Glucose Monitoring for blood sugar and insulin patterns, Microba Microbiome Analysis, and Hair Tissue Mineral Analysis.
I work alongside your GP and other treating practitioners, not in opposition to them. My clinical background in acute nursing means I understand the medical model and can communicate clearly with your treating team. If something in your assessment warrants referral or further investigation, I’ll say so.
What clients commonly notice
Midlife women who present with fatigue, weight resistance, and low energy often share a similar pattern: a period of managing reasonably well, followed by a gradual shift that didn’t respond to what had worked before.
In my clinical experience, the most consistent finding is that the contributing factors are rarely isolated. Thyroid function, blood sugar regulation, sleep architecture, gut health, and cortisol patterns are almost always interconnected in this presentation. Addressing one without the others produces limited and short-lived results.
What clients typically notice over structured care is a gradual return of energy, not a dramatic reversal, but a meaningful shift in how they feel by mid-morning, how they sleep, and how their body responds to food and movement. The 3am waking often improves before the fatigue does. Weight changes tend to follow once the underlying drivers are addressed, rather than leading the process. I don’t promise specific outcomes. What I offer is a clear picture of what’s driving your symptoms and a structured plan to address it.
Frequently asked questions
Can a naturopath help with fatigue and weight gain after menopause?
In my clinical experience working with menopausal women, fatigue and weight resistance are rarely caused by a single factor. They’re almost always the result of several interconnected systems: thyroid function, blood sugar regulation, sleep quality, cortisol patterns, and hormonal shifts, operating under increased load at once. Naturopathic care assesses and addresses these as a whole rather than in isolation.
The research supports an individualised approach. A randomised controlled trial in perimenopausal women found that personalised dietary guidance produced the broadest improvement in menopausal symptoms, including fatigue, compared with general health education alone (Hao et al., 2022). A separate systematic review and meta-analysis found that whey protein improved muscle strength and lean mass in post-menopausal women, but only when combined with resistance training; protein alone, without the training, made no significant difference (Kuo et al., 2022). The clinical principle is consistent: what you eat and how you move work together, and the right plan depends on your individual picture rather than a generic protocol.

My blood tests came back normal but I still feel exhausted. What does that mean?
Standard pathology reference ranges are designed to identify disease, not the point at which your body is functioning below its best. A result that sits within the reference range isn’t necessarily a result that indicates you’re well. In my practice, I use functional blood chemistry interpretation to assess where your markers sit within evidence-informed optimal ranges, which are narrower than standard reference ranges and more clinically meaningful for presentations like yours. If your thyroid, iron, fasting glucose, or cortisol patterns are sitting at the lower end of normal, that’s worth examining properly.
How long before I see results?
This depends on how long the pattern has been present, how many systems are involved, and how consistently the plan is followed. In my clinical experience, most post-menopausal women with fatigue and weight resistance begin to notice meaningful shifts in energy within 4 to 12 weeks of structured care, particularly in how they feel in the morning and mid-afternoon, and in overnight sleep quality. Weight changes tend to follow rather than lead. There are no shortcuts here, and I won’t suggest there are. What I offer is a clear plan, a clinical rationale for each step, and structured follow-up to assess progress.
Do I need to stop my current medications or HRT to work with you?
No. I work alongside your existing medical care, including hormone replacement therapy, thyroid medication, and any other prescribed treatments. I’ll take a full medication and supplement history at your initial consultation and flag any interactions clearly. If anything in your assessment suggests your current medical management needs review, I’ll recommend you discuss that with your GP, and I won’t make changes unilaterally.
What’s the difference between seeing a naturopath and seeing my GP for this?
A GP consultation is typically 12 to 15 minutes and is appropriately focused on diagnosis, prescribing, and referral. A naturopathic initial consultation at Simply Naturopathics runs 60 to 75 minutes and covers your full history, lifestyle, diet, sleep, stress patterns, existing pathology, and gut health in detail. The two approaches serve different purposes and work best together. My clinical background in acute nursing means I understand the medical model and can communicate clearly with your treating practitioners. I don’t work in opposition to your GP; I work alongside them.

Ready to take a proper look?
If your energy, weight, and fatigue haven’t responded to what you’ve already tried, a thorough clinical assessment is a reasonable next step. You’ll leave your initial consultation with a written plan built around your actual presentation, not a protocol designed for someone else.
If you’re not sure whether this is the right fit, the Clarity Call is a good place to start. It’s ten minutes by phone, no obligation.
