What Is Healthy Hormones About?
You’ve probably been told your painful periods are just part of being a woman. Maybe a doctor ran basic bloodwork, told you everything looked normal, and sent you home with an NSAID prescription. Belinda Kirkpatrick’s opening argument is worth hearing out: period pain is common, but common is not the same as normal. “A menstrual cycle should ideally be free of negative symptoms,” she writes, and the rest of the book is built around proving that’s achievable.
Kirkpatrick is an Australian naturopath and nutritionist with a Bachelor of Health Science and a Master of Reproductive Health, and she’s been in clinical practice specializing in women’s health for over a decade. She’s not writing theory here. The book reads like a detailed intake session with someone who has heard these questions a thousand times and knows exactly which levers to pull. She covers PCOS, endometriosis, PMS, thyroid health, and fertility, using the same organizing principle throughout: symptoms are downstream of mechanisms, and mechanisms respond to targeted interventions.
Where this book fits in the crowded hormone-health shelf: less clinically dense than Aviva Romm’s Hormone Intelligence, more mechanistically grounded than Angelique Vermeulen’s Happy Hormones. It lands in a genuinely useful middle range for women who want to understand what’s happening in their bodies without needing a medical degree to follow along.
Why Your Hormones Are Driving Your Weight
Here’s something that almost never comes up in weight loss conversations: hormones are not a separate problem from weight. They’re woven into the same system.
Kirkpatrick maps out three specific connections worth understanding. First, oestrogen excess changes how the body distributes fat (hips, thighs), drives water retention, and creates the kind of persistent bloat that looks like weight gain on the scale. Second, insulin resistance (the most common root cause of PCOS, in her framework) works both directions: excess body fat raises androgen production and worsens insulin sensitivity, while insulin resistance makes fat loss measurably harder. The cycle reinforces itself. Third, cortisol drives visceral fat accumulation and carbohydrate cravings directly, not as a side effect of stress but as a core metabolic function.
The practical implication isn’t “fix your hormones to lose weight” as some kind of magic shortcut. It’s that if your appetite and weight feel disconnected from your actual effort, the hormonal picture is worth examining. Systems respond better to targeted interventions than to willpower applied to one variable in isolation.
For women with PCOS especially, this reframe matters. Kirkpatrick’s position (consistent with current endocrinology) is that PCOS is primarily a metabolic condition driven by insulin resistance that happens to express itself through hormonal symptoms. The ovaries, under the influence of excess insulin, produce more testosterone. That disrupts ovulation. Addressing the blood sugar upstream often does more than any hormonal treatment downstream.
How Does Kirkpatrick Explain the Main Hormonal Conditions?
Oestrogen Dominance
The liver clears oestrogen by converting it into excretable forms. The gut then binds those forms to fibre and eliminates them. When either pathway fails (overburdened liver, low-fibre diet, disrupted gut microbiome), oestrogen gets reabsorbed rather than excreted, creating relative oestrogen excess even when the ovaries are producing normal amounts.
The downstream symptoms of this are recognizable: heavy or painful periods, breast tenderness before the period, fluid retention, mood shifts around ovulation, and difficulty losing weight around the hips. These are not random or mysterious. They’re the predictable output of a specific physiological process.
What supports oestrogen clearance, according to Kirkpatrick:
- Cruciferous vegetables daily (broccoli, cauliflower, kale, brussels sprouts) provide compounds (I3C and DIM) that drive the liver’s oestrogen metabolism pathways
- 2 tablespoons of ground flaxseeds daily for gut fibre and mild anti-oestrogenic lignans
- Probiotic foods or supplements to maintain the gut bacteria that prevent oestrogen reactivation in the bowel
- Reducing alcohol, since the liver prioritizes alcohol metabolism and deprioritizes oestrogen clearance
PCOS
Kirkpatrick draws a distinction that a lot of women have never heard: a polycystic ovary on ultrasound is not the same as a PCOS diagnosis. The syndrome requires a combination of clinical, hormonal, and imaging criteria. Many women are told they have PCOS based on imaging alone, which is both inaccurate and unnecessary.
For women who do have PCOS (the syndrome), her framework is direct:
“The fastest way to regulate your cycle and promote ovulation is by addressing insulin resistance in the ovaries. A low-sugar and low-carbohydrate diet is recommended for women with PCOS.”
The supporting protocol includes spearmint tea (2-3 cups daily, supported by clinical trials for reducing free testosterone), cinnamon tea (2-3 cups daily for insulin sensitization), strength training as the exercise priority, and practitioner-supervised supplementation with inositol, zinc, magnesium, and chromium.
Endometriosis
Endometriosis is oestrogen-dependent: the tissue that grows outside the uterus responds to oestrogen the same way the uterine lining does. Reducing oestrogen load is structural management of the condition, not a lifestyle preference. Kirkpatrick stacks the oestrogen-clearance protocol above with anti-inflammatory nutrition: eliminating dairy, gluten, corn, soy, and sugar; limiting red meat to roughly one serving per week (arachidonic acid feeds inflammatory prostaglandins); and replacing coffee with green tea.
She’s explicit that this works alongside medical management, not instead of it. Surgery, when indicated, should happen. The dietary approach shapes the hormonal environment that surgery is operating in.
Stress and the Cortisol-Progesterone Relationship
Both cortisol and progesterone are synthesized from the same precursor molecule. Under chronic stress, the body preferentially makes cortisol, leaving less substrate available for progesterone. The result: short luteal phases, premenstrual spotting, heightened PMS, suppressed ovulation. This explains why cycles get worse during high-stress periods. Most women have noticed the pattern without ever having a name for the mechanism.
“High cortisol levels can decrease the production of progesterone and result in a relative progesterone deficiency or relative oestrogen excess. This may exacerbate negative menstrual symptoms and, in cases of severe or chronic stress, even delay ovulation.”
Kirkpatrick’s response is specific rather than vague. For heavy exercisers especially: reducing high-intensity exercise frequency (bootcamp, running) to no more than 2-3 times per week, because intense exercise raises cortisol acutely and can suppress ovulation. This is counterintuitive and often resisted. She states it directly and explains why.
What Does the Naturopathic Toolkit Actually Look Like?
Kirkpatrick’s core nutrition framework is almost aggressively simple: every meal should contain protein, good fats, and something fresh. That’s it. No calorie counting, no macronutrient math. The formula ensures blood sugar stays stable (protein and fat slow glucose absorption), inflammation is managed, and micronutrient needs are met through fresh produce. Carbohydrates exist but they’re accompaniments, not foundations.
Beyond food, the toolkit has three practical layers:
Herbal teas as daily protocol. Kirkpatrick organizes teas by mechanism rather than vague “wellness” claims. Spearmint for androgen reduction. Cinnamon for insulin sensitization. Dandelion root and St Mary’s Thistle for liver support. Licorice root for adrenal recovery (contraindicated with high blood pressure). These are low-risk, self-prescribable, and supported by at least some clinical evidence for each use.
Pathology testing literacy. Most women who go to a GP with cycle symptoms receive a single blood draw without context. Kirkpatrick explains what a useful baseline looks like: Day 3 hormonal panel (FSH, LH, oestrogen, progesterone, androgens), mid-luteal progesterone timed to 7 days before the period (not necessarily day 21), and a full thyroid panel including antibodies. Her key point:
“Optimal health is what we are aiming for, not just absence of ill health.”
Falling within standard reference ranges is not the same as functioning at an optimal level. A mid-luteal progesterone of 6 nmol/L confirms ovulation happened; it does not confirm a luteal phase capable of sustaining early pregnancy, which ideally sits above 30 nmol/L.
Environmental oestrogen reduction. Kirkpatrick treats this as structural, not optional. BPA from plastic food containers, synthetic fragrances in personal care products, pesticide residues concentrated in animal fats: these add to the body’s total oestrogen processing load. She recommends implementing changes gradually over months (swap plastic containers for glass, choose fragrance-free cleaning products, go organic on animal products first) rather than attempting an overwhelming overhaul.
Is Healthy Hormones Worth Reading?
Read this if you have cycle symptoms you’ve normalized (painful periods, PMS, irregular cycles, persistent bloating), if you’ve been given a PCOS or endometriosis diagnosis and want to understand the dietary and lifestyle picture, or if your appetite and weight feel disconnected from your effort and you haven’t looked at the hormonal layer yet.
Skip it if you’re looking for a clinical textbook with systematic review citations (try Aviva Romm’s Hormone Intelligence instead), or if you need a structured weight loss plan rather than a hormonal health framework.
One caveat: This is a 2017 book from an Australian naturopath, and some of the supplement dosing ranges are wide enough that self-implementing without a practitioner is genuinely tricky. Kirkpatrick is consistent about directing readers toward naturopath supervision for complex cases, which is the right call. The book is strongest as a primer that gives you enough clinical literacy to ask better questions, not as a standalone treatment protocol.
