Dr Mary Claire Haver
OBGYN, menopause specialist and founder of the Galveston Diet. The doctor who is telling 1.2 billion women what the medical system has failed to: menopause is inevitable. Suffering is not.
Dr Mary Claire Haver is a board-certified OBGYN and menopause specialist based in Texas. She completed her residency in 2002 and spent over 15 years in clinical practice before realising there was a profound gap in how medicine understood and treated women going through perimenopause and menopause. She went back to school, trained in culinary medicine at Tulane University, and developed the Galveston Diet, an anti-inflammatory nutrition programme designed specifically for women in hormonal transition. Her social media following grew to over 2 million as women recognised their own experiences in what she was describing. She founded the Mary Claire Wellness Clinic in 2021 and published The New Menopause in 2024. She is one of the most important voices in women's health today.
Watch the Interview
This Diary of a CEO interview with Steven Bartlett from December 2023 covers the full picture of perimenopause and menopause. What it is, why it affects every organ system in the body, why the medical system has consistently failed women going through it, what the research actually shows about hormone replacement therapy, and what women can do right now through nutrition, exercise and sleep. One of the most comprehensive and accessible conversations on this topic available anywhere.

What She Covers in This Interview
Haver opens with something that will feel familiar to many women. She spent 15 years as a practising OBGYN doing her very best for her patients, and still she was not giving the women in perimenopause and menopause the care they needed. Not because she did not care. Because nobody had taught her how. Senior residents in her training had a quiet nickname for these patients: WW. Whiny women. She tells that story not to shame the profession but to name the problem honestly. Those women were not whining. They were experiencing up to 70 documented symptoms of hormonal transition that medicine simply had no framework to address.
What this interview illuminates is how many layers of difficulty a woman faces at this time of her life. Medical training on menopause remains inadequate. Research funding is almost nonexistent relative to its scale. A misrepresented study from 2002 frightened both doctors and patients away from treatments that could genuinely help. And underneath all of it, the quiet but persistent cultural message that aging women should not take up too much space, should not complain, should carry on. That message has cost too many women too much for too long.
The Scale of the Problem
Right now approximately a third of the female population of the world is in perimenopause, menopause or postmenopause. That is 1.2 billion women. In 2023, 85% of women reported menopausal symptoms to their healthcare provider. Only 10.5% received any treatment or therapy. A woman today is more likely to be prescribed an antidepressant for her menopause than hormone therapy.
Dr Mary Claire Haver, Diary of a CEO, December 2023
Perimenopause can begin 7 to 10 years before menopause itself, meaning symptoms can start in a woman's mid to late thirties. Menopause, defined as one year after the last menstrual period, occurs on average at age 51 in the UK and US. Postmenopause is the rest of a woman's life. The hormonal changes that drive all three stages affect every organ system in the body because estrogen receptors exist in every organ system. This is why the symptom list runs to approximately 70 documented effects and why so many women are misdiagnosed or dismissed.
What Menopause Actually Does to the Body
For a long time menopause was reduced to its most visible symptoms. Hot flashes. Night sweats. The assumption that it was a brief inconvenience rather than a whole-body transition. What the research now shows is far more wide-ranging, and understanding it is not frightening. It is freeing. Because once you know what is happening and why, you can begin to do something about it.
If your cholesterol has gone up or your blood sugar has shifted and nothing in your diet or routine has changed, this may be why. Menopause independently increases the risk of cardiovascular disease and diabetes. These are not lifestyle failures. They are hormonal changes, and they are worth taking seriously and addressing with the right support.
If you have felt unlike yourself, more anxious than usual, lower in mood, or struggling in ways that are hard to explain, please know this is one of the most commonly reported and least commonly addressed aspects of this transition. Estrogen has a profound protective effect on the brain. When it declines, mood, concentration and emotional resilience can all be affected. This is not a personal failing. It is biology. And it is treatable.
Many women notice changes in their strength and body composition during this time, even when nothing about their routine has changed. In the first 10 years of menopause, muscle mass can decline significantly and bone density follows. The encouraging news is that this is one of the areas where targeted action makes a real and meaningful difference. Building strength now is one of the most loving things you can do for your future self.
Frozen shoulder, generalised joint pain and inflammation are now recognised as common menopause symptoms. Estrogen's anti-inflammatory properties protect connective tissue. When it declines, women develop adhesive capsulitis and other musculoskeletal conditions that most physicians do not associate with hormonal change.
Recurrent urinary tract infections, discomfort and changes in intimacy are common during menopause and are rarely spoken about openly enough. They are caused by estrogen decline affecting delicate tissue, and they are very treatable. Vaginal estrogen is safe, effective and appropriate for almost all women, including those with a history of breast cancer. If you have been suffering with this quietly, please know it does not have to continue.
Waking at 3am with a racing mind. Walking into a room and forgetting why you came. Struggling to find words that used to come easily. These are not signs of something wrong with you. They are documented hormonal effects experienced by millions of women. Sleep in particular is foundational. When it improves, almost everything else begins to improve with it.
The Women's Health Initiative and the HRT Myth
In 2002 a major US study called the Women's Health Initiative was stopped early after researchers reported an increased risk of breast cancer in women on combined hormone replacement therapy. The press conference announcement set the world on fire. Doctors stopped prescribing HRT overnight. The fear has persisted for over two decades.
Haver dismantles this carefully. The study enrolled women with an average age of 63 to measure cardiovascular effects. It was not designed to study perimenopause. The absolute risk increase in the combined estrogen and progestin arm was one additional breast cancer case per thousand women per year. The relative risk figure of 25% that generated the headlines was accurate but deeply misleading in isolation. The estrogen only arm of the same study showed a reduction in breast cancer risk and a 40% reduction in mortality.
The study has since been extensively reanalysed. The current scientific consensus is that for the vast majority of women, beginning hormone therapy in perimenopause or within the first 10 years of menopause significantly reduces the risk of cardiovascular disease, diabetes and dementia. Estrogen is better at prevention than cure. Starting early is the sweet spot.
Women on HRT have a lower all cause mortality. The thought that estrogen causes breast cancer is the worst thing that came out of that study, because it is not true.

The Toolkit — What Actually Helps
Haver is emphatic that hormone therapy is one tool in a broader toolkit, not a cure-all. Here is what the evidence supports:
The single most important exercise change for women in menopause. Muscle mass determines longevity, insulin resistance, bone density and functional independence as you age. Haver's message is direct: strength over skinny. This is the time to build, not maintain. Creatine supplementation combined with resistance training shows meaningful gains in muscle mass in postmenopausal women.
Most women are getting around 12 grams of fiber per day. The minimum recommended intake is 25 grams. Fiber slows glucose absorption into the bloodstream, feeds the gut microbiome, reduces chronic inflammation and supports cardiovascular health. Haver prioritises it above almost everything else in nutritional counselling. Avocado, chia seeds, nuts, berries, cruciferous vegetables, apples and legumes are the most accessible sources.
Around 85% of Haver's menopausal patients are vitamin D deficient, not just low but clinically deficient. Vitamin D functions as both a vitamin and a hormone with receptors throughout the brain and body. Deficiency is linked to hypertension, diabetes, stroke and depression. Gut absorption of vitamin D decreases with age. Regular testing and supplementation where needed is one of the most impactful low-cost interventions available.
Protein intake needs to increase significantly in menopause to support muscle maintenance. Haver has moved away from her original lower-protein Galveston Diet ratios toward substantially higher protein targets based on emerging research into muscle mass and aging.
Haver treats sleep disruption as the first priority in any patient consultation. Nothing else works properly when sleep is broken. Cortisol spikes, insulin resistance increases and every symptom worsens. If hormonal therapy is appropriate, returning estrogen levels often resolves sleep disruption quickly and everything else improves with it.
Estrogen is a powerful anti-inflammatory hormone. Its loss accelerates systemic chronic inflammation. Reducing added sugar intake, prioritising healthy fats and eating an anti-inflammatory diet directly compensates for some of estrogen's lost protective effect. Haver recommends keeping added sugar below 25 grams per day and focusing on what to add rather than what to restrict.
You Are Not Crazy. You Are Not Alone.
If you have found this page because something has changed and you cannot quite explain it. Because you are not sleeping. Because you feel unlike yourself. Because you have been to a doctor and left with more questions than answers, or been told it is stress, or been handed a prescription that did not feel right. We want to say something clearly and without hesitation:
What you are experiencing is real. It has a name. It has causes. And there are things that genuinely help.
For generations, the experience of perimenopause and menopause has been met with silence, dismissal or shame. Women have been told their symptoms were in their heads. They have been labelled difficult, emotional or unstable at exactly the moment their bodies were going through one of the most significant hormonal transitions of their lives. Many have suffered quietly, not wanting to be a burden, not knowing where to turn, not realising that what they were feeling was shared by millions of women around the world going through exactly the same thing.
That silence has a cost. Relationships strained by symptoms neither partner understood. Careers affected by brain fog that was never identified or supported. Health consequences that built quietly over years because the right intervention was never offered. None of this was inevitable. None of it was anyone's fault. And none of it has to continue.
If you are a partner, a friend, a son or a daughter of someone going through this: your patience matters more than you know. You do not need to have all the answers. You do not need to fix it. Listening, staying present and trying to understand goes further than most people realise. The women in your life are not asking you to become medical experts. They are asking to be seen and believed.
Asking for help is not a weakness. Seeking information is not overreacting. Finding a doctor who truly understands this subject and takes it seriously is not an unreasonable expectation. It is something every woman deserves.
Finding specialist support
We are building a directory of menopause-informed healthcare providers and resources from around the world. Doctors, clinics and organisations that approach this subject with the depth, knowledge and compassion it deserves.
If you know of a provider, clinic or resource that has genuinely helped you or someone you love, we would be grateful to hear about it. Every recommendation helps someone else find the support they need.
Share a recommendation with us →In the meantime Dr Mary Claire Haver maintains a list of recommended menopause-informed providers on her website at maryclairewellness.com. The Menopause Society also holds a directory of certified practitioners at menopause.org. In the UK the British Menopause Society maintains a directory of accredited specialists at thebms.org.uk.
Menopause is inevitable. Suffering is not. And you do not have to navigate it alone.
Why This Matters for Everyone
Menopause touches everyone. Every person reading this either will go through it, loves someone who will, or is living alongside someone who already is. When partners, friends and family understand what is happening, relationships do not just survive this transition. They can grow through it. When they do not understand, the silence between people who care about each other can become very loud.
There is also a connection this site holds close. The endocrine system that estrogen decline disrupts in menopause is the same system affected by PFAS, phthalates, atrazine and other environmental chemicals throughout a woman's life. Chemical exposure does not only matter in the reproductive years. It matters across an entire lifetime of hormonal health. The research is still growing, but the threads connect. Which is why hormonal health in all its forms belongs here.
Every woman going through this deserves to be heard, believed and supported. Every person who loves a woman going through this deserves to understand what she is experiencing. That conversation starts with knowledge. And knowledge starts here.
Menopause is inevitable. Suffering is not.
