• Season 3, #23 - Dr Nerys Astbury Why We Gain: Understanding Obesity

  Nerys is a human nutrition scientist with a strong interest in clinical trial methodology and evidence-based medicine. Nerys has worked at the University of Manchester and the New York Obesity Research Center at Columbia University in New York City. She is currently Associate Professor in diet and obesity in the Health Behaviours Team at the University of Oxford. Her main interests are how dietary manipulations impact weight management and the regulation of energy intake. She leads a programme exploring the effect of dietary interventions and weight management before, during and after pregnancy can influence health of mothers and their children. Nerys explains why maintaining a healthy weight is so important. Obesity is a major global health concern, increasing the risk of many chronic diseases and reducing quality of life. Yet today, we are constantly bombarded by clever marketing of unhealthy, ultra-processed foods. Perhaps it’s time to focus on eating for quality rather than quantity. Nerys also explores how a healthy weight supports fertility, pregnancy, and the health of our children, as well as the challenges of weight gain as we age — for both men and women. We discuss the many approaches people take to lose weight — from diet plans and exercise to weight-loss medications — and emphasise the importance of finding a sustainable nutrition plan that truly works for you.  Date of episode recording: 2025-11-03 Duration: 00.58.44 Language of episode: English Presenter:Professor Joyce Harper Guests: Dr Nerys Astbury Producer: Joyce Harper Podcast Owner: Joyce Harper

• Season 3, #21 Amanda Thebe World Menopause Day Special: Navigating the Wild West of Menopause.

  Navigating the Wild West of Menopause Amanda Thebe is a Fitness and Women’s Health Expert. She is the author of the Amazon best-selling book, Menopocalypse: How I Learned to Thrive During Menopause and How You Can Too! With nearly 30 years of experience in the fitness industry, Amanda is a highly-regarded expert on women’s fitness and health. She is the co-founder and Chief Wellness and Branding Officer at Nyah Health, a complete healthcare solution for menopausal women in Canada. She is Canada’s first menopause workplace educator. She is a popular guest on podcasts, radio, TV and online summits, and she brings a refreshing humour and no-nonsense approach to subjects usually shrouded in shame. Her exercise workouts, health and fitness tips have been featured in Oprah, Shape, Prevention, Health Line, CBC Radio, Global News Canada, The Doctors and many more. https://amandathebe.com/ Instagram: @amanda.thebe Are you ready for this? Amanda and Joyce leave no stone unturned. They begin with an honest, evidence-based discussion of hormone therapy, aligning with the guidance from menopause societies. Together, they explore why some influencers and even doctors go rogue, creating two very different camps. One promotes hormone therapy as a preventative medicine, which would suggest that all women should take it. The other, supported by the menopause societies, recognises its proven benefits: hormone therapy can be effective for hot flushes, night sweats, some vaginal and vulval issues, and possibly certain psychological symptoms—but it is not a preventative medicine. It has an important role, but it is not for everyone. Amanda shares how she struggled with hormone therapy, and how her doctor astonishingly suggested a hysterectomy so she could take oestrogen-only therapy. Joyce and Amanda explain why that advice was, frankly, insane. They also stress that menopause is not a hormone deficiency disorder. The conversation moves on to the clever marketing aimed at women of a certain age. From supplements to face creams, shampoos to chocolate, Amanda and Joyce discuss how the placebo effect can be powerful—many women truly believe these products make them feel better. This year’s theme for World Menopause Day is lifestyle medicine. Amanda highlights how vital lifestyle is for health but also points out the misleading claims women are bombarded with—from weighted vests to warnings that postmenopausal women should avoid cardio and only lift heavy weights. The message here is clear: let’s make lifestyle sexy by embracing nourishing food and regular exercise. In the wild west of menopause, women are often criticised for calling out misinformation. But this is not about women failing to support each other—it is about challenging medical inaccuracies. Their message is simple: beware of anyone trying to sell you something, whether it’s a prescription, a supplement, or even “menopause chocolate.” Trust the advice from the menopause societies. And, as Joyce jokes, hopefully they won’t get sued for saying so! Date of episode recording: 2025-09-11 Duration: 01.22.57 Language of episode: English Presenter: Professor Joyce Harper Guests: Amanda Thebe Producer: Joyce Harper Podcast owner: Joyce Harper

• Season 3, #Episode 20 Professor Neil Gittoes: Understanding osteoporosis

  Professor Neil Gittoes is Consultant Endocrinologist at the Queen Elizabeth Hospital, Birmingham and Honorary Professor of Endocrinology at the University of Birmingham. He graduated from the University of Birmingham with honours in medicine and anatomical studies and has a PhD in molecular endocrinology. Neil is recognised nationally and internationally for his work in metabolic bone diseases including osteoporosis, vitamin D deficiency and disorders of calcium homeostasis. He has co-authored recent international guidance on management of parathyroid diseases and UK guidance on osteoporosis. Neil was awarded the Goulstonian Lectureship at the Royal College of Physicians, London and has had many key roles, including being the current chair of the Royal Osteoporosis Society. https://theros.org.uk/Did you know you can check your risk of osteoporosis with a quick online tool from the Royal Osteoporosis Society? Just pop onto their website and try the risk checker. If it shows you’re at high risk, it’s worth speaking to your doctor, who may suggest a bone density scan. The good thing is that osteoporosis is largely preventable. Neil talked us through how our bones change as we get older. Half of all women over 50 will break a bone because of osteoporosis, and so will one in five men. Genetics play a big part—about 70 to 80% of our risk comes from our genes—so it’s important to know your family history. But lifestyle matters just as much. Doing regular weight-bearing exercise, cutting down on alcohol, not smoking, keeping vitamin D levels up, and eating enough protein and calcium can all help protect your bones. The tricky thing about osteoporosis is that it’s a silent disease—you don’t feel it happening. But the good news is that there are effective treatments. Some are one-off or short courses, and you don’t need to be on lifelong medication. We also touched on whether women should take HRT to prevent osteoporosis, and Neil had some interesting views. He also explained why getting a diagnosis of osteopenia isn’t something to panic about. Another key point Neil made is how important lifestyle is before the age of 25—that’s when we reach our peak bone mass. So if there’s one message for younger people, it’s that the choices you make in your teens and twenties, especially around exercise, can shape your bone health and your risk of chronic conditions later in life. Date of episode recording: 2025-09-26 Duration: 01.04.57 Language of episode: English Presenter: Professor Joyce Harper Guests: Professor Neil Gittoes Producer: Joyce Harper

She lives on Sydney’s Northern Beaches, where she writes, teaches, swims in the ocean year-round, and turns complex neuroscience into practical tools and accessible stories. https://drsarahmckay.com/ Instagram: @drsarahmckay Most of us know someone living with dementia or Alzheimer’s. In this podcast, we separate fact from myth: what are the symptoms, can we reduce our risk, are women more vulnerable to Alzheimer’s, and much more. One of the most striking findings is that around 45% of dementia cases are considered preventable. The choices we make around lifestyle—nutrition, exercise, limiting alcohol, staying mentally and socially engaged, and looking after our hearing and eyesight—can all play a role, according to major dementia and Alzheimer’s organisations. We also address some of the claims circulating on social media about menopause and dementia/Alzheimer’s —for example, the idea that hormone therapy can prevent dementia. Sarah sets the record straight: unfortunately, this isn’t true. She has faced criticism online for challenging this myth, but calling out misinformation is not about women undermining women; it’s about ensuring we share facts rather than perpetuate inaccuracies. That said, research does suggest that frequent hot flushes may be linked to an increased risk. There’s still much more to learn, but what we do know is already powerful. By understanding the evidence on dementia and Alzheimer’s today, we can start taking steps to lower our risk.  Date of episode recording: 2025-09-10 Duration: 01.20.12 Language of episode: English Presenter: Professor Joyce Harper Guests: Dr Sarah McKay Producer: Joyce Harper
