Dr. Lauren is a researcher and science communicator specializing in female physiology, exercise, and nutrition, and a former seasoned fitness professional with extensive hands-on experience helping hundreds of women in all stages of life. She is a co-owner of the MASS Research Review, which helps bridge the gap between cutting-edge research and practical fitness strategies for coaches and trainers. Lauren works to dismantle fitness and nutrition myths perpetuated without a scientific basis by fact checking claims made by online influencers. Lauren's scientific expertise and real-world experience as a fitness professional helps practitioners provide evidence-based recommendations to women in all stages of life. If you use social media for any of your health advice, this is an episode you need to hear. Joyce and Lauren explore how health and fitness misinformation spreads online — and why, once it takes hold, it can be surprisingly hard to “unlearn”. They break down how to judge the quality of evidence, including the differences between mechanistic studies, observational research and human clinical trials, and why correlation is not the same as causation. They also tackle some of the major myths Lauren works hard to debunk: fasted training, protein obsession, weighted vests, grip strength, collagen and creatine hype, vibration plates, and the way supplements are often marketed with exaggerated claims. Throughout, Lauren explains what the evidence does (and does not) support — and why mastering the basics matters far more than chasing the latest trend.

Our Favourite Drug Professor David Nutt is a psychiatrist and the Edmond J. Safra Professor of Neuropsychopharmacology in Imperial College London and Chief Research Officer of Awaknlifesciences. He is currently Founding Chair of the charity DrugScience.org.uk and has been president of the European Brain Council, the BAP, BNA, and ECNP. David has published 35 books and over 1000 research papers that define his many landmark contributions to psychopharmacology including GABA and noradrenaline receptor function in anxiety disorders, serotonin function in depression, endorphin and dopamine function in addiction and the neuroscience and clinical utility of psychedelics.

Some of his research has been made into films e.g. https://www.imdb.com/title/tt8661404 on Netflix and https://www.bbc.co.uk/programmes/m000w7bq on the BBC and a play https://www.goodreads.com/book/show/43887749-all-you-need-is-lsd . He broadcasts widely to the general public on pharmacology and psychiatric matters, has over 60k followers on twitter and has his own very popular podcast (https://podcasts.apple.com/gb/podcast/the-drug-science-podcast/id1474603382 . Some of his key books are: Drugs Without the Hot Air: Minimising the Harms of Legal and Illegal Drugs Drink?: The New Science of Alcohol and Your Health Nutt Uncut Brain and Mind Made Simple Cannabis (Seeing through the Smoke): The New Science of Cannabis and Your Health Psychedelics: The Revolutionary Drugs That Could Change Your Life — A Guide from the Expert David Nutt’s landmark Lancet paper in 2010 compared 20 legal and illegal drugs across 16 types of harm and found that, overall, alcohol was the most harmful drug. 

Large studies show that among people aged 15–49, alcohol is one of the leading risk factors for death and disability worldwide, and in England it is the biggest risk factor for ill health, disability and death in this age group. Yet drinking is still normalised in today’s society. There is some good news: young people are, on average, drinking less than previous generations. At the same time, older adults are now the most likely to exceed the UK low-risk guidelines. From this podcast we hope people can make more informed choices about why they drink alcohol – and feel encouraged to reduce their drinking to safer levels.

Pauliina Damdimopoulou is a Professor of Reproductive Biology at the Department of Women's and Children's Health at the Karolinska Institute in Stockholm, Sweden. With over 15 years of experience in endocrinology, reproductive biology and toxicology, Pauliina’s team are investigating the effects of chemicals on female fertility.

Her ambition is to generate evidence-based information on the risks of chemical exposures and pharmaceutical treatments to human ovaries and oocytes, and to thereby contribute to the development of a chemically safer society. She co-leads the Environmental Endocrinology Focus Area of the European Society of Endocrinology. Instagram: @damdimopoulou_lab https://ki.se/en/people/pauliina-damdimopoulou 

Do you know how many untested or minimally tested chemicals there are in our environment, how they are tested, and how they can affect our health, fertility and the health of our children? Pauliina knows the answers to these questions. And it’s really worrying to hear her talk about this.
 
She said we should be upset, we should be angry, and we need to act. Plastics are a major issue, and they’re everywhere. But it doesn’t stop there — many of the products we use daily, including make-up, perfume, clothes wash, cleaning products and much more, contain chemicals like phthalates and parabens which can affect our hormones and health. These are all around us, yet we can take steps to reduce our exposure. I hope this podcast gives you the insight and confidence to cut down the chemicals in your life and support your long-term health.

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.

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!

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.

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.

Joyce and Nerina have known each other for over 40 years, since they first met while doing their PhDs — which makes this episode particularly special. Both are deeply passionate about the idea of reclaiming joy. In this conversation, Nerina explores what joy really is. It’s not always easy to define. ChatGPT describes it as a deep feeling of happiness, delight, or contentment that often arises spontaneously — not always triggered by something external. Nerina expands on this, explaining why joy is so essential for both our physical and mental wellbeing. Of course, joy looks different for everyone. We each have to discover what brings us joy in our own way. Nerina argues that joy should be recognised as a priority not just in our personal lives, but also in schools and workplaces — right alongside sleep. This is the final episode in the mini-series on reclaiming joy for 2025. I hope it’s sparked some ideas and inspiration for how you might reconnect with your own sense of joy. I’ll be back with another mini-series on joy and happiness next year — so stay tuned.
