The Thyroid (and Hormone) Fixer Podcast: Thyropause, Menopause, Metabolism and How to Fix It

What if Alzheimer's doesn't begin when you start forgetting things, but decades earlier, with your blood sugar, your waistline, and your hormones? In this episode, I'm joined by Dr. David Perlmutter, Board-Certified Neurologist and author of Grain Brain and his new book, Brain Defenders, to unpack why your brain's future is something you can influence. We talk about microglia, the brain's own immune cells, how they shift from protecting your brain to damaging it, and why chasing beta amyloid may be missing the bigger picture. We also get into how thyroid hormone, especially T3, fuels the mitochondria that help keep those immune cells supportive. We look at why the drop in estrogen during perimenopause may help explain why two-thirds of Alzheimer's patients are women. Dr. Perlmutter shares where he stands on hormone replacement therapy and testosterone and what the research says so far about GLP-1 medications and brain health. He also names the labs he wants everyone in their 30s, 40s, and 50s to know, including fasting insulin, A1C, and homocysteine. What you'll learn: Why Alzheimer's may begin decades before memory loss shows up Why Dr. Perlmutter says carrying the APOE4 gene variant means predisposed, not predetermined What microglia are and how they shift from supportive to destructive How blood sugar, gut inflammation, and head trauma can all affect your brain's immune cells How thyroid hormone and your mitochondria work together to support brain energy Why falling estrogen during perimenopause may put women's brains at greater risk Where Dr. Perlmutter stands on hormone replacement therapy and testosterone What the research says so far about GLP-1 medications and the brain Tune in to learn how to start protecting your brain now, long before any symptoms show up.

Gut health is about far more than bloating and constipation. In this episode, I’m joined by Laura Frontiero to unpack the overlooked ways gut dysfunction can show up, from fatigue and brain fog to skin issues, joint pain, sleep problems, and thyroid challenges. We also talk about why common gut protocols don’t always work and why the order in which you address gut health matters. We connect the dots between the gut, thyroid function, nutrient absorption, hormone clearance, toxins, infections, and chronic stress. Laura also breaks down the four areas she looks at when working with gut health and why supporting the body before jumping into probiotics or other protocols can make such a difference. What you’ll learn: Why gut problems don't always cause digestive symptoms Why probiotics aren't always the best place to start How gut health and thyroid function influence each other The connection between toxins and nutrient deficiencies What chronic stress has to do with gut restoration Why digestion and stomach acid matter for thyroid health How hormone clearance is connected to the gut Why the order of your approach matters Tune in to learn how to recognize the less obvious signs of gut dysfunction, understand the connection between your gut and thyroid, and rethink the way you approach gut health.

What if the best biohacks are actually the simplest ones? In this episode, I’m breaking down the tools I genuinely believe are worth considering, from sleep, strength training, and pain management to cleaner air and water, red light therapy, sauna, and frequency-based technologies. I also talk about where more advanced options like stem cells, exosomes, and PRP fit in, and the question I use to evaluate any biohacking tool: Does it actually help my body function better, or does it just give me more to track? What you’ll learn: Why sleep is the foundation of biohacking Which simple environmental changes can make a difference What makes red light therapy worth considering Why pain relief and mobility deserve more attention Where sauna and frequency technologies fit What I think about regenerative therapies Why strength training may be the ultimate biohack How to know when a biohack is actually worth it If you’ve ever felt overwhelmed by the endless options, gadgets, and advice in the biohacking world, this episode will help you sort through what’s actually worth your time and attention.

What happens when biohacking stops being about improving your health and starts costing you money, creating more stress, and taking you away from your actual life? In this episode, I’m calling out the biohacking bullshit that has gone too far, from endless supplements and peptides to CGMs, cold plunges, expensive devices, whole-body MRIs, biological-age testing, and the pressure to constantly optimize another metric. Just because something is expensive, high-tech, or backed by some scientific mechanism doesn’t mean it is actually solving your problem. I’m not anti-biohacking. I use some of these tools myself. The issue is what happens when we start using the 5% to avoid the 95% that actually matters: sleep, nutrition, movement, muscle, stress, relationships, and addressing underlying physiology. I break down the five questions I want you to ask before spending another dollar on a biohacking intervention and why the ultimate measure of health may have less to do with your readiness score or biological age and more to do with whether you have the energy and freedom to enjoy your life. What you’ll learn: The hidden costs of taking biohacking too far How fear can drive unnecessary health spending When health tracking starts creating more stress than value What to consider before spending thousands on peptides, devices, or testing Why more data doesn't automatically mean better health How optimization can start interfering with food, family, and everyday life Why the basics still matter more than the latest biohacking trend The five questions to ask before trying your next biohack If you’ve been caught up in the pressure to constantly optimize your health, this conversation will give you a different way to think about what is actually worth your time, money, and attention.

What does the research actually tell us about T2, the often-overlooked thyroid hormone? In this episode, I break down the science behind T2, from animal research on metabolism and fat browning to the limited human studies available, including a 2011 study that found changes in resting metabolic rate and body weight. I also share the results of our own 14-week trial involving 14 women with different thyroid and hormonal profiles. We look at what happened, what surprised me most, how the findings influenced our dosing approach, and where more research is still needed. What you’ll learn: Why researchers are interested in T2 and metabolism What animal studies have shown about T2 and fat browning What the limited human research tells us What happened in our 14-woman trial Why thyroid function made some of the results particularly interesting What the findings changed about our dosing approach What we still need to learn about T2 There’s a lot to be curious about when it comes to T2, but the research matters. Tune in as I walk through what we know, what we’ve seen firsthand, and what still needs to be studied. Resources: Grab your Thyroid Fixer here: https://betterlifedoctor.com/ New here?
