Healthcare is undergoing one of the biggest transformations in modern history.

In this episode of the Livelong Podcast, Rachel Lehmann-Haupt speaks with Dr. Hillary Lin, a Stanford-trained physician, entrepreneur, and co-founder of CareCore, about how AI, personalized medicine, and new care models are reshaping the future of health.

For decades, the healthcare system has been built around treating disease after it appears. But a new generation of clinicians and entrepreneurs are working to build something different: a system focused on prevention, longevity, and individualized care.

Dr. Lin explains how new infrastructure platforms like CareCore are helping doctors deliver personalized medicine at scale by integrating labs, prescriptions, pharmacy fulfillment, and patient data into a single system.

We also explore the promises and risks of AI in healthcare, the difference between longevity hype and real science, and what patients should understand as medicine moves into a new era.

What You’ll Learn:

 ✅ Why healthcare is shifting from reactive medicine to longevity care

 ✅ How AI may transform personalized medicine

 ✅ What infrastructure is needed to scale longevity healthcare

 ✅ The difference between longevity hype and evidence-based medicine

 ✅ How clinicians and patients can navigate the next era of healthcare

If you’re curious about where healthcare is heading — and how it may change the way we live and age — this conversation offers a fascinating look at the future.

So many women hit midlife and feel like something is “off.”  Their moods go up and down, sleep shifts, and energy levels decrease. And when they try to get answers, often they’re dismissed or told everything is normal.

In this episode of the Livelong Podcast, Dr. Jessica Shepherd — board-certified OB-GYN, menopause expert, Chief Medical Officer at Hers, and author of Generation M — joins Rachel Lehmann-Haupt in a conversation about why women lose trust in their bodies, and what’s actually happening during perimenopause and menopause.

We talk about the real connection between hormones, brain health, and emotional changes — and why so many women are taught to override their instincts instead of listening to them.

This conversation is about reclaiming your voice, understanding your body, and knowing when to push back.

Because you’re not crazy — you just haven’t been given the full picture.

What You’ll Learn

 ✅Why women stop trusting their bodies in midlife

 ✅ The emotional and neurological impact of menopause

 ✅ What’s often dismissed — but shouldn’t be

 ✅ The gap in care for women, especially women of color

 ✅ How to advocate for yourself in the healthcare system

 ✅ Why community is critical for long-term health

Why are we still putting women in this small box and just shrinking and ‘pinking’ male protocols?”

With the Livelong Women’s Health Summit in two weeks, we’re introducing you to some of our amazing experts. Dr. Stacy Sims, an exercise physiologist, nutrition scientist, and author, joined Livelong’s Tiffany Nieslanik on a Q&A call in the Women’s Health Circle group to explore why the fitness advice you’ve been following for your entire life is built on male bodies.

The advice works… but only until our hormones don’t.

They explore:

✅ When hormone shifts really begin

✅ Why your strength just disappeared overnight

✅ When long cardio and light weights stop cutting it

✅ What training moves the needle at what age

✅ Where hormone therapy helps—and where it gets oversold

✅ Why do you see strength training as a chore?

✅ The under-eating problem, GLP-1s, and chasing a smaller body

Diving deep into important topics for functional aging, the risks of trying to lose ‘those 10 vanity pounds,’ GLP-1s for weight loss, changing your strength protocol in response to declining estrogen, and the supplement that benefits everyone, it’s a conversation that will benefit everyone

Menopause is finally getting the attention it deserves, but the science is still widely misunderstood, even by the doctors treating us. We're bringing one of the most trusted voices in women's hormonal health into the Livelong Women's Circle for a live conversation you won't want to miss.

Dr. Mary Claire Haver, OB-GYN and bestselling author of The New Menopause and The New Perimenopause, will join us to go deeper on what the hormonal transition years actually mean for your brain, metabolism, and long-term health.

At the end of the event, we'll save space for live Q&A from the audience, but please note that Dr. Haver cannot answer specific, personal medical questions during this event.

Dr. Mary Claire Haver will also be joining us in person at the Livelong Women's Health Summit in San Francisco, April 17th + 18th. Join Dr. Haver and dozens of other experts as we discuss the future of women's health and what it means to age well.

Perimenopause can start earlier than most women think — even in your 30s. And the symptoms aren’t just hot flashes.

In this episode of the Live Long Podcast, host Rachel Lehmann-Haupt sits down with Heidi Davis, CEO of Peri (a purpose-built wearable and app using AI to track perimenopause symptoms), to break down what’s happening in the body, what women often miss, and why tracking your symptoms can be a game-changer for your healthspan.

You’ll learn:

✅ The biggest misunderstanding about perimenopause (and why it starts earlier than you expect)

✅ The difference between menopause vs. perimenopause (and why age 51 is not the full story)

✅ Why symptoms like anxiety, sleep disruption, irritability, and brain fog are often ignored early on

✅ How shifting hormones impact the brain, heart, metabolism, cholesterol, weight, and even dental health

✅ Why the “just suffer through it” model can raise long-term risk (including cardiovascular disease)

✅ How symptom tracking helps create a personalized journey—including lifestyle, resistance training, and hormone therapy support

✅ What to watch for in the supplement world: snake oil vs. human-trial-backed ingredients

✅ The most overhyped trend right now (Heidi’s take): the weighted vest

✅ The mindset shift that matters most: your data is your power

This conversation is about more than managing symptoms — it’s about using a critical window in your 40s to protect long-term health, stay sharp, and live better for longer.

Join Us Live: Livelong Women’s Health Summit (San Francisco)

Heidi Davis will be speaking at the Livelong Women’s Health Summit, April 17–18, 2026, in San Francisco — alongside Jane Fonda, Dr. Mark Hyman, Dr. Stacy Sims, Dr. Dean Ornish, and many more.

In this week's podcast, Erin sits down with Dr. Gillian Goddard, a board-certified endocrinologist at Park Avenue Endocrinology and Nutrition and the author of the forthcoming book The Hormone Loop, to cut through the hype around GLP-1 medications like Ozempic and Mounjaro—and get to what the science actually says about their role in healthy aging.

Drawing on more than 15 years of clinical experience and the latest research on metabolic disease, Dr. Goddard explains why these drugs are far more than a weight loss shortcut, and what we still need to learn before calling them a true longevity medication.

They explore:

✅ The GLP-1 origin story

✅ Why metabolic dysfunction is the real driver of heart disease, stroke, and (probably) dementia

✅ Why doing everything "right" might not be enough

✅ What two major dementia trials revealed about GLP-1s

✅ The nuanced truth about muscle loss 

✅ Who makes the best candidate for GLP-1s

✅ The misconception around "microdosing" GLP-1s 

✅ The one daily habit Dr. Goddard swears by for her own longevity 

GLP-1s are not a miracle for everyone—but they may be closer to one than we think for the right person, at the right time.

Preventing cognitive decline can be something you actively influence. 

In this week’s podcast, Erin sits down with Dr. Jennifer Buczyner, preventive neurologist at the Atria Institute, to explore how lifestyle, diet, exercise, and brain training can help protect your mind—and your independence—well into later life. 

Drawing on cutting-edge research, her experience with patients across ages, and the emerging field of preventive neurology, she unpacks strategies to reduce dementia risk, optimize brain health, and embrace aging with clarity and ease.

They explore:

✅ Why genetics is not destiny: how lifestyle can counteract risk if you have the Alzheimer’s gene (APOE4) 

✅ Why 45% of dementia is preventable with lifestyle and risk factor modifications

✅ The surprising connection between oral health and brain plaque

✅ The role of sleep as a protected, non-negotiable part of brain health

✅ Why processing speed and neuroplasticity matter more than rote memory training

✅ Practical, actionable steps for diet, exercise, and sleep that really make a difference

✅ Why knowing your genetic risk of Alzheimer’s is actually empowering 

Memory loss is not inevitable. Instead, it asks you to see urologic health as a reflection of muscle integrity, blood flow, and lifestyle, and something that deserves earlier, more serious attention.

“Heart disease is the number one killer of women. Sometimes the first symptom isn’t chest pain…. It’s urinary change.”In this episode, Livelong’s Erin Hunter talks to Aleece Fosnight, Medical Advisor at Aeroflow Urology, and a board-certified PA specializing in urology and women’s health, about the intersection between urologic health and aging.Rather than dismissing urgency, leakage, or recurrent “UTIs” as inevitable, Fosnight reframes them as symptoms that are shaped by hormone loss, pelvic floor mechanics, vascular health, nervous system function, and even bowel habits.Less understood is the fact that changes in blood flow — which can be early signs of cardiovascular issues, dementia, and stroke risk — are felt by the bladder before the heart, and Dr. Fosnight breaks down screening protocols to stay on top of bladder and cardiovascular health.They explore:✅ Bladder leakage is common, but not normal.✅ Hormone loss as a precursor to muscle weakening✅ Why birth control is often the best treatment for perimenopause✅ Why more than half of midlife “UTI” symptoms aren’t actually infections✅ How bladder changes might predict cardiovascular conditions✅ The long-term effects of constipation on bladder health✅ The underused first line of care to address early-onset bladder conditionsThe conversation challenges your reflex to blame age on bladder problems. Instead, it asks you to see urologic health as a reflection of muscle integrity, blood flow, and lifestyle, and something that deserves earlier, more serious attention.

For Dr. Sophia Yen, a Stanford adolescent medicine specialist and Pandia Health co-founder, hormone therapy isn’t a short-term treatment…it’s lifelong health insurance.

In this episode, Livelong’s Erin Hunter sits down with Yen for a deep dive into menopause, perimenopause, hormones, birth control, and how estrogen loss rewires the body, driving visceral fat gain, cardiovascular risk, bone loss, and metabolic dysfunction.

Dr. Yen also challenges the playbook (such as the “10-year window” and compounded hormones) and argues that much of modern menopause care is based on outdated fear, not current evidence.

They explore:

• Why menopause triggers visceral fat, cholesterol spikes, and arterial stiffening (and why this isn’t just “aging”)
• The case for lifelong hormone therapy
• Why birth control is often the best treatment for perimenopause
• The misunderstood “10-year window” for starting HRT
• The overlooked role of metformin in midlife metabolism and diabetes prevention
• Protein-forward diets and the 60–60–60 longevity rule

We hope this conversation explains more about the function of hormones and pushes you past thinking about symptom management.“You’re going to find this estrogen patch on my dead body.”

Fertility isn’t just about getting pregnant.
It’s one of the earliest and most revealing indicators of your overall health.
In this episode, reproductive endocrinologist Dr. Natalie Crawford reframes fertility as a vital sign — one that reflects your hormones, metabolic health, brain function, and long-term longevity.
From ovarian reserve to perimenopause to the misunderstood “biological clock,” we explore how reproductive health offers powerful insight into what’s happening across your entire body — often years before bigger shifts occur.
Dr. Crawford also shares how becoming a fertility patient herself reshaped the way she practices medicine — and why women deserve clearer data, earlier conversations, and more proactive care.
This is not a conversation about urgency or fear.
It’s about awareness and agency.
Because fertility isn’t a moment.
It’s a health signal for life.
