How Much Protein Do You Need? Top Scientists Still Disagree Oct 15, 2026

Show notes

Protein is in everything right now: coffee, chips, cookies, bars. But despite the massive marketing hype, the world’s leading scientists are still debating fundamental questions about how much protein we actually need and how the body uses it. Fresh off the Protein Summit 3.0 at Texas A&M, Dr. Gabrielle Lyon breaks down what top researchers agreed on, why treating protein as a single number is a major mistake, and how to stop falling for "high-protein" health halos in the grocery store.

Dr. Tiffany Moon: Is Anesthesia Safe? What Patients Fear vs. What Actually Happens Oct 13, 2026

Show notes

In this episode, board-certified anesthesiologist, researcher, and former Real Housewives of Dallas star Dr. Tiffany Moon pulls back the curtain on modern medicine, surgical pain management, and the reality of navigating elite academia. From addressing widespread public fears around clinical fentanyl use to detailing why she was branded an "embarrassment" by academic peers for appearing on reality television, Dr. Moon speaks candidly about breaking stereotypes, the gender pay gap in healthcare, and using a massive public platform to advocate for science and mentorship.

What You'll Learn In This Episode:

The Clinical Truth About Fentanyl: Why it is the standard of care for 90% of surgeries, and why post-op patients shouldn't fear becoming addicted.
The Reality TV Fallout: How appearing on The Real Housewives led to institutional blowback—and why she’d do it again.
Leveraging Fame for Science: Turning pop culture visibility into serious advocacy for mentorship, healthcare equity, and closing the gender pay gap.
Shattering Stereotypes: Moving past appearances to run clinical trials, publish randomized controlled studies, and teach the next generation of physicians.

Hormones and Attraction: What We Think We Know vs. What the Science Says Oct 08, 2026

Show notes

Can you tell someone's testosterone or estrogen levels just by looking at their face? Is "jawmaxxing" actually backed by science? In this video, we dive deep into the real science of hormones, physical attraction, and evolutionary biology.

We debunk popular myths around high testosterone, facial masculinity, and ovulation preferences, revealing what the research actually shows about human mate selection. Discover why facial structure isn't a hormone panel, how estrogen impacts skin and collagen as women age, and why physical strength accounts for 70% of perceived bodily attractiveness.

If you want to understand how hormones shape our development—and why muscle is the single most modifiable signal of health and longevity—this episode is for you.

Dr. JJ Thomas: Pain Is an Alarm. Why Your Injury Keeps Coming Back and How To Fix It Oct 06, 2026

Show notes

When you have musculoskeletal pain, the natural instinct is to try and treat it directly. But the cause of that pain often starts somewhere else in the body.

I learned that from this week's guest, Dr. JJ Thomas, who is my physical therapist and good friend. She was my patient first, and now we are each other's patients. She has practiced physical therapy for more than 25 years and has worked with the Philadelphia 76ers, the Philadelphia Eagles, and athletes from the UFC and US Olympic programs.

What you'll learn in this episode:

Why a chronic tendon injury can come right back, even after eccentric loading or PRP
Whether a frozen shoulder in menopause is a hormone problem, and one of the first movements Dr. Thomas checks
Why she works lying on her stomach, and the 10-minute band routine she wrote for an eight-hour desk day
Why sitting up taller won't fix your posture, and what poor posture tells her about your body
Why she gives patients shoulder blade exercises for their pelvic floor
How much a standard squat does for your posterior chain, and the position she wants you in more often
Why she believes “overuse” injuries are often underuse injuries, and how that changes the way she treats shin splints
Why needling a clinician's quad and adductors normalized his neck rotation
What her blood work showed after years of hard training, and the nutrition change she calls her “game changer”

Is It Too Late to Build Muscle in Menopause? No. Here's What the Studies Show Oct 01, 2026

Show notes

Will I get too bulky?" No. "Is it too late?" Also no. Here's the context: during the menopause transition, women lose lean mass, gain fat, and their muscle becomes harder to build — the same workout and the same protein meal produce less than they did at 30. For years the only conversation has been hormone therapy, yes or no, as if that were the fix. In Part 2 of her menopause series, Dr. Gabrielle Lyon looks at what the evidence actually says builds muscle back.

In this episode:

-Postmenopausal women can build muscle and strength at any age (Frontiers in Endocrinology)

- Up to 8 lbs of skeletal muscle in 12 weeks (J Nutr Health Aging RCT)

- Anabolic resistance: why the same workout and the same meal produce less after menopause

- "I was wrong": hormone therapy vs. lifting, and the conversations with Dr. Donald Layman

- HRT alone and lean mass: a 0.06 kg difference across 12 trials

- Estradiol plus training: bigger quad and fat-free mass gains, maintained at 12 months

- Lift first — the practical translation while the HRT evidence evolves

- Why protein matters more after menopause, and why 60 g spread thin isn't enough

- The RDA (0.8 g/kg) isn't enough to protect bone; ESCEO's 1–1.2 g/kg floor

- Doubling protein to 1.6 g/kg: more fat lost, more lean mass kept

- The 6-step Forever Strong menopause protocol

10:21 Why protein matters more after menopause (and why 60 g isn't enough)

11:16 The RDA won't protect your bones: the 1–1.2 g/kg floor

12:16 Doubling protein: more fat lost, more lean mass kept

13:22 The Forever Strong protocol, step 1: train 2–3 days a week

14:15 Steps 2–3: 30–50 g protein at first and last meal, impact and loading

How to Prepare Your Body for Surgery: Protein, Prehab and the 5 Days That Change Your Recovery | Dr. Rebecca Knackstedt Sep 29, 2026

Show notes

Most patients are told one thing before surgery: stop all supplements. Duke surgeon Dr. Rebecca Knackstedt says that blanket advice can do harm, and that what you do in the days before surgery changes how you heal.

Dr. Knackstedt is a plastic and reconstructive microsurgeon on faculty at Duke, an MD-PhD researcher and a certified functional medicine provider whose research focuses on surgical prehabilitation: preparing the body, mind, and home before surgery, the way we already do with rehab.

In today’s episode, we discuss:

• What prehab looks like for any operation

• The labs she checks

• Which supplements to keep and which to stop (omega-3s do not increase bleeding)

• Hormones after breast cancer

• Why mammograms still beat thermography

• What chemo does to metabolism

• The questions to ask your oncologist before a treatment decision

• How much protein to eat (no standard exists, and the average woman gets 60 to 70 grams a day, well short of the 100-gram floor)

• Why surgery is catabolic and muscle is your reserve

• Carbohydrate loading before the fasting cutoff and why it can reduce pain

• The five-day window that lowered complications and even mortality in head and neck cancer patients

• Why early walking replaced routine bed rest

Menopause Is a Muscle Problem, Not Just a Hormone Problem Sep 24, 2026

Show notes

Menopause is changing your body, but the part nobody talks about isn't hot flashes. It's muscle. Women lose lean mass fastest in perimenopause, the loss probably starts closer to 35, and no pill, patch or injection fixes it.

In this solocast, Dr. Gabrielle Lyon explains what estrogen, testosterone and FSH actually do to your metabolism, why a 50-year-old body can still build muscle, and the training and protein protocol to start now.

ED Predicts Heart Attacks Better Than Chest Pain: The 2 Tests to Ask For | Dr. Tobias Kohler Sep 22, 2026

Show notes

Your testosterone number matters at every age, but most men never learn what theirs should be. Mayo Clinic urologist Dr. Tobias Kohler explains why ~500 is the target, why 1,000 is already running hot, what 2,000+ does to the heart, and why a randomized trial found lifting without steroids beat steroids without lifting. Plus: the blood test that catches heart risk your cholesterol panel misses.

Dr. Kohler returns for his second appearance (his first, on erections, testosterone and muscle mass, is one of the most-watched episodes in the show's history). This time: why men's longevity is roughly 50 years behind women's; the Princeton IV consensus he co-chaired, which treats ED as one of the strongest predictors of a future heart attack and points young men toward a coronary calcium scan; the 0–12 ceramide blood test that changes with your behavior; how to get a testosterone baseline that actually means something; what redlining to 2,000–3,000 does to the heart, the set point and the skin; Peyronie's disease, Viagra vs. Cialis, the pills-to-implant ladder, sexual rehab after prostate surgery, and a patient who got stronger with zero testosterone.

About Dr. Tobias Kohler

Tobias S. Kohler, MD, MPH, is Professor of Urology at Mayo Clinic, a fellowship-trained andrologist with 25+ years of clinical and surgical experience and 250+ peer-reviewed publications. He co-chaired the Princeton IV Consensus Guidelines on ED and cardiovascular disease, co-founded the EROS penile implant registry, and co-edited Contemporary Treatment of Erectile Dysfunction (2nd ed.).

The Truth About Testosterone in Women Sep 17, 2026

Show notes

You say "steroids" and picture a baseball scandal, a jacked guy, a bad spray tan. But cortisol is a steroid. Estrogen is a steroid. The cream you put on poison ivy is a steroid. The word covering all of them is also covering testosterone therapy for women, and that collision is quietly costing women muscle and bone they don't have to lose.

In this solo episode, prompted by a magazine interview on steroid use in women, Dr. Gabrielle Lyon breaks down what these molecules actually are, what they do inside a cell, and why the line between medicine and misuse has nothing to do with the word "steroid."

Fathers Lose Testosterone When They Raise Their Kids | Aldrich Chan, Psy.D. Sep 15, 2026

Show notes

Most people assume becoming a parent is an emotional change, but a measurable part of it is hormonal, and it happens in fathers too. I sat down with Aldrich Chan, Psy.D., to talk about what changes in the brain, why the split we draw between mind and body does not hold up, and what decides whether stress reads as manageable or overwhelming when the hormones are identical either way.
