In today's Friday solo recap on the Optimal Protein Podcast, I break down the most important takeaways from my recent conversation with Dr. Gabrielle Lyon — and why this episode has major implications for fat loss, metabolic health, and women's body composition.

One of the biggest themes of our discussion was that muscle is not just about aesthetics. It's a metabolic organ, and preserving it is foundational for long-term health — especially for women as we age.

I also connect this conversation to the new protein recommendations reflected in the 2025–2030 Dietary Guidelines, which now align far more closely with modern protein science. For the first time, official guidance is moving beyond minimums designed to prevent deficiency and toward intakes that actually support muscle preservation, metabolic health, and satiety. We also cover a brand new study on weight loss drugs and fat regain.

In this recap, I cover:

• Why we don't have an "overfat" problem — we have an undermuscled problem

• Why midlife fat gain is not inevitable (and not just about hormones)

• How carb tolerance and activity level influence fat storage

• Why excess carbohydrates quietly work against fat loss when muscle demand is low

• The overlooked role of muscle blood flow and intramuscular fat

• Why under-eating accelerates muscle loss in women

• How weight loss drugs can worsen fat regain if muscle isn't protected

• Why strength training is non-negotiable — but must be appropriate

• Why protein isn't just calories, but a signal for muscle and metabolism

If your goals include fat loss, body recomposition, and aging strong, this episode will help you rethink how protein, carbs, and muscle fit together — and why preserving muscle is the real long-term strategy.

In this episode of the Optimal Protein Podcast, I'm joined by Dr. Gabrielle Lyon to break down the muscle-centered strategy every woman needs for fat loss, metabolic health, and long-term strength.

We unpack why muscle — not hormones alone — is the key driver of body composition, why midlife fat gain is not inevitable, and how protein intake, movement, and muscle blood flow shape metabolism as women age. Dr. Lyon also explains her much-discussed concept of carb tolerance, how to "earn your carbs," and why excess carbohydrates can quietly work against fat loss when muscle demand is low.

In this episode, you'll learn:

• Why most health goals fail by February

In this episode of the Optimal Protein Podcast, Vanessa is joined by Cynthia Thurlow, nurse practitioner, bestselling author, and women's health expert, for a deep dive into why fat loss and muscle maintenance become more challenging during perimenopause and menopause.

Cynthia explains how hormonal shifts drive anabolic resistance, reduce blood flow and nutrient delivery to muscle, and accelerate changes in body composition. We discuss how to adapt intermittent fasting for female physiology, why over-fasting can backfire in midlife, and the critical role of protein intake in preserving lean mass.

The conversation also explores key insights from Cynthia's upcoming book, The Menopause Gut, including how gut health, inflammation, and hormonal balance are deeply connected—and why optimizing the microbiome can improve metabolic health, body composition, and overall vitality in midlife.

Why do so many people lose weight — only to regain it later?

In this episode of The Optimal Protein Podcast, Vanessa Spina sits down with Dr. Holly Wyatt, physician, endocrinologist, and longtime researcher with the National Weight Control Registry (NWCR) — the world's largest and longest-running study of people who have lost weight and kept it off.

Building on the audience-favorite episode with Dr. James Hill, this conversation focuses on what the data from over 10,000 successful maintainers actually shows — and why staying in fat-loss mode forever is one of the biggest reasons diets fail.
