Timeline: Get 10% off Mitopure, clinically proven to boost mitophagy. Go to timeline.com/vanessa. What if the key to a leaner body, a clearer mind, and total food freedom isn’t willpower… but your gut bacteria? In this powerful episode of The Optimal Protein Podcast, I’m joined by world-renowned physician, author, and gut health pioneer Dr. Steven Gundry to dive into the bold insights from his new book, The Gut-Brain Paradox. Dr. Gundry reveals how an imbalanced microbiome doesn’t just affect digestion — it can hijack your cravings, dull your focus, and even impact your mood, behavior, and metabolism. But here’s the good news: these changes are reversible. And it starts with a targeted reset. We explore how gut health connects to everything from depression and addiction to Alzheimer’s and disordered eating — and how a protein-optimized, keto-friendly lifestyle can help restore your gut-brain axis for long-term health, vitality, and leanness.

High Protein, Zero Fat Gain: A Shocking Study on Resistance Trained Women
IQBAR is offering our special podcast listeners 20% OFF all IQBAR products, plus get FREE shipping. To get your 20% off, text VANESSA to 64000. That’s VANESSA to sixty-four thousand. Message and data rates may apply. See terms for details. In this solo science breakdown, we explore one of the most impactful studies on protein intake in women who resistance train. This 8-week randomized controlled trial looked at how eating either high or low protein influenced muscle gain, fat gain, and strength in women training for physique competition. Despite eating more calories, the high-protein group experienced a shocking amount of muscle gain and fat loss. The findings challenge conventional bulking and cutting wisdom and highlight the power of protein for female body recomposition. 📌 Topics Covered: • Overview of the study design: 8 weeks, trained women, controlled protein intake • Why the RDA for protein is insufficient for active women • How high protein builds muscle without fat gain—even in a surplus • The metabolic advantages of high protein (TEF, nutrient partitioning, satiety) • Practical recommendations for women lifting weights • Limitations of the study and why it still matters • Your action plan for applying the research 📖 Reference: Campbell, B. I., et al. (2018). Effects of high versus low protein intake on body composition and maximal strength in aspiring female physique athletes engaging in an 8-week resistance training program. International Journal of Sport Nutrition and Exercise Metabolism, 28(6), 560-565. 🧠 Quote of the Episode: “You can eat more—especially protein—and still stay lean, or even lean out."

Turn Fat Into Muscle?! What 2 New Studies Say About Ketones and Vitamin D
IQBAR is offering our special podcast listeners 20% OFF all IQBAR products, plus get FREE shipping. To get your 20% off, text VANESSA to 64000. That’s VANESSA to sixty-four thousand. Message and data rates may apply. See terms for details. In this episode of The Optimal Protein Podcast, I take a deep dive into two exciting new studies that could reshape how we think about fat loss and body composition. The first study investigates how a medically supervised ketogenic diet not only promotes fat loss but reverses biological aging by more than 6 years. And it’s not just the calorie restriction—the study found that elevated ketones, especially beta-hydroxybutyrate, played a key role in reducing epigenetic age and promoting longevity pathways. The second study examines high-dose vitamin D supplementation and how it may direct surplus calories away from fat storage and toward muscle growth—via mechanisms involving myostatin and leptin signaling. While preclinical, the findings open up new conversations around vitamin D as a muscle-preserving, fat-loss–enhancing tool. If you’re focused on losing fat, preserving muscle, and optimizing metabolic health, this episode is packed with cutting-edge insights.

The Truth About Cycle Syncing, Hormones, and Women’s Performance with Dr. Victoria Felkar
Timeline: Get 10% off Mitopure, clinically proven to boost mitophagy. Go to timeline.com/vanessa. In this episode of the Optimal Protein Podcast, I’m joined by Dr. Victoria Felkar, a leading expert in women’s health, endocrinology, and performance. Victoria’s work challenges common myths and misconceptions surrounding women’s health — from hormone fluctuations to muscle growth and strength training. In this episode, we discuss: ✅ Why the belief that women and men are vastly different in muscle growth and strength isn’t as clear-cut as you might think ✅ Misconceptions about cycle syncing and whether tailoring training to the menstrual cycle is backed by solid science ✅ Why overly simplified messages about hormones and female health can do more harm than good ✅ The dangers of focusing solely on estradiol in peri- and post-menopause and why this narrow focus is bad science ✅ Why isolating health into distinct processes — like sleep, nutrition, or hormones — overlooks the interconnectedness between these factors Victoria’s insights will empower you to better understand the complexities of female physiology and take a science-backed approach to improving your health, performance, and body composition. Episode Highlights: 🧠 Common misconceptions about women’s health and performance — and what the science really says 💪 Are women and men really that different when it comes to building strength and muscle? 🔍 Why oversimplifying menstrual cycle training strategies can mislead women 🔥 The surprising truth about hormonal influences in peri- and post-menopause 🌐 Why sleep, nutrition, and hormones shouldn’t be treated in isolation — and how interconnected these systems really are Get 20% off on the Tone LUX Crystal Red Light Therapy Mask Ketogenicgirl.com with the code VANESSA Join the Community!
