Why Protein Needs Are Higher Than You Think: Lessons from Two Leading Scientists (Dr. Carlene Starck & Dr. Arny Ferrando Recaps)
Beat BLOAT & unlock better protein absorption and digestion with MassZymes by BiOptimizers. NOW GET 15% off your order with the code VANESSA at bioptimizers.com/vanessa In this special solocast, Vanessa recaps the top highlights from two powerhouse researchers in protein metabolism: Dr. Carlene Starck and Dr. Arny Ferrando. If your goal is fat loss, muscle preservation, and body recomposition—especially in peri and post-menopause—this episode is packed with evidence-based strategies you can start applying today. 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. 🔬 From Dr. Carlene Starck: • Why current essential amino acid (EAA) requirements are likely underestimated. • The role of oxidation and gut turnover in daily amino acid losses. • Why the optimal EAA:non-EAA ratio is ~41–42%—and what that means for protein quality. • Plant vs. animal proteins for body composition and calorie efficiency. • Updated protein targets for women in perimenopause and menopause. • Creatine, collagen, and key micronutrients for women’s metabolic health. 💪 From Dr. Arny Ferrando: • Protein-Sparing Modified Fast (PSMF) vs. water fasting for fat loss and muscle preservation. • GLP-1 agonists: the hidden risks to muscle mass and how to protect yourself. • Collagen for surgery recovery, connective tissue health, and repair. • The two levers of anabolism: amino acid signal + blood flow delivery. • How EAAs timed with movement can overcome anabolic resistance. • Practical programming for peri/post-menopausal women: resistance training, vertical loading, and activity as medicine. • Red light therapy & blood flow restriction: when tools can help support blood flow. ✨ Key Takeaway: Protecting muscle and improving body composition comes down to two things: Quality protein and EAAs to maximize the anabolic signal. Movement and blood flow to deliver those amino acids to muscle. When you combine these, you unlock the blueprint to preserve lean mass, lose fat, and age strong.

Get 30% off your subscription, plus a free gift with your second shipment at Ketone.com/vanessa. In this highly requested follow-up, Dr. Arny Ferrando returns to the Optimal Protein Podcast to go even deeper into the science of preserving muscle and optimizing body composition. Dr. Ferrando is one of the world’s leading researchers in muscle protein metabolism, with over 35 years of groundbreaking work on essential amino acids, anabolic resistance, and nutrition-exercise interactions. We kick things off with his perspective on Protein-Sparing Modified Fasts (PSMF) versus water fasting, and the implications each has for fat loss and lean mass preservation. Dr. Ferrando also shares his positive take on collagen supplementation, including how it can support connective tissue health, and weighs in on the potential risks of GLP-1 medications to muscle tissue during rapid weight loss. NEW! Support your strength and muscle goals with PUORI Creatine+ — a clean, effective creatine monohydrate supplement enhanced with magnesium and vitamin B12. Get 20% off at puori.com/VANESSA We kick things off with his perspective on Protein-Sparing Modified Fasts (PSMF) versus water fasting, and the implications each has for fat loss and lean mass preservation. Dr. Ferrando also shares his positive take on collagen supplementation, including how it can support connective tissue health, and weighs in on the potential risks of GLP-1 medications to muscle tissue during rapid weight loss. The heart of this episode dives into anabolic resistance during menopause. Dr. Ferrando explains why it may not just be about hormones, but also about impaired nutrient delivery to muscle. He describes amino acids as the “signal” and blood flow as the “delivery truck”—a powerful analogy that reveals why exercise is so critical to overcoming anabolic resistance. We explore practical strategies for women to preserve muscle and improve body composition during midlife and beyond, including: Why blood flow and nutrient delivery may matter as much as hormones. How red light therapy and blood flow restriction training (BFR) could enhance amino acid delivery and muscle responsiveness. His recommendations for EAA dosing, timing, and frequency in peri- and postmenopausal women. The role of microvascular health and endothelial function in muscle retention. Why free-form EAAs are more efficient than intact protein under calorie restriction. This conversation is packed with actionable science and myth-busting insights that will help you understand how to protect your muscle, burn fat, and stay strong at every stage of life.
