In this episode, Vanessa Spina interviews Dr. Hans H. Stein, Professor of Animal Sciences at the University of Illinois Urbana-Champaign, about protein quality, amino acid digestibility, and why "grams of protein" on a label do not always reflect what the body can actually use. The PSMF Library is officially live 🎉 👉 Check it out here + get 20% off with code VANESSA . Stein explains why we do not technically need protein — we need digestible indispensable amino acids — and why this matters for muscle protein synthesis, aging, pregnancy, lactation, fat loss, and body recomposition. They discuss animal versus plant proteins, DIAAS and PDCAAS scoring, why plant-based burgers may not be biologically equivalent to animal-based burgers, how food processing can improve or damage protein quality, and why protein quality becomes even more important during calorie restriction. This conversation will change how you think about protein labels, protein targets, and the amino acids needed to preserve lean mass while losing fat.

In this episode of the Optimal Protein Podcast, Vanessa is joined by Dr. Brian Mowll for a deep dive into protein-sparing modified fasting, or PSMF, as part of the Friday Protein-Sparing Modified Fasting Series. Check out the Protein-Sparing Modified Fasting Library at ketogenicgirl.com and use code VANESSA for 20% off. Dr. Mowll explains the origins of PSMF, how it was first developed in clinical settings to help preserve lean body mass, and why it later became a powerful tool for obesity, metabolic health, and fat loss. Vanessa and Dr. Mowll explore how PSMF compares to water fasting and very low-calorie diets, especially when the goal is fat loss while protecting muscle. They discuss how strategic energy restriction, optimized protein intake, low carbohydrate intake, and low dietary fat can help the body access stored body fat while maintaining lean mass, metabolic rate, satiety, and ketone production. Dr. Mowll also explains how PSMF may support insulin sensitivity, blood sugar regulation, metabolic flexibility, and long-term weight maintenance when followed by a smart transition plan. This episode also covers practical implementation, including what to eat on PSMF days, ideal protein targets, how low to take carbs and fats, hunger signals, why some people feel energized, and how to transition out of PSMF to reduce the risk of rebound weight gain.

In this fascinating episode of the Optimal Protein Podcast, Vanessa Spina is joined by Dr. Fernando Naclerio, Professor in Strength Training and Sports Nutrition at the University of Greenwich and Centre Lead for the Centre for Exercise Activity and Rehabilitation. Vanessa and Dr. Naclerio dive into a brand new meta-analysis comparing higher-carb and lower-carb diets when calories and protein are matched. While both approaches improved body composition, the low-carb diets produced greater reductions in fat mass, fasting glucose, fasting insulin, and triglycerides, along with increases in HDL. This conversation explores why not all weight loss is fat loss — and why consuming too many carbohydrates during a calorie deficit may, in certain conditions, shift the body toward burning more lean mass instead of body fat. They also discuss how to structure protein, carbohydrates, and fats for better body composition, why carbohydrate tolerance depends on activity level, the importance of resistance training, keto adaptation, meal timing, fasting, protein distribution, and why protecting muscle should be the priority during fat loss.
