• BRAND NEW Study on How Much Protein During Fat Loss to Maintain Muscle: Dr. Martin Refalo

  Timeline: Get 10% off Mitopure, clinically proven to boost mitophagy.  Go to timeline.com/vanessa. In this episode of The Optimal Protein Podcast, I sit down with Dr. Martin Refalo to discuss his brand-new study: Effect of Dietary Protein on Fat-Free Mass in Energy-Restricted, Resistance-Trained Individuals: An Updated Systematic Review With Meta-Regression (Refalo, Trexler, & Helms, 2025). This research provides an updated analysis of how dietary protein intake impacts muscle retention during fat loss in resistance-trained individuals. If you’ve ever wondered how much protein you really need while cutting to preserve muscle mass, this episode is for you! What We Cover in This Episode: -What does the latest meta-regression reveal about protein intake and fat-free mass during caloric restriction? -How does protein intake affect lean muscle retention across different levels of caloric deficits? -Does going above the commonly recommended 1.6 g/kg improve muscle retention? -What are the potential upper limits of protein intake for maximizing muscle preservation? -How does resistance training influence protein requirements during a diet? -Differences between male and female subjects—should women aim for different targets? -Practical recommendations for athletes, bodybuilders, and general fitness enthusiasts looking to optimize fat loss while keeping their muscle gains. Dr. Refalo, along with co-authors Dr. Eric Trexler and Dr. Eric Helms, has compiled the most up-to-date evidence to help you make data-driven decisions about your diet and training.

• TWO NEW (March 2025) Studies: Omega-3, Vit D & Exercise Reverses Biological Age + New Systematic Review on Keto/Low Carb for Fat Loss

  Use the code KETOGIRL for 20% off your order of Spirulina Here In this episode of The Optimal Protein Podcast, we dive into two fascinating new studies that explore how diet, supplementation, and exercise impact biological aging and body composition. 📌 Study 1: How omega-3s, vitamin D, and exercise work together to slow down biological aging—and why the combination may be more powerful than any of these interventions alone. 📌 Study 2: A systematic review and meta-analysis on ketogenic and low-carb diets, breaking down their impact on body weight, BMI, and fat mass. Key Takeaways from This Episode: ✅ A new study shows how combining omega-3s with vitamin D and exercise may have a major impact on biological aging. ✅ A deeper look at why omega-3s are crucial for longevity and how I personally get mine from marine algae, like ENERGYbits®, a plant-based source of ALA, EPA, and DHA. ✅ What the latest ketogenic diet research tells us about fat loss and body composition—and what it didn’t show. ✅ Why stacking multiple lifestyle interventions together may be the key to long-term health and longevity. 🎧 Tune in now to hear all the details and practical takeaways from these two exciting new studies!

• New Study on Women, Muscle Mass & Strength Gains, and Micronutrient Deficiencies

  Use the code KETOGIRL for 20% off your order of Spirulina Here A new study reveals a surprising truth: muscle mass and strength don’t always improve the same way. While protein intake plays a key role in muscle growth, micronutrient deficiencies—especially in Vitamin D, B12, Magnesium, and Iron—can significantly impact strength gains. In this episode, I break down a new randomized clinical trial that studied older women at risk of sarcopenia and analyzed how different types of resistance training and dietary intake affected muscle function, body composition, and overall strength. What You’ll Learn in This Episode: • The difference between muscle mass gains and strength gains and why they require different approaches • Which micronutrients are essential for building strength and muscle function • Why protein intake alone isn’t enough and what you need to focus on instead • How to assess your own micronutrient levels for better performance and recovery as well as the top micronutrient rich foods to prioritize with a foods-first approach • Practical diet, supplement and training tips to maximize both muscle and strength If you want to build strength and muscle efficiently, or if you are health-conscious and looking to optimize your diet and training, this episode is packed with actionable insights. Mentioned in this episode: Nutritional intake as a determinant of high-speed resistance and multicomponent training efficacy on strength in older women at risk of sarcopenia.
