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.

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.  Get 20% off the TONE LUX red light collection or the 2nd Generation Tone Device HERE  with the code VANESSA Follow @ketogenicgirl for updates on the latest studies and strategies to optimize protein intake and metabolic health.  🔍 What You’ll Learn in This Episode: • How the very-low-calorie ketogenic diet (VLCKD) reversed biological aging in adults with obesity • The role of ketonemia (beta-hydroxybutyrate) in slowing cellular aging • Ketones as signaling molecules: antioxidant effects, insulin sensitivity, autophagy, and more • The potential for endogenous ketones to promote longevity • How high-dose vitamin D may reprogram calorie allocation—favoring muscle over fat • The roles of myostatin suppression and leptin signaling in body recomposition • Why optimizing vitamin D status could matter for muscle preservation and fat loss • What this research means for your own diet, supplementation, and metabolic strategy 📚 Studies Referenced: 1.

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!

Jump straight to the studies breakdown: 14:36  In this episode of The Optimal Protein Podcast, we dive deep into two groundbreaking studies that reveal powerful insights into appetite regulation, fat loss, and muscle maintenance. You’ll learn how weight loss impacts hunger hormones — and how a strategic focus on protein intake can help you stay fuller for longer, improve metabolic health, and preserve lean muscle mass. Key Topics Covered: 🔎 Study 1: "Fasting appetite-related gut hormone responses after weight loss induced by calorie restriction, exercise, or both in people with overweight or obesity: a meta‐analysis." • Why researchers explored the hormonal responses to different weight loss strategies • How calorie restriction, exercise, or a combination of both affects hunger hormones like ghrelin, PYY, GLP-1, and CCK • Why individuals who lose more fat-free mass (FFM) may experience greater hunger spikes — and how resistance training and protein can help mitigate this effect 🍳 Protein and Satiety Hormone Research • How high-protein diets increase key satiety hormones like PYY, GLP-1, and CCK • The exciting discovery of LEAP2, a hormone that suppresses ghrelin and helps reduce appetite — especially in ketogenic and high-protein diets 💪 Study 2: "Exploring Opportunities to Better Characterize the Effects of Dietary Protein on Health Across the Lifespan" • How much protein older adults require per meal to stimulate muscle protein synthesis • How to balance protein distribution across meals for superior results in muscle maintenance and appetite control • Which protein source proved particularly effective for boosting MPS, especially when paired with resistance training • Insights on how increased protein intake improves insulin sensitivity, glucose control, and enhances satiety hormones to help manage long-term appetite 🎧 Tune in now for practical insights you can apply to your nutrition and fitness strategy today! 🎧 Tune in now for powerful insights you can apply to your diet and lifestyle!  Get 20% off the TONE LUX red light collection or the 2nd Generation Tone Device HERE  with the code VANESSA Follow @ketogenicgirl for updates on the latest studies and strategies to optimize protein intake and metabolic health.  Follow @optimalproteinpodcast on Instagram to see visuals and posts mentioned on this podcast.
