Creatine, Fat Cells & Body Recomposition: New Science You Haven't Heard — Dr. Scott Forbes

In this episode of The Optimal Protein Podcast, Vanessa Spina welcomes back leading muscle metabolism researcher Dr. Arny Ferrando for a deep dive into protein, muscle, and women's physiology across the menopause transition. Timeline Mitopure Gummies — The #1 Urolithin A supplement for energy and healthy aging, now in delicious strawberry gummies. Get 20% off at timeline.com/vanessa They explore why perimenopause represents a critical turning point for whole-body protein balance, how muscle loss accelerates during midlife, and why protein quality, dosing, and movement become essential for preserving lean mass and metabolic health. Dr. Ferrando also shares insights from forthcoming research comparing animal-based and plant-based proteins, and explains why muscle is the body's primary survival tissue during stress and aging. This conversation delivers clear, evidence-based strategies for improving body composition, fat loss, and long-term health in women. Topics include: Why menopause changes protein utilization and muscle retention Perimenopause as a muscle-critical intervention window Protein intake vs. protein optimization Essential amino acids (EAAs): when supplementation is useful Muscle loss, fat gain, and metabolic slowdown in midlife Why muscle preservation matters more than scale weight The role of circulation, blood flow, and resistance training Fat loss without muscle loss: what the science shows GLP-1 weight loss drugs and concerns around lean mass loss Emerging research on beef-based vs. plant-based proteins for women Dr. Arny Ferrando is a world-leading researcher in human protein metabolism, muscle physiology, and aging. His work has helped define how amino acids, protein intake, and exercise influence muscle preservation, recovery, and metabolic health across the lifespan. 👉 Subscribe, rate, and review the Optimal Protein Podcast to support the show and help bring you more evidence-based conversations on fat loss, protein, and muscle-centric nutrition.

Most people think creatine only affects muscle strength and performance. But what if creatine also plays a role inside fat cells themselves—and could subtly influence fat loss and body recomposition? In this episode of the Optimal Protein Podcast, Vanessa Spina I recaps the key takeaways from the interview with Dr. Scott Forbes, focusing on fat loss, body recomposition, muscle preservation, protein intake, creatine supplementation, sleep, and aging. This episode breaks down brand new research on how different training modalities, recovery, and evidence-based supplements influence fat loss and body composition—and why scale weight alone is a poor marker of fat loss success. 🧠 IQBAR – Try the Ultimate Sampler Pack: IQBARs, IQMIX, and IQJOE!

Timeline Mitopure Gummies — The #1 Urolithin A supplement for energy and healthy aging, now in delicious strawberry gummies. Get 20% off at timeline.com/vanessa Most fat-loss advice focuses on the scale — but what if that's the wrong metric entirely? In this episode, Vanessa Spina is joined by Dr. Scott Forbes, exercise physiologist and professor at Brandon University, whose research challenges many of the assumptions behind traditional weight-loss approaches. Dr. Forbes has authored and co-authored numerous randomized controlled trials and large meta-analyses examining how training style, protein intake, creatine supplementation, sleep, and aging influence fat loss, muscle retention, and metabolic health. Rather than chasing weight loss, this conversation explores what happens when the goal shifts to body recomposition — losing fat while preserving or building muscle — and why that distinction changes everything. In this episode, we explore: Why weight loss and fat loss are not the same thing The surprising differences between cardio, resistance training, and combined approaches Why some people lose weight but stall metabolically How protein and creatine fit into a muscle-centric fat-loss strategy Why fat loss becomes harder with age — and what still works A largely overlooked factor that influences where fat is stored If you've ever done "everything right" and still felt stuck, this episode offers a science-backed reframe that may completely change how you approach fat loss. 👉 Subscribe, rate, and review the Optimal Protein Podcast to support the show and help bring you more evidence-based conversations on fat loss, protein, and muscle-centric nutrition.

Skip to the start of the recap: 13:41 In today's Friday solo episode of The Optimal Protein Podcast, Vanessa breaks down the science of leptin — the hormone that determines whether your body will burn fat or protect it. Leptin isn't just about appetite. It's a metabolic permission signal, and when leptin signaling is disrupted, fat loss can stall even in a calorie deficit. 🧠 IQBAR – Try the Ultimate Sampler Pack: IQBARs, IQMIX, and IQJOE! Text VANESSA to 64000 for a 20% off discount code Vanessa explains how sleep, circadian rhythm, and light exposure affect leptin, why dieting can feel harder than it should, and walks you through a practical 7-Day Leptin Reset Protocol designed to reduce hunger, improve satiety, and make fat loss feel easier.

Get 20% off at timeline.com/vanessa In this episode, I'm joined by Dr. Catherine Clinton to explore how circadian biology, light exposure, and cellular electrical charge regulate metabolism, hormones, and fat loss — often beyond calories alone. We discuss how morning light impacts leptin signaling, insulin sensitivity, cortisol, and melatonin, why modern indoor living disrupts metabolic health, and how maintaining a strong negative cellular charge is critical for mitochondrial function. We also cover red and infrared light therapy, optimal timing, metabolic benefits, and key considerations during pregnancy — plus how to integrate protein intake, calories in vs. calories out, and resistance training with circadian alignment for sustainable fat loss.

Dr. Barringer has led cutting-edge research on protein intake, recovery, and resilience under extreme physical and psychological stress, working with tactical athletes including Army Rangers, Navy SEALs, and West Point cadets. This conversation goes far beyond the military. Dr. Barringer breaks down how women and everyday high performers can apply the same evidence-based strategies to lose fat without losing muscle, recover more effectively, and avoid the biggest pitfalls of aggressive dieting. Together, Vanessa and Dr. Barringer cut through fear-based nutrition messaging and explore what human research actually shows about protein intake, recovery, seed oils, supplements, and collagen.

Skip to the start of the episode: 11:52 In today's Friday solo recap on the Optimal Protein Podcast, I break down the most important takeaways from my recent conversation with Dr. Gabrielle Lyon — and why this episode has major implications for fat loss, metabolic health, and women's body composition. 🧠 IQBAR – Try the Ultimate Sampler Pack: IQBARs, IQMIX, and IQJOE! Text VANESSA to 64000 for a 20% off discount code One of the biggest themes of our discussion was that muscle is not just about aesthetics. It's a metabolic organ, and preserving it is foundational for long-term health — especially for women as we age. I also connect this conversation to the new protein recommendations reflected in the 2025–2030 Dietary Guidelines, which now align far more closely with modern protein science. For the first time, official guidance is moving beyond minimums designed to prevent deficiency and toward intakes that actually support muscle preservation, metabolic health, and satiety. We also cover a brand new study on weight loss drugs and fat regain. In this recap, I cover: Why we don't have an "overfat" problem — we have an undermuscled problem Why midlife fat gain is not inevitable (and not just about hormones) How carb tolerance and activity level influence fat storage Why excess carbohydrates quietly work against fat loss when muscle demand is low The overlooked role of muscle blood flow and intramuscular fat Why under-eating accelerates muscle loss in women How weight loss drugs can worsen fat regain if muscle isn't protected Why strength training is non-negotiable — but must be appropriate Why protein isn't just calories, but a signal for muscle and metabolism If your goals include fat loss, body recomposition, and aging strong, this episode will help you rethink how protein, carbs, and muscle fit together — and why preserving muscle is the real long-term strategy.
