Optimal Protein Podcast with Vanessa Spina

Dr. Antonella Schwarz returns to the Optimal Protein Podcast to discuss her latest study restuls and why building muscle—not simply losing weight—is one of the most powerful things we can do for longevity, metabolic health, and body composition. The PSMF Library is officially live 🎉 👉 Check it out here + get 20% off with code VANESSA In this episode, Vanessa and Dr. Schwarz dive into why the scale can be misleading, why fat loss is not the same as weight loss, and how resistance training helps preserve lean mass, support metabolism, and improve long-term health and independence. They also explore Dr. Schwarz's latest research on high-protein intake and muscle adaptation, including why consistently hitting higher protein targets may support greater muscle size and strength gains—especially for active individuals and women as they age. The conversation also covers resistance training during perimenopause, menopause, and pregnancy, including how lifting weights may support mood, confidence, bone density, body composition, and overall resilience. Dr. Schwarz also shares how she adapted her own training and nutrition while exercising throughout pregnancy. In this episode: Why the scale may be misleading you about your true body composition The hidden downside of fat loss without resistance training What Dr. Schwarz's newest research revealed about higher protein intake and muscle growth Why strength may be one of the most important predictors of longevity and independence How resistance training may support women through perimenopause, menopause, and pregnancy Why a muscle-first approach could completely change the way you think about fat loss and aging The PSMF Library is officially live 🎉 This is the exact structured, high-protein approach Vanessa used for fat loss and body recomposition — without restricting calories every single day.

Why do so many people lose weight at first on keto or carnivore… only to eventually stall or even gain weight? In this Friday recap episode, Vanessa breaks down the biggest takeaways from her interview with Craig Emmerich, co-author of The Art of Metabolic Health. She explains why ketosis alone does not guarantee body fat loss, why high dietary fat can prevent the body from tapping into stored fat, and how protein-prioritized keto may be a more effective approach for fat loss and body recomposition. Check out the Protein-Sparing Modified Fasting Library at ketogenicgirl.com and use code VANESSA for 20% off. Vanessa also dives into fuel partitioning, the Randall cycle, personal fat threshold, and why so many people get stuck in "diet islands" after using keto, carnivore, fasting, or low-carb diets to lose weight. She shares her personal experience gaining weight on traditional high-fat keto, then later losing 14 pounds of body fat using alternating protein-sparing modified fasting days and maintenance days. This episode is all about using structure, protein, and metabolic strategy to burn body fat while preserving lean mass. In This Episode Why high-fat keto can stall fat loss The difference between burning dietary fat and stored body fat Why ketosis does not automatically mean fat loss How fuel partitioning affects body composition Why protein is the anchor for recomposition The dieting trap of losing muscle and regaining fat How protein-sparing modified fasting protects lean mass Vanessa's approach: alternating PSMF days with maintenance days Why personal fat threshold matters for metabolic health How to avoid getting stuck in keto, carnivore, or fasting "diet islands" Why body composition matters more than scale weight Resources Mentioned Craig & Maria Emmerich The Art of Metabolic Health IQBAR – Try the Ultimate Sampler Pack: IQBARs, IQMIX, and IQJOE!

Why do so many people lose weight on keto… only to stall—or even gain it back? In this episode, Vanessa sits down with Craig Emmerich to break down one of the biggest misconceptions in fat loss: that simply eating high fat will keep the weight coming off. Together, they unpack why high-fat keto can stall fat loss, how fuel partitioning actually works, and what your body is being driven to burn based on your macronutrient intake. The PSMF Library is officially live 🎉 👉 Check it out here + get 20% off with code VANESSA Craig explains the science behind protein as the primary driver of fat loss, why cutting calories alone can backfire, and how repeated dieting or fasting without enough protein can lower metabolic rate by reducing lean muscle mass. They also dive into protein-sparing modified fasting (PSMF)—what it is, how it works, and how to use it strategically 1–3 days per week to accelerate fat loss while preserving muscle. Vanessa shares her personal experience using PSMF to lose body fat efficiently without feeling deprived. You'll also learn: Why combining high fat and high carbs can block fat burning The Randle Cycle and fuel competition explained simply How to break through fat loss plateaus without cutting calories further Who PSMF is best for—and who should avoid it Why structure matters more than willpower How to transition off strict diets and find a sustainable long-term approach At the end of the episode, Craig shares insights into Maria Emmerich's current weight regain journey, including how she is strategically increasing carbohydrates, strength training, and focusing on rebuilding muscle. If you've ever felt stuck on keto or frustrated by fat loss plateaus, this episode will give you a clear, science-backed strategy to move forward. 📘 Craig & Maria Emmerich's Book The Art of Metabolic Health The PSMF Library is officially live 🎉 This is the exact structured, high-protein approach Vanessa used for fat loss and body recomposition — without restricting calories every single day.

In this episode, Vanessa breaks down one of the most important conversations on the podcast to date — her interview with Dr. Carlene Starck on newly published research suggesting that protein requirements may be significantly higher than current guidelines. 🔗 PSMF LIBRARY (PRE-ORDER) The PSMF Library is officially live for pre-order 🎉 get the LAUNCH discount HERE Vanessa dives into what this new model reveals about how the body actually uses — and loses — amino acids every day, and why many people may be under-eating protein even when they think they're eating "high protein." She explains how overlooked factors like gut losses, amino acid oxidation, and protein turnover may be driving higher true protein needs — and what this means for fat loss, muscle retention, satiety, and metabolic health. This episode also highlights why protein quality matters, why essential amino acids are the real drivers of results, and why some protein sources may be far more effective than others when it comes to body recomposition. If you're trying to lose fat, preserve muscle, or optimize your metabolism — this episode connects the dots between cutting-edge research and practical application. In this episode: Why protein requirements may be higher than current guidelines Hidden amino acid losses (gut, oxidation, turnover) Why "high protein" may still not be enough Essential amino acids vs total protein Why protein quality impacts fat loss outcomes Animal vs plant protein efficiency Protein, satiety & appetite regulation How protein supports muscle retention in fat loss Practical protein targets for body recomposition The PSMF Library is officially live for pre-order 🎉 This is a resource Vanessa created based on what worked so effectively for her for fat loss and body recomposition — using a structured, high-protein approach instead of trying to restrict calories every single day.

In this episode of the Optimal Protein Podcast, Vanessa sits down with sports nutrition scientist Dr. Jose Antonio, one of the world's leading researchers on protein metabolism and body composition. Dr. Antonio is widely known for his groundbreaking protein overfeeding studies, which found that participants consuming extremely high protein diets did not gain body fat — and in some cases actually lost more fat — even while eating more calories. In this conversation, Vanessa and Dr. Antonio explore the fascinating metabolic reasons why protein behaves differently in the body, including its thermic effect, impact on satiety, and role in preserving lean mass during fat loss. They also discuss the newly evolving protein recommendations, how protein interacts with carbohydrates and fats in the diet, and why certain athletes may benefit from lower carbohydrate approaches depending on their sport and metabolic demands. If your goal is fat loss, body recomposition, or maintaining muscle while dieting, this episode offers a deep dive into the science behind why prioritizing protein can be such a powerful strategy. In This Episode • Why protein overfeeding studies showed more calories did not lead to fat gain • The metabolic reasons protein calories behave differently in the body • How high protein intake supports fat loss and lean muscle preservation • The science behind the thermic effect of protein • Why newer protein recommendations are increasing • How protein, carbohydrates, and fats interact to influence body composition • Why certain athletes may benefit from lower carbohydrate strategies Timeline Mitopure Gummies — The #1 Urolithin A supplement for energy and healthy aging, now in delicious strawberry gummies.

In this episode, Vanessa is joined by Dr. Jason Fung, author of The Hunger Code, to unpack the hormonal science behind fat loss — and how fasting may be entering a new era. They start with the three types of hunger and why obesity is not simply about willpower, but disrupted hormonal signaling. We break down insulin's role in fat storage, obesity, and how ultra-processed foods blunt satiety hormones. Vanessa and Dr. Fung also discuss how protein, fiber, and fat affect hunger very differently than refined carbohydrates — and why a calorie is not metabolically neutral. Then they shift to fasting. Dr. Fung shares his current protocols and comments on emerging research supporting Protein-Sparing Modified Fasting (PSMF) as a more practical, muscle-conscious alternative to prolonged water fasting. They cover: • PSMF vs water fasting • Protecting lean mass during fat loss • GLP-1 medications — risks and unintended consequences • Appetite suppression vs true metabolic health • Fat loss considerations for women in peri- and post-menopause This conversation challenges the idea that all fasting approaches are created equal — and reframes modern fat loss through a hormonal lens.

What do elite athletes do differently when it comes to fat loss? In this episode, Vanessa breaks down the most surprising takeaways from her conversation with sports dietitian Emily Mitchell, who has worked with professional teams including UCLA Athletics, the LA Galaxy, the Clippers, and the Buccaneers. While many people think getting lean requires constant dieting, eliminating carbohydrates, and pushing through hunger, elite athletes often take a completely different approach. Vanessa explores six of the most powerful fat loss strategies used by elite performers — including why many athletes don't diet during their competitive season, why protein intake is far higher than most people realize, and how strategic carbohydrate timing can actually support fat loss and performance. 🧠 IQBAR – Try the Ultimate Sampler Pack: IQBARs, IQMIX, and IQJOE!

Fasted training is one of the most persistent fat-loss myths—and in this episode, Dr. Katie Hirsch breaks down what actually matters for women: training quality, muscle preservation, and metabolic health. We unpack why "burning more fat during a workout" is often the wrong target, and how a small amount of protein (or EAAs) before training can change perceived exertion, improve workout output, and potentially increase post-workout energy expenditure—especially in women who are prone to under-fueling. We also dive into muscle quality (not just muscle size), why it matters for insulin sensitivity and body composition, and what changes in peri/post-menopause can mean for amino acid delivery to muscle—and how to train and eat to stay lean, strong, and metabolically resilient.

In this episode, Vanessa sits down with Dr. Nicole Huffman to unpack what's actually happening beneath the surface in midlife: rising insulin resistance, stress-driven blood sugar swings, declining metabolic flexibility, and the silent loss of muscle that lowers resting metabolic rate. They explore why ketosis can be a powerful tool during perimenopause — not as a rigid "diet," but as a metabolic state that stabilizes glucose, reduces inflammation, and helps restore the internal environment hormones rely on. They also explore the powerful connection between ketosis and fertility — including insulin resistance, progesterone signaling, PCOS, and why metabolic "safety signals" matter for ovulation. You'll also hear: Why muscle preservation changes everything after 40 The surprising connection between stress, insulin, and progesterone Why some women regain ovulation when blood sugar improves How to approach keto in a flexible, woman-centered way Why protein + lifting + sleep are non-negotiable Vanessa also shares her experience using protein-sparing modified fasting (PSMF) days to drive fat loss, body recomposition and ketogenesis while protecting lean mass — and why this may be a more effective strategy for women over traditional fasting. If you've ever said, "My body doesn't respond like it used to," this episode explains why — and what to do about it.

Start of episode recap is at 13.41 In today's Friday solocast, Vanessa Spina breaks down the biggest takeaways from her interview with Dr. Paul Moughan—one of the world's leading experts on protein quality, amino acid digestibility, and how much of the protein you eat actually becomes usable by the body. If you've ever wondered why fat loss stalls in a deficit, why muscle can drop even when you "hit your protein," or why metabolic rate seems to slow during dieting—this episode explores a rarely discussed variable: utilizable protein and amino acid delivery to tissues.  🧠 IQBAR – Try the Ultimate Sampler Pack: IQBARs, IQMIX, and IQJOE!

Protein grams don't tell the full story. In this episode, Vanessa Spina is joined by Paul Moughan, a world authority on protein quality and amino acid digestibility, to explore why fat loss can stall and muscle can be lost — even on a high-protein diet. Dr. Moughan, a Distinguished Professor at Massey University and architect of DIAAS, explains why protein absorbed and delivered to muscle matters more than protein consumed.

Start of Arny Ferrando's episode recap is at 14:00 minutes. In today's Friday solocast, Vanessa Spina recaps her recent interview with Arny Ferrando, one of the world's leading experts on human muscle protein metabolism — and explains why fat loss problems are often muscle problems in disguise. The episode opens with two brand-new studies that challenge common fat-loss assumptions, including new findings on hydration and body fat loss, and surprising research linking resistance training with intelligence and cognitive performance. From there, Vanessa distills the most important insights from her conversation with Dr. Ferrando, including why simply eating less often backfires, how aging and hormonal changes impair muscle metabolism, and what most people misunderstand about protein needs, circulation, and metabolic slowdown. 🧠 IQBAR – Try the Ultimate Sampler Pack: IQBARs, IQMIX, and IQJOE!

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!

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.

That belief has shaped how we diet, how we train, and even whether we bother moving more at all. But a brand-new 2025 human study challenges that idea in a way that could completely change how you approach fat loss, daily movement, and exercise. In this Friday recap episode of the Optimal Protein Podcast, Vanessa breaks down the study behind the headlines and explains—in plain English—what the data actually shows, what most people misunderstood, and how to use this information to get better fat-loss results without eating less or training harder.

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 In today's episode, Vanessa sits down with Dr. Howard, the lead author of a brand-new PNAS study that is challenging one of the most widely accepted ideas in human metabolism. For years, many scientists believed that our bodies operate within a fixed daily calorie "budget," and that after a certain point, increasing activity doesn't increase total calorie burn. But Dr. Howard's new research suggests the story may be far more dynamic — and far more empowering — than we ever realized.
