Fast Keto With Ketogenic Girl

Is fasting really the best way to lose fat — or is there a smarter, more strategic approach? In this masterclass episode, Vanessa introduces a powerful new concept: Protein Fasting — a structured approach using PSMF (Protein-Sparing Modified Fast) days to optimize fat loss, suppress appetite naturally, protect muscle, and potentially tap into fasting-like cellular signaling.

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" matt

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. 

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.

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 utilizat

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.

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 surpris

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.

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.

This episode explores why so many people lose muscle when dieting, how PSMF and ketosis fundamentally change the equation, and what most fat-loss advice gets wrong.
