    Why Stubborn Fat Is So Hard to Lose + Protein-Sparing Fat Loss: Lyle McDonald Recap
    2026/09/25
    Vanessa breaks down the biggest scientific takeaways and most actionable gems from her recent conversation with body-composition expert and author Lyle McDonald. Why does fat come off easily from some areas while other areas seem determined to hold on? And can we influence stubborn fat loss without simply getting leaner everywhere else? Create your own custom protein blend at truenutrition.com/vanessa and use code VANESSA for 20% off your first order. Let Vanessa know what your custom blend is! Now shipping internationally. Vanessa explores the physiology of stubborn body fat, including fat mobilization, blood flow, oxidation and alpha-2 receptors, and why women in particular may notice their upper body becoming lean long before their hips and thighs. She also breaks down Lyle's newest approach, Intermittent Modified Fasting, and how alternating protein-focused, low-calorie days with maintenance days may offer a more flexible way to create a calorie deficit while prioritizing muscle retention. Vanessa explains why protein becomes especially important during aggressive calorie restriction, why a maintenance day is different from a "cheat" or "feast" day, and how meal timing, appetite and ketosis can influence how sustainable a fat-loss phase feels. She also examines Lyle's proposed strategies for addressing stubborn fat—including lower-carbohydrate eating and combining higher-intensity intervals with lower-intensity activity—while separating established physiology from strategies that still require more research. YOHIMBINE SAFETY NOTE: Yohimbine is discussed in this episode for educational purposes only and is not being recommended for use. Yohimbine can cause significant side effects, including anxiety, increased heart rate and blood pressure, and may interact with medications. It should not be used during pregnancy or breastfeeding. Anyone considering yohimbine should first consult with a qualified healthcare professional. Finally, Vanessa explores the scientific mechanisms behind yohimbine and alpha-2 receptors for educational purposes, red-light therapy and blood flow, whether slower weight loss could help preserve facial fullness, and why having a maintenance strategy may be just as important as having a fat-loss strategy.

  • New Study on Creatine During Fat Loss and Body Recomposition: Dr. Drew Gonzalez

    New Study on Creatine During Fat Loss and Body Recomposition: Dr. Drew Gonzalez
    2026/09/28

    Can you lose body fat while gaining lean tissue—even during a calorie deficit? And could the quality of your protein change how well you recover and protect muscle?

    Vanessa is joined by exercise and nutrition researcher Dr. Drew Gonzalez to explore new research on creatine, body recomposition, protein quality, and what it takes to make weight loss more than a lower number on the scale.

    Try my favorite electrolytes! Cure Hydration. Visit curehydration.com/VANESSA and use code VANESSA for 20% off. Now available on Amazon!

    They begin with a 12-week study in middle-aged and older adults that tested creatine alongside exercise and a weight-loss diet. Vanessa and Dr. Gonzalez discuss the promising body-composition findings, why gaining lean tissue is not necessarily the same as gaining that amount of muscle, and what the study can—and cannot—tell us about fat loss and cognitive health.

    They also explore research comparing pork- and soy-based meals during intense training, the role of essential amino acids and leucine when calories are limited, and practical protein targets for people who want to lose fat without unnecessarily losing muscle.

    In this episode:

    • What a new creatine study found about lean tissue and body fat during weight loss
    • Whether someone eating plenty of meat still stands to benefit from creatine supplementation
    • What we know—and don't yet know—about higher creatine doses and brain health
    • Why two diets with the same protein grams may differ in essential amino acid content
    • What Dr. Gonzalez's military cadet study found about protein sources and recovery
    • How much protein to aim for while resistance training and losing body fat
    • Whether protein needs to be evenly distributed across meals
    • What firefighter research reveals about time-restricted eating in demanding real-world conditions
    • Whether probiotics and synbiotics meaningfully add to a structured fat-loss program

    The goal isn't simply to lose weight. It's to improve what you lose—and what you keep.

  • 6 New Science Takeaways on Losing Fat Without Losing Muscle

    6 New Science Takeaways on Losing Fat Without Losing Muscle
    2026/10/02

    Can you gain lean tissue while losing body fat? And if two people eat the same number of protein grams, will they necessarily get the same body composition results?

    In this episode, Vanessa shares six takeaways from her conversation with Dr. Drew Gonzalez on the science of fat loss, muscle retention, protein quality, creatine, and sustainable nutrition.

    BACK-TO-SCHOOL SALE! For a limited time, save 40% sitewide at ketogenicgirl.com⁠ with code BACKTOSCHOOL40, including the Protein-Sparing Modified Fasting Library, ToneLUX Red Light Therapy Collection, and Tone Breath Ketone Analyzer.

    A 12-week study discussed in the interview found that adults combining an exercise and weight-loss program with creatine gained lean tissue while reducing body fat. Vanessa unpacks why that result is exciting, what "lean tissue" actually measures, and why the change in body fat percentage needs careful interpretation.

    In this episode:

    • Why the quality of weight loss matters more than the number on the scale alone
    • What the creatine study found about lean tissue and body fat during a weight-loss program
    • Whether protein quality may matter more when calories are limited
    • What a study comparing pork- and soy-based meals in military cadets found about recovery
    • How much protein Dr. Gonzalez suggests as a practical starting goal for people who resistance train
    • Why you don't need perfectly timed or evenly divided protein meals
    • What firefighter research can—and cannot—tell us about time-restricted eating
    • Where the evidence stands on creatine and cognition, probiotics, and other emerging supplements

    The central question: How can you lose body fat while giving yourself the best chance of maintaining—or even gaining—lean tissue?

    Listen to Vanessa's full interview with Dr. Drew Gonzalez for the complete conversation.

  • Burning Fat vs. Losing Fat: Metabolic Flexibility Explained with Dr. Mike T. Nelson

    Burning Fat vs. Losing Fat: Metabolic Flexibility Explained with Dr. Mike T. Nelson
    2026/10/05

    Does burning more fat for fuel mean you're actually losing more body fat? And if you're in ketosis, does that mean the fat you're burning is coming from your body—or from the food you just ate?

    Today on the Optimal Protein Podcast, I'm joined by Dr. Mike T. Nelson to unpack this important distinction and explore what metabolic flexibility really means for fat loss, muscle preservation, and performance.

    BACK-TO-SCHOOL SALE! For a limited time, save 40% sitewide at ketogenicgirl.com with code BACKTOSCHOOL40, including the Protein-Sparing Modified Fasting Library, ToneLUX Red Light Therapy Collection, and Tone Breath Ketone Analyzer.

    Mike holds a PhD in exercise physiology and a master's degree in mechanical engineering with a focus on biomechanics. In this fascinating conversation, we explore your body's ability to use both carbohydrates and fat, switch between them, and adapt to different demands.

    We discuss why burning more fat during a workout doesn't necessarily translate into greater body-fat loss, why calorie balance still matters, and how your nutrition and training can work together to support body recomposition. I also share my own experience gaining weight on keto despite high ketone readings—and what that taught me about dietary fat versus stored body fat.

    In this episode, we discuss:

    • The three components of metabolic flexibility—and why using carbohydrates effectively matters, too
    • Burning fat versus losing fat: the distinction that can change how you approach your goals
    • How insulin and fuel availability influence what your body burns
    • Why higher ketone readings don't necessarily mean greater body-fat loss
    • Fasted cardio: what the research suggests and where questions remain
    • Long-term keto and the potential tradeoffs for high-intensity exercise
    • Adjusting carbohydrates to support your training performance
    • Protein-sparing modified fasting and the considerations around more aggressive calorie deficits
    • Why stubborn lower-body fat can be especially frustrating for women
    • Protein and resistance training: their roles in preserving lean mass while dieting
    • Building aerobic fitness to support metabolic flexibility over time
    • Heat, cold exposure, and Mike's broader framework of physiologic flexibility
    • Lactate as a valuable fuel and the emerging interest in lactate supplements
    • Tracking performance alongside the scale—and keeping maintenance in mind from the beginning

    I loved Mike's emphasis on building a body that can perform well while you work toward your body-composition goals. This episode is full of thoughtful distinctions to help you better understand the science behind fat loss!

  • 7 Takeaways on Metabolic Flexibility, Fat Burning vs Fat Loss & Protecting Muscle

    7 Takeaways on Metabolic Flexibility, Fat Burning vs Fat Loss & Protecting Muscle
    2026/10/09

    Burn More Fat—But Are You Losing It? 7 Takeaways on Metabolic Flexibility & Protecting Muscle

    Does becoming a better fat burner automatically mean you're losing more body fat? And do higher ketones mean better results?

    In today's episode, I'm unpacking seven of my biggest takeaways from my conversation with Dr. Mike T. Nelson about metabolic flexibility, sustainable fat loss, and protecting your hard-earned muscle.

    I'm sharing what I learned the hard way during my own keto journey—including how I gained weight despite having high ketones—and why understanding the difference between burning dietary fat and losing stored body fat can change how you approach your goals.

    We're also exploring how to adjust carbohydrates to support your training, why fasted cardio is optional, and how small, manageable food changes can help you make progress while still enjoying your meals and your life!

    In this episode, we explore:

    1. What metabolic flexibility really means: Using fat and carbohydrates effectively and switching between fuels as your needs change.
    2. Fat burning versus fat loss: Why increased fat oxidation and higher ketones don't automatically mean you're losing stored body fat.
    3. Calories, hunger, and sustainability: Why an energy deficit matters—and why how you feel while creating it matters, too.
    4. Matching carbohydrates to your training: How your activity, intensity, preferences, and recovery can guide your fueling choices.
    5. Fasted cardio and the "fat-burning zone": Why the fuel you use during a workout doesn't tell the whole story about long-term fat loss.
    6. Protecting muscle while losing weight: The combined importance of protein, resistance training, and recovery, plus a discussion of protein-sparing modified fasting and its limitations.
    7. Building capacity beyond the scale: Tracking strength, aerobic fitness, energy, and recovery alongside changes in body weight.

    I also share the gentle nutrition adjustments I'm making during breastfeeding and why this is a different approach from aggressive dieting or protein-sparing modified fasting.

    You don't have to optimize everything at once. Choose one takeaway you can put into practice this week—whether that's tracking your weights and reps, making a simple food swap, or fueling your workouts in a way that helps you feel your best.

  • T2 and Fat Burning: What the Thyroid Research Really Shows with Dr. Amie Hornaman

    T2 and Fat Burning: What the Thyroid Research Really Shows with Dr. Amie Hornaman
    2026/10/12
    What is T2, and why have researchers been investigating its effects on metabolism? In this episode of the Optimal Protein Podcast, I'm welcoming back Dr. Amie Hornaman to explore 3,5-diiodothyronine, commonly called T2—a lesser-known thyroid hormone derivative studied for its effects on energy expenditure, fatty acid oxidation, and mitochondrial function. Thank you to our sponsor, AirDoctor! Visit ⁠AirDoctorPro.com and use promo code VANESSA for up to $300 off select AirDoctor models, plus a free 3-year warranty. All AirDoctor air purifiers come with a 30-day money-back guarantee. We walk through research on liver cells, skeletal muscle, and brown fat, unpacking the machinery that helps fatty acids enter the mitochondria and a process called mitochondrial uncoupling, in which energy is released as heat. We also explore possible connections with ketogenic diets and the question that matters so much to us here: what could these findings mean for losing body fat while preserving muscle? Much of the research discussed comes from animal studies. We examine a small human report involving just two participants, and Amie shares observations from an uncontrolled group of 14 women who used her T2-containing product. These findings raise interesting questions, but they do not establish that supplemental T2 is a safe or effective approach to fat loss. BACK-TO-SCHOOL SALE! For a limited time, save 40% sitewide at ⁠ketogenicgirl.com with code BACKTOSCHOOL40, including the Protein-Sparing Modified Fasting Library, ToneLUX Red Light Therapy Collection, and Tone Breath Ketone Analyzer.

Important context for interpreting the research The approximately 50% lower fat mass reported in the 2005 rat study was a comparison with the untreated high-fat-diet group. It does not mean the animals lost half of their starting body fat. The 2011 human report described approximately 4% lower body weight, not proof that all weight lost was fat. Neither that report nor the uncontrolled 14-woman project establishes long-term safety or that T2 caused the reported changes. Changes in muscle-cell fuel use do not establish muscle preservation during weight loss. Shared metabolic pathways also do not establish that combining keto and T2 provides additional benefits.

  • T2, Fat Burning & Brown Fat: How It Works in the Mitochondria and What the Studies Show

    T2, Fat Burning & Brown Fat: How It Works in the Mitochondria and What the Studies Show
    2026/10/16
    Does increasing fat burning automatically mean losing more body fat? And what would we need to measure to know whether an intervention preserves muscle? In this Friday solocast, I'm revisiting my conversation with Dr. Amie Hornaman to unpack the research on T2, a lesser-known thyroid hormone derivative, and connect the mechanisms to the body composition questions we care about. We go inside the mitochondria to explore how fatty acids enter, how our cells regulate fuel use, and how mitochondrial uncoupling releases energy as heat. I also revisit the brown fat research and potential connections with ketogenic metabolism. Along the way, I clarify several findings from the interview—including what "50% less fat mass" meant in the rat study, why lower body weight does not establish fat-only loss, and why changes in muscle-cell metabolism do not prove muscle preservation. The T2 research is intriguing, but human evidence remains very limited.

  • The Stubborn Fat Solution: How to Mobilize Lower-Body Fat with Lyle McDonald

    The Stubborn Fat Solution: How to Mobilize Lower-Body Fat with Lyle McDonald
    2026/09/21
    Why does body fat disappear quickly from certain areas while seeming almost impossible to lose from others? BACK TO SCHOOL SALE! For a limited time, save 40% sitewide at ketogenicgirl.com with code BACKTOSCHOOL40, including the Protein-Sparing Modified Fasting Library™, ToneLUX Red Light Therapy Collection and Tone Breath Ketone Analyzer. Australia, New Zealand & Southeast Asia: Save 75% on available ToneLUX and Tone products during the warehouse moving sale with code WAREHOUSE75, while supplies last. In today's episode of the Optimal Protein Podcast, Vanessa welcomes renowned author and body-composition expert Lyle McDonald to explore the fascinating physiology of stubborn body fat. Where we store our most resistant fat varies from person to person. For some women, it may be concentrated around the hips and thighs; for others, it may be the abdomen, arms or another area. Men may also struggle with stubborn fat, commonly around the abdomen and lower back. Lyle explains how differences in alpha-2 and beta receptors, blood flow, insulin sensitivity and catecholamine activity can make certain fat stores more difficult to access than others. They break down the three essential steps required to lose stored body fat: mobilizing fatty acids from the fat cell, transporting them away and ultimately oxidizing them for energy. Try my favorite new electrolytes, Cure Hydration! Head to curehydration.com/VANESSA and use code VANESSA to save 20% on your order. 💙 Now available on Amazon! Vanessa and Lyle also discuss whether low-carbohydrate eating, ketosis, high-intensity intervals and strategically timed low-intensity activity may help improve stubborn-fat mobilization. Lyle introduces his new book, Intermittent Modified Fasting, and explains how alternating protein-sparing modified fasting days with maintenance days may support fat loss, muscle retention, training performance and long-term adherence—without dieting continuously. Yohimbine can cause anxiety, increased heart rate, blood-pressure changes and other adverse effects, and may interact with medications. This podcast discusses the scientific rationale behind alpha-2 receptor antagonists, including yohimbine, for educational purposes only—not as a recommendation for use. Yohimbine is not appropriate for everyone, particularly people with certain medical conditions, and should not be used during pregnancy or breastfeeding. Consult a qualified healthcare professional before considering its use. In this episode, they discuss: • Why certain areas of body fat are more resistant than others • How stubborn-fat patterns differ between individuals • Why some women struggle most with hip and thigh fat • Why the abdomen and lower back are common stubborn areas in men • Alpha-2 versus beta receptors and how they affect fat mobilization • Why blood flow matters when attempting to access stubborn fat • The three steps required to mobilize and burn stored body fat • Why the face and upper body may become lean before stubborn areas • Whether slower weight loss may help preserve facial fullness • How low-carbohydrate eating may influence alpha-2 receptors • Why high-intensity intervals may improve stubborn-fat mobilization • Pairing short intervals with low-intensity cardio or walking • Why a calorie deficit is still required for net fat loss • Protein-sparing modified fasting versus conventional fasting • Why many alternate-day fasting plans provide too little protein • How to alternate modified fasting days with maintenance days • Why "maintenance day" may be more helpful than "feast" or "cheat day" • Using PSMF days to support long-term weight maintenance • Ketosis, appetite suppression and the metabolic fasting response • Yohimbine HCl, alpha-2 receptors and important safety concerns • Pregnancy, breastfeeding and changes in female fat distribution If you have ever wondered why one part of your body becomes lean while another area remains frustratingly resistant, this episode explains the biology of stubborn fat—and the strategies that may help create a more balanced pattern of fat loss.
