• Why You’re Gaining Fat on Keto: Craig Emmerich on Insulin Resistance, Fat Cells & Real Fixes

  🎥 In this episode, Dr. Brian Mowll is joined by Craig Emmerich to unpack the real roots of insulin resistance, why simply eating low carb isn’t enough, and what most people get wrong about fat loss. Craig explains the “personal fat threshold” and how the size—and not just the number—of your fat cells may determine your metabolic health. They also dive into protein prioritization, satiety, and how simple shifts can dramatically improve insulin sensitivity.Why You’re Storing Fat (Even on Keto)Craig breaks down why excess fat storage is less about carbs and more about overwhelmed fat cells. It’s possible to become insulin resistant—even without eating sugar—if your fat cells are full and can’t accept more. This flips the script on the traditional carb-insulin model and explains why even lean people can develop type 2 diabetes.How to Shrink Fat Cells and Build Metabolic FlexibilityFat cells need to be “small and happy,” not stuffed. The key to reversing insulin resistance is improving your body’s storage capacity for energy—through fat loss and muscle gain. Craig shares how cutting dairy and nuts, using protein-sparing modified fasts, and strength training all help restore insulin sensitivity and balance hunger hormones like leptin.Why Whole Foods and Protein Still WinDespite debates in the low-carb space, Craig emphasizes that success comes from prioritizing protein, eating real food, and avoiding fat-carb combos—especially ultra-processed ones. He also discusses how creatine can improve not just muscle mass, but also sleep, mental health, and energy levels.The Bottom LineFat loss and metabolic health aren’t just about carbs or calories—they’re about how your body processes energy. If your fat cells are full and your muscle mass is low, no diet will fix that. This episode gives you a science-based, practical roadmap to restore insulin sensitivity and reclaim your health.Key Takeaways5:24 – Why overfilled fat cells trigger insulin resistance11:48 – Personal fat threshold: why even lean people get type 2 diabetes17:32 – What the carb-insulin model gets wrong22:55 – The dangers of ultra-processed fat-carb combos30:44 – Why protein drives satiety and fat loss35:20 – How overeating fat can backfire on low-carb diets42:01 – The impact of cutting dairy and nuts46:00 – The surprising mental health benefits of creatineResources:📘 Website: www.ketomaria.com📗 Craig & Maria’s books & coaching: www.keto-adapted.com📕 Craig’s resource hub: www.ketomaria.com Support the show Support the show

Drawing from his book Lies I Taught in Medical School, Dr. Lufkin challenges conventional thinking on diabetes, aging, and metabolic health—and shares the lifestyle interventions that actually work.Why Most Chronic Diseases Are Lifestyle-DrivenDr. Lufkin explains why diseases like type 2 diabetes, heart disease, and even Alzheimer’s are often preventable and reversible—not through pills, but through intentional lifestyle changes. He unpacks the science behind metabolic dysfunction and how our current healthcare system misses the root cause.Rethinking Medical EducationMedical school trains doctors to manage disease, not reverse it. Dr. Lufkin shares how this training impacted his own health, what finally made him question the system, and why he believes the future of medicine lies in nutrition, movement, and personalized care—not prescriptions.The Power of PreventionFrom fasting and plant-forward eating to sleep, stress, and social connection, Dr. Lufkin outlines the six pillars of lifestyle medicine that form the foundation for lasting health. He explains how small, consistent changes can drastically reduce disease risk and even turn back the clock on aging.The Bottom LineChronic disease isn’t inevitable—and it’s not your destiny. With the right tools, mindset, and support, it’s possible to take control of your health and rewrite your future. Dr. Lufkin’s message is clear: the cure isn’t coming in a pill.

They discuss the key principles of satiety, how to structure your diet for metabolic health, and why exercise is the missing link for many struggling with weight loss.Why Energy Balance Is the Key to Reversing DiabetesMany people believe solving type 2 diabetes is just about cutting carbs, but Dr. Naiman breaks down why it’s really an issue of energy toxicity. When your liver, muscles, and fat cells are overloaded, blood sugar rises—and the solution isn’t just about restricting carbs but also improving how your body burns and stores energy.How to Eat for Satiety and Metabolic HealthDr. Naiman shares his latest insights on choosing foods that keep you full while lowering your overall calorie intake. He explains why prioritizing protein, fiber, and low-energy-density foods is the best way to improve insulin sensitivity, lose fat, and maintain muscle mass.The Role of Exercise in Fixing Your MetabolismDiet alone isn’t enough. Dr. Naiman emphasizes that if you’re struggling to lose weight or keep it off, you’re likely missing the exercise component. He reveals how increasing your energy expenditure through strength training and cardio can make all the difference in appetite control and long-term fat loss.The Bottom LineThe secret to lasting metabolic health isn’t extreme dieting—it’s about balancing protein, fiber, and energy intake while staying active. This episode unpacks the latest research and practical strategies to help you take control of your blood sugar and body composition.Key Takeaways6:42 – Why type 2 diabetes is an energy storage issue12:15 – The best foods for satiety and fat loss18:27 – How to balance protein, carbs, and fats for blood sugar control24:49 – The problem with ultra-processed, high-fat foods32:10 – The exercise strategies that actually improve insulin sensitivity38:21 – How to sustain weight loss without metabolic slowdownResources:Website: tednaiman.com/YouTube: www.youtube.com/@tednaimanInstagram: www.instagram.com/tednaimanBooks: https://www.amazon.com/stores/author/B08124ZVZ6www.dietdoctor.com/authors/dr-ted-naiman-mdSupport the show Support the show
