Welcome to The Metabolic Rebellion! In this episode, hosts Dr. Brent Brotzman and Kevin dive into one of the most misunderstood topics in the world of health and nutrition: losing weight the right way. Forget everything you’ve heard about calorie counting, restrictive diets, and trendy weight loss hacks. This episode unpacks why the old “calories in, calories out” model doesn’t work for our bodies - and explains how insulin, not calories, is the real gatekeeper when it comes to burning fat.

You’ll hear their candid conversation on the pitfalls of conventional dieting advice, the science behind fasting and ketosis, and how ancient strategies can be harnessed for modern healing. They tackle rapid-fire questions from listeners about what really matters for fat loss, debunk common myths, and challenge the mainstream narrative pushed by major food companies and influencers alike.

If you’re curious about what fasting actually is and isn’t, how ketogenic diets fit into long-term health, why strength training matters, or whether that morning coffee will break your fast, you won’t want to miss this lively, practical, and evidence-based discussion. Plus, check out the show notes for free ebooks and resources to help you lose weight the right way - no hype, just straight talk.

Welcome back to The Metabolic Rebellion. In today's episode, hosts Dr. Brent Brotzman and Kevin Bury go beyond the headlines, the hype, and the celebrity endorsements to reveal the untold story behind GLP-1 agonist weight loss drugs like Ozempic, Wegovy, and Mounjaro. While these medications promise fast and dramatic change, the reality - according to the latest studies and clinical experience - can be far more concerning.

With a clear, candid conversation, they break down why these widely marketed "miracle shots" might offer more risk than reward: from severe muscle and bone loss, to long-term metabolic problems, accelerated aging, and the disturbing reality of increased mortality. Dr. Brent Brotzman explains the hidden mechanism behind what he calls a "pharmacological starvation diet," examining how these drugs can push users into a dangerous cycle of frailty and metabolic decline.

If you've wondered about the deeper physiological impact of GLP-1 drugs, or if you're searching for real, science-based strategies for sustainable weight loss, this episode pulls back the curtain. Join Dr. Brent Brotzman and Kevin Bury as they give you the truth behind the trending treatments, give you hope for lasting change, and arm you with knowledge on how to protect your health for the long run.

Welcome to The Metabolic Rebellion! In this episode, hosts Dr. Brent Brotzman and Kevin Bury kick off 2026 by taking aim at one of the most entrenched - and misleading - ideas in health and weight loss: the “eat less, move more” mantra. They expose how this slogan, pushed by massive food and beverage companies, has shaped public perception and actually kept us stuck in a cycle of failed diets and frustration.

You’ll hear why calorie restriction - despite decades of popularity - hasn’t solved the obesity epidemic, and why focusing on calories in versus calories out misses the mark when it comes to real human physiology. Dr. Brent Brotzman breaks down the science behind why our bodies aren’t just simple machines and introduces the carbohydrate-insulin paradigm, explaining how the foods we eat affect our hormones, metabolism, and ability to burn fat.

They also highlight how processed foods, artificial sweeteners, and even seemingly “healthy” habits like juicing can undermine weight loss by spiking insulin and making it harder to tap into our fat stores. Plus, they discuss popular trends like GLP-1 medications, and why these might not be the miracle solutions they seem.

If you’re ready to ditch the blame, question broken diet advice, and learn how to truly reclaim your metabolic health, this episode will set the stage for a science-backed, empowering rebellion against outdated weight loss dogma. Tune in and discover how real change starts by thinking - and eating - like your great-great-grandmother.
