In this episode, Dr Mauricio Gonzalez explains why the real measure of metabolic health is happening inside your liver, and why that single shift changes how we should think about weight loss, GLP-1 medications, and longevity. Dr Mauricio Gonzalez is a triple board-certified physician in internal, emergency, and obesity medicine, and a current endocrinology fellow practising in New York. He is one of the most trusted medical voices online, and he brings a grounded, clinic-first perspective to a field that is often dominated by hype. In this episode, we discuss: - Why isolated blood tests and blood pressure readings tell you very little - The myth that GLP-1 medications are "the easy way out" - Why liver fat may matter more than body weight - How diabetes clinics now remove medications instead of adding them - Choosing between the growing menu of GLP-1 options, and why lower doses can work - Which supplements are worth taking, and which Mauricio has cooled on - The minimum effective dose for exercise, and when "enough" beats optimising 00:00 Intro 02:18 Minimum Effective Dose for Exercise 7:56 Why Continuity of Care Reduces Mortality 10:02 How Type 2 Diabetes Silently Develops Over 12 Years 12:46 Statin vs. PCSK9 Inhibitor: How Doctors Choose 20:34 How GLP-1 Drugs Transformed the Diabetes Clinic 30:23 Why Doctors Now Measure Organ Fat, Not Body Weight 33:33 How Fatty Liver Disease Is Diagnosed 39:13 How Liver Fat Drives Insulin Resistance 45:25 Wegovy vs. Zepbound: How to Choose a GLP-1 48:47 Should Lean People Use GLP-1s for Metabolic Health? 52:44 Why Patients Feel Guilty Taking GLP-1s 1:01:29 How Mauricio’s Nutrition Advice Has Evolved Over a Decade 1:06:27 Supplements on GLP-1s: What's Worth Taking 1:11:35 Minimum Effective Dose for Resistance Training 1:18:57 When Health Optimization Becomes Counterproductive To connect with Dr Mauricio Gonzalez, follow him on https://www.instagram.com/dr.mauriciogonzalez, https://x.com/drmauinforma, and https://www.youtube.com/@doctormauinforma, or visit his website at https://www.drmauriciogonzalez.com/.
