Why Liver Fat Matters More Than Weight | Dr Mauricio Gonzalez
6/22/20261 hr 30 min
For decades we have treated the number on the scale as the goal of metabolic health. Dr Mauricio Gonzalez, a triple board-certified physician and endocrinology fellow practising in New York, makes the case that we have been measuring the wrong thing.
In this conversation we explore why liver fat, not body weight, is becoming the real target, what the latest weight-loss medications can and cannot do, and how to cut through the hype and dogma that surround this field.
What we cover:
- 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
- Which supplements earn their place, and which Mauricio has cooled on
- The minimum effective dose for exercise, and knowing when "enough" is enough
A grounded, practical conversation with a doctor who meets people where they are. If you enjoy the show, please take a moment to rate and review The Proof on Apple Podcasts or Spotify, it genuinely helps more people find these conversations.

There's a strange tension in how we talk about metabolic health right now in 2026. On one side, GLP-1 medications are reshaping obesity medicine faster than almost anything, at least in my lifetime. On the other side, more and more people are getting their health information from social media, where nuance tends to be the first casualty and where the loudest voice usually wins over the most accurate one. At a time when we have some of the best interventions available to humankind to turn our health around, we're also increasingly being sold things based on half-truths, storytelling, and fabrications of the evidence. My guest today sits right in the middle of this, and that's why I wanted to talk to him. Dr. Mauricio Gonzalez, or Dr. Mau, as millions know him by, is an internal medicine physician currently completing a fellowship in endocrinology and one of the most followed doctors in the Spanish-speaking world. He's built that community and earned its trust by translating rigorous science into something people can actually use. In this conversation, we get into how he actually treats patients in the real world, when diet comes first and when a medication does, how to eat well on a GLP-1, the striking new data on these drugs and the liver, and where he thinks the diet wars, both low carb and plant-based alike, get it wrong. If you enjoyed my conversations with Federico Amati and Valter Longo, this one sits right alongside them.
