How to Lose Weight and Fix Your Metabolism in 2026

Dr. Mauricio Gonzalez, an internal medicine physician completing an endocrinology fellowship in New York, sits at the intersection of two opposing forces in metabolic health: GLP-1 medications that are reshaping obesity medicine faster than anything in recent memory, and a social media environment where nuance is the first casualty. Board-certified in internal medicine, emergency medicine, and obesity medicine, Gonzalez treats patients in both a private practice and a hospital setting, and he has built a large Spanish-speaking online community by translating rigorous science into usable advice. In this conversation with Simon Hill, he walks through how he actually treats patients in the real world—when diet comes first, when medication does, how to eat well on a GLP-1, and where he thinks both low-carb and plant-based dogmas get it wrong.

Show Notes

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.
