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.
