About this episode

Ian Clark interviews nutrition biochemist Sarah Morgan to discuss peptides, bioregulators, and the complexities of GLP-1 in relation to weight loss.

Ian sits down with Sarah Morgan — a nutrition biochemist who trained for medicine before pivoting into functional nutrition, genetics, and peptide education — to cut through the confusion around peptides, bioregulators, and GLP-1s. They cover what these molecules actually are, why the body already makes them, the real story behind GLP-1 weight regain and "cellular memory," why weight loss is the wrong metric to obsess over, and why none of this replaces sleep, nutrition, movement, and human connection. Peptides and bioregulators aren't foreign substances — the body produces thousands of them daily, and most of what's being introduced through supplementation is supporting a signaling process the body is already designed to run. GLP-1 molecules aren't inherently good or bad; the outcome depends on dose, purpose, and what else is (or isn't) being addressed alongside them. Weight regain after stopping GLP-1s isn't a willpower failure — it's tied to an epigenetic "cellular memory" that can take years to fully reset. And no peptide protocol replaces the fundamentals: quality sleep, real food, movement, and genuine human connection. Connect with Sarah Morgan Website & Social…
