A Prescription Is Just the Beginning

Before the PhD. Before Precision Nutrition. Before a career that has helped over 100,000 people transform their bodies and their lives, Dr. John Berardi was just a kid who didn’t make the sports teams.

Until one person saw him differently. Not for what he wasn’t, but for who he could become. That moment set in motion a lifelong obsession with one question: to what extent do we have the power to change our bodies, and if we change our bodies, what else changes with them?

He brought that question to our Your Health Matters Summit 2026. And his answer, in 2026, runs straight through GLP-1 medications.

A quarter of a milligram. Once a week. An amount you can barely see with the naked eye, and yet it’s doing something that a hundred years of willpower narratives couldn’t. Dr. Berardi tried Wegovy himself. Within 48 hours, a lifelong food preoccupation simply went quiet. “If I had lost almost no weight,” he said, “just to have my brain working the way it’s working, I would stay on this medication forever.”

But he was equally clear about what the medication alone cannot do. Many people on GLP-1s are losing weight and still not thriving, exhausted, depleted, and wondering why the life they imagined still feels out of reach. His explanation is rooted in nutrition science: when appetite drops dramatically, so does nourishment. Protein, vitamins, sleep, muscle, all of it suffers. And without the right support alongside the medication, the gap between lighter and better can be wide.

“Prescribing without coaching,” he told the room, “is leaving the most important part undone.”

Following the Summit, Dr. Berardi was interviewed by Healthing, and his perspective has since been picked up by the National Post, Ottawa Sun, Vancouver Sun, and other major national publications.
