Knife Down
"Knife Down" is what a surgeon says in the OR when she puts her scalpel down so no one gets hurt — and it’s the mission here: put the knife down, long before anyone needs to use it.
Knife Down is a podcast about how to actually invest in your health so you can live longer, stronger, and with less time in doctors’ offices. The core focus is the world’s leading cause of death—cardiovascular disease—and what to do about it before it shows up as a catastrophe.
Hosted by a vascular surgeon on a mission to put herself out of business, the show translates cutting-edge science on prevention, metabolic health, and longevity into real-world strategies you can use in clinic or at your kitchen table. Expect evidence, nuance, and zero wellness hype—plus the occasional dark joke about the state of modern medicine.

When "Healthy" Is a Lie: @DrFordBrewer on Insulin Resistance, Hidden Plaque & His Prevention Pivot
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
• Feeling “healthy” is not a screening test.
In this episode, Dr. Ford Brewer ( @DrFordBrewer ) tells the origin story: an ER doc who believed he was doing the right things—until he actually checked and found plaque. That discovery didn’t just change his health plan. It changed his entire job. He walked away from the adrenaline economy of emergency medicine and moved into cardiovascular prevention and teaching, because patching crises is not the same as stopping them.
We talk about:
• The moment “I’m fine” stopped being believable
• Why coronary heart (vessel!) disease continues to go undetected in millions of people
• How statins fit into prevention (and why the decision isn’t one-size-fits-all)
• Low-carb vs low-fat diets for cardiometabolic health—what Ford has learned over time
• Lifestyle vs medication: what actually moves risk in the real world
• How Dr. Brewer built a prevention mission and a YouTube channel to teach at scale
• What he wants you to understand before you become “a patient”
