"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.
Lily Johnston, MD MPH hosts Knife Down, a health show with 44 episodes published.

What's the optimal ApoB level to reduce Alzheimer’s risk? Is lifestyle or genetics more important? And what does a pTau217 result actually mean for your brain health? In this Brain Health Q&A, I answer your questions abo
If you've been told APOE4 means you're destined for Alzheimer's, the science says something very different. As a vascular surgeon who has spent years treating the end-stages of preventable disease, I want to give you a c

You asked 349 questions about my LDL video. I'm answering the ones that matter most — including who paid for the study. Last week I broke down the LDL cholesterol trial. The comments flooded in — and several of you asked
A common cholesterol drug might protect your brain from Alzheimer's — but I read the actual study, and there's a red flag nobody is talking about. Nick Norwitz covered this story. I went further — I pulled the original p
