About

I’m Dr. Lily Johnston, a vascular surgeon on a mission to put myself out of business. After years of treating the end-stages of heart disease—bypass surgeries, stents, amputations—I realized something brutal: Almost all of it was preventable. So now I teach the part of medicine we should have been taught all along: ✅ How to prevent heart attacks and strokes ✅ How to fix metabolic dysfunction (even when your labs look “normal”) ✅ Why weight loss isn’t a willpower problem ✅ When lifestyle changes are enough—and when you need medication ✅ How sleep, nutrition, stress, movement, hormones, and connection shape your heart and health This isn’t influencer wellness. This isn’t fear-based medicine. It’s real prevention, real science, real hope. If you’ve been “doing everything right” and still not seeing results… you’re my people. Subscribe and let’s make chronic disease optional.

Video Description

Cholesterol isn’t the villain you were taught to fear — it’s the fuel. And in this video, I’m breaking down why fuel isn’t the same thing as fire, and why most people are fighting the wrong battle when it comes to heart disease. If you’ve ever stared at your LDL number and wondered, “Is this actually going to kill me?” — this one’s for you. Most people obsess over cutting down a few trees… while ignoring the raging sparks flying everywhere. In this episode, we cover: ✔️ Why LDL/ApoB matters — but why it’s only one piece of the risk puzzle ✔️ The metabolic “weather conditions” that turn plaque from slow embers into a wildfire ✔️ Why early detection (CAC, CIMT, CCTA) is the missing link in prevention ✔️ How to think like a surgeon when interpreting risk ✔️ And how to stop managing numbers and start managing danger If you’re trying to understand your risk — not the average person’s — hit play.
