A Biochemist Reversed His Own Heart Plaque - Here’s How He Did It

3.3K views · 3w ago · 56:49

In this episode, I’m re-airing my conversation with biochemist and engineer Patrick Theut about how he cleared the plaque from his own heart. Patrick was 48, winning 5Ks and playing ice hockey when he passed every test in a Mayo Clinic physical, then asked for one more scan they said he didn’t need. It came back with his left main artery lit up, and a cardiologist gave him four years to live. I went through something very similar myself, which is why this one stuck with me.

How to Stop Losing Muscle on GLP-1s (But Still Burn the Fat)

2.1K views · 1mo ago · 58:41

Guest: Dr. Tyna Moore

I'm re-airing my conversation with Dr. Tyna Moore about GLP-1s because almost everything she said about them is still being misunderstood, and she was one of the earliest voices advocating for using these drugs at very low doses. When we recorded, the internet had largely decided GLP-1 agonists were terrible: muscle wasting, "Ozempic face," suicidality, and more. Tyna's take was very different, and much of what she discussed has held up surprisingly well.
