Think more data means better health?

Dr. Zain Hakeem challenges the obsession with endless biomarkers & breaks longevity down to its core drivers. You’ll see how effect size, simplicity, consistency, beat the latest trends & how to bioharmonize your lifestyle around what truly works.

Dr. Hakeem is a dual board-certified physician in Internal Medicine & Pediatrics, with a background in philosophy from LSU & a medical degree from Texas College of Osteopathy. He practices both primary & hospital medicine, blending acute care insight with preventative strategies.

He’s the creator of the Rx-Bayes app, which helps doctors interpret diagnostic accuracy through a statistical lens. On his YouTube channel, he breaks down health misinformation, explores true longevity optimization, & discusses why meaning is essential to living well.
