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.

Meet our guest

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.

Thank you to our partners Key takeaways
  • Focus on five key drivers like VO2 max, strength, social connections, not smoking & blood pressure instead of chasing 100+ biomarkers
  • Prioritize interventions with the biggest impact on lifespan rather than spending energy on minor or unproven strategies
  • Avoid mistaking correlation for causation by digging deeper into the real reasons behind trends
  • Recognize that the number of social interactions directly influences mortality risk & shouldn’t be overlooked
  • Improve VO2 max & strength through exercise to dramatically cut mortality risk even with simple changes
  • Avoid Goodhart’s Law by targeting true overall strength instead of isolated metrics like grip strength
  • Choose practices with real effects backed by evidence rather than wasting time chasing small wins
  • Optimize both quantity & quality of life by aiming to enjoy more years not just add them
  • Understand that both too much & too little sleep carry risks while exercise may be more influential than sleep alone
  • Rely on interventions supported by strong human evidence like clinical trials & Bradford Hill criteria

Ruthie's Table 4

Ruthie's Table 4

For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
