🎧 Stay tuned to find out:
➡ Why so many supplements don’t contain what the label says
➡ The “essentials” most people are missing (and how to test for them)
➡ Why gummies are often just expensive sweets
➡ The supplement mistake that can mess with blood tests, surgery and medications

We track our steps, sleep, calories… even glucose. So why are we STILL getting sicker?

In this episode, Dr Karan sits down with Josh Clemente (former SpaceX engineer and founder of Levels) to explore a big question: Are health wearables actually helping us, or are we just collecting data with no real direction?

Josh explains why aerospace treats “health” totally differently to medicine, why we should measure when we’re healthy (not just when things go wrong), and what “biological observability” could mean for the future of healthcare.

🎧 Stay tuned to find out:
➡ Why “if you’re healthy, there’s no reason to measure” is backwards
➡ What SpaceX taught Josh about monitoring systems vs monitoring humans
➡ Why data is neutral (and why interpretation is everything)
➡ The biggest risks of wearables: anxiety, obsession, disordered habits
➡ Why CGMs can be powerful, but easy to misuse without context
➡ What a real “health operating system” might look like in 3–10 years
➡ The uncomfortable truth about health inequality and the future of tech
