>> A study from the University of North Carolina in 2018 concluded that up to 88% of Americans have abnormal metabolic function.
Interesting! I'd been going on Gerald Schulman's estimate of 50-60% But he was talking about insulin resistance, which is just one (albeit the most common) metabolic disorder.
A few months ago, he did a podcast interview with Dt Peter Attia. If you have a way to listen to podcasts, I highly recommend it as there's a lot of what cellular mechanism is causing this covered there.
