I was recently interviewed by Bold Journey about the work behind The Nutrition Clinic, the experiences that shaped my approach to health, and why I believe the future of healthcare needs to become far more precise.

One of the central themes of the conversation is something I see repeatedly in my work:

People can remain highly functional long after their biology has started moving in the wrong direction.

This is particularly relevant for founders, executives and leadership teams.

Someone can still perform, make decisions, lead a company and deliver results while simultaneously dealing with declining energy, disrupted sleep, blood sugar instability, hormonal changes, inflammation, nutrient depletion or chronic physiological stress.

The problem is that these changes rarely arrive with a clear warning sign.

By the time performance is visibly affected, the underlying biological shift may have been developing for years.

Anyone who listens to Andrew Huberman - which admittedly I do from time to time, as he is great at communicating science to the masses - has sat through the sponsored bit where blood tests for heavy metals are framed as a detox compass. To be frank: This sponsored bit is pretty impressive confidence for inaccurate science. And it hurts my soul.

As someone who routinely screens and treats clients for environmental toxins for over a decade, this is just not right.

Blood heavy metals reflect what you ate yesterday. Sushi today, panic tomorrow - according to blood test. Skip fish for a few days, miracle recovery - also according to blood test. That’s simply temporary exposure and has nothing to do with toxic body burden.
