A field manual for the human machine.

MyBodyAge exists because the internet is loud, and the actual science of metabolic health is quiet. We write for the people doing the work: athletes, lifters, biohackers, women navigating the endocrine cliffs of perimenopause, and anyone who suspects their body deserves the same rigor they apply to their career.

Every article is written by a clinician or researcher, edited against the peer-reviewed literature, and stripped of the wellness varnish that has infected the category. No supplement stacks we don't personally take. No affiliate codes. No promises we can't defend at a conference.

If you're new here, start with the Metabolic Age Test. It takes 60 seconds and will tell you where your habits are compounding for you and where they're compounding against you.
