Yes, but it de-prefs it as I understand it, and refines the model with better, more fine grained objective measures. There's room in this new space for a "fat, but fit" category.

I don't mind keeping BMI any more than I mind GPs hitting my knee with a hammer. That isn't the only way they measure reflexes these days. I do mind BMI alone being used to determine health pathways.

(not a medico so this is outside-view)
