“Keep your waist to less than half your height” is a boundary drawn from screening studies, not a biological switch. Where 0.5 and the higher 0.6 band come from, what the studies behind them measured, and where the same number means less than it seems.
A raised fasting glucose next to a normal HbA1c, or the reverse, does not by itself mean either result is wrong. The two tests reflect different things, and some conditions shift HbA1c without any change in blood sugar.
Liver fat is usually an incidental finding, and what drives the prognosis is not the fat but the fibrosis stage. What changed in the name of the diagnosis, how stage is measured, what has actually been tested — and why the pharmacy shelf fails a single question about endpoints.
