Estimate insulin resistance when you do not have a fasting insulin value.

Estimate your risk of non-alcoholic fatty liver disease (MASLD) — the silent epidemic.

A better predictor of metabolic risk than BMI — you only need a tape measure.

Estimate your risk of developing type 2 diabetes within 10 years.

Translate your HbA1c percentage into estimated average blood glucose.

See which physiological phase your body is in as you fast.

How much a food actually raises your blood sugar — quantity matters, not just type.

Estimate your daily energy — but read why this number probably is not the answer.

The classic body mass index — useful, but it cannot see visceral fat. See why your waist matters more.
