About Myopedia

Myopedia is a small set of client-side fitness calculators — TDEE, macros, body fat, protein intake, intermittent fasting, and one rep max. Each one gives you a clear answer fast.

Who's behind it

Myopedia is built and maintained by Jack Galway, Founder. It's small and fast by design — each calculator does one thing, runs in your browser, and gets out of your way.

Why we ask sex assigned at birth on some calculators

The TDEE calculator and body fat calculator ask for sex assigned at birth because their formulas — Mifflin-St Jeor and the US Navy method — are defined with two values and use that input only in the equation.

There's no validated third coefficient, so adding a third option would mean inventing numbers. Calculators whose math doesn't depend on it — one rep max, protein intake, intermittent fasting, and the macro split — don't ask at all.
