About KcalMath

KcalMath exists because calorie calculators shouldn't be mystery boxes.

Most fitness calculators give you a number with no formula, no sources, and an email gate in front of the result. This site does the opposite: five calculators, the published equations behind them shown on every page, and a methodology page listing every constant with its citation. No accounts, no gates.

It is an educational tool, not medical advice — the equations are population estimates, and your real-world weight trend over a few weeks always outranks any formula. Questions or corrections are welcome via the repository owner listed in the site records.
