How It Works

Mifflin-St Jeor Equation: Considered the standard for calculation since 1990. It is generally the most accurate for people with average body composition.

Revised Harris-Benedict: An older formula (revised in 1984). It tends to overestimate calorie needs slightly compared to Mifflin-St Jeor.

Katch-McArdle: Considered the most accurate if you know your exact Body Fat Percentage, as it bases the calculation on Lean Body Mass (LBM) rather than total weight.
