    Cunningham Calculator

    BMR formula designed for very lean athletes and bodybuilders

    How the Cunningham Formula Works

    Developed specifically for very lean individuals with low body fat percentages, this formula provides higher BMR estimates than other equations. It's most accurate for competitive athletes and bodybuilders in contest preparation.

    Cunningham: BMR = 500 + (22 × lean body mass)
    Lean Body Mass: Weight(kg) × (1 - body fat %/100)
