Formula & Calculation Methodology

Combines Harris-Benedict BMR with granular activity breakdowns (desk job vs standing vs active labor) plus specific resistance training frequency.

Formula Model: Comprehensive Energy Requirement Matrix

Practical Example & Interpretation

A 35-year-old nurse (high occupational steps) who lifts weights 3x/week requires significantly higher calories (~2,400 kcal) than a desk worker with identical gym frequency (~2,000 kcal).

Assumptions & Clinical Disclaimers

Use this tool to establish your starting intake baseline for a 14-day tracking phase. Refine targets as your biofeedback (sleep, hunger, gym strength) guides you.
