How the maths works
BMR uses the calculator.net formulas: Mifflin-St Jeor (men 10W + 6.25H - 5A + 5, women -161), Revised Harris-Benedict, or Katch-McArdle (370 + 21.6 x lean mass).
Daily burn = BMR x activity level + workouts + steps.
Workouts = (MET - 1) x kg x hours, so your resting burn isn't counted twice.
Steps ≈ 0.0005 kcal x kg per step.
Fat lost = (burned - eaten) / 7,700 kcal per kg.
Each weigh-in updates your BMR from that day on. The scale jumps around with water and food, so the 7-day average is the number to trust.
