Things to check
Simple division by the energy per kg you enter. Metabolic adaptation is ignored, and this is not advice on intake or weight-loss speed.
The starting values are examples, not recommendations. Check the units and replace them with your own values.
Health estimates are for reference and cannot diagnose or replace medical advice.
