What this is and is not. The figures come from the Mifflin-St Jeor equation multiplied by an activity factor. It is a population average, not a measurement of you: real requirements vary substantially with body composition, genetics, medication, health conditions and how accurately anyone estimates their own activity. Treat the maintenance number as a starting reference point only. This tool deliberately does not suggest a deficit, a target weight or a timeline — those depend on your circumstances and are worth discussing with a doctor or registered dietitian, particularly if you have any history of disordered eating or a medical condition affecting weight.
