Your actual needs depend on genetics, body composition, medical conditions, sleep, and other factors this calculator can't measure. Use the output as a starting point, track your weight and energy for 2–3 weeks, and adjust accordingly. If you have a medical condition (thyroid disorder, diabetes, eating disorder history, pregnancy), consult a registered dietitian before changing your intake.
