How this tool works
Mifflin–St Jeor estimates resting energy; a selected activity multiplier approximates daily maintenance. This tool does not prescribe a calorie deficit or weight-loss schedule. For adults aged 20–100. These are educational estimates, not diagnoses, treatment targets or medication-dosing guidance. They are not designed for children, pregnancy or breastfeeding; body composition and health conditions can make the estimates unsuitable. Discuss personal concerns with a qualified clinician.
