How this tool works
The equation predicts resting energy expenditure, commonly presented as BMR. It is not a measurement of your metabolism or a recommended daily food intake. 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.
