About Health Calculator
BMI is a population screening figure and carries no information about body composition, so it misreads muscular and older bodies in opposite directions. All three outputs are estimates for planning, not a substitute for a clinician.
Estimate your Body Mass Index, daily calorie needs using the proven Mifflin–St Jeor formula, and a pregnancy due date from your last menstrual period. It brings three common health estimates together so you can plan diet, fitness and milestones quickly.
These figures are informational estimates rather than medical advice — take decisions about your health with a clinician. Calorie targets especially are a starting point to adjust against real results, since activity level is self-reported and easy to overstate.
