Use BMI and calorie estimates

Enter measurements, units, lifestyle, and a goal to review Classic’s informational BMI and calorie estimate.

Classic can estimate BMI and a daily calorie target from measurements and choices you provide. These calculations are general informational tools, not medical guidance.

Create an estimate

Open the BMI/profile control in the right sidebar.
Choose metric or imperial units.
Enter your age, height, and weight.
Select the available lifestyle and goal choices that best represent what you want to calculate.
Review the resulting BMI and daily calorie estimate.

Choose the unit system first, then review every input used for the estimate.

Classic displays the resulting daily calorie goal as an informational recommendation.

Use estimates as context, not a diagnosis.

BMI does not measure body composition or determine individual health. The calorie result is not a prescription and cannot guarantee weight change. Speak with an appropriate professional when you need guidance for a medical condition, nutrition plan, or individual health concern.

If the result looks wrong

Confirm the selected unit system and recheck age, height, weight, lifestyle, and goal values. A metric measurement entered while imperial units are selected, or the reverse, can produce an unexpected estimate.
