Frequently asked questions

What is BMI?

Body Mass Index (BMI) is a numerical value calculated from your weight and height. It is used as a screening tool to categorize individuals into underweight, normal weight, overweight, and obese ranges.

What is a healthy BMI range?

A BMI between 18.5 and 24.9 is generally considered normal weight. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese. These ranges may vary by ethnicity and age.

Is my data stored or sent to a server?

Calculations stay in your browser. Analytics may record page and interaction events, but the masked calculator prevents entered health values from being recorded.

What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day, including your basal metabolic rate (BMR) plus calories burned through physical activity.
