⚖️ BMI Calculator

BMI is a useful screening tool but not a diagnostic measure. It doesn't account for age, sex, muscle mass, bone density, or fat distribution. A person with high muscle mass may have a "overweight" BMI while being very fit. Always consult a doctor for a complete health assessment.

BMI Prime is your BMI divided by the upper threshold of normal BMI (25). A BMI Prime of 1.0 means you're at exactly the upper limit of normal. Values below 1.0 are normal weight or below; values above 1.0 indicate overweight or obese. It allows easy comparison regardless of the specific BMI value.

The WHO uses the same BMI categories for both men and women (18.5–24.9 for normal weight). However, women naturally have higher body fat percentages than men at the same BMI. Some health organizations suggest women may be healthy at slightly lower BMI values than men.

Sustainable approaches include: combining moderate caloric deficit with regular physical activity (150+ min/week cardio + strength training), focusing on nutrient-dense whole foods, adequate protein intake (1.2–1.6g per kg body weight), sufficient sleep (7-9 hours), and managing stress. Avoid extreme diets — gradual changes are more sustainable.
