What is BMI?
Body Mass Index (BMI) is a widely used measure to determine if your weight is healthy in proportion to your height. It's a simple screening tool that helps categorize individuals into weight groups that might lead to health problems. It's calculated based on your weight and height, regardless of your gender.
However, it's important to remember that BMI is a general indicator and not a diagnostic tool. It does not account for factors like muscle mass, body composition, or bone density. For a complete health assessment, it's always best to consult with a healthcare professional.

Frequently Asked Questions (FAQ)
How is BMI calculated?
The calculation depends on the units used:
- Metric Units: BMI = weight (kg) / [height (m)]²
- Imperial Units: BMI = [weight (lbs) / [height (in)]²] x 703
Is BMI interpreted the same for men and women?
Yes, the BMI calculation and the standard weight status categories are the same for both men and women of all body types and ages (for adults). However, men and women can have different body compositions, with women typically having more body fat than men for the same BMI.
What are the limitations of BMI?
BMI is a useful screening tool, but it has its limits. It can be misleading for:
- Athletes and bodybuilders: Their high muscle mass can result in a high BMI, even with low body fat.
- Older adults: They often have less muscle mass, so a "normal" BMI might still indicate excess body fat.
- Pregnant women: BMI is not applicable during pregnancy.
