How to read it

4

A quick overview of how the result is formed and how to apply it in practice.

BMI is calculated with the formula: weight / height?.
It is a simple screening metric, but it does not show body composition.
With higher muscle mass, BMI can be elevated without excess body fat.
That is why BMI works best together with waist size, body fat percentage, and context.

Tips

5

Small practical steps to help you apply the result day to day.

Compare BMI over time rather than focusing on one reading.
Measure body weight in similar conditions, ideally in the morning.
Use BMI as a broad reference, not as the only health metric.
If you train regularly, compare BMI with body fat percentage as well.
Avoid conclusions from the number alone without body composition context.

FAQ

4

Short answers to common questions about calculations and interpretation.

What does BMI show?

BMI shows the relationship between height and weight and places body weight into a broad category.

Is BMI an accurate body fat measure?

No. BMI does not distinguish between muscle, fat, and water, so it works best together with other metrics.

Why can athletes have a high BMI?

Because BMI only uses height and weight. More muscle can raise BMI without excess body fat.

Should I lose weight only because of BMI?

Not by itself. It is better to consider waist size, body fat, labs, and overall health context.

BMI is a general indicator, not a medical diagnosis.
