Tips for Interpreting BMI Results

While BMI is useful, it should be interpreted carefully.

Consider Overall Health

Monitor BMI changes over time rather than focusing on a single result.

Combine with Healthy Habits

Regular exercise, proper nutrition, and sufficient sleep are equally important.

Consult Professionals When Needed

Healthcare providers can offer personalized guidance based on your complete health profile.

Use BMI as a Starting Point

BMI provides a general assessment but should be combined with other health indicators for a complete picture.

Limitations of BMI

Although BMI is widely used, it has some limitations.

For example:

• It does not measure body fat percentage.
• It cannot distinguish between muscle and fat.
• Athletes may have higher BMI values despite excellent health.

Because of these factors, BMI should be viewed as a screening tool rather than a definitive diagnosis.
