BMI is calculated using the following formula:
$$BMI\;=\;\frac{Weight\;(Kg)}{Height\;{(M)}^2}$$
For measurements in pounds and inches, the formula becomes:
$$BMI\;=\;\frac{Weight\;(Lb)}{Height\;{(in)}^2}\;\times\;703$$
BMI Categories:
BMI categories are generally classified into the following ranges:
Underweight: BMI Less Than 18.5
Normal Weight: BMI Between 18.5 And 24.9
Overweight: BMI Between 25 And 29.9
Obese Class I: BMI Between 30 And 34.9
Obese Class II: BMI Between 35 And 39.9
Obese Class III: BMI 40 Or Greater
Interpretation

Athletes and individuals with high muscle mass may have a higher BMI without excess body fat. Therefore, BMI should be interpreted cautiously and considered alongside other health indicators.
Health Implications
Underweight: Associated with potential nutritional deficiencies and weakened immune system.
Normal Weight: Generally associated with lower health risks.
Overweight and Obesity: Linked to increased risk of various health conditions, including cardiovascular diseases, diabetes, and certain cancers.
Limitations of BMI
Does not differentiate between fat and lean body mass.
Does not account for the distribution of fat in the body.
It might incorrectly categorize individuals with high muscle mass as overweight or obese.
Importance in Public Health
BMI is widely used in public health initiatives to assess trends in weight status within populations. It aids in identifying potential health risks at the population level and shaping public health policies.
Monitoring and Lifestyle Modifications
Regular monitoring of BMI is valuable for assessing changes in weight status over time. Individuals outside the normal range can make lifestyle modifications, including adjustments to diet and exercise, to improve their overall health.
Consultation with Healthcare Professionals
For a comprehensive assessment of an individual’s health, it is advisable to consult healthcare professionals who can consider BMI alongside other factors such as medical history, body composition, and waist circumference.
