BMI is a simple screening tool used to estimate a person’s body fat based on their height and weight. It is widely used by healthcare professionals to identify potential weight issues in adults.
The BMI is calculated using the formula: $$BMI = \frac{\text{weight}}{\text{height}^2}$$
While BMI is a useful, quick measure, it should not be the sole basis for determining a person's health status, as it does not account for muscle mass, bone density, or overall body composition.
No. BMI can overestimate body fat in athletes and those with a muscular build, and it may underestimate body fat in older persons and others who have lost muscle mass. It is not suitable for pregnant women or children.
A BMI in the "Normal" range (18.5–24.9) indicates that your weight is in a healthy proportion to your height for the majority of adults. However, health should always be assessed by a doctor.
You can use the formula: Weight in kilograms divided by the square of height in meters, or $\text{(Weight in pounds} / \text{Height in inches}^2) \times 703$ for imperial units.
