What is BMI?

BMI (Body Mass Index) is an indicator of one’s health status that is widely used to see if a person’s weight is adequate concerning their height.
The Body Mass Index Formula takes into account:
Weight in kilograms (kg)
Height in meters (m)
This allows determining what category the individual belongs to regarding their body weight, which may include:
Underweight
Normal
Overweight
Obesity
BMI calculations are frequently used by medical professionals in assessing someone’s health condition.
BMI Formula for Women
The standard BMI formula is:BMI=Height2 (m2)Weight (kg)
Example:
- Weight = 62 kg
- Height = 1.65 m
BMI = 62 ÷ (1.65 × 1.65) = 22.8
A BMI between 18.5 and 24.9 is generally considered healthy for adult women.

Women go through many changes in their bodies as they get older. The following elements could affect BMI calculations:
Hormone changes
Pregnancy
Menopause
Reduction in muscle mass
Slower metabolism rate
