Enter height and weight to calculate BMI
BMI (Body Mass Index) is a body composition index calculated from height and weight. It is widely used as an indicator of obesity recommended by the World Health Organization (WHO).
BMI (Body Mass Index) is a body composition index calculated by dividing weight (kg) by the square of height (m). It is widely used internationally to assess obesity and underweight conditions.
Standard weight is calculated as 'height (m) squared × 22'. A BMI of 22 is considered statistically optimal for the lowest risk of disease.
BMI cannot distinguish between muscle mass and body fat, so it may not accurately reflect the physical condition of athletes or elderly individuals. It should be used as a general guideline.
Research suggests that the optimal BMI range may vary with age. Older adults may benefit from a slightly higher BMI to help prevent frailty and sarcopenia.
