Question 1

How is BMI calculated?

Accepted Answer

BMI is calculated by dividing your weight in kilograms by the square of your height in metres (kg/m²). For imperial units, the formula is (weight in lbs × 703) ÷ (height in inches)².

Question 2

What is a healthy BMI range?

Accepted Answer

According to the WHO, a BMI between 18.5 and 24.9 is considered healthy for most adults. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese.

Question 3

Is BMI accurate for everyone?

Accepted Answer

BMI is a useful screening tool but does not directly measure body fat. Athletes may have a high BMI due to muscle mass, and older adults may have a normal BMI despite excess body fat. Use it as a starting guide alongside other health indicators.

Question 4

How many steps a day should I walk to reach a healthy BMI?

Accepted Answer

Research suggests that walking 7,000–10,000 steps per day supports healthy weight management. Our BMI calculator provides a personalised step recommendation based on your current BMI and age.
