What is BMI?

BMI is a measure of body fat based on height and weight. It is calculated using a simple formula that takes into account both your weight and your height. This results in a single number, which indicates whether your weight is healthy for your height.

How is BMI Calculated?

The formula used to calculate BMI is fairly simple: your weight (in kilograms) divided by your height (in metres) squared. This equation results in a single number – your BMI – that corresponds with a range of numbers which correspond with different levels of health.

What Does BMI Reveal About Your Health?

BMI is an important indicator of overall health. It is used to assess whether you are at a healthy weight for your height, as well as to monitor changes in weight over time. A higher BMI is associated with higher risk for a range of health conditions, ranging from diabetes to heart disease. A BMI of 18.5 to 24.9 is considered healthy, while anything above 25 is considered overweight.

What is the difference between BMI and Body Fat Percentage?

BMI (body mass index) is a measure of a person’s weight relative to their height and can be used to determine if a person is over- or underweight. Body fat percentage is simply the ratio of a person’s fat mass to their total body mass; it is a much more accurate measure of overall body fat, but does not take into account body composition or other factors.
