The BMI (Body Mass Index) is a tool to find out if your weight is healthy. It is calculated by taking the weight in kg divided by the height in meters squared. You can use this calculator from the NHS to find out your BMI and if your weight is within a healthy range. If your BMI is below 18.5, you are considered underweight, a BMI between 18 – 24.9 is considered normal or healthy weight, between 25 – 29 it is overweight, and a BMI above 30 is considered obese. The BMI is not necessarily applicable for people who have a lot of muscles (as muscle is heavier than fat), women who are pregnant, as well as children and teens.
