BMI (Body Mass Index) is a numerical value that indicates whether your weight is within a healthy range based on your height. It is calculated by dividing your weight in kilograms by your height in meters squared. A BMI below 18.5 is considered underweight, a BMI between 18.5 and 24.9 is considered normal, a BMI between 25 and 29.9 is considered overweight, and a BMI of 30 or higher is considered obese. BMI is a useful tool to assess your weight and determine whether you need to make changes to your lifestyle for a healthier body.
