I need to lose weight. How do I know what is a healthy weight for me?

The best way to determine your ideal weight is by calculating your Body Mass Index (BMI). BMI is calculated by dividing your weight in kilograms by the square of your height in meters (kg/m2). You can use an online calculator to find out your BMI. A BMI between 18.5 and 24.9 is considered normal, while anything over 25 is considered overweight or obese. Your doctor may also be able to help you calculate your BMI.
