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

You can use the Body Mass Index (BMI) calculator to calculate your BMI and determine if you are within a healthy range of weights. The BMI is a measure of body fat based on height and weight, and it is used as an indicator of health risks. A BMI between 18.5 and 24.9 is considered normal, while a BMI greater than or equal to 25 is considered overweight.
