How can I tell if I weigh too much?

Gaining a few pounds during the year may not seem like a big deal. But these pounds can add up over time. How can you tell if your weight could increase your chances of developing health problems? Knowing two numbers may help you understand your risk: your body mass index (BMI) score  and your waist size in inches.

Body Mass Index

The BMI is one way to tell whether you are at a normal weight, are overweight, or have obesity. It measures your weight in relation to your height and provides a score to help place you in a category:

• normal weight: BMI of 18.5 to 24.9
• overweight: BMI of 25 to 29.9
• obesity: BMI of 30 or higher
