What's Your BMI?


Body Mass Index (BMI)

According to the CDC, Body Mass Index (BMI) provides a reliable indicator of body fatness for most people, and is used to screen for weight categories that may lead to health problems.1

Overweight is defined as a BMI of 25 to 29.9 while obesity is defined as a BMI of 30 or above. The recommended upper limit of body fat as a percentage of body mass is 25.0%.

BMI   WEIGHT STATUS  
Below 18.5 Underweight
18.5–-24.9 Normal
25.0–29.9 Overweight
30.0 and Above Obese
Calculate Your BMI
To calculate BMI, you can divide your weight by your height, squared.
But there's an easier way! Just use the BMI calculator:
  1. Select your height in feet / inches
  2. Enter your weight in pounds
  3. Click on the "equals" button to see your Body Mass Index
Limitations

The BMI calculator does have limitations. First, it may overestimate body fat in athletes and those people with a muscular build. Second, it may underestimate body fat in older persons and others who have lost muscle mass. Why the difference? BMI is calculated using weight and height only. It does not measure body composition or body fat. The calculator should therefore only be used as a general guideline to monitor trends, not as a diagnosis of your health status. Use the BMI calculator as a readily available tool to mark where you are now, then to track your progress. Schedule an appointment with your health care provider to determine your true weight status, your associated health risks, and what your target BMI range should be.

Overweight and Obesity: The Health of The Nation

Overweight and obesity contribute to the cardiovascular disease burden of our County and our Nation. Heart disease remains the number one killer of Americans. Obesity and overweight are known to influence the impact of this disease on the population. Obesity is also an independent risk factor for coronary heart disease (CHD). In some studies even mild to moderate overweight is associated with a substantial elevation in CHD risk.

Over the past 2 decades, the number of cases of obesity alone has increased more than 50 percent. According to data from the 1988-1994 Third National Health and Nutrition Examination Survey (NHANES III), overweight and obesity affect more than one-half of the U.S. adult population (59.4 percent of men and 50.7 percent of women).
