What Is a Healthy Weight?
Your weight affects your health. If your weight is above what is
considered a normal weight, you could be more likely to
develop certain diseases or health conditions.
How do you know if you are a healthy weight?
One measure of weight is called BMI, which stands for "Body Mass Index."
BMI is a number, based on your height and weight, which can tell you if
you are a "normal" weight, or if you are underweight, overweight or
obese. In general, a healthy weight for adults is a BMI that is in the
"normal weight" range. Overweight and obesity are both labels for ranges
of weight that is more than what is generally considered healthy for a
given height.
What is your BMI?
To calculate your BMI, divide your weight in pounds by your height in
inches, squared, and multiply by 703.
BMI = weight (lb) / height (in)2 x 703
You could also use a BMI calculator or a BMI chart. Or at your
next doctor’s visit, ask your doctor to tell you your BMI, and
write it down in your chart.
These tools will tell give you a number that is
your BMI.
If you are an adult and your BMI is:
-
18.5 or lower, you are considered "underweight"
-
18.5 to 24.9, you are "normal weight"
-
25 to 29.9, you are "overweight"
-
30 or more, you are "obese"
Note: BMI may overestimate body fat in athletes and
others who have a muscular build. BMI may underestimate
body fat in older persons and others who have lost muscle.
BMI is only one piece of a person's health profile. Talk with your
doctor about other measures and risk factors.
