Your weight: How do you compare?

There are many ways to assess your weight status, to know if you are you normal weight, underweight, or overweight. None of the methods are perfect so do a few to get an idea of your weight status.

It is important to do this because studies show that people do not rate their weight accurately.



BMI 
BMI or Body Mass Index is a number based on your height and weight. The number is then compared to a scale to see if you are underweight, normal weight, overweight, or obese. This is a great tool, however it is not appropriate for serious athletes, because they usually come out as overweight when they are not. It is also not appropriate for the very elderly.

The formula is:
BMI = (Weight in pounds/ (height in inches x height in inches)) x 703

Categories:

  • Underweight = <18.5
  • Normal Weight = 18.5-24.9 
  • Overweight = 25-29.9 
  • Obese = >30 


Here is an online calculator that is great and easy to use:

Waist to Hip ratio (WHR)
Waist to hip ratio helps assess your overall health risk. You are at more risk for chronic diseases such as heart disease and diabetes if you carry your weight around stomach and opposed to your hips, where is it less of a concern for your health.

Measure your hips at the widest point and your waist at the belly button point.

waist to hip ratio = waist measurement/ hip measurement

Categories:

  • <.95 for men or <.80 for women = low health risk, optimal range 
  • .96-1 for men or .81-.85 for women = moderate health risk 
  • 1.0+ for men or .85+ for women = high risk

Ideal Body Weight (IBW)

Ideal body weight is a rough estimate of what your weight should be ideally. Some people have never been at this weight, so this is only a guide. You can add or subtract 10% for large and small body frame.

Women: 100 pounds for the first 5 feet then 5 pounds for each additional inch. +/- 10%

ex. 5'6 is 100 + 5x6 = 130 pounds

Men: 106 pounds for the first 4 feet then 6 pounds for each additional inch.  +/- 10%

Hope this helps!
Now that your know where you scale you can work towards a healthy reasonable weight.
