Defining A Healthy Body Mass Index

Body mass index (BMI) is a measure of body fat based on height and weight that applies to adults. Body fat percentage evidence suggests that men should have a BMI that is approximately 2.3 kg/m² higher than women.

 BMI Categories for women:

  • Underweight = <18.5
  • Normal weight = 18.5-24.9
  • Overweight = 25-29.9
  • Obesity = BMI of 30 or greater

Disclaimer: Keep in mind that BMI is a screening tool; it is not used to diagnose any medical conditions, but instead, is used as one measure to assess a woman’s weight and her risk for developing certain medical conditions.

To determine if excess weight is a health risk, a healthcare provider will perform further assessments. According to recent guidelines, assessment of weight involves using three key measures:

  1. BMI
  2. Waist Circumference
  3. Risk factor for diseases and conditions associated with obesity

Your Ideal Weight

The most accurate assessment of your ideal weight takes into account the composition of your body – how much of your weight is lean body mass (muscle and bone) and how much is body fat . For optimum health, body fat should be no more than 20% of total body weight for men and 30% for women.

Body Frame Sizes

In order to refine and define theoretical weights, researchers added frame size as a factor.
The sizes are categorized into three categories: Small frame, medium frame and large frame.
The reason for this is that obviously bone structures vary in size and density from person to person. Equally obviously men and women have different structures. Bone mass and muscle mass all play a part in determining your optimal weight. Large boned people. There are two simple methods of determining frame size:

  1. Measuring the circumference of your wrist. This is by far the most straight forward
  2. Measuring the breadth of your elbow. This is a little more complex but provides a greater results range for the purposes of accuracy.

To do this you need to:

  1. Stand up.
  2. Extend your arm forward so that it is horizontal and parallel to the ground.
  3. Turn your hand so your palm is uppermost.
  4. Bend your elbow so your forearm is at 90º to the ground.
  5. Use the forefinger and thumb of your other hand to locate the narrow part of your elbow joint.
  6. Use your same forefinger and thumb as a guage to determine your elbow breadth by measuring the gap between them with with a ruler or tape measure.
  7. Compare the value with the tables on the right.
