What Do the Numbers Mean?

Establishing our baseline, the point we will measure back to at the end of the challenge, we utilized the Omron scale to evaluate our current state for BMI, Body and muscle fat percentages, visceral fat and body age.

Below are ideal numbers and source links to where more information can be found. These are just numbers, tools to assist in guiding our course during our journey to becoming more healthy.

BMI
​
If your BMI is less than 18.5, it falls within the underweight range.
•If your BMI is 18.5 to 24.9, it falls within the normal or Healthy Weight range.
•If your BMI is 25.0 to 29.9, it falls within the overweight range.
•If your BMI is 30.0 or higher, it falls within the obese range.

Body Fat Percentage

Body fat percentage is the percentage of your weight that is made up of fat. It consists of both storage
body fat and essential body fat. There are several ways to calculate your body fat percentage, including bioelectrical impedance analysis, skinfold methods and other anthropometric methods, or methods involving the circumference of various body parts. Here's a method to calculate your body fat using only your scale and a calculator.
Women:

• 20-40 yrs old: Underfat: under 21 percent, Healthy: 21-33 percent, Overweight: 33-39 percent, Obese: Over 39 percent
• 41-60 yrs old: Underfat: under 23 percent, Healthy: 23-35 percent, Overweight : 35-40 percent Obese: over 40 percent
• 61-79 yrs old: Underfat: under 24 percent, Healthy: 36-42 percent, Overweight: 36-42 percent, Obese: over 42 percent

Body Muscle Percentage

Ideal for women 28% and 39%

Muscle mass is important in determining a healthy body composition. A person with a higher % of muscle mass finds it easier to move, but needs more energy to do it. Exercise is very important in maintaining a healthy body and the muscle mass % is a useful indicator to control it. The normal muscle mass percentage on the body weight lies between 38% and 54% for men and between 28% and 39% for women depending on age and physical activity level.

Body Age

Body age is based on your resting metabolism. Body age is calculated by using your weight and body fat percentage to produce a guide to judge whether your body age is above or below the average for your actual age. To know your body age is useful to improve your health condition.

Body age varies according to Body composition and resting metabolism, even if your height and weight is the same The figures below shows some examples of body age. The example on the left has a body age of 30, or average body composition for the actual age. The example in the middle has a lower body fat percentage than average and higher resting metabolism, which results in a body age of 25 that is younger than the actual age. The example on the right has a higher body fat percentage than average and lower resting metabolism, which results in a body age of 35 that is older than the actual age.
