It depends on a number of factors

The following four factorst determine your ideal weight:

  • gender
  • height
  • age
  • physical frame

Body Mass Index (BMI)

One way to determine if your body weight is appropriate is to use the Body Mass Index (BMI). It is a formula used by dieticians and doctors to estimate the total body fat based on your height and weight. The higher the BMI, the more body fat you have.

You can calculate this out yourself by doing the following:


BMI = (Weight * 703) / (Height * Height)

So for example if you weigh 100 pounds and are 5' 4" (64 inches) then the calculation goes as follows:


BMI = 100 * 703 / (64 * 64)
BMI = 70300/4096
BMI = 17.1

BMI Score

  • Obese - BMI 30+
  • Overweight - BMI 25-30
  • Normal - 18.5-24.9
  • Underweight - less than 18.5

The higher your BMI score, the more body fat you have and prone to have diabetes, heart ailments, and physical health problems.
