Calculating Your Desired Body Fat Percentage

For many of us we are not at our ideal body weight and we would like to change that. But how? And what weight should you aim for to be in the body weight category that you prefer to be in?

Here is a picture description of what each body fat percentage looks like

>>First off find out what your Body Mass Index (BMI) is:

How to calculate: Body weight in lbs/ (height in cm) Squared = result. 
                             Result x 703= Final BMI

Example: 140 lbs/ 65(2)= .033136
                 .033136 x 703 = 23.29%


>>Secondly, find your body fat percentile and see where it falls on this chart:

BMI (kg/m2) = weight in kilograms/height in meter2

When you find your current body fat then figure out what percent body fat would be ideal for you. 

>>Lastly complete the formula

Complete this formula for the desired body fat percentage: 
Desired Body Weight (DBW)
Desired Body Fat (DBF)
Lean Body Weight (LBW)

DBW = LBW / (1-DBF)

Step 1: 100% - Fat% = Lean Body%
Step 2: Body Weight x Lean Body % = LBW
Step 3: 100% - Desired Fat% = Desired Lean%
Step 4: LBW / Desired Lean% = DBW

For example if you were 215 lbs and your current body fat % is 25%, but your desired body fat is 20% it should look like this:

Step 1: 100% - 25% = 75%
Step 2: 215 x 75% = 161.25 LBW
Step 3: 100% - 20% = 80%
Step 4: 161.25 lb / 80% = 201.5 lb
