LBM is fairly easy to calculate once you have weighed yourself and figured your body fat percentage. You just calculate your body fat in pounds and subtract that from your bodyweight.

You can use the equations below or let the Guide's calculator calculate your body fat percentage and lean body mass.

Body Fat in lbs. =
(Total Bodyweight) x (Body Fat Percentage (in decimal form))

Lean Body Mass =
Total Bodyweight - Body Fat in lbs.

So someone who weighs 173 pounds with a body fat percentage of 17.5% would calculate as follows:

(173)x(.175) =

30.3 lbs. of body fat

173 - 30.3 =

142.7 LBM



Work out how many calories you need to consume per day? (RMR)

To work out how many calories your body needs per day you’ll first need to work out your body fat percentage and lean body mass

Resting metabolic rate (RMR) how many calories you need to maintain basic life functions (or how many calories I can eat without putting any weight on)

RMR = lean body mass (pounds) divided by 2.205 x 30.4

The accuracy of your LBM number is dependent on the accuracy of your inputs - your weight and your body fat percentage. As body fat percentages can be all over the map based on the methods used, your LBM as an accurate gauge of your fitness level should be taken with a grain of salt. Use the mirror to make any major judgements about your body, use lean body mass as a progress report for your training program.



BMI calculation

One way to verify the number is to do the math yourself, plugging your height and weight into the formula for BMI:

Weight in pounds X 704.5; divided by [height in inches X height in inches].

Example: person weighing 140 pounds, whose height is 65 inches;

140 X 704.5 = 98,630, which, divided by 65 X 65, comes to 23.3.

Once you have worked out how many calories you need you can then print off our seven day food diary were you can keep a track of what you eat and how many calories you are eating a day. (Go to Keeping a Food Diary) click here
