70 Calculating Lean Body Mass Now that you know your body-fat percentage, you can calculate your lean-body percentage. This will eventually show you how many pounds of muscle were added to your body, after completing the program. For Example: Before the program, Joe weighs 200 pounds (90.7 kg) and measures 30% fat, which amounts to 60 pounds (27.2 kg). Thus, his lean-body mass is 70%, or 140 pounds (63.5 kg). After the program, Joe weighs 180 pounds (81.6 kg) and is 20% fat, which equals 36 pounds (16.3 kg). His­­ lean-body mass is 80%, or 144 pounds (65.3 kg). Simple calculations allow us to find the amount of fat Joe lost, and the amount of muscle Joe gained. Before fat weight (60 pounds), minus after fat weight (36 pounds) equals 24 pounds (10.8 kg) of fat lost. After lean-mass weight (144 pounds) minus before lean-mass weight (140 pounds) equals 4 pounds (1.8 kg) of muscle gained.

Now that you know your body-fat percentage, you can calculate your lean-body percentage. This will eventually show
you how many pounds of muscle were added to your body, after completing the program.
For Example:
Before the program, Joe weighs 200 pounds (90.7 kg) and measures 30% fat, which amounts to 60 pounds (27.2 kg).
Thus, his lean-body mass is 70%, or 140 pounds (63.5 kg).
After the program, Joe weighs 180 pounds (81.6 kg) and is 20% fat, which equals 36 pounds (16.3 kg). His lean-body
mass is 80%, or 144 pounds (65.3 kg).
Simple calculations allow us to find the amount of fat Joe lost, and the amount of muscle Joe gained. Before fat weight
(60 pounds), minus after fat weight (36 pounds) equals 24 pounds (10.8 kg) of fat lost. After lean-mass weight (144
pounds) minus before lean-mass weight (140 pounds) equals 4 pounds (1.8 kg) of muscle gained.
