Ok this question says, katie is a 32 year old female who is seeking your assistance to improve her body composition and fitness.
00:08
Katie would like to return to her college composition of 24 % of body fat.
00:13
She is currently 64 inches, 157 pounds and 30 % body fat.
00:19
What would katie's target body weight in pounds be if she desired to return to her college body fat percentage? so to determine katie's target body weight we first need to calculate her current lean body mass and current body fat mass.
00:35
Katie's current body fat mass can be calculated as follows.
00:39
You have that a body fat mass is equal to total body weight that in this case is 157 pounds multiplied by the body fat percentage that is equal to 30 % that is the same as 0 .3.
00:56
So if you multiply this you are going to get 47 .1 pounds.
01:02
So this is the body fat mass of total body fat mass.
01:09
Now to determine katie's current lean body mass we can subtract her current body fat mass from her total body weight.
01:18
It means the lean body mass is going to be equal to 157 pounds minus the body fat mass that is 47 .1 pounds and this is going to be equal to 109 .9 pounds.
