Free Fat Mass?

Does anyone know what this is?

I have Fat Index: 24.5
Fat Mass: 20.8kg
Free Fat Mass: 64.5kg

Normal Fat Index: 17-24%
Normal Fat Mass 13.2-20.4kg

Now I KNOW I have more than .4kg of fat to lose - does this mean I need to lose most of the free fat mass too?

Well, not being nibby but what is your height and weight....maybe, would that be in the high normal range for you?? What is your BMI?....

"To calculate your body weight in terms of fat and lean body mass, first multiply your total body weight by your body fat percentage. This will give you the weight of your body fat. Now subtract this number from your total body weight, and you will have the weight of your lean body mass.

•total body weight x body fat percentage = weight of body fat
•total body weight - weight of body fat = weight of lean body mass
For example, if your total body weight is 200 pounds, and your body fat percentage is 25%:

•200 x .25 = 50 lb of body fat
•200 - 50 = 150 lb of lean body mass
You can now track the changes in both your body fat and lean body mass, the latter indicating whether or not there is a change in the amount of muscle on your body.

Classification Men Women
Essential Fat 2-5% 10-13%
Athlete 6-13% 14-20%
Fitness 14-17% 21-24%
Average 18-24% 25-31%
Obese 25% and above 32% and above

So its basically saying you need to lose 0.5% more to be at the fitness level.

Um, I KNOW I need to lose more than 0.5kg of fat as I need to lose ~ 71lb to be at a healthy weight though!

Did you possibly do a poor conversion from lbs to kg or enter in the number wrong? Or your height was put in wrong?

The Fat free mass is what your body is that isn't fat - so you can't really lose that without losing bone or muscle or organs...

I think the machine must have got it wrong!
