[BFL] fat lost and muscle gained

[Fuzzbear]

I've looked at some results and I was wondering how you calculate the fat lost and the muscle gained.
Thank you!

Liz, what you need to have are some measurements on hand at the beginning. You take the measurements and coupled with your weight and a formula you get your Lean Body Mass (LBM) and your Fat Mass. LBM is what you weigh minus your fat. By comparing these numbers every few weeks you can determine now much fat you lost and how much muscle you gained - often there will be little or no scale change yet you will have replaced fat with muscle.

You can determine LBM and %BF here:

Happy calculating!

Thanks again. I have measurements from Sunday as official #'s
I will post these from home tonight on to my journal.
I realized I am a big ol girl! :o
I had bf% done on Feb 6 b4 body for life so that's the only # I have it was a whopping 48.5. It was done with this machine laser thing they stuck on my arm and it determines water content and all taht.


by the way what is an ideal goal for bf loss in a 12 week period. I was going to go for 10-15% goal but I really don't know what is 'normal' ?

For your first challenge 10% isn't uncommon and it's a good goal. If you can, I would go back to where you were originally tested after your 12 weeks are up and have them redo the test.
