How much muscle in LBM

[dahamn]

I'm 183 lbs with 15.5% bf, thats around 28.3 lbs of fat. Of the 155 lbs left how much is muscle and how much is water and other stuff?

impossible to tell. There is no way to separate what part of the LBM is muscle, bone, blood, water, etc... at least, not with you still alive... once you are dead, there are a number of things the crafty docs can do to find out...

Does anyone know if muscle has a greater mass than bone, or vice versa?

Probably a small portion, most of our body is water. Are you looking for dry protein mass or muscles (everything in a muscle cell). I believe muscles are 70% water. Hard to calculate that...not sure how useful it is either. But I remember being quite shocked to see the dry protein mass a few years ago.

How do you figure out how many lbs of that is fat?

Multiply total weight by bodyfat percentage, that will tell you the weight of fat.

weight = 183
bf % 15.5%

183 X .155 = 28.365 lbs of bf

wrong bro.

research DEXA. if you're in the LA area I can tell you where to get it for 70 bucks.

OK, I stand partially corrected, since DEXA at this stage, is capable of determining the body composition in 3 vectors: Body Fat, Bone and LBM. A new method for adding Protein as a 4th component has been suggested. (that would be interesting indeed).

Note that water weight CANNOT be separated yet.
