    Question *Actual* density of muscle vs. fat (without water)?

    I've been looking for specific values of muscle vs. fat density. The best I've come across is this:

    http://www.nutracheck.co.uk/Library/...-muscle_1.html

    In summary, research suggests that muscle density is 1.06 g/ml and fat density is (about) 0.9 g/ml. Thus, one litre of muscle would weigh 1.06 kg and one litre of fat would weigh 0.9 kg. In other words, muscle is about 18% denser than fat.
    However, unless I misread this doesn't take into account that muscle is largely comprised of water, whereas fat isn't.

    WRT to fat, the best I could find is that about 15% of 1lb of body fat is water, which is why you need to burn 3500 calories instead of 4086 (454g x 9cal/g) to lose 1lb of body fat.

    Does anyone know what % of 1lb of muscle is water vs. tissue and therefore the actual density ratio of muscle:fat without water?

    I'm just wondering why you need to know this? Just curious? Or is there some other reason?

    Curious & other reasons. So far the number I'm getting is 72% water for muscle.
