muscle loss vs. lean mass loss

When dieting and losing some lean mass while losing fat, where is the loss of lean mass likely to come from? I think the body naturally holds less fluid, and obviously some muscle is lost. Sometimes bone loss may occur, but hopefully with a high calcium intake and a sane diet this doesn't occur too much. That leaves connective tissue and internal organs.

What ratio of muscle to other lean tissue should someone on a diet expect to lose? And how can one minimize bone loss (other than calcium and vit D)? What organs and connective tissue does the body seem to lose the most of, if there is anything in specific? And by what mechanism is the non-muscle lean mass predominantly lost? Aminos? Fatty acids? Minerals?
 
There will prolly never be an answer to those questions as they relate to bodybuilders. First of all it's very individual. A sodium/carb sensitive individual can appear to lose a great deal of LBM just by dropping carbs or salt. A person who has a relatively high starting %bf should be able to gain LBM, or at least lose fat while maintaining LBM. Additionally, the use of AAS will make a big difference. Older folks carry more visceral fat so that they may have very thin skinfolds (Look ripped) but have a relatively high %bf as measured by DXA. Then there's gender differences......'natural' females are at greater risk of bone loss when down to low bodyfat than natty males, and natty women also lose a higher percent of muscle to fat. Then again females tend to retain more fluid which messes with LBM determination.

Too complicated to give a sensible answer!
