Is there a way to measure the weight of skeletal muscle? I understand body fat and lean body mass can be measured by: skin fold calipers, electrical impedance, table lookup based on formula of weight, age, and height. I have not seen a method to determine skeletal muscle. I asked an endocrinologist and they were not aware of a method.
I suspect subtracting the weight of the skeletal bones, skin tissue and organs from the lean body mass weight could determine weight of skeletal muscle. It seems this number could vary greatly be the person unless perhaps people who handle deceased people have accurate measurements of the above for age, weight, height, etc...
It would be useful to know the weight of skeletal muscle because it could be used to determine body energy expenditure, as lean muscle uses more calories than fat.
