Q:

What are typical values for bone mass in humans?

I wonder what are typical bone mass values for adult males and females? And do they change significantly with workout and diet?

I wonder what are typical bone mass values for adult males and females?

This seems hard to find. The only value I could find is on Bionumbers at it says that vertebrates compact bones have a mean density of 2 mg/cm$^3$ [1]. However in medical practice two scores are used to indicate the ratio between tested bone density and ideal bone density [2, 3] and absolute values are uncommon.

And do they change significantly with workout and diet?

Bone mass is mainly influenced by genetic factors. Only up to 25 % may be influenced by environmental factors such as diet and exercise [4].
Among the medical conditions that influence bone mass, osteoporosis is the most frequent especially in women. Other conditions are: hyperparathyroidism, glucocorticoid therapy, other bone abnormalities and fractures [2].
