Because to keep your bones healthy, you need to bare weight on them. Since you are essentially weightless, prolonged time in space would cause the bone matrix to start to break down and become "brittle" over time.

Since there is no gravity in space one's bones would not have any weight on them and would become lazy. Just like someone who watches too much TV and wouldn't be able to move too much.
