Food does not leech calcium from the bones. High protein foods improve calcium absorption and increase calcium in your urine as a side-effect. No bone lost there.
Can't find the study, but they made people eat irradiated calcium, and those with higher protein just peed out the irradiated calcium. Bones stay intact.
