The person above is failing to consider that for a valid
comparison, all other parameters should be the same: 
same total calcium, same total phosphorus.

I bet that is not so in whatever study he is looking at.

In any cases, the demographic group with the highest
bone mineral density -- namely, weightlifters -- also
is one with among the highest protein intakes. So it
certainly is not true that high protein diets *will*
cause calcium loss.

This would be apparent to anyone capable of even
a modicum of thought.
