That is true. He IS a chiropractor and for that reason alone I had a great deal of skepticism, especially given the landscape of those making a living off of osteoporosis 'advice.'

However, McCormick's extraordinary knowledge is based on research AND most importantly, was motivated by his own acute osteoporosis. with breaking bones, when he was a world class athlete and could not find satisfactory treatment.

If you take the time to review his book Great Bones, you will find a) he does not take a 'one size fits all' approach and b) he has extensive annotations referencing the source of whatever information he is sharing and discussing. It is impressive.

I understand he is now back to competitive running.
