This is dusty old stuff. From 2001, before all the new low-carb studies hit the journals.

It's really a propaganda piece, training physicians how to bash the diet.

Most of the 'claims' have been long refuted.

I wouldn't worry about it.

This piece -- incidentally, from the same journal, I believe -- negates most of it, one year later.
