G'day Larry,

A diet high in protein will only damage kidneys if there is an existing problem. If your kidney function is normal, all the protein in the world cannot cause them any harm.

You could try challenging your doctor to show you some studies which show people with normal kidney function developing problems as a result of eating more protein.
There are no such studies! Dr Atkins himself has publicly called for anyone with such information to come forward and to date, no one ever has. There is plenty of opinion stating that low carb causes all sorts of harm, but when it comes to the nitty gritty, the proof just isn't there.

And you could also try reassuring your doctor that low carb eating plans such as Atkins provide adequate protein, rather than "high."

Cheers.
