At the Duke Diet and Fitness Center, our residential clients can choose from three levels of carb intake that happen to be aligned with the Diet Doctor’s levels of liberal low-carb, moderate low-carb and keto low-carb. The alignment is not by chance, however. It’s because we have separately come to the same conclusions after carefully and objectively reviewing the evidence and gathering information from experienced clinicians and patients. The Diet Doctor website is very unique in that regard, and a great resource for our patients!
