Can Diet Get My A1C Under 5.7?

Q:  Dear Dr. Trapp,

I have been pre-diabetic for about 3 years. My A1C has been 6.1, two years in a row now. Using diet, what could be my chances of getting it under 5.7?  I am planning to eat a strict WFPB diet for 6 months, and then re-test.  

Sincerely,  Maryann

Dear Maryann,

It is a great idea to use the no oil WFPB dietary approach (like we advocate here at PBNSG), to help lower your A1c. I have had many patients do this successfully, and research supports the effectiveness of this approach.  For a useful resource, check out - providing free meal plans, which are all vegan and oil free.  Also see the 18-minute TEDx Talk with Dr. Barnard at

Wishing you good health,

Dr. Caroline Trapp, DNP, CDE
