Do read ARTHUR AGATSTON, M.D.'s book "THE SOUTH BEACH DIET" as he talks about Insulin Resistance and pre-diabetes and why with hormone imbalance it is difficult to lose the weight. I've gotten so much from reading his book. He is a Cardiologist and Professor at the U. of Miami Medical School. He didn't start out to write a "diet" book, but developed his program to help his patients.
I got it at the library and read it for free. 2750 days ago
