I’ve not read the book you mention but many like it. I’m very pleased to learn you are consulting with your physician before you try any of the “curative” diet suggestions.
During treatment, my problem was consuming calories because chemo really affected my tastebuds. I also wonder at the top level how it is possible to starve cancer without starving the body.
I am unusually sensitive about people who publish the “I have a cure” book because a close friend believed, denied conventional treatment, and died well before his time.
Stay the course.
