I have been eating this way to control my diabetes for several years. After going to the Dr. for what I thought was diabetic foot ulcers, I was diagnosed with two invasive malignant melanoma tumors on the bottom of my foot. I first noticed dark spots on my foot about two years prior, about the time I changed my diet. They cut out the tumors and biopsied two lymph nodes in my groin which were clear. The hole that was left in my foot was about 4 X 5 X ½ inch which healed over in a little over three months. I read that cancer cells feed off of sugar, so, with little effort, I could cut my carbs from 50-100 to 25 grams per day. I am convinced that my clean eating prevented it from spreading, and the very low carbs helped me heal so fast.
