I've actually been eating this way since I was told I was pre diabetic. (I am no longer) Someone gave me a half moon cookie today, my favorite and I had to eat it. However I have pretty much stayed away from sugar and processed foods, but you have to get them out of your house. Certain vegetables add enough sweetness to a diet. I often eat carob chips with a teaspoon of almond butter. (They are sweetened by nature). A sprinkle of stevia on my salads. I was using agave but have heard it isn't that good for you either.

All that white stuff turns to sugar. Cravings come and go and I won't beat my self up if I cheat, but as your body gets used to a better diet when you cheat you feel sick. So just cheat a little.
