You should know that fasting heals our body and mind. I do not recommend fasting while on medications. Dr. Furhman never lets his patients fast if they are on medication.
So the diseases start with eating wrong foods, environmental toxins and toxic thoughts. It also takes us a long time to get to a diseased state so expect to take 1.5 times longer to get better.
My recommendation is to do a colon cleanse, kidney cleanse and the Liver Flush (LF). Liver-Flush will be an amazing thing for you. Also start eating nature made plant based raw foods to get all micronutrients needed to heal your body. After all the cleanses stay on raw foods for a month and then you can fast, you will definitely see great benefits from fasting.
