This is a lemonade-based fast prescribed for detoxification and weight loss. I found it when I was looking to detox my body. It was presented to me by a highly regarded holistic nurse, Sandra Duggan, who is one of the co-founders of the Cayce-Reilly School of Massotherapy at the ARE. According to the book she gave me, this is a healthy way to fast because between the lemons and the maple syrup you get all the micronutrients you need to sustain the body. Grade B syrup has higher contents of those macronutrients so use it if you can find it. Also, organic lemons are best. You can leave out the cayenne if you are spice-averse; its role is to help break up toxic deposits within the body. The citrus can do that as well; the cayenne just helps it go faster. It would be well to get a colonic during the time of your fast in order to aid along the detox/weight loss process. I used the fast for 2 days and lost 10 lbs that week (though weight loss was not my goal). Use this fast with spiritual goals in mind and you can achieve great results.
