The Science of Fasting

I am combing this with about 800 to 1000 calories a day cardio. I would imagine that the weight will come off faster even than I am shooting for since I can lose a couple a week with the cardio and no diet changes. But weight loss is not the primary reason I want to do it. Once I lose about 14 I will have to address how to "maintain" and not yoyo. This is a much harder idea for me than weight loss.
