Which detox should I choose? Help.

I have hypertension and many lbs overweight. I am going to do Kenneth Baum's metabolize diet, but before I do I want to detox first. I would like to fast for a few days but I hear that fasting slows the metabolic rate and being overweight I do not want that. If I went on a mono diet of say like oranges for a few weeks will that spike my blood Sugar levels? Should I only do then dark greens? I already have powdered E3 Live that I can do with it. Any suggestions? Tweet
