Well, juice fasting will intensify the detox, but I disagree that fasting is for the strong. Fasting is actually the best thing to do when one is seriously sick. I've been there, and was getting nowhere even with the healthiest foods on earth, not digesting and losing tons of weight. I started vegetable juice fasting and the weight immediatly stabilized. Sure, you have to handle the extremly severe detox symptoms at first, but you can expect a turnaround pretty quickly with fasting. Of course one should be extremly cautious and assist the organs of elimination during the fast, otherwise you're asking for troubles.
