Is it safe? How long and how to do it the safe way?
I have done it and had good results as far as increased energy, glowing skin, and better mental state. I always recommend doing a juicing (or even blending if you do not have a juicer) cleanse or raw cleanse over the master cleanse because of all the real nutrients you get from the veggies and fruit. Be sure to eat well at least a couple of days before and after. Try to eat raw before the cleanse. After the cleanse eat only broth for a couple of days and then introduce raw diet for a couple more days. If this is your first cleanse 10 days at most is recommended. One more thing. Depending on where you live. It's important to do cleanses during warm weather instead of during winter weather. Eating increases body temperature. I also worked out during cleanse, just only at 50% of my capacity and felt fine. Good luck!
