I actually borrowed elements of Dr. Clark's liver cleanse and mixed it with another (supposedly thoroughly legit) approach. I did take oil and grapefruit juice, according to the stipulations put forth both by Dr. Clark and by the apple juice fast method. I recognize that fasting may not be necessary, but it didn't hurt and that was one option put forth and I decided it might work for me, given my health history (bloating issues in particular). So I was trying to adapt the method to my own needs while retaining that which seemed to be the essential elements of the cleanse. I followed every recommendation and read about what each element was supposed to accomplish, so I wasn't squelching anywhere. It simply didn't produce the results that I have read about. I'm willing to try it again, in the interest of Science and my health, doing a Colon Cleanse first and seeing what 'comes to pass'. I'm not a complete skeptic, but I'm not into mere faith healing either. I was just looking for some validation of my personal experience and some possible recommendations.
