MD's / KFC Cleanse!?

Couldn't a person fast for a day while drinking lots of apple juice, and then go and pig out at McDonald's or KFC on greasy burgers, chicken, and fries with lots of gravy, and expect a cleansing effect? I would do anything to not have to drink that mixture of olive oil, and lemon again, maybe I could stick a tube down my throat to get it down next time! Tweet
