My answer to you is still that you can do the BPs at >anytime< while eating regular. You can continue detoxing and loosening mucous with a mostly raw diet, veggie juices and drinking half your bodyweight in ounces of H2O. The BPs will do it's job still after you let the Master-Cleanse work it's mojo without adding anything that will interfere with it's cleansing and healing action.
Part of giving the digestive system a break so the body will use that energy to help cleanse and heal involves the peristalsis action in your intestines. When you add the BPs with all that fiber it will stimulate the persitaltic action in your intestines to move that fiber out so your body will be having to use energy that would otherwise be used for cleasning and healing.
The guy that came up with the so called Ultimate Cleasne didn't even consider or even know about how the Betonite works and that it would absorb any nutrients taken along with it. The reason the UC has even become known is related to the mainstrean ,commercially programed mindset of trying to find that "magic pill" that will do everything. Nothing in nature works that way. >No-Thing<
All or most natural healing and cleansing methods work gradually and take time and no one thing is gonna do it all. I truly believe that the mindset of "getting the most in the shortest time" is right there with the "more is better" cliche and is just not compatible with the gradual healing methods of natural healing/cleansing. You're not gonna clean out a "lifetimes worth" of toxins by doing something for a week or 2 no matter how many thing you mix together. It's just not gonna happen. It will take time and the best and most lasting changes will be gradual.
