I tried michael B's protocol for 2 days and then started eating potatoes...Felt amazing. Okinawa is a plan. Greens fasting will clean you out for a day or 2 but is not something to feed your body and give you energy. Greens, yucca, squash, veggies, cooked plantains. Go on a very low fat and low Sugar diet, low protein too and you will be in good shape. What youre mentioning is a fast.
