Phase 1 gradually reduces the calories you take in while keeping the bulk, then reduces the bulk in days 5-7. You are resting your organs from heavy digestion and detoxing the colon. Your caloric intake dips down during the cleanse but never long enough to put your body into starvation mode. You do lose some weight, but that's not the point of the detox.
One phase is the kidney cleanse and then liver and gall bladder. Lots of watermelon. Then smoothies, green salads, veggie juice, or anything you've liked that you've eaten in the cleanse so far.The last phase adds foods back in like more grains in the meals (guacamole, salads, soups).
Today is day 5 and I will be drinking 3 quarts of green smoothie. These smoothies aren't sweet at all. But I am so excited to finally start adding fruit back into my diet. We just finished 4 days of absolutely no sugar, not even from fruit. In 4 days I've lost 4.8 lbs. I think day 3 was the hardest for me. Headaches and weakness, but today I'm feeling good.
