The basic premise of this book is that if you give your body a break from having to expend so much energy digesting food (and particularly food it was never meant to consume), it can finally get around to detoxing and healing.
The book advocates an elimination diet where you CANNOT eat the following foods:
-Oranges, orange juice, grapefruit, strawberries, grapes, and bananas
-Dairy and eggs, milk, cheese, cottage cheese, cream, yogurt, butter, ice cream, nondairy creamers
-Wheat, corn, barley, spelt, kamut, rye, couscous, oats
-Raw fish, pork, beef, veal, sausage, cold cuts, canned meats, hot dogs, shellfish
-Soybean products (soy sauce, soybean oil in processed foods, tempeh, tofu, soy milk, soy yogurt)
-Peanuts, peanut butter, pistachios, macadamia nuts,
-corn, creamed vegetables, tomatoes, potatoes, eggplants, peppers
-butter, margarine, shortening, processed oils, salad dressings, mayonnaise, spreads
-alcohol, coffee, caffeinated beverages, soda pop, soft drinks
-refined sugar, white or brown sugars, honey, maple syrup, high-fructose corn syrup, evaporated cane juice
-chocolate, ketchup, relish, chutney, soy sauce, bbq sauce, teriyaki sauce, other similar condiments.
You have 1 smoothie or juice (made in your juicer or blender) for breakfast and one for dinner. You have an elimination diet meal for lunch. If you are hungry, you may have a small mid-morning snack and late afternoon snack. The book suggests you drink water if you think you are hungry and see if that does the trick. You are also to drink lots of distilled or filtered water throughout the day.
You must have a bowel movement every day and if you don't, he wants you to get a colonic (they are quite expensive) or take herbal laxatives or do an enema. Either way you must have a bowel movement.
Another big rule is that you must wait 12 hours between dinner and breakfast.
There are a few other points, but you'll have to read the book for those. :)
For me, I think the concept sounds good, but after 12 days on the program (ideally you do it for 3 weeks), I was so hungry I could barely think. I got off it and ate everything in sight. Guess it just wasn't the program for me.
