Don't mix fruits with vegetables - with the exception of Apple which mixes fine with vegetables. A good basic recipe for juice is an apple, 4 or 5 carrots, 1 or 2 stalks of celery. Beets are a good addition and the whole beet, including leaves can be juiced. For variety I add tomato or cucumber or a bell pepper. Cilantro leaves are a good blood cleanser and can also be added. And a clove of Garlic is good too. There are dozens of combinations of vegetables. Avacados or bananas will not juice.

Yes, everything I have read says to dilute the juice... I dilute about half with pure water. If you don't it could cause your pancreas problems.

Most every book I have read on fasting says to do enemas... they are not difficult, and will prevent the toxins that are going into the intestines from being reasorbed for reprocessing in the system.

Since you will be fasting to lose weight, make sure to do a Liver Flush at the end of your fast to prevent Gallstones from forming.

Breaking the fast is the most important part and when you could really cause yourself damage. You might want to explore the inter-net or read a book before starting your fast.
