Hi- juicing is wonderful for losing weight. I have lost 15 lbs. in one month, and eliminated or reduced 75% of my health problems. I have read that it may be hard to do in cooler climates, but I live in Florida where it is still shorts & tshirts season.
There are some particular juices that are more beneficial than others for weight loss, so I would recommend visiting your local library and browsing their various juicing books.
I am using a Jack LaLanne juicer that I bought brand new on Ebay for only $75 including shipping. They also have it at Wal-Mart for under $100.
Good Luck.. juicing really is the key to health and weight loss.
