My wife added veggie juicing (absolutely no fruit) to her already healthy diet and it helped. She did not do a total juice fast. But focused on raw vegatables, lean meat, no sugar, no wheat, limited whole grains, fish and eggs. Plus vegatable juices. I saw an improvement and would recommend it if you can tolerate vegatables. Just one trick, make sure the juice is at least half easy juice, which means half celery, carrot or cucumber (or combo any of the three). the other half can be any vegetalbes you tolerate except not too many beets they can cause a heart reaction in large quantities, also no spinach in large quantities it can cause gout or something funny like that. Anyway start with easy juices and add the more intense vegatables.
Search the internet on vegatable juicing you will find the guildelines.
