Did you know that the only food edible my man that has a negative calorie count is raw celery? (Ok, elephants can chomp thru all kinds of raw vegetation!) It burns more calories to ingest and digest it than it has.  That is because fiber takes a lot of power to break down, and particularly when celery is raw, its got lots of tough fiber.  My pal Stephen turned me on to one of my now fav juicing recipes: Celery, pear and ginger.  Fabulous!!
