Watching Joe Cross' documentary "Fat, Sick, and Nearly Dead". It mainly follows the filmmaker and his journey toward good health. His actions may seem extreme to some. Cross goes on a "Juice Fast" (Pure, fresh mostly-veggie, some-fruit juice) for 60-days to get his life back on track. At the beginning of the documentary, Cross is overweight and extremely ill and he decides some serious lifestyle changes are in order. The juice fast requires a) one juicer, b) lots and lots of fresh veggies (according to Cross' calculations, the average juice fast costs about $420 a month), and c) a shitload of will power. For two months, Cross doesn't eat anything; only drinks fresh juice, no matter where he goes and what he does.
It does sound extreme, but it definitely works. The transformation is incredible, both superficially and from a health standpoint. He ends up eliminating an illness that plagued him for years with the new lifestyle changes.
An inspiration toward healthy living to be sure, but a little unrealistic for those of use that can't afford the price.
