Just watching this documentary on NetFlix (along with ever other food doc I could find lol) and it was very interesting.
http://www.fatsickandnearlydead.com/A man from Australia does a juice fast, where for 60 days he only drank home made juice, made out of vegetables and fruit. After the 60 days he lost something like 50 pounds, and doesnt have to take his medicine anymore for a skin condition he had. After seeing this I went out and bought a juicer because I wanted to try it, it seemed worth while. Let me tell you, it is not easy. Yesterday was my day 1 and I caved it at about 8 pm and had some peanut butter and crackers, lol.
It is on NetFlix Instant and all the other instant watch services. I highly suggest it if you're interested in getting healthy like me, or just want to lose weight.
Another one I recommend is called Food Matter, which is also on instant watch.
(This might belong in discussion now that I think about it. Move if it does please.)
