I don't get why people are turning to a drug, when a Paleo-esque high fat diet may do more than any drug ever would.

Theres a rather popular blog about one dude's struggles with Hep C, and hes been through a Sofosbuvir+GS-5816 trial, but otherwise has been fighting Hep-C with a high fat no grain diet: http://hopefulgeranium.blogspot.com/

Edit: Don't know why people are downvoting me. I'm not even going to hazard a guess on this one. Its a rather scientific blog that frequently links to studies being done on Hep-C, ran by a guy that has Hep-C, and I've been following it for over a year.
