Surely the OP can do something? The Primal-Screed-In-10-Minutes is clearly too crazy, but at the same time, I don't want him to suck it up and push CW for four years.
A patient could probably handle ONE thing. If you could convince them to do ONE thing, what would it be? If I were the OP, I would play up either of these:
1. The GERD angle: I don't know if there is proof, but there is a lot of anecdotal evidence that GERD is a symptom of gluten sensitivity. Maybe you could suggest this to the GERD patients. Switch to the gluten-free stuff and see if the GERD gets better. Don't mention weight at all. If ditching gluten works on the GERD, maybe they'll come back for more information.
2. The "whole unprocessed foods" angle: I know I know, I'm the MDA poster who is always hatin' on the phrase. But maybe you could convince a patient to at least start with whole ingredients and cook everything themselves. Including baked goods, if necessary. "You want bread, fine, make it yourself. You want beef? Fine, make your own lunches with meatballs." At the very least, that will take them off the worst of the offending chemicals.

I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I advocate a two-month strict adjustment for newbies. But everybody is different and should tweak Primal to their own needs.
