Pushing the "eating whole unprocessed foods" meme WILL NOT WORK. Vegans eat whole foods. Fruitarians eat unprocessed foods. "Whole wheat" is considered a whole food by the vast majority of the population. And most Primal foods are processed just as much as any other type of food.
Bringing up Grok WILL NOT WORK. Does the patient even believe in evolution? (Surprisingly, many Americans do not. I don't know about Aus.) And if the patient does accept evolution, he probably thinks that 10,000 years of grains is evolution enough. We've been eating grains "forever" and it hasn't killed us yet. Plus everybody pre-1970 was skinny and they ate wheat...
Primal is so against CW that it takes weeks or even months to convert someone. Do you really want this doctor to get into a semantic argument about why whole wheat isn't really whole, or why bacon "isn't" processed, why coconut oil is good but corn oil is not, despite 40 years of teaching, or who the hell Grok is and why is Raw Meat Paleo Grok is OK but Ancient Roman Wheaties Grok isn't good enough?
How is anyone going to have this conversation IN THE FREKIN' ER.
I think the Doc needs to skip the science and go straight to results.
"I hear that GERD is a sign of gluten intolerance. No, not celiac, just an intolerance. Like lactose intolerance. It doesn't kill you it just gives you gerd. If you stop eating wheat you may not need Prilosec. Sometimes you can have a little, but we need to eliminate entirely first, to make sure that is what is giving you GERD." [also works for arthritis, skin rashes, high BP, and other signs of inflammation.]
"We've all heard the sugar is bad. Well, pretty much any bread that you eat, or cornbread, or rice, or white starchy stuff, turns into sugar in your blood. Your body doesn't know. We're all eating a lot more sugar than we think. You'll have to cut down on bread and potatoes because it's sugar. And YES, whole wheat still have the sugar in it." [can also relate sugar to blood sugar and use the diabetes angle.]
"I found out wheat and corn are what really make you fat. I know this because I stopped eating grains and".... lift up shirt to reveal six-pack. That tends to get a LOT more attention than biochem.
"I heard that Paula Deen lost 32 pounds by cutting out bread and potatoes. Can you try that?"
"you heard about all the low-carb diets? And how hard it is to count carbs? Well if you knock out the high carb starches, it's a LOT easier to stay under that carb limit."
Keep it simple, relate it to something they already know, as a stepping stone.
5'0" female, 43 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Gained to 110 on sugar cheat. Reset with 85P / 90C / 90F. Currently weaning off fat to 85P / 90C / 60F.
MY PRIMAL: 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 other need to tweak Primal to their own needs.
