Maybe Mark is on vacation and let someone else manage the store
I know we are all after optimum health through diet (and exercise) but sometimes in reading a lot (maybe most) threads people trying to over analyses or maybe trying to overly bioengineer their diets. It's a lot like trying to apply animal husbandry to ourselves.
I tend to step back and ask: Based upon evolutionary human biology that formed my ice-age hunter/gatherer ancestors' diet, physical activity, and body composition (Sisson's "Grok" is a good metaphor), how would I best mimic their diet and lifestyle to reach my fitness goals? I figure evolution had a longtime to workout the problem, and by following that basic prescription I'm probably going to be fairly close to those goals. I may not know exactly the macro ratios they were eating but I know what they weren't eating (or not eating throughout the year).
I don't know the Guest poster. He read like he was down on all fiber. I don't really care what he thinks although I think some of his arguments about supposed CW health benefits are probably overblown or non-existent. From a Primal/Paleo POV it doesn't make sense to go out and buy a box of All Brand to get my fiber. I'll just keep eating real food based mostly on my meats and vegetables. Now if I could quit drinking so much wine and snaking on cheese and/or nuts most week nights - but I enjoy them - It be easier for me maintain my desired body comp.
Would I be putting a grain-feed cow on a fad diet if I took it out of the feedlot and put it on pasture eating the grass nature intended?
