Are you trying to be sensational with your title?
From the post:
"I hope people do not take this as some kind of attack on low carb diets – couldn’t be farther from the truth. There is NO AGENDA. Again, NO AGENDA. (It’s worth noting I consume a high fat, high protein, high fiber diet). "

I'm very interested in their findings, as I believe low carb is what screwed up my gut last year and let to a long period of constant constipation.
