Sir Lance-alot, you are literally my favorite letsrun poster by far and we have agreed (us against the world!) on tons of other threads when I post under other names, but your really are not up to your normal nuanced speed here.
"They are basically admitting that not eating a lot of meat or fat might be, you know, healthy! And let's say it isn't the reduction in meat or fat that is helping these healthy lifestylers, maybe it is less calories total, or a little more exercise."
I will say, for like the zillionth time. If all you are going to eat is corn fed meat, then yes, don't eat very much of it. No studies on meat differentiate because grass fed meat is something you have to go out of your way to get - it isn't on the .99 menu at Wendys.
And I never said grains and carbs are evil. Mischaracterizing a person's points is not something you usually do. I said that runners don't need 70% of their diet to be carbs, and that people vary greatly in their insulin response and if you are eating carbs that are turned to fat anyway at the cost of insulin and the issues around it, why not eat the fat directly in mono/poly unsaturated form? I think that too many natural mesomorphs look at us skinny runners scarfing down pasta and bagels and struggle on such a diet despite having good willpower and an active lifestyle. And I also think sub-clinical sensitivity to gluten is more common than you think. I am talking about optimal health, not that whole grains are unhealthy for everyone or even most people.
I do not think whole grains are the devil or bad for people. I think if you have a strong insulin response (do you stay full for hours after a pasta dinner in proportion to calories consumed? Do you stay lean on a diet like this in proportion to your calorie intake/calorie use?) and you experience no allergy symptoms, you will probably be just fine eating all these whole grains.
I know that there are people reading this who eat just as little as their little ectomorph counterparts, run just as much, yet can't get rid of the little fat rolls and they feel hungry all the time despite a high calorie demand. These are the people who might find a paleodiet works for them. It isn't a religion - it is a set of guidelines that you tailor around.
So, please, respond to what I say, not a strawman of what you think I am saying.
