I was watching the Tour de France, and the TV station would put up the heart rate readings of some of the riders during various portions of a stage. On flat stages during the middle of the race, many riders would have heart rates of 140-150 BPM, which is probably 70-75% of VO2 max for them. And they're COMPETING in one of the most intense endurance events in the world, so a recreational ride would be considerably less intense (though somewhat offset by fitness levels). Of course, during mountains, or key portions of the race, heart rates would get up there, but it isn't like these guys crank at 85% of max for 5 hours/day every day. Plus, I find that something about cycling really makes me feel alive - maybe its the speed? #4: I’d say mountain biking (and even road cycling) definitely fits in with PB: downhills, flats are done at relatively low intensity (i.e., low-level aerobic work), and the hills are high intensity spurts.

Obviously, Grok didn't have a 5" travel trail bike with Sram X.0 or anything with wheels for that matter....so he wasn't doing a whole lot of bike riding. I think mountain biking bounces between interval training (though often longer than other types) and active play, fitting in into the Primal Blueprint (even if not perfectly). I think the thing that pushes it over the edge to primal-enough is the fact that it gets you in the woods and connects you to nature more than anything in a gym could. #4- As a long time mountain bike racer, I’ve thought about this a bunch.

I am not 100% sure of this: "Ketones are a high-energy fuel that nourish the brain," Dr. Theodore VanItallie, a medical doctor and professor emeritus at the College of Physicians and Surgeons at Columbia University in New York City. He has been researching ketones for more than 35 years. Dr. VanItallie studied the ketogenic diet's effect on Parkinson's disease. In his study, five patients stuck to the diet for one month, and all of the participants' tremors, stiffness and ability to walk improved, on average, by as much as 43 percent. Additionally, ketones may be beneficial to those with Alzheimer's, Huntington's disease, multiple sclerosis, Lou Gehrig's disease, and Type I and II diabetes. http://www.tampabay.com/news/aging/article879333.ece Angela:

While the body can run off of ketones quite well, the nervous system is a different story. It tends to not work so well without any glucose at all (in the primal blueprint, I believe that fruit and other "primal" sources of carbohydrates are sufficient for adequate nervous system functioning). But if you're comparing JUST ketones or JUST glucose for brain functioning, glucose wins without a doubt. Like I said...not the same for other systems, though.

Could it be that the brain works better with ketones than glucose? I wouldn't be surprised...

I don't understand why would cheese be insulinotropic. When I hear that beef and fish have the same effect (do you have references?) I get very confused and sad. I am trying to deal with acne and according to Cordain I should give up dairy products. It's not really clear though. Dairy products means cow milk products. Does that mean that sheep and goat milk products are OK? I don't think this is what they mean. Can somebody help?
