A very informed exchange of information between Pruzicka, PaleoGal, and Yuneek.
I share their views largely, but I agree mostly with Yuneek who points out that super slow is seldom high intensity work. It primarily recruits ST and, maybe, the FTa fibers. Primarily in the eccentric phase. This would help resolve Pruzicka’s concerns about the ability to do high intensity on this high fat diet. It is true that gluconeogenesis would refill the muscle fibers over time, even on a high fat, moderate protein diet (15 to 20%, but at least 1.5G per kilogram of body weight [too much for a fat person, but fine for a lean one]). So, I think this experimenter should have little problem doing his super slow routine because he is not really depleting the muscle glycogen dramatically, if at all. I find that I require adequate carbohydrate, though only what is in vegetables and fruits, to sustain the balance in my energy requirements. This is so I do not depend overly on gluconeogenesis and end up eating lean muscle tissue to refuel glycogen.
One aspect of super slow that does use more energy than the heaving most people do is that maintaining the slow pace recruits a lot of postural muscles in the trunk. It also forces one to use the muscle engaged in the movement rather than heaving with the spine.
But, it does not use heavy or rapid enough moves to go up the fiber hierarchy to hit the FTb fibers. These movements cannot fire the largest motor neurons that fire the FTb fibers. There is a threshold of intensity that one must go over to recruit maximum muscle mass as well and these moves cannot possibly do that. Moreover, when you move super slow you will become super slow. Your neural circuits learn to move in the way you use them. It cannot be otherwise.
Another thing I have some concerns about is the issue of the antioxidant content of this experimenter’s diet. Inuit eat organs of the animals they hunt; kidney, liver, pancreas and so on. They contain lots of important antioxidants; in fact kidney (I may be recalling the wrong organ here) is very high in Vitamin C and is set aside for pregnant women. Unless this experimenter is eating organs along with the other elements of the Innuit diet, he may promote high levels of unquenched free radicals.
Sorry, PaleoGal, but a dip is not a high intensity move. A dip with 100 or 200 pounds on a belt is a high intensity move. Chin ups the same; I used to do them with my grandson hanging onto me. Now I just use the machine in the gym (no cables for this move they create too much momentum that can damage shoulders and tear rotator cuffs). I am up to the full stack now for a rep or two.
The comment from hokie99cpe shows just how potent healthful eating can be. The point about the signal to noise ratio is very important. When you eat what and the way most people eat your system loses its control. See my essay on this. If there is either too much energy intake relative to expenditure the homeostatic mechanism is operating far out of the Paleolithic range and lacks resolution. Your body literally does not know where it is the the energy landscape. This is especially true of energy expenditure. The Paleolithic level of energy expenditure was about 2 times basal metabolic rate. It is about 1.2 for Office Worker. Our energy thermostats are set to operate at this higher range and with the large variations it entails. So, they lack resolution at this low setting and the variations are too small to be detectable with any sharpness. A flat, dull energy landscape dulls the senses. A surfeit of energy intake does the same thing.
This is what hokie99cpe is finding because by going to a more Paleo diet he has cut his energy intake substantially. A body no longer in surfeit can sense energy needs more reliably so the appetite becomes a better guide to intake. Now, just get the expenditure part of it up and watch what happens. This is pretty much what happened to Wonderwoman on the Evolutionary Fitness diet alone. Bagels that used to look good are now repulsive. Breakfast cereal with a banana, which always gave her a stomach ache, is gone with welcome relief.
