A study about muscle fuel under different training intensity:

http://jp.physoc.org/cgi/content/full/536/1/295

The subjects followed a high carb low fat eating protocol. They speculate that the "measured" relative decrease of FFA oxidation when training intensity passed a certain level is related to decreased levels of free carnitine. Fatty acid availability did not decrease. Maybe free carnitine levels are more easily maintained in a keto adapted person. Speculation upon speculation...

There's a lot of "truthiness" in this thread.

Insulin is a hormone.

This is day 68 on the all-meat diet for me.
Yesterday, my doctor adjusted DOWN the amount of dessicated thyroid I have been taking for the last four years. She said I was overcompensated ... suddenly!
Is it diet-related? And if yes, how would a zero-carb woe influence the thyroid efficiency?

Yes, and it is also a protein. The two are not mutually exclusive.

Wonderful article, Klein. This is the sort of "black box busting" study we need on this thread!

Of course, WAY BACK in post #324 I asked Bear about this VERY thing!BTW... although they mentioned the substantial increase in lactate levels after exercise became more intense, especially during high-intensity exercise (because the flux through the glycolytic pathway and the pyruvate dehydrogenase complex reaction would greatly exceed the flux through the TCA cycle... in other words, anearobic respiration).

Perhaps there may be an adaptation to higher cytosolic concentration of carnitine in an FFA-adapted individual? However, how would this ever obviate the need for the glycolytic pathway (using glucose) to get involved, under anearobic conditions?

Look deep into the black-box.....

ubizmo, this was covered WAY BACK in this thread.The use of muscle tissue would be to spare the bodyfat in a starving person. See... fat IS the preferred macro and micro nutrient for our bodies.

Main thing is, although Bear was the one who brought up the glycerol being used for glucose needs, he never fully understood the GNG pathway that was used by the liver. I guess physiology is not his "strong suit".

So, Wooo... on a zero-carb diet, after becoming fully FFA/keto-adapted, would glycerol be used as the substrate, or amino acids?

Only the "black-box" knows for sure!

Ahem! I think Rosebud KNOWS that! I just love it when one nurse corrects another one like she is actually revealing a big secret! LOL

I was not correcting, just adding. Sorry if I offended you.

You didn't offend me at all, but I believe the subject had already been covered several pages ago.

I have heard of people decreasing their thyroid because they have lost weight. There is an equation for determining dosing range that is based on weight. The equation is posted in the thyroid area.

I have a life other than this Thread; I guess I missed the post where this was "already covered several pages ago."

Ok, I guess it has finally come to the end for me.

The thread has become infested with parasites who take our time but don't contribute anything but noise.

I began this to inform people who have a bodyfat problem about the highly 'unsocial' diet that is our evolution-imposed real diet.

First I encountered those who are addicted to 'some' veggies. Then those who are compulsive counters of calories and readers of 'scientific' studies which contradict my experiences. This was followed by the pedantic control freaks who 'know' that my lifestyle is flawed. After that the parasites who cling to their acculturation and feel obligated to attack and render useless anything which contradicts their belief systems.

The final straw was the ******** who impugned my knowledge of the cancer which threatened my life. This ********* finally brought me to the realisation that I am simply wasting my time wading through a daily pile of hundreds of meaningless unproductive posts to find a genuine question from the few who are really interested in changing their body shape, health and lifestyle.

SO, it has been an interesting trip, thanks to those who CAN follow and have supported me, but I am now departing to leave the thread to the parasites and mercenaries who have stolen it.

Any one who is interested in the path and has any genuine questions on how to implement this controversial way of eating is welcome to visit my website and send me an e/mail.

Goodbye and- 'Thanks for all the fish'.
