Not to mention, the dependency on just basic nutrients that support the mitochondria.
Eric BergHOST
14:01
There's this thing in the mitochondria called the Krebs cycle that maybe you've learned about, and I'll guarantee rarely anyone understood it back then.
Eric BergHOST
14:09
You'd have to really play around with it to really grasp or wrap your wits around it because it's a very complex machinery.
Eric BergHOST
14:17
But the simplicity is your body's turning food into energy using oxygen.
Lee CowdenGUEST
54:36
of triggered me into curiosity.
Lee CowdenGUEST
54:39
So it turns out that malic acid is probably the rate-limiting step for the Krebs cycle, the tricarboxylic acid cycle inside of our mitochondria that makes energy for our cells.
Lee CowdenGUEST
54:53
And so if the cell is missing enough malate to produce ATP energy, then it makes sense to give the magnesium as a malate so that you take care of two birds with one star.
TanyaHOST
55:07
It sure does.
Mark PettusHOST
54:00
And so there are many well-established, universally accepted mechanisms whereby these interventions would benefit the brain.
Mark PettusHOST
54:12
And this is just a, I think it's the last slide, a little bit of a table on a bit more detail of how we know that people with mental health diagnoses have metabolic challenges and whether it's mitochondrial dysfunction or oxidative stress or disruption of many of these neurotransmitters produced largely in the gut, as you point out, that a ketogenic therapy improves mitochondrial biogenesis, right? Reduces reactive oxygen species, provides alternative energy sources via ketosis, replenishing acetyl-CoA in Krebs cycle, right? Regulating neurotransmitter, whether that be through changes in the gut biome and intermediary and gut metabolites versus direct effect on brain function.
Mark PettusHOST
55:16
Increasing GABA levels while decreasing glutamate.
John BagnuloHOST
55:22
Yeah, that's a big one, Mark, because I don't think a lot of people are familiar with the the potential for glutamate and glutamic acid to cause major mitochondrial issues.
Eric BergHOST
15:06
But I looked at nicotinic acid, and also B3 and nicotine, and it doesn't just cross over.
Eric BergHOST
15:19
It does not increase something called NAD, which helps you transport electrons through the Krebs cycle.
Eric BergHOST
15:26
So I'm not a fan of it, but there's other ways to get healthy.
SteveHOST
15:35
All right, very good.
Jarrod CooperGUEST
34:57
And then there's mitochondria markers, so for your energy organelles.
Jarrod CooperGUEST
35:01
So it looks at the key areas through the Krebs cycle, which produces your ATP, your energy.
Jarrod CooperGUEST
35:06
So markers that will show deficiencies that could be like CoQ10 or ubiquinol, key B vitamins, carnitine, those sorts of things might be the fixes in there, but it'll identify areas where the mitochondria or the Krebs cycle might be falling down.
Jarrod CooperGUEST
35:24
Then it looks at key nutrients.
Jarrod CooperGUEST
35:26
So it's pretty hard to assess some B vitamins in the body.

Jarrod CooperGUEST
49:51
But if you don't have the key co-factors like the vitamins, minerals working with them, then you get these steps going around to create molecules in the body so we operate well and feel good.
Jarrod CooperGUEST
50:04
But those steps fall over or they don't create what they're supposed to properly.
Jarrod CooperGUEST
50:08
And then that's when you start getting symptoms like the Krebs cycle from energy with your mitochondria or neurochemistry.
Dave AspreyGUEST
43:07
So by going into ketosis, you actually burn more of the white fat and you can increase the brown fat.
Dave AspreyGUEST
43:13
And your cells make energy through something we call the Krebs cycle.
Dave AspreyGUEST
43:18
This is, if you've heard of a mitochondria thing, this is the power plant in your cell.
Dave AspreyGUEST
43:22
And what it does is it burns a little molecule of ATP and then it recycles it.
Daniel J. GuerraHOST
41:54
And that urea then is ultimately, as I said, excreted, right? Okay.
Daniel J. GuerraHOST
42:00
So if you think about it, we're coupling the tricarboxylic acid pathway with the urea cycle, where fumarate, will re-enter the TCA, and the urea cycle will be fed by the TCA via transaminase reactions, aspartic acid.
Daniel J. GuerraHOST
42:26
Okay? So that's how you're generating the intermediates between the TCA and the urea cycle.
Daniel J. GuerraHOST
42:33
And ultimately also glucose can be generated.
Daniel J. GuerraHOST
42:36
So gluconeogenesis can play a role and can be functionally aided by the urea cycle.
Daniel J. GuerraHOST
22:10
When cells are stimulated in limiting glucose, So even though a loss of AMPK can restore some functions in glucose-restricted T cells, the cells don't fully initiate metabolic adaptation that would be necessary to recover full plenum ATP levels.
Daniel J. GuerraHOST
22:34
So in vivo, AMP kinase alpha-1 deficient T cells have a diminished mitochondrial respiration, there's an increased flux of glutamine into the mitochondria, which you know is the anaplerotic introduction of carbon from glutamine to glutamate via transamination out of alpha-ketoglutarate directly into the TCA.
Daniel J. GuerraHOST
23:00
And so the ATP to AMP ratios are all then funneled to those events in the mitochondria.
Daniel J. GuerraHOST
23:08
And therefore, when this occurs, there's a failure to proliferate And once that failure to proliferate is fully saturated, even the T cell function itself, its effector function starts also to diminish.

Daniel J. GuerraHOST

And then therefore ultimately will exhaust the glucose.
Daniel J. GuerraHOST
29:46
And yeah, they'll turn over just because of such events as senescence and polyubiquitinylation of the proteins.
Daniel J. GuerraHOST
29:56
which make up all of the intermediary metabolic activities, such as glycolysis, oxyappendylsphosphate shunt, beta-oxidation of fatty acids, transamination of fatty acids, the TCA cycle electron transport trend, and ultimately also the removal of reactive oxygen.
Daniel J. GuerraHOST
30:13
All right.
Eric BergHOST
15:30
Inside your muscles, what generates the energy is the mitochondria.
Eric BergHOST
15:36
I don't know if you've ever taken biochemistry before, but even if you have, most people still are still confused on what this Krebs cycle is all about.
Eric BergHOST
15:46
The Krebs cycle is like an assembly line of little things that occur inside the cells, inside the mitochondria.
Eric BergHOST
15:56
And your body is taking this food and transforming it into energy as ATP storage.
Eric BergHOST
16:04
and it's turning food into the building blocks so you can build up body tissue and body chemistry so that's simply what the krebs cycle is but what a lot of people don't know is when you go through the different points or stages on this assembly line you need certain nutrients for that to work if you are low in these certain nutrients you get a bottleneck.
Eric BergHOST
16:28
It just stops working, and that's going to affect the Krebs cycle, and that's going to back up your energy and your biochemistry of someplace which is occurring somewhere in the body.
Eric BergHOST
16:38
There's actually a way to test it, which I'm going to do some videos about, but the point is you want this entire assembly line to be free-flowing without any micronutrients missing.
Eric BergHOST
16:49
I'm talking about iron, b1 b2 b3 b6 b5 about magnesium i'm talking about manganese and another nutrient called coenzyme q10 right that's in the mitochondria as well well guess what when you have red meat you don't have to worry about it it's all in there if you have a high quality like grass-fed beef or hamburger whatever all of those cofactors everything i talked about is in a package it's inside there you have everything you need to build muscle and repair the muscle these people that are cutting out red meat they're maybe doing chicken breasts which has way too many omega-6 fatty acids and it's definitely of lesser quality and so is like plant-based protein that's like really low on the list whereas sometimes people think those are clean proteins to help you they're not there's other things you can do too you can do eggs and those are good but if you do eggs make sure they're not raw because the raw can deplete your biotin and it's not nearly as bioavailable as the cooked eggs another protein that's not bad is a real good high quality cheese okay think about it where does cheese come from it comes from milk in nature when does an animal need milk when they're growing why because milk has a lot of growth factors to help muscle building and so a little bit of cheese can do wonders on your muscles for growth and increasing muscle size Just don't do the low quality cheeses.
Yeshe KaytupHOST

the air is full of Qi you are breathing in the Qi the movement in your cells especially the cells around your uterus and generative organs there's movement in the cells there's cellular respiration where Things go in, foods go in, foods go out.
Yeshe KaytupHOST
35:11
There's the Krebs cycle.
Yeshe KaytupHOST
35:13
All of this is going on.
Yeshe KaytupHOST
35:15
This is not making energy out of nothing.
Yeshe KaytupHOST
36:16
We're all on fire.
speaker_1UNKNOWN
36:19
We're all alive.
Yeshe KaytupHOST
36:23
The energy you are using for the heat of tummo is created by the slow burn oxidation of the Krebs cycle, which is dependent on bringing in oxygen molecules and conjoining them with carbon molecules and using the heat off of them.
Yeshe KaytupHOST
36:45
It's how you stay alive.
