High Metabolism Keto possible?
-
I was super hot the first few months on keto carnivore (lots of dairy fat and clabbered milk), and I'm sure my pulse was up (but didn't check). it's been established (so I thought) that adrenaline can compensate convincingly for a while to maintain metabolic rate.

Funny thing with people who use only an incomplete set of biomarkers. Because knowing too little of our biochemistry is dangerous.
Your spot on (again).
Here is an interview that I found to be helpful.
https://mercola.libsyn.com/low-carb-cortisol-and-glucose-discussion-between-georgi-dinkov-dr-mercolaGlucose — when it goes through the mitochondrial transport chain — burns far “cleaner” than fat, creating almost a minimal amount of reactive oxygen species (ROS)
If your fat intake is higher than 30%, glucose will be metabolized through glycolysis and not in the mitochondria, which increases lactic acid.
The fat percentage limit for most healthy people is likely around 35%, whereas diabetics and the obese may need to limit their fat intake to 15%Your body releases cortisol to produce endogenous glucose when your blood sugar is low. Cortisol breaks down your lean muscle, bones and brain to make amino acids that your liver then converts to glucose. Cortisol also promotes inflammation

Thanks for backing it up with haidut's interviews, from which I get a lot of material as well. But you're very organized that I appreciate from myself being very bad at. I just couldn't get all that in for organized such that I can always access it as reference.

Waking up at 99.4F is pretty clearly high cortisol and stress hormones. T can be high from a stress response, not being readily taken up by the cells and converted a lot to estrogen. And TSH can be suppressed by stress hormones. That’s all the Peaty cope I can come up with.
If anyone wants to try that diet long term good luck

He probably just wasn't done
Actually it's far more likely the reader isn't done, or needs to reread. Far more likely I am the problem.
Also plus one for Yerrag's analysis up there.
-
@BroJonas how is this worse than someone with low waking temperature and low Testosterone? That someone doesn’t even have the adrenal resources to regulate his body temperature to an optimal level.
-
He is very accessible on Reddit (on the r/saturatedfat subreddit) or on his blog. And I think he also like to do experiments. For example he just carried out a test measuring his "calories out" and which costs near 1000$ (if I remember correctly).
Thus, we might convince him to do cheap blood tests to find whether he really has high cortisol or other metrics?
-
@NNight He has also posted cortisol tests, all in range.
https://x.com/exfatloss/status/1787899476767600743Oh, and he's been doing it for 8 years.
-
I wonder if we can follow the range of the medical complex, as the range set is very loose. If the population (is the sickly US population) is the basis for range, then at the very least to consider his cortisol low, his cortisol has to be low of range. But is it?

Lots to add here
But I’ll keep this brief
1- have you heard of long keto expert Jimmy Moore? Check him out. It will be relevant with a small search- and speak volumes.
2- I have to assume- most of this exfat guys health comes from robust kcal not magical keto.
3- attacking Ray Peat is infantile imo. High estrogen or serotonin. Who knows. But it doesn’t help his optics.

@Peatful
About Jimmy Moore (https://www.reddit.com/r/keto/comments/apbzv7/comment/eg7c7f0/) :He's a glutton, that's the explanation. He gorges himself on unlimited fat and calories and eats low protein. He thinks if you don't eat HUGE amounts of fat, you become 'fat deficient'
It looks like the kcal haven't made him any favor.

Im not looking at reddit comments for understanding - but physiology.

Notice how when someone with a healthy metabolism eats high animal fat, low protein/carb, they are proving a keto diet to be pro-metabolic, but when someone with a poor metabolism does the same, they are a glutton? Thus the keto advocates implicate CICO, negating their sophisticated theories surrounding "type of calorie (aka sugar vs fat)" over CICO.
-
There is no keto diet.
-
@NNight there is to keto advocates
-
@LetTheRedeemed
Yes, there are ketogenic dietS.
Drinking only seeds oil is one of them. -
"High fat oxidation" is possible with keto, but not the oxidative phosphorylation that Ray always talked about. It's basically impossible to retain CO2 in ketosis, that's back to square one really. The respiratory quotient, which even low-carbers agree with and use as a reliable way to indicate whether or not they're burning fat for fuel.
The person you're referencing on Twitter has fell into the same trap basically all the Hatch "disciples" have fallen into. You CAN'T rely on temps as a sole indicator of good metabolism. Ray also discovered this back when he first started taking thyroid. Before he took thyroid, he was eating upwards of 7,000 calories a day. After he started taking it, he stabilized out at around 2,500. Burning energy, and burning energy efficiently are not the same thing.
This whole concept about CICO not being relevant has really led a significant portion of this community astray. Also coritsol is thermogenic, and can fool you into thinking your temps are high because of good metabolism.
-
@LetTheRedeemed Agree.
There are several varieties of the keto diet. Some emphasis fiber from low-carb veggies, some restrict protein, other are more high-protein. There is also keto heavy in nuts. -
@Mulloch94 The problem is that you can't pinpoint one marker in his blood tests that suggest a bad metabolism or a state of health. That's the issue that arises. There is always some kind of cope.
Oh, his TSH is super low because high cortisol suppresses TSH
Oh, his Testosterone is ultra-high, but it's from stress.
"Oh, his temperature is ultra high, but it's from adrenaline, cortisol. -

"Oh, his temperature is ultra high, but it's from adrenaline, cortisol.Well I wasn't implying this person is necessarily unhealthy. I don't know. I don't know them or their environment. I was more or less just trying to answer your question in the title. High metabolism - as in high fat oxidation - is possible on (or in rather) ketosis. So no, in a very real sense, you can't have the same type of metabolic rate peaterians speak about while being in ketosis. It would be akin to saying you drive a automatic and a stick shift the same way, lol.
Now the larger question that looms, the one you're hinting at now. Is ketosis bad or unhealthy? I believe it to be, but that's just my beliefs. I'm always opened to being wrong. But I also don't believe you can point to a single marker on anyone and determine them healthy or unhealthy.
In fact a capnometer would probably tell you more than any blood test with regards to metabolism. High or low cholesterol can tell a lot too though. The biggest thing is the food volume itself. No healthy person needs 5, 6, 7,000 calories a day to be "healthy." Only people who train really really fucking hard need that much food, and, ironically, those people are typically not as healthy as the public thinks they are. I don't need a blood marker to know something is wrong with someone's health when they can't go 5 or 6 hours without any food.
