High Metabolism Keto possible?
-
For anyone who uses Twitter, this account caught my attention. https://x.com/exfatloss
He also has a blog: https://www.exfatloss.com/Basically, he is eating a high fat, low carb, low protein keto diet with heavy cream as a staple and claims to have a very high metabolism - feeling very warm, high temps, high Testosterone (over 1000) and very low TSH. (0.198)
He claims that Peat is wrong in the saying that Keto can't be a pro-metabolic diet.Thoughts?
Perhaps protein being anti-metabolic matters the most, and not whether you eat carbs or not.https://x.com/exfatloss/status/1732849040952623289
Some of his tweets:Ray Peat was clearly bonkers-level wrong about keto, and Peatists just can't accept the truth.
Just like ketards who can't accept infinity protein isn't the only solution, or that seed oils might be more important than carbs.Yea, I think Peat is right on many things - he was anti-PUFA and wary of high BCAAs, and probably many others issues I haven't read about yet (I've only read a bit of his writing).
Modern "internet keto" is, in a sense, a death trap for many - it's "bacon bacon bacon!" all the time, it implicitly encourages many people to consume e.g. salad dressings with soybean oil and high-PUFA chicken/pork, and way too much muscle meat.
But keto can also be done low-PUFA and low/moderate/adequate BCAA.
The idea that nobody, anywhere, could possibly be healthy on keto long-term is what I'm taking issue with. -
@GreekDemiGod I dunno man. I don’t see any pics, (almost seems like hiding behind royalty free images on his blog). Seems kinda “upset” (which is one of my indicators for poor health). Says he uses an IR forehead thermometer, (those are known to be poor instruments) and should be taking underarm temp, (which can vary as much as a degree from other places).
I’m not saying it isn’t possible. Peat certainly seemed to think protein was less important as he got older, (so perhaps it’s a limiting factor in an animal based diet?). It just seems like there isn’t a ton of evidence from this persona.
One last thing I found interesting was that someone shot him a study in his replies and he responded “tldr.” Aversion to reading studies is something I used to have before I got my brain back on line with higher carbohydrate consumption and thyroid.
You could always trial it?

Test his acid-base balance.
He won't pass that test. He lacks CO2 production. The sugar he burns is thru glycolysis, and he produces a lot of lactic acid.
He also is likely to produce plenty of cortisol to produce sugar from protein. This affects his immunity as cortisol destroys the thymus gland, and this is where T-cells mature. He needs the sugar for his brain and red blood cells, as that is the only substrate they use for energy.
With an acidic ECF, he faces long term consequences. His cells will lack potassium (as potassium goes into blood in exchange for hydronium ions to try to keep blood alkaline) and his cells won't be able to regulate the ingress of calcium into the cell. He will have tachycardia as his heart as a muscle fail to have the optimal ionic gradient of internal and external calcium to contract and relax properly, and will be strained as it inefficiently pumps blood with more strokes needed to do the job. His organs will develop fibrosis as a result of the poor regulation of calcium into the cell. He is primed for kidney, liver, and heart failure. If cancer doesn't get in the way and end his life first.
Funny thing with people who use only an incomplete set of biomarkers. Because knowing too little of our biochemistry is dangerous.

Thanks for sharing it. Only my current angle herein.

I probably wouldn't take advice from the person who wrote that. But maybe they were having a bad day.
Keto seem risky to me. But I guess, whether it is to them depends on context behind them, what their goal is, what they mean by "healthy" and "long-term".

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.

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

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.
