This interview options repeat visitor Georgi Dinkov who’s a digital firehose of data and an skilled on the work of the late Ray Peat,1,2 Ph.D., an writer and pioneer in diet, bioenergetic medication, environmental elements and regenerative processes.
A few of the info on this interview will problem a few of your lengthy held views because it did mine. All of us have conformational biases and I encourage you to let yours go for awhile and contemplate the chance that a few of this info may be true for you and others.
That is among the many greatest interviews I’ve accomplished in years, and we take deep dives into all kinds of subjects. The total interview is over three hours lengthy, so I’m dividing it into two components. That is Half 1.
This yr, on a near-daily foundation, I’ve been listening to Dinkov’s podcast for 2 to 3 hours at a stretch, and I typically repeat them two or 3 times, as a result of every episode is simply so chockful of data. If you wish to get a deep understanding of biochemistry and bioenergetic medication, his podcasts on his YouTube channel and weblog comprise a treasure trove of data that’s properly value your time exploring.
The excellent news is that you just don’t must pay something to be taught this info. No books to buy, no membership websites to affix; it’s free for the taking, a minimum of in the intervening time. Georgi doesn’t have his personal channel, however merely is a visitor on different individuals’s channels, which makes him onerous to deplatform.
However who is aware of what the longer term holds? If this materials pursuits you even a bit I’d encourage you to start out listening when you can earlier than it disappears. And, as talked about, I’d additionally strongly advocate that you just hearken to my podcast with Georgi a number of occasions as I’m certain that 99.9% of listeners won’t perceive or totally perceive this info except you might be uncovered to it a number of occasions.
How Does Cortisol Work?
Most of us consider cortisol because the stress hormone, however that isn’t its main function in your physique, which is to verify your glucose degree by no means drops too low, as that might end in a hypoglycemic coma which might kill you prematurely.
Each low-carb and fasting are nice interventions within the short-term for many who are chubby and metabolically rigid, however when used chronically they will harm your metabolism and result in well being problems as a result of they have a tendency to trigger power elevations in cortisol leading to irritation and catabolic lean muscle loss.
So, if you happen to don’t have sufficient glucose in your bloodstream, your physique makes glucose by secreting cortisol, which breaks down your lean muscle groups, bones and mind to make amino acids that then convert to glucose in your liver. In one among his latest podcasts, Dinkov defined that the first advantage of anabolic steroids is that they’re anti-cortisol. That is how anabolic steroids work to construct muscle mass.
Cortisol additionally makes use of up saved fats in a course of known as lipolysis. Whereas this may increasingly sound like an excellent factor, the issue is that it doesn’t do away with the dangerous visceral fats discovered round your inside organs that causes irritation. It burns your good fats, the peripheral and subcutaneous fats, which is beneficial.
So, in the end, power extra cortisol goes to trigger irritation and impair your immune perform. It additionally will increase meals cravings. So, you do not need your cortisol to be elevated repeatedly in an effort to rescue you from hypoglycemia. Therefore, a power low-carb weight loss plan is just not a good suggestion for most individuals.
Cortisol can be one of many main drivers of getting older. It accelerates the getting older course of, which is one thing only a few within the longevity neighborhood are even conscious of. Whether it is chronically elevated, you merely will die prematurely as it’s extremely catabolic, that means it would break down your physique tissues. To remain wholesome as you age you should be anabolic and construct wholesome tissues like muscle and mitochondria. Elevated cortisol will critically impair these efforts. Dinkov feedback:
“I believe there’s hardly a power situation the place you do not see cortisol implicated, and often, within the majority of circumstances, it’s elevated cortisol, not low cortisol. Actually, the one scenario by which low cortisol turns into problematic might be Addison’s illness, which is adrenal failure. And that is very uncommon.
Research way back to the Fifties and ‘60s demonstrated which you could produce each single phenotype of getting older if you happen to inject cortisol, or a minimum of create a state of relative glucocorticoid extra within the animal. So you are able to do it both by injecting artificial or pure glucocorticoids, or you are able to do it by decreasing the degrees of the pure anti-cortisol steroids within the physique.
These are pregnenolone, progesterone and DHEA. In males, testosterone and likewise dihydrotestosterone. Should you scale back the degrees of these anti-cortisol steroids and maintain the cortisol ranges regular, you’ll nonetheless obtain the identical form of phenotype of getting older. And that is just about what occurs to individuals as properly.
It has been proven that cortisol ranges don’t decline with age except you have got adrenal failure, whereas the degrees of all of those anti-cortisol, youth-promoting hormones decline with age. A number of intervention research have demonstrated that if you happen to administer brokers that oppose cortisol on the receptor degree, or scale back its synthesis, you possibly can obtain each well being outcomes and enhance the way in which you look.”
Excessive Cortisol Is Dangerous for Your Mind and Psychological Well being
Importantly, cortisol not solely shreds lean muscle, but in addition mind tissue, so elevated cortisol promotes mind atrophy, which is a trademark of each dementia and melancholy. Dinkov cites research exhibiting that administering anti-cortisol remedy to individuals with treatment-resistant melancholy put them into remission inside as little as 48 hours.
“So I believe it is an excellent argument that cortisol is catabolic to the mind, and clearly, if it is catabolic to the mind, it’s most likely not going to enhance your temper, if something goes to worsen it,” he says.
Essential Cautions Earlier than You Improve Carbs
So, it’s clearly vital that you should be doing every part you possibly can to maintain your cortisol ranges and power irritation low. However it might even be a significant mistake to extend your carb consumption if you’re nonetheless on a high-fat weight loss plan. I did this experiment within the mid-‘80s after I learn the guide by Harvey and Marilyn Diamond, known as “Match for Life”.
They instructed having fruit just for breakfast, which I attempted. Then I did my lab work and located my fasting triglycerides and lipoprotein profiles had exploded for the more severe. I prematurely concluded {that a} high-fruit weight loss plan was nonsense and remained comparatively low-carb, consuming little to no fruit for almost 4 a long time.
I not too long ago reevaluated this method after encountering Ray Peat’s work. I now perceive that I used to be lacking vital components of the technique. I made a decision to experiment with my consuming and now incorporate wholesome carbs, primarily from ripe fruit, a number of occasions a day.
Nevertheless, simply because carbs seem like a greater gasoline as a result of they generate much less reactive oxygen species in your mitochondria, one cannot indiscriminately enhance carbs in your weight loss plan with out paying strict consideration to the quantity of fats you might be consuming, and simply as importantly, the quantify and the kind of carbs you might be consuming. Failure to do could end in a lower in your well being and vitality.
The Important Metabolic Swap You Must Perceive
This is without doubt one of the most vital rules in meals science that I had by no means realized or understood till not too long ago. My robust guess is that that is additionally true for many pure medication clinicians. That’s the reason I created the determine beneath that can assist you visualize so you possibly can higher perceive this important idea.
Low-carb diets have helped a minimum of tens of thousands and thousands of individuals enhance their well being for an excellent cause, and that’s there’s a stealth change that controls what gasoline your mitochondria can burn, as they will solely burn one gasoline at a time: both fats or glucose.
The change has been given the title the Randle Cycle, however it’s extra useful to visualise it as a railroad change that modifications the tracks of the prepare, and the prepare can solely journey down one monitor, not each. It’s because just one kind of gasoline could be burned at a time.
The very best-case situation is you metabolize, or burn, glucose in your mitochondria with none reductive stress (a time period I’ll clarify in my upcoming interview with Georgi Dinkov). Whenever you do that, you’ll solely generate 0.1% reactive oxygen species (ROS).
Not solely does this route generate much less ROS, however it is also extremely environment friendly at vitality manufacturing by creating 36 to 38 ATPs for each molecule of glucose that’s metabolized. It can additionally generate metabolic water and carbon dioxide, that are additionally vital on your well being.
For this to happen, as indicated within the determine above, you’ll need to eat lower than 30% of your energy as fats. Whenever you eat considerably greater than that quantity, the change modifications to burn fats in your mitochondria and also you won’t be able to burn glucose till your fats decreases to lower than 30% of energy.
Since glucose is unable to be shuttled into the mitochondria to burn, it winds up backing up into your bloodstream, elevating your blood sugar. It is a main contributor to diabetes. What little glucose is burned for gasoline is completed through the use of glycolysis, which is a primitive pathway that micro organism and most cancers cells use.
It’s nice we’ve got this pathway as you completely want it for fast gasoline if you find yourself activating your kind II muscle fibers. But when that is the first method you burn glucose, you might be in a catastrophic metabolic state as you might be creating a great deal of lactic acid as a waste product as an alternative of wholesome CO2, and you might be solely producing 2 ATPs for each molecule of glucose, which is 95% much less vitality.
Lactic acid will increase reductive stress, which causes reverse electron move within the mitochondria and causes reductive stress, which will increase the ROS to three to 4%, which is 30 to 40 occasions greater than when glucose is burned effectively within the mitochondria.
Why Lactic Acid and CO2 Are so Essential
Bear in mind, if you find yourself burning glucose effectively in your mitochondria, the glucose is transformed not solely to 36 to twenty-eight ATP, however when the electrons from the glucose are in the end handed off to oxygen, metabolic water (deuterium-free) is made and, very importantly, carbon dioxide.
That is important to know, as carbon dioxide is a potent stimulator of mitochondrial biogenesis, which is able to enhance the variety of mitochondria that you’ve got so you may make much more vitality.
Conversely, if you find yourself burning glucose far much less effectively in glycolysis, you might be solely producing two ATP and somewhat than creating life-sustaining carbon dioxide, you might be producing life-damaging lactic acid, which is able to degrade your mitochondria and make them die sooner.
Too A lot Dietary Fats Impedes Glucose Metabolism
Bear in mind, the metabolic change occurs at about 30% fats. So, if you happen to’re consuming greater than 30% fats you are going to be principally burning fats, and glucose metabolism (oxidation) might be inhibited. Should you’re overweight, the cutoff for fats is probably going even decrease. In keeping with Dinkov:
“I’ve observed that between 15% and 20% [dietary fat] might be the place most individuals, of their present well being state, can metabolize the fats with out inflicting issues for the glucose by way of the Randle cycle. Particularly Sort 2 diabetics.
Most of them are chubby or overweight, which suggests they’ve two sources of fat — one by way of the weight loss plan and the second from their fatty tissue, as a result of there’s all the time some lipolysis occurring. So for diabetic individuals, it’s most likely a good suggestion to decrease the consumption of fats from the weight loss plan, as a result of they have already got so much coming from their very own our bodies.
There’s so many clinics around the globe that deal with and even remedy Sort 2 diabetes by placing them on a extremely restrictive weight loss plan till they lose most of their fats. After which out of the blue, the metabolism of glucose will get restarted. I believe this instantly exhibits you that the issue with glucose wasn’t the glucose itself.
It wasn’t the glucose that was fattening them up. That they had an excessive amount of fats of their our bodies, and when you do away with that fats, regardless of the way you do it, the issues when metabolizing glucose disappear which, to me, is a superb testomony to the Randle Cycle.”
You additionally don’t need fats to be too low, say, lower than 15%. Between 15% and 30% may be the candy spot, though, as famous by Dinkov, the perfect ratio of macronutrients isn’t identified. That stated, he believes, based mostly on epidemiological research, that an roughly equal ratio of energy from fats, carbs and protein (i.e., about 33% every) seems to be optimum for long-term well being.
I respectfully disagree with this, as I imagine 33% protein could also be too excessive except you weren’t consuming many energy. Consuming greater than 35 to 40 grams of protein at a meal is probably going counterproductive, as their absorption might be impaired, and you’ll be left with having to take away the ammonia and nitrogen, which might harm your kidneys.
At current, I imagine that getting 15% of your general energy from protein might be about proper when consuming between 2,000 and three,000 energy per day. Most individuals don’t want greater than 120 grams of protein per day. Past that, you begin burdening your kidneys. I’ve lengthy used the system of 1 gram per kilo of lean physique mass (not complete body weight), which Dinkov agrees appears to be a great method to decide your day by day protein consumption.
Weight Loss Rebound Defined
The Randle Cycle additionally helps clarify why many individuals who lose giant quantities of weight find yourself rebounding and gaining all of it again, even once they’re nonetheless proscribing energy. Dinkov explains:
“There’s all the time some baseline lipolysis occurring. And within the rested state, your muscle groups favor to oxidize fats. So, when you have an honest quantity of muscle mass, you possibly can burn most of this fats by way of this baseline lipolysis. The ratio of lean muscle mass to complete physique weight is the first determinant of your basal metabolic charge. So, it is crucial to not lose lean muscle mass.
I believe lots of people get themselves in a scenario the place, by way of excessive fasting or excessive train, they lose a whole lot of physique weight, however they don’t seem to be being attentive to how a lot they’re dropping of every of the 2 elements — fats mass and lean muscle mass.
A number of research have proven that over long-term fasting or a long-term exhaustive train, individuals lose a whole lot of physique weight, however about 80% of that’s lean muscle mass. So, they have been a lot leaner, however their basal metabolic charge was a lot decrease than what they began with as a result of they misplaced most of their muscle mass.
So, once they went again to their regular lives and stayed on a lowered calorie routine, they nonetheless regained all of their weight, they usually have been devastated. They stated how is that this attainable?
Effectively, in fact, what do you anticipate? Your basal metabolic charge went down by 50%. So, except you keep on this severely restricted-calorie weight loss plan, you’ll regain all of these kilos.
So, the principle factor is, preserve muscle mass, prohibit a bit little bit of your dietary consumption, and do not overshoot with the lipolysis. Each time you stress your self, you are going to enhance the speed of lipolysis. And if you happen to float an excessive amount of fats into the bloodstream, you’ll shut down the glucose oxidation, which is able to contribute to the lactic acid and all the opposite downstream results talked about.”
Not All Carbs Are Created Equal
When most individuals hear it’s OK to eat carbs, they suppose it’s an invite to eat bread, pasta and processed meals and snacks. Nothing might be farther from the reality. In case your fats consumption is over 30% and also you throw junk carbs on there, you are going to disrupt your lipoprotein profiles and enhance your threat for coronary heart illness, since you’re not metabolizing the carbs and are contributing to endotoxin manufacturing in your giant gut.
You additionally must eat the precise sorts of carbs to keep away from endotoxin manufacturing, which is a significant driver of elevated cortisol and irritation. Excessive-fructose corn syrup (HFCS) is a processed carb that you need to keep away from. Most course of together with any processed meals that use HFCS as a result of it’s so low-cost.
Different carbs to keep away from can be resistant starches from legumes, beans, lentils, most grains, raw potatoes, inexperienced bananas, and pasta. Oatmeal also can trigger bother for a lot of. You’ll understand it’s incompatible with you if you happen to get gasoline and/or constipation, or if it slows your digestion. Oatmeal can be excessive in linoleic acid (LA), which is why I keep away from it.
The very best advanced carbs are ripe fruits that develop in tropical situations, equivalent to oranges, tangerines, mango, pineapple (maintain consumption average because it comprises serotonin), melon, watermelon and grapes. Cooked starches equivalent to potatoes and white rice are additionally acceptable. Potatoes comprise oxalates, which could be problematic, however oxalates are water-soluble, so most might be radically lowered if you happen to boil the potatoes.
In case you have small intestinal bacterial overgrowth (SIBO), you might must keep away from starches like rice and potatoes, as you have got inhibited potential to interrupt down the starch into glucose. In consequence, these sorts of starches could impede your restoration.
Incorporating Train for Optimum Outcomes
The older you get, the extra vital your muscle mass turns into. Not solely are robust muscle groups a requirement for mobility, steadiness, and the flexibility to stay independently, however having reserve muscle mass will even enhance your possibilities of survival3 when sick or hospitalized.
Muscle is misplaced way more simply and faster than it is constructed, so discovering methods to repeatedly promote and preserve your muscle mass is essential, particularly as you grow old.
Age-related lack of muscle mass is called sarcopenia, and if you happen to do not do something to cease it you possibly can anticipate to lose about 15% of your muscle mass between your 30s and your 80s.4 An estimated 10% to 25% of seniors beneath the age of 70 have sarcopenia and as many as half these over the age of 80 are impaired with it.5
Whereas declines in muscle mass and energy are comparatively well-synchronized within the 35- to 40-year-old group, energy dramatically drops off as you get into the 75-year-old and over teams, with 85-year-olds often seeing dramatic declines in energy and performance relative to the decline in muscle measurement.
Blood Stream Restriction Coaching
One of many causes I am so obsessed with blood move restriction (BFR) coaching is as a result of it has the flexibility to forestall and extensively deal with sarcopenia like no different kind of coaching.
There are a number of the reason why BFR is way superior to standard sorts of resistance coaching within the aged. Importantly, it means that you can use very gentle weights, which makes it appropriate for the aged and those that are already frail or recovering from an harm. And, because you’re utilizing very gentle weights, you do not harm the muscle and due to this fact need not get better as lengthy.
I’m additionally an enormous fan of strolling on the seaside and usually go day-after-day for about an hour. I additionally use the sauna and do focused stretching day by day.

To be taught extra, make sure to hearken to the whole interview, and maintain your eyes peeled for Half 2, which is able to observe shortly. Additionally take a look at Georgi’s weblog at www.haidut.me or observe him on Twitter. He additionally has a whole bunch of movies on YouTube on a plethora of subjects.
