- 🎧 Podcast episode 56 with Professor Bart Kay 📽
We discuss gluconeogenesis and how it works, the best fuel for athletes & the optimal nutrition for humans.
Professor Bart joins us to break down the science as to how humans can function perfectly well, and indeed optimally, without consuming 1 single gram of carbohydrates ever.
We also look into why calories are not a good measure in any kind of nutrition, and why 100% carnivore is better than animal based with reference to the randle cycle.

Dr Berry and Salidino recently debated carnivore vs carnivore with fruit and honey because supposedly they are oxylate free. I fell for it and briefly brought back honey. After 4 days a tooth ache came back I’d forgotten. That was all the proof I needed. Carnivore for life now. ; )
I don't remember the Oxylate-free part of the discussion. Especially because many fruits are high in Oxylate. But same! I have somethings sweetened with honey for Thanksgiving and all my finger and toe neuropathies came back. My foot pain is mostly gone now, but my fingers are still very reactive.
Your veins so clogged from plaque that even a spec of sugar can get clogged easily, wow.
I dive on fruit and honey too. Took me 20 days to get really sick. Allergies, herpes, rhinitis cause I couldn't eat enough. I was always hungry. I stopped, came back to meat. One day the herpes was healed. Two days allergies were gone. I think carnivore suits more my gut which is not very health these days, cause I made for a long time a trash keto, like, with diet coke, chocolate, dairy. Another thing I noticed is that I can't fast on carnivore or my body gets stressed and allergies flare up. That's the reason I tried fruits. To add more calories. But now I just eat more and more frequently and all is good.
I tried honey. It triggered my food cravings to come back. It awoke the carb craving pathogen that’s lurking in my gut. Maple syrup kinda does the same to me but not as bad as honey.
@@swyllie30 the only good thing that happened eating fruit is that my mind totally forgot about other stuff like pizza, etc. I don't crave nothing anymore. And when doing, I wasn't craving other stuff, just fruit. But it is an energetic rollercoaster and because of this much more easier to get sick (for me).
This showed up on my feed because I watch a lot of Bart Kay's videos - and I'm glad it did. Cool discussion. Cheers 👍.
I did my change in 6 months. Slowly scaling down the carbs. I never had any negative effects on my performance. I strength lift and run. Now I am very close to carnivore and I can tell you, because I register everything I do and eat, my performance has imrpoved markedly and my waist has slimmed down. I lift heavier at the gym and eat less. As I eat more and more carnivore I eat till I'm full, thus I intermittent fast without thinking about it. My hunger signals now work. It is crazy what carbs do for your body. They actually makes you over consume food. Always having that extra fat on your body. But not any more. 😊
They call it floundering with animals. Same happens to us. Keep eating yet don’t get satisfied. Bloat and die.
Prof Bart...is the smartest man in all aspects of nutrition period
Triple Whammy. 1: N14-15. 2: Gluconeogenesis 3: Randle Cycle. Fact check that! Case closed.
Great stuff. A very well rounded conversation. Stayed to the end Ha ha ha!
I tend to believe this as well. I have been on a meat based low carb diet for 39 years in an attempt to gain weight and ended up growing tall but staying skinny. Just like Bart I can go for months straight without eating a single plant part. Have yet to experience bad effects from it.
Awesome 👍
Lol you will feel the effects of only eating meat, I can’t believe people actually listen to this absolute disgrace of a man 🤦🏻♂️
@Asura Will be 55 in june.
excellent interwiev, very good questions asked
Great interview!
Come for a chat Dave?
@@humannutritionlifestyle Sure thing! I'll mail you!
Gluconeogenesis. Without carbs, my glucose level is 80 to 90 all day with a big dawn effect spike every morning. Your body definitely makes all the glucose it needs very quickly, that's for sure
Me too. If you are concerned with your AM BG see Dr Nadir Ali's video on what can happen if some people eat too much fat even if low carb. My morning gluconeogenesis and TG level improved dramatically by eating less fat, ironically, by going from keto to carnivore.
Typical pattern of cortisol induced gluconeogenesis.. Which likely indicated your cortisol Is also quite high during the night. Which would not be good for deep sleep ? How is your sleep?
@@oskaredwall7662 1.5 to 1.75 hrs deep sleep each night. 95 percent below resting heart rate. 7 to 7.5 hrs sleep total. According to my fitbit. No noticeable sleep problems. When I exercise in the evening, glucose spike is barely at 100. Cardio is definitely the key I needed for that last 5 percent of wellness. 95 percent wad diet. Who knew?
@@petercyr3508 cool. I am doing Carnivore Month in January with a group of coworkers. I will see
@@oskaredwall7662 Sleep good, but I have been thinking the same thing about myself. My BG is very sensitive to stress. My carnivore labs were A1C 5.0 vs 5.6 on keto and my TG way down to 74 from 140. This because I found it easy to cut out dairy. The only fat I get comes from the meat and eggs. It will be interesting to see if my TG stays low even if my A1C is not ideal on my "low fat" carnivore diet. I think I need to get my doctor (yes, Dr Ali) to rule out cushings or some such.
Good video. You have a new subscriber now.
Thanks Bart for clarifying the transition period. I’m battling really bad, all my workouts and mountain biking has taken a SEVERE tank and was really questioning wether I should stick to carnivore. But after your explanation im sticking to it no matter what. Can’t wait to get those performance gains 💪🏻👌🏻👍🏻
Thank you RUclips algorithm for putting this video on my home screen. Excellent discussion. Two very smart guys who understand human nutrition.
I know right! It's almost like RUclips now want to promote Bart instead of suppress.
+1
For the YT algorithm 😊
Just subbed
Good luck w your new channel
Going over some of your content and guests
Definitely on a great start!!
I turned to a Breatharian 5 years ago saved a lot of money.. Only water and Sun much better
As an older adult approaching 60, maintaining skeletal mussel is a priority for me. Would breaking up the protein intake to two meals in the day be beneficial? Or stick with one meal a day?
Either would be fine, as long as you get a good amount of daily protein & essential fats, this will help you to maintain skeletal muscle, alongside daily strength exercises 👍
Great video Matt.
This was a cool discussion. I've also had Bart on my channel 😁
Great work 💪🏼 💪🏼
Excellent information.
I like the dirty channel! 😂❤
Meat contains a few percentages of carbs too...
What i learned is that cortisol is responsible for elevated gluconeogenesis and that it doesn't discriminate between muscle and dietary protein. (Such as muscle wasting disease a.k.a diabetes was cured with 3/4 pounds of white sugar added to their diet of beef and beef broth, in the early 1900s.)..
I'm not doing carnivore because don't think it's optimal for humans. But I'd love to lose that discussion and if I do... definitely I'd try it agaain.. Right now I'm doing milk, honey, starch and fruit.to avoid elevated gluconeogenesis and enhance my metabolism.. i feel good.
The beginning is a bit hard to understand and I watch Bart every day. But the jif is easy
I’ve been 1,5 years 100% carnivore…
Muscles feel like crap without carbs
The not breaking down protein. Is it because of autophagy that people think you loss muscle when really you’re body is removing damaged tissues?
Two different processes here.
Autophagy is cleaning out dead or poorly cells when extended fasting, not breaking down muscle or protein, only dead or redundant body cells.
Protein isn't used as energy whilst fat and glucose are present, (which should be always).
When you are not eating for a excessive long period or have too little energy (fat) within your nutrition, the body will utilise amino acids for energy, but only very sparingly! And only in very extreme circumstances will the body begin to breakdown muscle tissue for energy, i.e starvation. Fasting is not and should never be starvation.
@@humannutritionlifestyle Is it accurate to say that when shifting to and maintaining a carnivore diet, muscles lose sarcoplasm since the loss of muscle glycogen also causes the loss of water stored in the muscle? Is this the supposed intramuscular fat that some say we lose? Does gluconeogenesis eventually help to keep muscle glycogen higher?
@@2old4allthis muscles only lose sarcoplasm in the very extreme circumstances, as long as you eat adequate protein this won't be an issue. Yes gluconeogenesis and regular muscle training helps to keep not only glycogen but also readily available energy like fat higher for faster muscle utilisation.
Whatever the truth might be I just know that when working as a mover I feel better when carb fueled. Its probably possible to train the body to go without but I noticed a definite weight loss on pure carnivore.
As a skinny guy wanting to get bigger and stronger carnivore seems like a bad option.
I'm 178cm/63kg will never let myself go below the 60kg mark.
People that go carnivore probably have some health issues, like leaky gut which can cause a series of auto imune diseases, or need to lose fat, or are pre diabetic. If you fell ok on a standard diet, ok. Just remember as you age you will start to feel some strange stuff going on your body and probably carnivore can be a healing tool.
Carnivore will make you bigger and stronger than any other diet. At least if we're talking muscle composition you can look big and jacked on carbs but you'll have a lot of fat in your muscle so you more look big than actually are big with muscle when i was a carb burner i gained like 20 pounds of "muscle" in a couple months. I stopped eating carbs and lost all the "muscle". I then became a fat burner gained 15 pounds of muscle back and havent worked out in months since and havent lost any muscle. Dont be big from stuffing your muscles with sugar. Make them big by stuffing them with protien you'll get bigger stronger and be healthier then you ever would be on carbs
Isn’t Gluconeogenesis a stress on body? Wouldn’t it be easier to just consume some healthy carbs for glucose?
A constant glycolitic state is stress, gluconeogenesis is the normal regulated stressless state. What are healthy carbs 🤔
It is just eat enough meat and fats. If on a caloric deficit, any diet can be very detrimental. Took me long to understand this. Now I add fat on my meat, eat more meals a day and everything was fine. I was on a deficit cause I usually to eat two times a day and wasn't sable to eat so much.
No such thing as a healthy carb!
As a performance seeker cannt wait 26 seconds not 26 weeks sorry - honey helps
Then you will never find peak performance or, perhaps more importantly, long-term health!
"Calories in - Calories out" assumes many fallacies, for example.
1) It would require humans to be adiabatic, with the ONLY energy release coming from work. Foolish! Breathing alone heats a full breath of air from ambient to body temperature, plus the latent heat of evaporation as we raise the moisture in that air from ambient humidity to 100%, every single time we breath.
2) It would require there to be ZERO chemical energy in our excrement. People all over the world burn poop for heat, and urine of full of ammonia.
Hes not a professor anywhere 😆
He was hence the title
@@anthonyborthwick2401 no he is a fraud
@@flash3047Tell me why he is a fraud? I experienced nothing but benefits from cutting out carbs. Lost 45 lbs of fat and still going. Like he says if he is a fraud SPECIFY something that is incorrect, you 🤡
@@flash3047prove it...
Bart Kay sounds like Durian Rider, voice wise.
Show me the science that says gluconeogenesis choose fat tissue first please
It's simple biochemistry. The body is always trying to be as efficient as possible. Trying to get energy without using it. Fat releases lots of energy without using much to break it down, whereas you can get lots of energy from protein but it also uses lots of ATP energy to break it down, therefore Fat is more favourable 👍
@@humannutritionlifestyle lots of assumption on human physiology in that statement. You are basically saying because it would be preferable in your logical thinking. Therefore it should be that we evolved like that. And therefore it is so. Which is the opposite of scientific theory. More like boy guessing. I'd like to know if you seen the studies that show people who fast from carbohydrate actually don't upregulate gluconeogenesis through cortisol and protein breakdown.. i don't buy it. If you first make the assumption that the carnivore style of eating is the way humans thrive then it's a good hypothesis. But if we look at the data we have on activating the stress cortisol adrenaline driven system through lchf diets Vs hc diets. The data so far show that cortisol is upregulated in the lchf diet.. so if we rather make the hypothesis that the carnivore diet is inducing a stressed state as indicated by similar diets. Then we can ask perhaps what would be most beneficial for a stressed organism. I'd argue to release energy however it can . Since stressed state of physiology should only be transient. But can become chronic. Most of us know by now tjat the chronic stress is a major cause of metabolic dysfunction... Further adding stressors like carn restriction. Might not be the beneficial mechanism of action in the carnivores improving their health.. but rather getting adequate fat and protein maybe for the first time in their life.
Just eat enough meat and fats. Look at the traditional inuits. They are lean health and strong. You won't die if you eat enough meat and fats
@@viniciusmagrinCan carnivores please stop using the Inuit as proof as I’m embarrassed for you. Please do your research ie. the Inuits live 20% shorter lives and have similar rates CVD when compared to their non-native Canadian counterparts. If carnivores aspire to live some 15 or so years shorter lives then ok I understand and buy your story 🤷
@@888jucu yes we know that. I personally don't care. I tell you why. If for whatever reason their life expectancy is lower, now that they are eating a standard diet, they are facing problems that they don't even know exist like diabetes, high blood pressure and all the diseases that now we are relating to metabolic diseases. So now that they are been cultured, their life expectancy increased cause now they have access to more technology? but on cost of their health. Say that western live longer because are healthier, is incorrect. Maybe we have antibiotics and other stuff that these guys don't have access. I made lots of experimentation on myself cause the data is so contradictory. Carnivore makes sense for addressing my health problems that no MD could handle without lots of medicine. I had low blood sugar, gerd. I controlled my hunger and my weight. Thats evidence enough for me. Thanks.
What diplomas does he have? He NEVER mentions that. NEVER.
He does. He mentions his qualifications and certifications in probably more than one video on his channel. He has quite a few.
If you ever cared to watch and figure it out before spewing ignorance... lol
@@slumpedmage Show me a video where he says he has a Bachelors degree, a masters degree or a Ph. D. Go ahead. Good luck.
@maximusdecimusmeridius4040
Don't remember if those are any of them... but he is well qualified. And if you listen to him, you'll see he is educated and has a very clear understanding of the intrinsic metabolic pathways and such, ALL backed with SOLID science. He resents shoddy epidemiology. He knows how to read, if you will. It's a no bullshit, very straight-to-the-point type of lecturing. (Aside from the beefing he gets into) The way it should be on anything informational. He knows his stuff. He wouldn't be that cocky and straightforward if he didn't. 🤜
Sure, you can run a petformance car on pump gas, but if you're an "athlete" and you forego carbs your performance will suffer and you will be at a competitive disadvantage. Not needing carbs for energy isn't the same as not needing carbs for performance.
Wrong. I'm an endurance athlete and perform just as well without carbs. Your statement is true for all those people who are yet to become fat adapted and still rely on carbs. Once you are truly in tune with gluconeogenesis, exogenous carbohydrates are not needed for performance. Sure a good amount of energy is needed for performance, but not carbs!!
@Human Nutrition & Lifestyle physiologically this is incomplete. After the first few minutes of elevated heart rate the body used fewer carbs for energy and more fat/ protein, so the impact on an endurance athlete is less significant after the first few minutes. I've experienced this myself on the bike. But for activities that require explosive movement followed by periods of rest like strength training, basketball, football, etc your body will always perform better if carbs are available to power those movements. I've been fat adapted a while now and I still cannot do as many sets with weights as I did when I was on a low-moderate, but not ketogenic diet and I do better weight training if I do it AFTER a day of carb loading though my performance on the bike is little effected by carb loading. In conclusion, if you want to perform your best cycle in quality carbs, it won't hurt your diet or health but will almost certainly improve your performance (and probably your body comp).
@@leroybrown9143 I won't disagree too much with that final conclusion, if thats what works for you. However if you train with carbs, you will always perform better with carbs. If you spend time specifically adapting your training without, you will then perform just as well without. Your body can give you all the carbohydrates you need, if you let it, by specific training and nutrition adaptations.
@Human Nutrition & Lifestyle I object only to the, "just as well," part of your statement. I think athletes will perform better via glycogen metabolism than they will via glucogenesis in any activity that requires short burst of energy because that's where the cells will seek energy first, even if you're fat adapted. We agree though that dietary carbs are not required and you can enjoy an efficient metabolism without them. Thank you for the vid and the discussion.
Wrong. I'm a national level amateur bodybuilder and I've achieved tremendous feats, considering my health issues, using a carnivore diet. Not 1 gram of carbs is required. Tried and tested with absolute certainty 😁🏆
Not that LUNATIC again.
I think he’s playing a character…maybe. He seriously said something along the lines that a calorie deficit doesn’t cause weight loss, with his video on Greg Doucette.
@@raulsanchez2610 He is not taken seriously by his peers.
Professor Bart Kray-Kray is Professor Terguson incarnate. He needs to go back to school.
This may a bit off-topic, but I just saw it and wonder what Bart thinks about it, if possible.
Don’t Lift Weights - Lower Them Instead

A new study reports that slowly lowering weights builds and strengthens muscles almost as well as lifting and lowering them, as you would do with a typical rep.
That means, for example, that you could use two hands to lift a dumbbell, then one hand to slowly lower it, while sacrificing little in the way of results. Focusing on the lowering - or the “eccentric” contraction - can lead to a more efficient gym session, Japanese researchers say.
In the study, published in the European Journal of Applied Physiology , researchers divided people into three groups of 14 for a 5-week, twice-weekly comparison.
One group performed dumbbell curls from full extension to about one-quarter of the way up, for 2 seconds up and 2 seconds down, in three sets of 10 reps. Another 14 people performed only the lift portion of the movement (a researcher helped them reset the weight after each rep), and another 14 did only the lowering part of the move.
The group that both lifted and lowered the weights increased the maximum force they could produce on a lift by 18%, and increased the thickness of the biceps muscle by 11%.
The people who only lowered the weights nearly matched that, increasing their maximum force by 14% and muscle size by 10%. The lifting-only group increased their max force by 11%, while muscle size increase was insignificant.
Your muscle fibers work two ways. When you lift a dumbbell from a straight arm up to your shoulder, your biceps muscle is using a “concentric” contraction. As you lower that dumbbell back down, the biceps muscle is working to put the brakes on the descent - that’s called an “eccentric” contraction.
The lifting-plus-lowering group saw the biggest gains because they were pretty much doing twice the number of reps. The lowering-only group made similar improvements in strength and muscle with only half the work.
Study author Masatoshi Nakamura, PhD, a professor at Nishikyushu University in Japan, believes that eccentric muscle contractions produce greater neurological adaptations in the spine and brain than concentric contractions. In other words, your nerves learn to send more of the “pull harder” signal to your muscles.
At the same time, the spring action of a large protein called “titin” in the muscle fibers produces greater force during eccentric contractions while using less energy, and more titin could account for the increase in muscle size, which is called hypertrophy.
“Titin in the muscle fibers could be the best explanation for muscle hypertrophy,” Nakamura says. “However, we believe that other factors, such as neurological adaptations, also play a large role in increasing muscle strength.”
The short range of motion used in the dumbbell curls was an important factor. A 2019 study in the Journal of Strength and Conditioning Research found that a partial range-of-motion triceps exercise produced greater muscle growth than full range-of-motion movements.

Concentration on the eccentric actions of weight lifting is always a good thing. I think the study just proves that most people don't do this. Both concentric & eccentric movements should be used in equal measures to ensure muscle hypertrophy across all muscle groups.
@@humannutritionlifestyle What I get from this is that you should not just let the weight drop after a concentric motion, but slowly let it down, eccentrically. It may cut down your reps, but it seems more important to do both the motions. I prefer to exercise muscles to exhaustion point, by doing the last set using progressively lower weight, until I cannot do even 10 pounds.
