Butter remains a firm solid when refrigerated but softens to a spreadable consistency at room temperature and melts to a thin liquid consistency at 32 to 35 °C (90 to 95 °F). So butter will be liquid in your stomach regardless of its consumption form.

[@Appleblade]

Right. A sensible difference would be whether there is some sort of integument holding fat together in the gut that slows its absorption. Saladino and his Oxford buddy (blanking on his name: EDIT: Tommy Wood) suggested more fat is absorbed quickly in the duodenum when it is processed (like hamburger) than when consumed solid, as in a ribeye. And the early absorption was deleterious, but I don't remember in just what way. In any case, Paul is recently a big booster of eating hamburger, so whatever the deleterious effect, he doesn't fear it much. EDIT again: about an hour in in this video: 'How to not die of chronic disease (aka how to avoid insulin resistance) with Tommy Wood MD, PhD'

I feel like someone who was paid to defend something he doesn't fully believe in wouldn't get so fired up like that. It was probably an ego thing.

Nick, you can also see the effect on a CGM. I'm on a mostly carnivore, "real ketogenic" diet (verified by measuring ketones and not assuming ketosis like a lot of PhDs like to do). I recently tried a CGM and when I had a 1 hour cardio workout in zone 3, my blood sugar was constant. When I did my usual 1 hour cardio followed by 30 minutes of very hard lifting with very little rest, my blood sugar spiked and I felt like fainting. I work out fasted in the morning and only eat once a day at 3:00 p.m.. Bottom line: the lifting of weights had a huge impact on my blood sugar.

[@noah4987]

Liquid rendered fat was definitely problematic for me early on. Eating it cold helped tremendously, so I did that for probably way longer than I needed to. No issues when I reintroduced it. I'm also wondering if early on, we're just not making enough bile to absorb that much liquid fat. Anything in excess is expelled from the system. As we adapt, we make/store more bile, and we can handle it a lot better over time.

[@beefesurient]

[@justinfoster1040]

Could you explain more or give specifics on what Dr. Baker said regarding “solid vs liquid” fats? Since he seemingly gave examples of “ribeye/butter” vs olive oil, it seems more like he was talking about eating fats that are solid at room temp, not just eating them when it is in a liquid state(melted butter) vs solid (cold butter). I honestly couldn’t imagine the temperate the fat is when you eat it is going to at all affect your absorption of it/the rate it passes through, since once in your stomach it should rapidly get to to your internal body temperature. AFAIK your body simply needs time to adjust to the likely huge decrease in fiber and carbohydrates intake that comes with going carnivore, at least from 99% of other ways of eating. I know bathroom (and gas) experience is much better and healthier the closer I am to full carnivore.

[@aprilek6003]

I couldn't stop smiling watching this video Nick. Those of us who have been eating this way for years are no longer shocked at just how much we eat and how lean we remain. About your butter experiment, I know you wanted to keep the fat the same but I think Shawn may be on to something with a true polyunsat fat (0live/avocado)verses a satfat (butter/tallow) on rate of movement thru the GI tract and stool consistency.

How ironic that in our age of supposed advancement, we've strayed further from the natural order, feeding on corporate invention rather than the primal sustenance that once forged empires."

I transitioned really slowly more by just the way things went rather than an intention to be mostly carnivore. Never had an issue with electrolytes, any symptom of keto flu, or diarrhea. I stopped cooking with butter because I didn't like the way it burns. I now use tallow and ghee for cooking and maybe a slice of butter with some meals.

[@azarialr6639]

I use a combination of tallow and butter, as mixing them raises butters burn or smoke point allowing me to keep the butter flavour. And I agree that if you are able to moderate a slow transition is easier on the body. I did a slow transition as well, I’m about 95% now, but had already given up breads and cereals for over a year and never drank sugary drinks, so I didn’t have the level of cravings many others seem to experience as a result of me already breaking those addictions making a transition possible.

I'm not surprised that changing the state of fat intake didn't change for you. You've been keto for long enough that your intestinal biota, liver, and lymphatic system are optimized for handling lipids. (The second-most important function of the lymphatic system is its absorption of fats and fat-soluble vitamins from the digestive system, then transporting those to the points at which the lymphatic system "dumps" into the veins. The fat-content of lymphatic fluid is a major characteristic distinguishing it from blood plasma.)

[@jmilz28]

Been a carnivore lifter for 15 months, happy to help in any way I can. Secondly, your body thermally regulated the butter to the same state by the time it hit your GI tract, regardless of the state when it hit your pie hole. You would need to try several different fats that had different states at ~98.6 to get what you're after. From my experience, just dial the fat content up or down as dictated by stool consistency. Just make sure you don't have allergies at the time, the drainage will throw things off.

[@RichardAMorris]

Butter melts at 32C, so liquid and solid butter will likely be liquid at human body temperature. Try adipose fat (tallow) versus milk fat (butter). The longer chained palmitic (25%), stearic (19%), and oleic (36%) fatty acids in adipose triglycerides should be more likely to be solid at body temp than triglycerides in milk made predominately from C:4:0 - C14:0 short and medium chained fatty acids (20%), palmitic (22%), stearic (10%) Oleic (37%). Beef tallow's melting point is right around human body temperature. If you want to push the hypothesis, try mutton tallow, which has a melting point of around 45C.

[@nicknorwitzPhD]

Yes, but it takes time to melt... all dietary fat will liquify and emulsify in the body, and the issue is controlling for FA composition. Tallow isn't free adipose tissue though... there's more matrix in the latter and Tallow is also liquid in the body... even mutton tallow will be liquid in the stomach.

I'm 65 a carnivore most of the time. I was diagnosed with diverticulosis in my 20's (and probably it was there before - I'm a Baker's baby born 2 months prem) and was also diagnosed in my late 40's with a 2cm gallstone, in my 50's with a degrading GB wall (I would love to have an ultrasound to see what's happening now). Anyway, this dietary pattern causes no GB pain and I have next to no bloading. It's taken me about a year to work out I need a lot more fat (butter, ghee, tallow, fat trimmings) to stop straining at stool (we probably need a new stool chart for carnivores esp. regarding volume and frequency). Initially, I took high-dose lipase enzymes as a precaution but I really do not need them and now take a protease digestive enzyme when I'm stressed to prevent any reflux. Too much water, I find can impede my digestion. I recently took part in a new gut microbiome test trial. Very high akkamansia, next to no lactobacillus and bifido. I have noticed if I eat fermented foods - kimchi etc. I bloat dramatically, suspecting too big a challenge to the now resident profile of strains (happy to share the test results with you). I'm also reminded that concerning individuality, Roger J Williams (the father of biochemical individuality) speaks to the different sizes and positions of stomachs and other organs and how this impacts the production and amounts of secretions - stomach acid, bile, and digestive enzymes a person will secrete and transit time. We are all an n=1 experiment and it is always interesting to hear other's experiences, as you say 'context and nuance'.

In my experience loose stools are caused by eating too much fat and constipation is caused by eating too little fat. Simply adjusting total fat intake until the desired consistency is reached worked for me.

Eating solid vs. liquid fats work to partialy prevent runy stool, but not very much in case of butter. I've tested beef tallow instead of butter. It seems it works better than any liquid fat. I would estimate, melting point of tallow is higher than any other fats. But neverthelles in my case everything resolved within a week or two. But before I was on very low carb more than 5 years, so no big change. Except now I feel way more warm which I appreciate, when I realize I was contantly freezing to death.

[@davidrosen2869]

Very interesting and insightful video, keep up the good work! I want to share a few thoughts on some of the scientific points (all with good will of course, regardless if they sound critical) 1. I think I recognize the metabolic advantage paper you show and if I recall correctly, they assume an RER of 0.85 in the DLW method they use to estimate energy expenditure. This is troublesome for a keto study because keto will put one's RER much closer to 0.70. That being said, I believe there was a meta-analysis on metabolic wared studies showing a low carb metabolic advantage, so your main point still holds either way. 2. I could be mistaken, but I believe the lumen only measures CO2, and then it infers RER based on some kind of inference of O2. If this is correct, it adds to your point about not over-interpreting lumen measurements. 3. Speaking of measuring fat adaptation, it turns out that the cheap breath sensors that measure alcohol are also sensitive to ketones. I believe some places are selling such breath sensor now to measure ketones. (The last one I bought was from Walmart).

[@sadrien]

Typically drinking less or no water with meals works for most people with diarrhea issues. Eating smaller meals often also helps. It's probably caused by excess motility and weak bile acids, which are both exacerbated by water over-consumption which dilutes stomach acid and bile salts in the small intestine.

[@jimbrogan9835]

I've heard it suggested, and this seems to be true based on my own experience, that as the body adjusts to a higher fat diet it gets better at absorbing the fats, so that solid or liquid becomes less relevant. Ten months into my current carnivore diet I drink liquid fats in the form of melted tallow all the time with no side effects. I even feel the need to increase my fat intake. Interested in hearing what other people have experienced along these lines.

[@azarialr6639]

I agree. I had a meal at a smokehouse where you can order meat by the 1/2lb as long as you can handle light seasoning on the outside of the slab of meat, and the first time I did an OMAD there I had an unhappy tummy as I was only on a Ketovore/Carnivore way of eating a week or two. Now 3-4months later I can eat that same meal, I’ve even eaten more fatty meat in one sitting, with zero ill effect.

I eat tons of animal fat (only animal fats) and thought it was I was eating too much and having very loose stools (after listening to Anthony Chaffee. I was paleo/keto 14 yrs now carnivore for 3yrs. But somewhere I read/heard here on youtube that the issue might have been I was eating too much rendered animal fat in liquid form. For instance I have homemade bone broth everyday and when I have cooked some very fatty meat which is everyday I would drain the rendered fat and juices into my bone broth and drink it the next day as part of my broth. So now I still add the fat but now I let it solidify and then remove it before warming my broth and it worked. So my fat just comes on the meat. I think this info may have originated with Shawn Baker, something along the lines of rendered fat and butter are very concentrated. Also I render my own beef fat and love the crunchy bits that are left at the end, twice I ate a whole heap of these bits and I had extremely explosive diarrhea. So I know only to eat a bit of it at time. I know this isn't liquid fat but it is rendered fat.

[@carnivorewhisperer5823]

Eddie likely needs to read up on gluconeogenesis. On a fat and protein only diet, or with very low carb, during a hard workout such as Eddie's or Dr. Baker's, gluconeogenesis will convert fat and/or protein to glucose. It does the same in a fight or flight situation. Your body will give you quick energy (using gluconeogenesis) so it is available in those situations. You are burning a lot of energy if you work out as hard as those two guys so your body compensates to give you the energy it needs. That's why glucose can be up a bit higher afterwards. A nice walk will generally bring it back down.

It seems this issue varies depending on the person, and also tends to be less of a problem over time as a person's body becomes more fat-adapted.

Hi Nick, really enjoy your videos. Wondering if you could do one about the Randle cycle. Tried listening to Bart Kay, but don't like his 'attitude' and struggle to fully understand it, also he is very much 'carnivore' I feel he is somewhat biased, would welcome your honest explanation :)

[@todance2]

you have a mistake in the poster. pyruvate is not a 3 glucose chain molecule but a 3 CARBON molecule. regarding your experiment as i see it Shane Bakers theory is talking about fats being liquid and solid at room temperature and not liquefied vs unliquefied fats

[@SteveMark-v9w]

Recently found your videos - good stuff. On this one, wouldn't the solid/liquid fats experiment, wouldn't liquid butter and solid butter really be the same, since they would both be in the same state at the temperature inside your body? So to do the comparison, you would need to choose something that is liquid at room temperature, such as olive oil. Were the fats Eddie was eating poly, mono, or saturated when he was having the troubles? It would seem like if they were poly, perhaps his body was trying to protect him from excessive - ? Or maybe it was insufficient bile to digest it? I have had friends of mine who have had their gall bladder removed tell me that sometimes if they eat something that doesn't agree with them, it just goes right through them.

[@AlexP-oc9yq]

What about stearic acid (cocoa extract) as solid fat to experiment with? Like the croissant diet by Brad Marshall which proved effective in shredding. If I remember well he explains with physiologic metabolism.

Dr. Anthony Chafee helped me with loose stools. He said it could be one of the 3 things causing loose stools, eating too much fat, drinking too much water or something that has an artificial sweetener included in the ingredients. My issue was an electrolyte supplement had stevia in it. I stopped the supplement and my stools are normal or type 4 according to the Bristol stool chart

I think one think people don't realize is even if you take the established "kalorie" science and estimate how much you would use during exercise, its estimated to be less than 100 calories per mile, for what most would consider fairly strenous exercise. Iron man athletes use estimated 11,000 kcal a day, Eddie doesn't do anything even remotely as intensive as that. I also think its worth mentioning, there is the assumption that we must absorb all the food we eat, this appears to be false, the transporters in the gut that absorb nutrients are actively controlled, your body can _choose_ to not absorb food. So, how interesting it is, when you talk about "fat malabsorption" in the context of deliberately overeating fat. :))

[@Mallchad]

PS. I read that over 50% of fecal matter can be bacterial mass, which would also answer the question of "why can I drown myself in sugar and not get diabeetes", well, like having a tapeworm, you have help. I also never get runny stools from lots of liquid fat. It seems, for me, my body would rather throw up before I can even test that theory, but considering some days I eat quite literally only cream and butter, I think I can rule that out

I only eat raw beef and there are no shits problems. I've tried eggs, butter, cheese, as experiments and I started off cooking the meat, just not like Mom told me, which caused it to be black before it was edible according to her standards. What I've noticed is that raw tastes the best and doesn't require salting like it did when I was cooking it. Butter doesn't cause me any issues. Eggs seem fine also, but since I cannot get carnivorous chickens I figure I will just avoid them until we start raising chickens properly on worms and bugs. Cheese I find addicting, so I've dropped it and it did cause me to have weird problems with shits which I tried to work out with magnesium and that just causes other shitty problems. So, butter seems okay, but beef alone and raw, is absolutely perfect. Can't get any cleaner than that. Just amazing. Never imagined I wouldn't need any fruits, plants, nuts, etc nor any toothpaste, nor even shampoo. Can wash yourself with an egg and eat raw beef, without wasting any energy on cooking. Just crazy what a 180º change this has been and too fix all the pain problems, dental health problems, and more. Great experience.

I was actually so happy to get the sh****ts my first 2 weeks. Every time I went to the bathroom, I felt lighter and less bloated. I'm so happy I'm not full of it anymore lol. I have done a fat experiment where I ate nothing but butter sauce and pork belly and ate a whole block of raw cheddar. Both days I lost weight the next morning but had to use the bathroom alot. Dr Chaffee and Berry always say "only some fat is absorbed, the rest will come out. If you use the bathroom too much you are eating too much fat" I only go to the bathroom twice a week now. Gained 10lbs but lost 3 inches off my waist (before finally losing 20lbs) and my legs look amazing. After years of keto I was still storing fat in my let's and lower belly and I was only measuring those areas, but to my surprise, my cup size went from b to c in 3 months. My face looks different (maybe from all the chewing or better bone/fat density .. who knows?) Acne cleared up, and period pain has decreased tremendously. I feel like an energizer bunny so much so it kinda affected my relationship a little at first.

The human digestive system can't process raw meat because it's longer than carnivores, and it's not acid enough to break down raw meat. Hence, it has to be cooked. Also, eating only meat without enough fibres to help process it has to do with the stool problems.

The difference is significant when following a strict Carniovore lifestyle. Only a few are capable of it, because they are addicted to sugars, caffeine, or Casomorphins. Casomorphins in dairy products cause the backflow of food in the intestines, i.e. constipation (ruminant food). In addition, they cause fatigue and the industrial casein in milk (pasteurized) blocks the microvilli of the small intestine and prevents the absorption of nutrients. Coffee alone spoils Carniovore, everyone should familiarize themselves with the mechanisms of action of Coffee and caffeine (Cortisol/Catabolism/Deficiency of Minerals). In a pure carniovore, adaptation takes about two years, only then are all the harmful intestinal spore bacteria completely destroyed. In pure Carniovore, about 80% of the food is absorbed and in children 90%.

I've been on keto for years with varying results on weight loss but I had to stop it because of gallbladder/liver discomfort that I absolutely could not resolve. Do you have any videos explaining what happened and how to avoid this?

No 1 would be to do an ultrasound and check the gall bladder for stones and infections (like the liver fluke). Then, I’d proceed to improve bile flow and amount- regular use of pleasantly hot water, lecithin, taurine, artichoke etc. Fat in keto demands good bile flow to absorb it and can highlight underlying issues.

Solid butter will instantly liquify when it reaches your core body temperature. Solid fats like the fat around a steak are broken down and released much more slowly into your small intestine.

Dr. Anthony Chaffees has a different theory from Baker about fat and stool. I tend to believe he is right, based on my own experience. On a meat heavy diet, if you don`t eat enough fat, you will get hard and possibly painful stools. If you eat too much fat, you get soft runny stools. It`s up to you to find the balance that works for you. He explains it better than me. Check out his talks about that. Nick, it`d be interesting if you could update what you said here, based on self experimentation of Chaffee`s theory vs Baker`s.

[@CashMoneyMoore]

I can certainly have "soft stool" when drinking too much MCT oil, vs having a similar amount of mct but via coconot oil which is a solid at room temp. I do in general think that beef trimmings would be less likely to cause diarrhea than olive oil or drinking butter. You could maybe experiment with liquid tallow vs beef trimmings

I also misunderstood the experiment initially, on similar reasoning, but Nick helped me see the point. Perhaps the butter eaten cold remains, for a larger portion of its time in the stomach, as larger, initially semi-solid, globules, compared to the melted butter? I think we all agree that any butter not emulsified would exit the pyloric valve in a liquid state (globules? droplets?) but the question of how quickly the two forms of butter get through is still an interesting one.

RIP Eddie. I am a hunter/fisherman and an elite survivalist so I have had to study what I can put my body through to survive. Short term the gains on the carnivore diet are excellent. Long term however there is damage to the endothelial. The microbiota in the digestive tracts contains 100 trillion microorganisms which require a complex diversity of plant fiber to create a healthy balanced microbiome. This is 80% of our immune function against disease. Unless you were born in the North Pole and come from hundreds of generations that have adapted to go long periods without plant fiber, your life span will be shortened on a carnivore diet. There are no long-term studies anywhere proving otherwise. I love my meat and fish but I also love being 60 years old and sprinting through the bush with my hunting dogs and no health problems because I look aftre my Microbiome by feeding it 30 colourful veg and fruit every week and don't eat rubbish.

How exactly is a diet that totally transformed my health and kept me out of a wheelchair going to kill me early? Nobody understands the microbiome. Anyone who pretends to is lying. A healthy microbiome is one that a healthy person has and that varies widely. The fibre thing is a myth. We don’t need any plants in our diet at all.

[@nickolasvlachos4013]

Perhaps you could entertain an engineer's insight for a moment: maybe the "liquid" vs. "solid" fats question needs to be tested with fats that have different solidification temperatures, not different actual temperatures during ingestion. Granted, you tried to keep the fatty acid content identical in order to vary just one parameter (the material state, at ingestion) but perhaps the effects in question arise due to the physical property differences related to fatty acids' carbon chain length and/or degree of saturation. So, I think Dr Baker's remedy can only be tested with non-identical fats: butter vs. lard, dairy cream (as in the ΦΑΓΕ yogurt) vs. beef fat, etc. Not sure if this should be done in amounts that are equivalent volumetrically (physical consistency of inhomogeneous materials usually correlates with the volume fractions of the constituents), calorically (the usual in meal design) or on a mass basis. And for the volumetric or mass bases, maybe you need to correct for water content, if the experiment fats have any? In the above, I assume that only the fat's physical properties matter, i.e. any cellular matrix that meat fats are embedded in is broken down in digestion. Really appreciate your excellent and highly educational videos.

[@nicknorwitzPhD]

"can only be tested with non-identical fats: butter vs. lard, dairy cream vs. beef fat, etc" -- you see why this doesn't test the liquid/solid question right?

[@nickolasvlachos4013]

@@nicknorwitzPhD Yes ... after going back to revisit your description of the hypothesis, as you discussed with Dr Baker. Forgive me for going off on a tangent (at some point I had shifted the basis of the question 😳) but, imagining the physics of the solid/liquid butter's journey, I got worried that maybe you were not actually testing the hypothesis - though I see now that this was a rushed conclusion. I think what led me astray is the expectation that both forms of butter (the part of them not emulsified first) will be in the same physical state (liquid) at passage though the pyloric valve. At reasonable rates of ingestion and at the butter temperatures you probably had (say, as low as 4 °C if it's straight out of the fridge), we can safely assume that both forms of butter will come close thermal equilibrium with the body by the time they reach the pyloric valve. However, I can imagine a difference, in that the initially cold butter would perhaps remain, for a longer portion of its in-stomach residence time, in larger initially semi-solid globules. Would this slow its passage, as per the hypothesis? Could the degree of contact with emulsifiers (mainly in the stomach?) lead to an antagonistic effect? i.e. the cold butter, with lower surface-to-volume ratio, evading emulsification more? Anyway, I prematurely jumped straight to thinking about the viscosity / melting points of the fatty acids being incorporated in the final composite "product."
