I'm Irish-stubborn, keep my own counsel, don't tell me what I can't do...if only doggedness were monetized 😂 "They call you crazy till you prove them wrong, then they just call you lucky."
Nick, all these experiments that you are documenting and putting out to others is extremely beneficial to everyone. Instead of starving obese people for 14 or 30 days and making ridiculous conclusions, the idea of studying people who Don’t gain weight no matter what they do is going to open up the world of knowledge. It is quite amazing all the things you are willing to do and eat. Thank you.
I find it heartbreaking to see people, mostly women, that are overweight, struggle with all the signs of insulin resistance and they are trying desperately to lose weight - and they say "I eat close to nothing. Oatmeal with skim milk, and banana and an apple + a small glas of orange juice" and of course here everybody knows what a desaster of a breakfast that is - but good luck trying to get them to think of two eggs, bacon in butter and a coffee with heavy cream as the weightloss alternative.. They think you are making a bad joke, bc the TikTok Influencer that said "watch out to not pour to much olive oil on your salad as this is a hidden calorie bomb" never mentioned THIS!
thanks for this!!! I love your open mind and your integrity. I also did the Feldman protocol, just to see what would happen- before my LDL was 310, afterwards my LDL jumped to 524! It shocked me. My triglycerides doubled (still under 100- my tris are usually around 43), and my HDL went from 81 to 89. 1 lb weight gain. Also my heart rate jumped from 57 to 73 and my blood pressure went from 90/54 to 116/72. Overfeeding is REALLY not my friend. I started adding in 40 grams of carbs a day, divided between two meals and my LDL dropped to 180, my tri's back down to 45 and my HDL went back to 81. Interesting sh*t.
All this indicates is that variability between people and the fact that these LDL metrics change so quickly depending on what you eat, there is no way this metric can be used to assess anything. It's just a convenient measurement because it can be done so easily, but to base a whole treatment plan on something so variable makes no sense at all. I don't understand how the statin and decreasing cholesterol theory is still pertinent.
I've used this protocol to reduce my LDL to pass a military medical twice now, it works in just two days of 5,000 calories a day of fats, a third and fourth day reduces it a bit more each day but for me, most of the LDL reduction happened in the first 48 hours. I did have a blood test after two days, then the third and forth day to see the change. Warning! Eating that many calories of pure cream and cheese is not pleasant, OMG, stuffed. Try drinking 1000 ml of heavy cream in one shot, not so fun. Again, my LDL went DOWN, not up, but most important for what I needed was the LDL to HDL ratios went back to the normal range which is what I needed to pass the test, otherwise I was going to have to due a nuclear stress test with heart echocardiogram which I wanted to avoid due to my age, fearing I'd fail it due to being too out of shape. What I did was a CHEAT, but most doctors are clueless this can be done.
Shawn baker did something like this as well…cholesterol is a dynamic measurement, putting people on drugs for a dynamic measurement is complete insanity
@@nicknorwitzPhD talking about dynamic measurements so is your fast glucose this is just a waste of time also. I’m currently using a cgm and it changes depending on exercise, time of the day or carb eating which have only eaten to check things out. My glucose doesn’t change when I eat my normal meal of meat. Which means my glucose level is always a fasting reading except when carbs are introduced. Btw without carbs tit varies from 120-60
I love your nuanced approach. Your honest understanding of what missing data means to the health community, and your recommendations as few and far between as those recommendations are.
I love, absolutely love your approach to explain and modify your existing hypothesis to accommodate this last experiment instead of writing it off as an outlier like has been done by controversial figures in nutrition research. It really seems like you, Feldman, and colleagues are developing are great working theory of human metabolism that's been missing
I tried the Feldman protocol and my LDL went up and my TG went down. I am not lean mass, I am obese. The Feldman protocol obviously does not work for everybody. I could not speculate as to the reasons why. I did not want to tell my GP what I had done and had to argue about refusing statins.
Like you, I'm obese, so I'm saying this as someone with similar experience, not in a negative way. We are obese because we are metabolically unhealthy with chronically high insulin and damaged mitochondria. It's impossible to lose weight until our insulin is low. Our fat cells are already jam packed full. The Feldman protocol is clearly for someone who is metabolically healthy.
Oh, and just wanted to give a tool for talking to your doctor about what is more important, statins or something else (like diet). Here's a link to a video by Dr Ken Berry, "How to NOT DIE from a Heart Attack" ruclips.net/video/BIg8A_i4hhI/видео.html
You are missing the effect of the FADH2:NADH ratio - you might want to read up on the proton series at hyperlipid. Fat is not one thing - but a family of things - each with different effects. We did not evolve to eat high dosages of plant oils. Anyway - the LDL theory of CVD is pretty much dis proven - a better way to look at CVD is as a thrombotic disease - A good place to start is with Kendricks' books. Insulin levels are way more predictive - chronically high insulin as is found in people suffering from T2D. Insulin is not just about blood glucose levels - it shuts down autophagy - reducing the ability to re-absorb blood clots that lead to narrowed arteries.
Hi Nick, this comment is unrelated to the current video but I was wondering if you’d be willing to make a compilation video of sorts on the keto foods/meals you eat in a week. I can’t speak for anyone else but I personally would find that very helpful/interesting. Thank you for taking the time to read this comment.
Thanks for the video! My personal experiment didn’t go so well: it appeared that carnivore plus TRT gives you a heart attack. I’ve been preaching low-carb diets for about 18 years. Last five years I’m on carnivore. And also was abusing PED’s for about 10 years. Now I have my coronary arteries plaqued. I am about to do a surgery. Unfortunately we do not have much data on that the price is too high guys
I don’t know when but some time ago I saw a medical show on TV I think. Anyway what they said was that it was sugar that would scar the interior of the blood vessels and the cholesterol would act as a bandaid filling in the scared part of the blood vessel. Like a scab only it didn’t know when to stop collecting fat cells and therefore clogging the veins. Which in theory might be why you can be low carb high fat and have a health heat? What say you Nick Norwitz?
I have no idea what to think or believe anymore. I’ve eaten meat my entire life and avoided vegetables because they taste like shit. Last few years I’ve been avoiding carbs. I fast a lot because I’m never hungry and not by a conscious decision to starve myself. I seem healthy enough but I really have no idea!
@@Ge1Ri4, Except that the scan for CAC only shows hard (calcified) plaques. Soft plaques not detected by it are less stable and more prone to break loose and cause a clot/blockage. See Dr. Ford Brewer's videos comparing different methods (CIMT, stress test, NIVL Duplex Scan, CAC score) of assessing risks for cardiovascular disease.
At 67, my health and longevity *IS* a crap shoot. They lied to us about the 'dangers' of saturated fat; The disregard for carbohydrates' effect on insulin levels affected my ability to lose weight; The poisoning of my metabolism with industrially processed seed oils which have no place in the human diet; And the messaging by the federal government nutritional guidelines to avoid meat (in itself a religious belief, which makes it un-constitutional IMHO); means that I had to get guidance from RUclips. I believe that this community saved my life. where would you put your money?
so much passion I love your vids helps me stay keto, while almost everybody around me says Im crazy and have dead wish, and one more beautiful thing about keto after a heavy workout next day my muscles are not sore as they used to be when I was thinking that carb are the MAIN fuel for energy, I said sore, what I meant was actually next day I feel stronger and it lasts longer
I'm already lost the plot but here are some possibly related ideas: - Eating that much fat might not get absorbed (bile secretion works as a safety valve), and the increased protein would lead to effectively higher protein ratio which might turn into glucose. - I heard someone mention that cholesterols and plant sterols would affect LDL differently so if you changed your fat sources, things could change. Also, in case of unabsorbed fat, some types of fat could absorb with different priority.
Some variables that might not be accounted for in this experiment. Eating a certain number of calories assumes those calories are all going into the body, there are variables that can change this even in the same person. Going to guess that your GI wasn't too happy and let you know. Also, that change in fiber would impact the microbiome in your gut which would be another variable that would make a difference, guessing trying to get the calories but limiting that fiber increase would change things, especially considering your GI history. You could also have a microbiome vastly different from your "average" person given past history, I think you mentioned having Inflammatory Bowel Disease, CD I think, damage to the gut from that would change how or what gets absorbed along with the potential of having gut bacteria that interacts with food much differently from others. I don't know the types of fats that you ate, but different types of fat absorb more or less depending on their type, the fiber can also change how much gets absorbed. Without being used to eat that many calories or those type of calories I'm not sure what impact that would have, the microbiome and the cells of the gut can change depending on what you eat and likely would take longer to absorb more of what you eat. Finally, there does seem to be impact of what food goes in based upon gut/brain interactions, as you likely have pointed out, we are not a test tube and the biology of our body is much more complex than most realize. Also recommend listening to the recent Huberman podcast where he talks with someone about the Gut/Brain interactions, that added some context to gut things that I hadn't thought about and would likely help you with future experiments involving food.
This is a great response to consider. We are learning more and more about the micro biome and how much it really affects how we respond to food. So it really isn’t so much the calories. It’s what type of food, the makeup of the food, nutrient density and how gut bacteria interact with it. We all know someone who can eat anything and not gain a single lb. Yet some people swear they gain a pound just walking past the bakery.
Yes, we are all similar but not exact. Yes differences in fat cell hyperplasia vs hypertrophy. Be interesting to see the starting triglycerides and ending triglycerides. Fun experience. An open mind is great. Too many find something they feel that works and then stop.
When I removed added saturated fat and cut back on red meat. I used olive oil only after that on whatever I ate and ate mostly seafood, my LDL-C dropped from 360 to 145. On Keto/carnivore diet.
If you ever decide to repeat this experiment, it would be very interesting to know how your insulin levels were affected by the additional food. I’m not sure if someone can significantly expand fat cells without an insulin signal to do so? I’ve had the same suspicions about my response to overeating. I used to eat tons of cheese (and I ignored my mom’s pleas to “at least have some crackers with it”). Sometimes cheese would be my entire dinner. It didn’t result in any fat gain-just things like nervous energy, inability to wind down at night, increased thermogenesis, desire to go for very long walks, etc.
Great point. I guess his weight gain was linked to the protein overeating and thus the extra insulin secretion. Actually, it seems like Nicholas performed the kind of study Dr Benjamin Bikman is calling for to dismantle the calorie hypothesis.
I am like you nick, same frame and build. Always ate close to keto for the last 10 years unintentionally. Now about to move to full keto... Cheers for the breakdown. Your a very clever boy.
@@nicknorwitzPhD have you posted anywhere the breakdown of what you eat daily? Not trying to copy. Have my own stuff l will always eat. Specially makeral and sardines. Always looking for ideas
You should do a video with Miche, Ph.D. She's on the vegan side, but very similar to you regarding testing things and research. You'd hit it off, intellectually, and we audience folks would enjoy (and learn a lot) from your discussions/tests. As a thin vegan who still struggles to keep my blood sugar down, I'm obsessed with insulin. I really do think it's excessive insulin release due to skyrocketing blood sugar that causes fat gain. I mean there's a reason why the average type 2 diabetic put on insulin gains 20 lbs. without eating more food the first year. I've noticed that when I eat low glycemic, I can ingest more calories and not gain weight.
When eating a healthy diet, you are doing little to no damage, requiring you to use cholesterol. Thereby using the cholesterol eaten in the food, was added in to your serum cholesterol. This fits with my theory. When you eat a species specific diet, for humans that would be zero carb, high fat, moderate protein. The number of calories are irrelevant. When I started carnivore, to cure my type 2 diabetes, was eating a diet of 0% carbs, 70% fat, 30% protein. Equaling on average, every day for a month, 5,000 calories. With zero exercise. I lost 60 pounds. Going from 250 to 190 in 30 days.
@@Chaubunagungamaug I have. Glad I did too. Cured my diabetes. Reversed my cancer. The answer to great health, pure health, is simply this. Do not eat plants.
Your passion for science and learning is inspiring! I am hoping that I can participate in similar academic discourse and discovery when I start medical school!
@@nicknorwitzPhD Not confirmed acceptance yet. Taking my MCAT in a few weeks 🤞 . Hoping to attend University of MN. This would be a second career for me!
That is so cool. At 59 I’m not going to try this one, but I did realize my own variability in adding carbohydrates to lower LDL. I needed 200 grams of sourdough bread to achieve your Oreo rate of decrease. 😃 I added about 50 grams a day for two months and barely changed my labs from strict keto LDL 344, HDL 111 and triglycerides 71. Interestingly, my insulin rose in that time from 3.5 to 7.2. I’m slowing down my bio hacking to every 90 days to save money 😃 thanks for a great video Nick
Answering virtually every comment, I have to admire the commitment. And having the capacity to do this in the context of keeping research and med school responsibilities on track. When I was in med school after prepping and eating some real food, keeping myself washed, dressed and fit, the only time left in each day was for about 4 hrs of sleep. I reassured myself at the time it would only be for a short while. It turned out that was the baseline for the next 40 years.
@@nicknorwitzPhD Perhaps I was whining. Rather, I would see it as a near optimal path for me. Some more sleep would give me a few less grey hairs and slightly better metabolic health. But the memories are irreplaceable. I was never able to attend a game or graduation but despite that my 4 children are all in the health care space. Like me they thought I was doing important work and having fun. Don't slow down, I'm just impressed. In 40 years I won't be around to compare notes to see who saved more lives or had more fun.
Thank you for doing your amazing work and being so public and entertaining about it. Great term this LMHR! That used to be called YSSJEM (You So Skinny, Just Eat More) - Im fascinated by all this and for once this community is about skinny people :)
I am glad you added the disclaimer section, I think with the tendency toward polarization that we are living in, it is important to state and restate precisely where you stand and sometimes more importantly, where do you NOT stand. I unfortunately have seen your name used to defend people advising those with actual FH to let their LDL rip as high as possible, stating that they were of the belief that you have FH yourself and are not concerned about it since LDL is good.
You share the facts/results of your experiment with everybody, and then start with your thoughts and explanation 👍. A lot of people don’t do it like that…
I find these n=1 experiments really interesting. Keep going! I switched from Plant based high carb diet to omnivore low carb recently, and have started seeing LMHR signs in blood tests (I've been lean all my life, and last 3 years at at my 15 year lowest weight).
@@nicknorwitzPhD My fiber intake is >20g a day (20-30 I'd say). Fat around 65-70% of calories. BMI = 18,4. It used to be 20,5 before my 3y plant based period 😅 Trying to do more strength exercise and eat what my body asks for without forcing (I'm tired of forcing to gain weight). My plan is to stay low carb, although I do exceptions, and to alternate with some keto periods. I just targeted being in ketosis once and I entered ketosis (I measured), without big effort (staying below 50g carbs). My evolution in 9 months since I changed from Plant based (high carbs low-medium fat) to omnivore (decreasing carbs and increasing fat intake over this period, but still moderate-low carbs when I did my test 3m ago): LDL from 79 to 210; Trigl from 124 to 76; HDL from 36 to 65. I'll get a blood test done soon, will see how it goes now that I've been low carb (with exceptions). Thank you!!
@@nicknorwitzPhD Thanks for your answer. I'd say my fiber intake is >20g (20-30), and 65-70% fat. Why you ask especially for this ratio? My BMI is 18,4 😅. It used to be 20,4 before WFPB diet with normal activity. Now I eat: Vegetables or salad with every meal (2 or 3) (prioritizing low glycemic index), some nuts/seeds.

During that time I : LDL from 79 to 211 HDL from 36 to 65 Trigl from 124 to 76 My plan is to continue low carb with Keto phases, to reassess shortly as I'll get some blood tests done soon. Thank you! Best regards.
Your intelligent, self experimenting fascinates me. I appreciate your willingness to share your personal medical information. Please be careful that you don’t permanently damage your health.
Hi Nick. I just watched a few of your videos and subscribed. I have a question. Do you think the size of your lipid cells could be a factor in your experiment? The reason I ask is because I was told that I have large “fluffy”lipid cells in my blood and not the smaller “sticky “ lipid cells that can clump together……causing plaque formation in the arteries. ( my cholesterol is very high but I have a low blood pressure)
Hey Nick. Interesting results! I recently got my labs done and my LDL continues to climb up to 20.51 (canadian measurement) which translates to 793.12 American measurements. My doctor is freaking out understandably. I'm 65 and 109 lbs and I am very active athletically. I have a zero cac score. Any thoughts? Oh and pretty much Carnivore.
CAC isn't a reliable score, not matter what the Carnivore charlatans tell you. Once you have calcified plaque, you are very, very atherogenic. But, likely you won't listen to science. But, $30 or so, get an APOB test and see where you stand.
I’m a LMHR, went carnivore/low carb 2 years ago. Before that for 3 years my RHR averaged 55 BPM, since starting low carb it’s been averaging 61. I used to struggle with POTS type symptoms but I haven’t since eating 90% meat diet with zero to a few low carb days a week. I feel better and lost weight but wonder why low carb made my RHR go up. Just staying curious!
What would also be interesting is measuring macros' calories against workouts, and energy expenditure- not only for the calorie differential I.e calories consumed versus calories expended during work, but also the amount of work- energy and coenzymes that it takes to digest the macros in question. For example, bile salts are produced by the body to digest fats and it takes the amino acids taurine and/or glycine, used along with cholesterol to conjugate into bile salts. It would be interesting to measure the amount of cholesterol in the food against that used making the bile salts to digesti the amount of fat, whether it's dietary, cholesterol or cholesterol the body is producing. And the total energy expenditure in digestion which is often overlooked. Seems like it would be something measurable through known equations. It helps to understand fat metabolism too which researchers are still working on explaining. Question, were you taking any digestive enzymes with that, like lipase? Would you because of such high fat ingestion put a warning for people with liver, gallbladder and pancreas issues here for the high fat intake? Or would it be certain types of fat more likely to give you problems like cooking oil that has been cooked into foods? Asking for people over the age of 50 who also may have some metabolic/digestive issues, like a tired liver, gallstones etc.
This is similar to the Hadza experiment. Feeding them with SAD. No effect in energy metabolism short term. Nick nows almost nothing about POMC but some about Leptin. That is the key to this.
Have you ever measured how much calories excreted out of your body daily? Some energy balance calculation could shed more lights on what your body utilizes under different contexts. Or is it even possible? Any way to correlate to combustion of intake and excretion mass to intake and outgoing calories?
I've done this as well before prior to certain labs just to test it out. Definitely worked for my cholesterol lowering. Doctor didn't care much, though. I will say whenever I ate so much my temperature will _always_ go up by A LOT. Like I'll be waking up at night in a pool of sweat and so on. My heart rate can as well go from 45-50 resting to a whopping 100 resting heart rate depending on just how much I've eaten the previous day. I don't gain much weight either as my weight will usually drop to below previously measured within a week or two tops, no matter how much I tried to overfeed myself. It's quite interesting. I've done a 10MCal a day for a week experiment before as well, though with processed foods. It didn't end well as I literally couldn't walk by the end, it was wild, but it taught me what ultra porcessed foods do to your body really well. Meanwhile overeating (though less kcal) on a keto-diet had none of thse bad symptoms.
Disclaimer, my not fully understanding the physiology, but I have 2 questions. First one is simple. Was the increase in NEAT due to the thermogenic effect of food? And second, could it be that you appear to be so very lean, that there wasn't enough fat mass to expand? Perhaps comparing to others who have done this (Sioban), Calories per body weight or per kg of fat mass. Might there be an inflection point of overfeeding beyond which LDL would increase rather than decrease? Again, indexed to, say, total body weight or fat mass? Rather than just an increase in energy expenditure.
This raises a new question: why do your compensatory mechanisms engage, and can we cue into this to make it happen more for ourselves. For instance, after a large meal, force yourselve to walk, bike, whatever to expend energy (get more of an interoceptive feeling for when you have energy abundace and make sure to use it)?
"why do your compensatory mechanisms engage, and can we cue into this to make it happen more for ourselves" - very good question and not one with an easy answer...
After a nights cogitation on this, a couple of seemingly obvious hypotheses came to mind all based on making your body practice this: 0) Low carb and insulin diets to tell your body to burn, not store, energy (though stem activation with insulin and abundance of nutrients should be cycled too) 1) High Intensity Interval Training to mobilize huge amounts of energy flow to musculature and metabolism in general, 2) themogenesis by engaging cold and getting your body to energize to keep you warm, 3) fasting to make your body tap into energy stores not normally accessed. In fact, all of these can be used to boost metabolism and probably mitogenesis as well. Practice makes perfect. I've picked the main principle up from Lane's books: life is energy flow. (Luckily, as humans we have the ability to direct how the enery flow is used. ;^)
I'm a lay person so forgive my ignorance. Am I correct in understanding that thr reason the Feldman protocol did not work for Nick was because he raised his energy expenditure ie he was doing more exercise while he was on it than he normally does?
Cashew? You mean macadamia? Probably very little. Sat vs Unsat doesn't appear to impact my LDL-C much w/ my highest LDL-C of all time being when intake was 1:5.67 sat:unsat ratio
Hey, this may sound strange but, have you noticed any changes in your stool consistency, smell, etc, during the 6000kcal diet? Also what is your normal energy intake (before/after the experiment)?
Was there any change in your triglycerides and HDL ? Would be interesting to know, what the trend is (according to your n=1) of the expected response......As per lipid energy model, assuming your LDL went up because of your increased energy expenditure, and as you have been a lean mass hyperresponder, for enough time to reach homeostasis, a mild increase in HDL and mild decrease in triglycerides as well
I understand we are all different, but would love to get more details into your diet and what you think is the best bang for buck calories. What I mean by bang for buck is not the energy calories in the food alone, but the total energy all things considered (i.e. thermic effect of food, etc.) and with all things considered can the difference be significant or negligible. Thank you.
Thanks, my main take away from this is the power of individual variability when making any comparisons even when the population cohort share many attributes such as LMHR. Every individual strives to achieve an optimal homeostasis based on his/her very individual circumstances at any particular time. I would go as far as to say that your individual measurements of bio-markers yield PERFECT RESULTS FOR YOU as an individual regardless of expectations based on averages taken from other population cohorts and especially from general population averages.
@@nicknorwitzPhDMCT was the wrong word to use. Was it the increase in calories from monounsaturated fats is why your metabolism went up? Would your metabolism increased if you consumed saturated fat?
I would be interested to know what your apoB was before and after. I am a LMHR who has given up trying to gain weight. I can eat a million calories a day and I never gain weight. This explains a lot about individual results.My CAC is scheduled soon I am curious about the results of this test also. Thanks for your great work.
Can you do a video on postprandial endotoxemia from a high fat meal? If high fat meals increase LPS in the blood, does that mean high fat meals increase inflammation?
Brad Marshall might be interested in these results. Given the high amounts of MUFAs, his 'torpor' theory suggests your metabolism would have slowed (unless, despite what looks like a high MUFA intake, you really had a predominately saturated fat intake). Your result suggests an 'emergence' response, where metabolism speeds up and fat gain is depressed in favor of energy production for spring and summer high activity.
I tried to look at the maccros, that ketobrick has 50g SFA so he may not be that high MUFA. But also to Brads theory, the Stored mufa is a problem, in LMHR they are so thin, there isn't much stored anything.
How much extra water did you drink? Fat is a water storage too so if you ate all that without drinking more water I am curious as to what your body is doing with all of it.
I'm curious, if you monitored sleep scores during this experiment; and if you did, did the calorie increase and increased RHR negatively affect your sleep. I find that high calorie days increase my RHR at the end of the day. That increase seems to crash my sleep scores.
Don't actually own a sleep tracker... feel like it would screw with my sleep. I'm the type to get in my own head about it. That said, my sleep hours did decrease... just felt "buzzed"
Spitballing here. Could the type of fat matter? In one success example you mentioned, a woman's fat source was predominantly cream. I've run across a few things lately about C15 being high in dairy products. Could that have anything to do with the results?
@@nicknorwitzPhD That particular saturated fatty acid, yes. I don't know enough about the science, but I do work with data and I watch too much RUclips. 😊 So take my "I wonder if" with that in mind. I noticed that that was a difference (other than sex) between you and your example success case. The particular saturated fatty acid that's been coming up in my feed about metabolic syndrome is C15. From Wikipedia: "Pentadecylic acid, also known as pentadecanoic acid or C15:0, is an odd-chain saturated fatty acid. Its molecular formula is CH₃(CH₂)₁₃CO₂H. It is a colorless solid. A laboratory preparation involves permanganate oxidation of 1-hexadecene." It's in dairy, but I do not believe it's in macadamia nut butter. It's also available in a pricy over the counter pill form and some of the hype could be coming from that manufacturer.
I tried this also before a blood test and disappointed, my Gp having heart attack with my ldl and trigs going up, total 14.5. only adding carbs drops mine to 8 with trigs still,
I've been eating an excess of 900 calories fat per day for the last year, my weight remains stubbornly at 65KG, I may be eating less other stuff but I'm not consciously restricting what I eat.
Hi Nick You are one of the very few people trying to push the conversation of diet and health forward and you do a great service to all of us. On a different note then this video, max heart rates and training zones are measured from some arbitrary numbers (like 220-age) Like yourself I have a low resting heart rate (66 years and 46 RHR) I’ve wondered why resting heart rate wouldn’t be used as a base because you are actually raising it from that rested number instead of an arbitrary number which doesn’t take into account someone age 66 who would be supposed to have the same max rate as me may have a resting heart rate of 65 instead of like my 46. That’s almost a 20 beat difference yet we would have the same max and zones. Thanks hope you find this thought interesting.
"You are one of the very few people trying to push the conversation of diet and health forward and you do a great service to all of us." - Thanks v trials. Re RHR... my age didn't really change during this week... I'd consider high 40s my baseline and it increases to 60s, as shown in graph
Thanks for the reply but i was more interested in your thoughts on RHR and zones (in general) in relation to some people having lower or higher RHR but the standard max heart rate numbers don’t seem to take that into account If you do the standard 220-age First person E.g age. 65 RHR 45 Max HR 155 Other person: E.g age 65 RHR 65 Max HR 155 You see first person has 15 more heart beats per minute before reaching 155from his resting number. That seems to me like that would be an important piece of information to put in a formula or factor for their Max HR I was interested in your thoughts or if it would provoke you to look further as I’ve not seen any one else consider this. Thanks
Highly interesting video as usual. Question: You mentioned that your insulin levels went up due to the high calorie intake in this experiment, and that's an explanation for the increased LDL levels. But in your OREO-test, your insulin levels would most likely have increasedeven more, but with a drop of LDL. Isn't that contradicting?
"You mentioned that your insulin levels went up due to the high calorie intake in this experiment, and that's an explanation for the increased LDL levels." -- where did I say this was causal? As mentioned, there are "push-pull" factors and fat cell growth/insulin appeared to "lose" the day.
I think that I will use that information to double my already "high" LDL of 235 to really bowl over my V.A. doctor who says that "I need to be on high dose statins immediately!"
short term increase in number of fat cells vs fat cell expansion needs more clarification. You're already lean, so your few existing fat cells reached a point of saturation rapidly , so you triggered creation of new fat cells for more efficient storage. More fat cells could increase the body's metabolic rate , and this hyperplasia likely signaled the liver to synthesize more cholesterol.
The body is amazingly intricate and individual. Thankfully I think I've found what works for me; I'm now metabolically healthy, *not* a LMHR but with a high LDL; zero result on CAC w/contrast, no statin although suggested by cardiologist. I've now reached my ideal weight and it will be interesting to see if my LDL has dropped due to the weight loss. There is short clip by Dr Steve Phinney talking about this (and he says they took biopsies) titled: Reason for LDL Increase for Some on a Low Carb Diet.
Interesting. Thanks for sharing. It would have been interesting to see subcutaneous vs visceral fat ratio diff before and after . To do justice to that, you would have had to get a DEXXA scan. Personally, my priority is on keeping my visceral fat at optimal levels. Subcutaneous fat may look ugly as you prolly already know, it is not as cardiometabolically lethal. Anecdotally speaking only with all other things being equal , I know that when I dramatically overconsume calories even for a week with all other things be equal(no sleep deprivation, no change in cardio or resistance training, etc.,) or more, the first place any minimal bf% goes is viscreally as per pre and post Dexxa scan. In the interests of fairness and respectfully, I have not had any pre and post bloodwork done doing that to see how it messes with my LDL. That would be interesting to do in the future to directly track how any visceral bf% increase no matter how minimal effects that I presume there would likely be a significant jump in LDL and if nothing else Triglycerides. Interestingly and on a somewhat related issue, I found absolutely no increase or decrease in my RHR Thanks again, I love that you think outside the box,,and are not afraid of backlash. Keep up the great work. I love all your content
8:52 Why would body increase metabolic/ energy expenditure rate to attenuate weight increase. This is not logical. If there is such mechanism in human physiology, obesity would not be a problem.
Is the fat absorption in the gut not limited by bile production, so while you may have been eating huge quantities of fat, it is possible you were not absorbing it all. You would need to measure fat in your poop to factor this in? Just a thought.
Nick, question- your precedent study from shoban was based on consuming heavy cream. Yes, there is fat, but there are sugars in the cream as well. So does your Oreo experiment more closely align to what she did to lower her cholesterol, than purely ingesting fat?
Crazy with a purpose. You should put that on you Dr lab coat
HA! Giving me thoughts...

Agreed!! 👌🏼
not too different from Marie Currie or any other scientist
I'm Irish-stubborn, keep my own counsel, don't tell me what I can't do...if only doggedness were monetized 😂 "They call you crazy till you prove them wrong, then they just call you lucky."
Nick, all these experiments that you are documenting and putting out to others is extremely beneficial to everyone. Instead of starving obese people for 14 or 30 days and making ridiculous conclusions, the idea of studying people who Don’t gain weight no matter what they do is going to open up the world of knowledge. It is quite amazing all the things you are willing to do and eat. Thank you.
You’re not the first to say that… but thank you 🙏🏻
So what drives NEAT in “hard gainers “ like yourself? Are there other factors involved with hard gainers?
I find it heartbreaking to see people, mostly women, that are overweight, struggle with all the signs of insulin resistance and they are trying desperately to lose weight - and they say "I eat close to nothing. Oatmeal with skim milk, and banana and an apple + a small glas of orange juice" and of course here everybody knows what a desaster of a breakfast that is - but good luck trying to get them to think of two eggs, bacon in butter and a coffee with heavy cream as the weightloss alternative.. They think you are making a bad joke, bc the TikTok Influencer that said "watch out to not pour to much olive oil on your salad as this is a hidden calorie bomb" never mentioned THIS!
thanks for this!!! I love your open mind and your integrity. I also did the Feldman protocol, just to see what would happen- before my LDL was 310, afterwards my LDL jumped to 524! It shocked me. My triglycerides doubled (still under 100- my tris are usually around 43), and my HDL went from 81 to 89. 1 lb weight gain. Also my heart rate jumped from 57 to 73 and my blood pressure went from 90/54 to 116/72. Overfeeding is REALLY not my friend. I started adding in 40 grams of carbs a day, divided between two meals and my LDL dropped to 180, my tri's back down to 45 and my HDL went back to 81. Interesting sh*t.
Interesting. Are you "chronically lean" too?
What's interesting the more veganism is forced upon us the more they move these markers to suit themselves.
I m about to add carbs to my diet to "normalize" my lipids numbers. Question: did u bring the fat down o did u maintain it at the same level? thx
All this indicates is that variability between people and the fact that these LDL metrics change so quickly depending on what you eat, there is no way this metric can be used to assess anything. It's just a convenient measurement because it can be done so easily, but to base a whole treatment plan on something so variable makes no sense at all. I don't understand how the statin and decreasing cholesterol theory is still pertinent.
"LDL metrics change so quickly depending on what you eat" -- this is revolutionary to some... DYNAMIC
I've used this protocol to reduce my LDL to pass a military medical twice now, it works in just two days of 5,000 calories a day of fats, a third and fourth day reduces it a bit more each day but for me, most of the LDL reduction happened in the first 48 hours. I did have a blood test after two days, then the third and forth day to see the change.
Warning! Eating that many calories of pure cream and cheese is not pleasant, OMG, stuffed. Try drinking 1000 ml of heavy cream in one shot, not so fun. Again, my LDL went DOWN, not up, but most important for what I needed was the LDL to HDL ratios went back to the normal range which is what I needed to pass the test, otherwise I was going to have to due a nuclear stress test with heart echocardiogram which I wanted to avoid due to my age, fearing I'd fail it due to being too out of shape. What I did was a CHEAT, but most doctors are clueless this can be done.
Shawn baker did something like this as well…cholesterol is a dynamic measurement, putting people on drugs for a dynamic measurement is complete insanity
@@nicknorwitzPhD talking about dynamic measurements so is your fast glucose this is just a waste of time also.
I’m currently using a cgm and it changes depending on exercise, time of the day or carb eating which have only eaten to check things out. My glucose doesn’t change when I eat my normal meal of meat. Which means my glucose level is always a fasting reading except when carbs are introduced. Btw without carbs tit varies from 120-60
It's pertinent because it's profitable that's it.
I love your nuanced approach. Your honest understanding of what missing data means to the health community, and your recommendations as few and far between as those recommendations are.

I love, absolutely love your approach to explain and modify your existing hypothesis to accommodate this last experiment instead of writing it off as an outlier like has been done by controversial figures in nutrition research.
It really seems like you, Feldman, and colleagues are developing are great working theory of human metabolism that's been missing
I tried the Feldman protocol and my LDL went up and my TG went down. I am not lean mass, I am obese. The Feldman protocol obviously does not work for everybody. I could not speculate as to the reasons why. I did not want to tell my GP what I had done and had to argue about refusing statins.
Like you, I'm obese, so I'm saying this as someone with similar experience, not in a negative way. We are obese because we are metabolically unhealthy with chronically high insulin and damaged mitochondria. It's impossible to lose weight until our insulin is low. Our fat cells are already jam packed full. The Feldman protocol is clearly for someone who is metabolically healthy.
Oh, and just wanted to give a tool for talking to your doctor about what is more important, statins or something else (like diet). Here's a link to a video by Dr Ken Berry, "How to NOT DIE from a Heart Attack"
ruclips.net/video/BIg8A_i4hhI/видео.html
It's not about LDL cholesterol lowers statins hit the market in 1984 and Heart Disease continues to rise ,, ask for Lipid Partical testing
You shouldn’t be worrying about cholesterol, you should be worrying about obesity. Maybe try Ozempic?
@@Starfish2145 Ozempic?? Uh, no! It will paralyze your stomach and cause long term problems. Just go ultra low carb or carnivore.
You are missing the effect of the FADH2:NADH ratio - you might want to read up on the proton series at hyperlipid. Fat is not one thing - but a family of things - each with different effects. We did not evolve to eat high dosages of plant oils. Anyway - the LDL theory of CVD is pretty much dis proven - a better way to look at CVD is as a thrombotic disease - A good place to start is with Kendricks' books. Insulin levels are way more predictive - chronically high insulin as is found in people suffering from T2D. Insulin is not just about blood glucose levels - it shuts down autophagy - reducing the ability to re-absorb blood clots that lead to narrowed arteries.
Hi Nick, this comment is unrelated to the current video but I was wondering if you’d be willing to make a compilation video of sorts on the keto foods/meals you eat in a week. I can’t speak for anyone else but I personally would find that very helpful/interesting. Thank you for taking the time to read this comment.
See my recent Newsletter, section on Transparency, and you'll gather why I tend not to do "what I eat" videos...
I'd love to see data comparing outcomes between people who've gone hypercaloric using only animal fats vs using plant fats or mixed sources.
I am on a fat fast as we speak.
Thanks for the video! My personal experiment didn’t go so well: it appeared that carnivore plus TRT gives you a heart attack. I’ve been preaching low-carb diets for about 18 years. Last five years I’m on carnivore. And also was abusing PED’s for about 10 years. Now I have my coronary arteries plaqued. I am about to do a surgery. Unfortunately we do not have much data on that the price is too high guys
I don’t know when but some time ago I saw a medical show on TV I think. Anyway what they said was that it was sugar that would scar the interior of the blood vessels and the cholesterol would act as a bandaid filling in the scared part of the blood vessel. Like a scab only it didn’t know when to stop collecting fat cells and therefore clogging the veins. Which in theory might be why you can be low carb high fat and have a health heat?
What say you Nick Norwitz?
I have no idea what to think or believe anymore. I’ve eaten meat my entire life and avoided vegetables because they taste like shit. Last few years I’ve been avoiding carbs. I fast a lot because I’m never hungry and not by a conscious decision to starve myself. I seem healthy enough but I really have no idea!
Get a calcium scoring scan from your doctor. If you get a zero score, you're golden, and carry on what you're doing.
@@Ge1Ri4 And if it’s not? Eat a bunch of toxic veggies and become mental again? No thanks.
@@Ge1Ri4,
Except that the scan for CAC only shows hard (calcified) plaques. Soft plaques not detected by it are less stable and more prone to break loose and cause a clot/blockage. See Dr. Ford Brewer's videos comparing different methods (CIMT, stress test, NIVL Duplex Scan, CAC score) of assessing risks for cardiovascular disease.
Stop eating omega 6
That is crazy. You are probably nutritionally deficient. Why do you hate vegetables? Were your parents terrible cooks?
At 67, my health and longevity *IS* a crap shoot.
They lied to us about the 'dangers' of saturated fat;
The disregard for carbohydrates' effect on insulin levels affected my ability to lose weight;
The poisoning of my metabolism with industrially processed seed oils which have no place in the human diet;
And the messaging by the federal government nutritional guidelines to avoid meat (in itself a religious belief, which makes it un-constitutional IMHO);
means that I had to get guidance from RUclips.
I believe that this community saved my life.

so much passion I love your vids helps me stay keto, while almost everybody around me says Im crazy and have dead wish, and one more beautiful thing about keto after a heavy workout next day my muscles are not sore as they used to be when I was thinking that carb are the MAIN fuel for energy, I said sore, what I meant was actually next day I feel stronger and it lasts longer
I'm already lost the plot but here are some possibly related ideas:
- Eating that much fat might not get absorbed (bile secretion works as a safety valve), and the increased protein would lead to effectively higher protein ratio which might turn into glucose.
- I heard someone mention that cholesterols and plant sterols would affect LDL differently so if you changed your fat sources, things could change. Also, in case of unabsorbed fat, some types of fat could absorb with different priority.
Your disclaimer was absolute gold! Thank you!
Welcome :)
Some variables that might not be accounted for in this experiment. Eating a certain number of calories assumes those calories are all going into the body, there are variables that can change this even in the same person. Going to guess that your GI wasn't too happy and let you know. Also, that change in fiber would impact the microbiome in your gut which would be another variable that would make a difference, guessing trying to get the calories but limiting that fiber increase would change things, especially considering your GI history. You could also have a microbiome vastly different from your "average" person given past history, I think you mentioned having Inflammatory Bowel Disease, CD I think, damage to the gut from that would change how or what gets absorbed along with the potential of having gut bacteria that interacts with food much differently from others. I don't know the types of fats that you ate, but different types of fat absorb more or less depending on their type, the fiber can also change how much gets absorbed. Without being used to eat that many calories or those type of calories I'm not sure what impact that would have, the microbiome and the cells of the gut can change depending on what you eat and likely would take longer to absorb more of what you eat. Finally, there does seem to be impact of what food goes in based upon gut/brain interactions, as you likely have pointed out, we are not a test tube and the biology of our body is much more complex than most realize. Also recommend listening to the recent Huberman podcast where he talks with someone about the Gut/Brain interactions, that added some context to gut things that I hadn't thought about and would likely help you with future experiments involving food.
You could summarize your wall of text with:
Calories are a horrible way of measuring someones food intake.
@@snaxximan5737 Uh, no, it's not just calories, helps to read before you comment. LOL
This is a great response to consider. We are learning more and more about the micro biome and how much it really affects how we respond to food. So it really isn’t so much the calories. It’s what type of food, the makeup of the food, nutrient density and how gut bacteria interact with it.
We all know someone who can eat anything and not gain a single lb. Yet some people swear they gain a pound just walking past the bakery.
Don’t always agree with you but admire your willingness to test theories on yourself and you really present things well.
Dr Ford Brewer is using CIMT to detect soft plaque which is cheaper
Superb, interesting science combined with an excellent presentation. Good on Sir!
Glad you liked it!
@9:57 lipid energy model, good summary again to get the high HDL low triglycerides & high LDL thnx
I went from 80 gm carbs daily to 20. My LDL went from 55 to 110 to 182.
I’ve seen you. You’re pretty lean. Not surprised.
10:30... how did I miss this cool explanation of where HDL fits into the energy model before?
Sounds like you're learning... and loving it?
Bro, a rebranding and top pay video editor and it's 10/10 content with the deserved following and according pay that comes with it
So the added carbs for -18% and -22% LDL in high cholesterol diets are temporary effects such as while fat cells expand?
Yes, we are all similar but not exact. Yes differences in fat cell hyperplasia vs hypertrophy. Be interesting to see the starting triglycerides and ending triglycerides. Fun experience. An open mind is great. Too many find something they feel that works and then stop.
TG remain low... 40-60.
Hormones are a factor regarding lipid energy processing, especially estrogen level that fluctuates in women and also declines significantly with age.
When I removed added saturated fat and cut back on red meat. I used olive oil only after that on whatever I ate and ate mostly seafood, my LDL-C dropped from 360 to 145. On Keto/carnivore diet.
If you ever decide to repeat this experiment, it would be very interesting to know how your insulin levels were affected by the additional food. I’m not sure if someone can significantly expand fat cells without an insulin signal to do so?
I’ve had the same suspicions about my response to overeating. I used to eat tons of cheese (and I ignored my mom’s pleas to “at least have some crackers with it”). Sometimes cheese would be my entire dinner. It didn’t result in any fat gain-just things like nervous energy, inability to wind down at night, increased thermogenesis, desire to go for very long walks, etc.
Great point. I guess his weight gain was linked to the protein overeating and thus the extra insulin secretion. Actually, it seems like Nicholas performed the kind of study Dr Benjamin Bikman is calling for to dismantle the calorie hypothesis.
I am like you nick, same frame and build. Always ate close to keto for the last 10 years unintentionally. Now about to move to full keto... Cheers for the breakdown. Your a very clever boy.
You’re very welcome ☺️
@@nicknorwitzPhD have you posted anywhere the breakdown of what you eat daily? Not trying to copy. Have my own stuff l will always eat. Specially makeral and sardines. Always looking for ideas
You should do a video with Miche, Ph.D. She's on the vegan side, but very similar to you regarding testing things and research. You'd hit it off, intellectually, and we audience folks would enjoy (and learn a lot) from your discussions/tests. As a thin vegan who still struggles to keep my blood sugar down, I'm obsessed with insulin. I really do think it's excessive insulin release due to skyrocketing blood sugar that causes fat gain. I mean there's a reason why the average type 2 diabetic put on insulin gains 20 lbs. without eating more food the first year. I've noticed that when I eat low glycemic, I can ingest more calories and not gain weight.
When eating a healthy diet, you are doing little to no damage, requiring you to use cholesterol. Thereby using the cholesterol eaten in the food, was added in to your serum cholesterol.
This fits with my theory. When you eat a species specific diet, for humans that would be zero carb, high fat, moderate protein. The number of calories are irrelevant. When I started carnivore, to cure my type 2 diabetes, was eating a diet of 0% carbs, 70% fat, 30% protein. Equaling on average, every day for a month, 5,000 calories. With zero exercise. I lost 60 pounds. Going from 250 to 190 in 30 days.
And you got this from? "When you eat a species specific diet, for humans that would be zero carb, high fat, moderate protein. " Yeah, out of your A.

Answering virtually every comment, I have to admire the commitment. And having the capacity to do this in the context of keeping research and med school responsibilities on track. When I was in med school after prepping and eating some real food, keeping myself washed, dressed and fit, the only time left in each day was for about 4 hrs of sleep. I reassured myself at the time it would only be for a short while. It turned out that was the baseline for the next 40 years.
Ya… I’m trying to avoid that possibility… I’ve seen what toll it takes 😳
@@nicknorwitzPhD Perhaps I was whining. Rather, I would see it as a near optimal path for me. Some more sleep would give me a few less grey hairs and slightly better metabolic health. But the memories are irreplaceable. I was never able to attend a game or graduation but despite that my 4 children are all in the health care space. Like me they thought I was doing important work and having fun.

Thank you for doing your amazing work and being so public and entertaining about it. Great term this LMHR! That used to be called YSSJEM (You So Skinny, Just Eat More) - Im fascinated by all this and for once this community is about skinny people :)
It's been a while since I looked at it, but I thought the Feldman Protocol was to add carbs to lower cholesterol before a test.
I am glad you added the disclaimer section, I think with the tendency toward polarization that we are living in, it is important to state and restate precisely where you stand and sometimes more importantly, where do you NOT stand.
I unfortunately have seen your name used to defend people advising those with actual FH to let their LDL rip as high as possible, stating that they were of the belief that you have FH yourself and are not concerned about it since LDL is good.
Do you think the increased metabolic rate would be visible in the thyroid hormones?
Thank you,Nick! I stand with you in your declaration statement! So interesting, why some people don’t gain weight!

I switched from Plant based high carb diet to omnivore low carb recently, and have started seeing LMHR signs in blood tests (I've been lean all my life, and last 3 years at at my 15 year lowest weight).
What does your diet look like specifically in terms of fiber and fatty acid ratio. What is your BMI?
@@nicknorwitzPhD My fiber intake is >20g a day (20-30 I'd say). Fat around 65-70% of calories. BMI = 18,4. It used to be 20,5 before my 3y plant based period 😅 Trying to do more strength exercise and eat what my body asks for without forcing (I'm tired of forcing to gain weight).
My plan is to stay low carb, although I do exceptions, and to alternate with some keto periods. I just targeted being in ketosis once and I entered ketosis (I measured), without big effort (staying below 50g carbs).
My evolution in 9 months since I changed from Plant based (high carbs low-medium fat) to omnivore (decreasing carbs and increasing fat intake over this period, but still moderate-low carbs when I did my test 3m ago): LDL from 79 to 210; Trigl from 124 to 76; HDL from 36 to 65. I'll get a blood test done soon, will see how it goes now that I've been low carb (with exceptions). Thank you!!
@@nicknorwitzPhD Thanks for your answer.
I'd say my fiber intake is >20g (20-30), and 65-70% fat. Why you ask especially for this ratio?
My BMI is 18,4 😅. It used to be 20,4 before WFPB diet with normal activity.
Now I eat: Vegetables or salad with every meal (2 or 3) (prioritizing low glycemic index), some nuts/seeds. Meat, fish, eggs, some goat/sheep cheese/yogurt. Raw Coconut & Olive Extra virgin oils, avocados.
I don't eat (only occasionally): sugars, flours, starches (only resistant ones), refined oils.
Evolution in 9 months since I progressivly changed from Whole Foods Plant Based (high carbs, low fat) to 3 months ago (omnivore low/mid carb) (when I got lab test). During that time I :
LDL from 79 to 211
HDL from 36 to 65
Trigl from 124 to 76
My plan is to continue low carb with Keto phases, to reassess shortly as I'll get some blood tests done soon.
Thank you! Best regards.
@@JssRider Interesting. Consistent w/ present data for sure.
Your intelligent, self experimenting fascinates me. I appreciate your willingness to share your personal medical information. Please be careful that you don’t permanently damage your health.
Hi Nick. I just watched a few of your videos and subscribed. I have a question. Do you think the size of your lipid cells could be a factor in your experiment? The reason I ask is because I was told that I have large “fluffy”lipid cells in my blood and not the smaller “sticky “ lipid cells that can clump together……causing plaque formation in the arteries. ( my cholesterol is very high but I have a low blood pressure)
Hey Nick. Interesting results! I recently got my labs done and my LDL continues to climb up to 20.51 (canadian measurement) which translates to 793.12 American measurements. My doctor is freaking out understandably. I'm 65 and 109 lbs and I am very active athletically. I have a zero cac score. Any thoughts? Oh and pretty much Carnivore.
What's your HDL and triglycerides?
My triglycerides are 118 and HDL is 81. I would like the triglycerides to be lower but not sure how to do that.
CAC isn't a reliable score, not matter what the Carnivore charlatans tell you. Once you have calcified plaque, you are very, very atherogenic. But, likely you won't listen to science. But, $30 or so, get an APOB test and see where you stand.
You mean ldl 793?
I am fascinated by your experiments and your results!
Let's go!
I’m a LMHR, went carnivore/low carb 2 years ago. Before that for 3 years my RHR averaged 55 BPM, since starting low carb it’s been averaging 61. I used to struggle with POTS type symptoms but I haven’t since eating 90% meat diet with zero to a few low carb days a week. I feel better and lost weight but wonder why low carb made my RHR go up. Just staying curious!
What would also be interesting is measuring macros' calories against workouts, and energy expenditure- not only for the calorie differential I.e calories consumed versus calories expended during work, but also the amount of work- energy and coenzymes that it takes to digest the macros in question. For example, bile salts are produced by the body to digest fats and it takes the amino acids taurine and/or glycine, used along with cholesterol to conjugate into bile salts. It would be interesting to measure the amount of cholesterol in the food against that used making the bile salts to digesti the amount of fat, whether it's dietary, cholesterol or cholesterol the body is producing. And the total energy expenditure in digestion which is often overlooked. Seems like it would be something measurable through known equations.
It helps to understand fat metabolism too which researchers are still working on explaining.
Question, were you taking any digestive enzymes with that, like lipase? Would you because of such high fat ingestion put a warning for people with liver, gallbladder and pancreas issues here for the high fat intake? Or would it be certain types of fat more likely to give you problems like cooking oil that has been cooked into foods?
Asking for people over the age of 50 who also may have some metabolic/digestive issues, like a tired liver, gallstones etc.
This is similar to the Hadza experiment. Feeding them with SAD. No effect in energy metabolism short term. Nick nows almost nothing about POMC but some about Leptin. That is the key to this.
Have you ever measured how much calories excreted out of your body daily? Some energy balance calculation could shed more lights on what your body utilizes under different contexts. Or is it even possible? Any way to correlate to combustion of intake and excretion mass to intake and outgoing calories?
I've done this as well before prior to certain labs just to test it out. Definitely worked for my cholesterol lowering. Doctor didn't care much, though.
I will say whenever I ate so much my temperature will _always_ go up by A LOT. Like I'll be waking up at night in a pool of sweat and so on. My heart rate can as well go from 45-50 resting to a whopping 100 resting heart rate depending on just how much I've eaten the previous day. I don't gain much weight either as my weight will usually drop to below previously measured within a week or two tops, no matter how much I tried to overfeed myself. It's quite interesting.
I've done a 10MCal a day for a week experiment before as well, though with processed foods. It didn't end well as I literally couldn't walk by the end, it was wild, but it taught me what ultra porcessed foods do to your body really well. Meanwhile overeating (though less kcal) on a keto-diet had none of thse bad symptoms.
Disclaimer, my not fully understanding the physiology, but I have 2 questions. First one is simple. Was the increase in NEAT due to the thermogenic effect of food? And second, could it be that you appear to be so very lean, that there wasn't enough fat mass to expand? Perhaps comparing to others who have done this (Sioban), Calories per body weight or per kg of fat mass. Might there be an inflection point of overfeeding beyond which LDL would increase rather than decrease? Again, indexed to, say, total body weight or fat mass? Rather than just an increase in energy expenditure.
can you do a video on guidelines and advice for people who want to fix metabolic syndrome and/or diabetes type 2? which is a lot of ppl today

You can use ad libidum saturated F by long fasting period. I experienced higher resting heart rate and body temperature with an 11 days water fast...
This raises a new question: why do your compensatory mechanisms engage, and can we cue into this to make it happen more for ourselves. For instance, after a large meal, force yourselve to walk, bike, whatever to expend energy (get more of an interoceptive feeling for when you have energy abundace and make sure to use it)?
"why do your compensatory mechanisms engage, and can we cue into this to make it happen more for ourselves" - very good question and not one with an easy answer...
After a nights cogitation on this, a couple of seemingly obvious hypotheses came to mind all based on making your body practice this: 0) Low carb and insulin diets to tell your body to burn, not store, energy (though stem activation with insulin and abundance of nutrients should be cycled too) 1) High Intensity Interval Training to mobilize huge amounts of energy flow to musculature and metabolism in general, 2) themogenesis by engaging cold and getting your body to energize to keep you warm, 3) fasting to make your body tap into energy stores not normally accessed. In fact, all of these can be used to boost metabolism and probably mitogenesis as well. Practice makes perfect. I've picked the main principle up from Lane's books: life is energy flow. (Luckily, as humans we have the ability to direct how the enery flow is used. ;^)
A great video. I gained insight into our interior workings.
Glad you found it interesting and valuable
I'm a lay person so forgive my ignorance. Am I correct in understanding that thr reason the Feldman protocol did not work for Nick was because he raised his energy expenditure ie he was doing more exercise while he was on it than he normally does?
My body “auto-compensated” by increasing my involuntary energy expenditure through increased body temperature, heart rate, and NEAT
How much did the unsaturated fat of cashew and olive oil affect the outcome?
Cashew? You mean macadamia? Probably very little. Sat vs Unsat doesn't appear to impact my LDL-C much w/ my highest LDL-C of all time being when intake was 1:5.67 sat:unsat ratio
Love this. How many days did it take to see an increase in body temperature & resting heart rate?
You can see in the graph... effect was basically overnight... metabolism pretty dynamic
Hey, this may sound strange but, have you noticed any changes in your stool consistency, smell, etc, during the 6000kcal diet? Also what is your normal energy intake (before/after the experiment)?
Was there any change in your triglycerides and HDL ?
Would be interesting to know, what the trend is (according to your n=1) of the expected response......As per lipid energy model, assuming your LDL went up because of your increased energy expenditure, and as you have been a lean mass hyperresponder, for enough time to reach homeostasis, a mild increase in HDL and mild decrease in triglycerides as well
I am in the same condition as you, Nicholas. I have a skinny body and high LDL cholesterol. What is the ideal solution for something like this?!
I understand we are all different, but would love to get more details into your diet and what you think is the best bang for buck calories. What I mean by bang for buck is not the energy calories in the food alone, but the total energy all things considered (i.e. thermic effect of food, etc.) and with all things considered can the difference be significant or negligible. Thank you.
Thanks, my main take away from this is the power of individual variability when making any comparisons even when the population cohort share many attributes such as LMHR. Every individual strives to achieve an optimal homeostasis based on his/her very individual circumstances at any particular time. I would go as far as to say that your individual measurements of bio-markers yield PERFECT RESULTS FOR YOU as an individual regardless of expectations based on averages taken from other population cohorts and especially from general population averages.
"power of individual variability" -- YES!
I wonder the increase in MCT oil is the reason your metabolism was ramped up verses using a higher carbon fat like beef tallow.
MCT from where?
@@nicknorwitzPhDMCT was the wrong word to use. Was it the increase in calories from monounsaturated fats is why your metabolism went up? Would your metabolism increased if you consumed saturated fat?
I would be interested to know what your apoB was before and after. I am a LMHR who has given up trying to gain weight. I can eat a million calories a day and I never gain weight. This explains a lot about individual results.My CAC is scheduled soon I am curious about the results of this test also. Thanks for your great work.
My ApoB tends to parallel by LDL-C, although my non-HDL/ApoB ratio is very high
Nick, did you showing your hdl trigliceride? Or I miss them? What is yr total cholesterol?
HDL ~120 TG ~50
Can you do a video on postprandial endotoxemia from a high fat meal? If high fat meals increase LPS in the blood, does that mean high fat meals increase inflammation?
Thank you for sharing your experiment. How you did you feel, in terms of sleep, alertness, energy levels and digestion?
Jittery. Less sleep. Very alert. High energy. Digestion "so-so" but certainly not as bad as the Oreo experiment
@nicknorwitzPhD That is exactly how one feels when eating a big meal too close to bedtime. Makes sense.
Brad Marshall might be interested in these results. Given the high amounts of MUFAs, his 'torpor' theory suggests your metabolism would have slowed (unless, despite what looks like a high MUFA intake, you really had a predominately saturated fat intake). Your result suggests an 'emergence' response, where metabolism speeds up and fat gain is depressed in favor of energy production for spring and summer high activity.
I tried to look at the maccros, that ketobrick has 50g SFA so he may not be that high MUFA. But also to Brads theory, the Stored mufa is a problem, in LMHR they are so thin, there isn't much stored anything.
How much extra water did you drink? Fat is a water storage too so if you ate all that without drinking more water I am curious as to what your body is doing with all of it.
I am not a camel 🐫
So in a normal person this has the opposite effect? Does it effect A1C as well?
I'm curious, if you monitored sleep scores during this experiment; and if you did, did the calorie increase and increased RHR negatively affect your sleep. I find that high calorie days increase my RHR at the end of the day. That increase seems to crash my sleep scores.
Don't actually own a sleep tracker... feel like it would screw with my sleep. I'm the type to get in my own head about it. That said, my sleep hours did decrease... just felt "buzzed"
Hey, this question may sound strange but, did you notice any changes in stool consistency, smell, etc. during this experiment?
Spitballing here. Could the type of fat matter? In one success example you mentioned, a woman's fat source was predominantly cream. I've run across a few things lately about C15 being high in dairy products. Could that have anything to do with the results?
So you’re suggesting that swapping unsaturated for saturated fats would lower LDL?
@@nicknorwitzPhD That particular saturated fatty acid, yes. I don't know enough about the science, but I do work with data and I watch too much RUclips. 😊 So take my "I wonder if" with that in mind.
I noticed that that was a difference (other than sex) between you and your example success case. The particular saturated fatty acid that's been coming up in my feed about metabolic syndrome is C15. From Wikipedia: "Pentadecylic acid, also known as pentadecanoic acid or C15:0, is an odd-chain saturated fatty acid. Its molecular formula is CH₃(CH₂)₁₃CO₂H. It is a colorless solid. A laboratory preparation involves permanganate oxidation of 1-hexadecene."
It's in dairy, but I do not believe it's in macadamia nut butter. It's also available in a pricy over the counter pill form and some of the hype could be coming from that manufacturer.
I tried this also before a blood test and disappointed, my Gp having heart attack with my ldl and trigs going up, total 14.5. only adding carbs drops mine to 8 with trigs still,
How was the bowel movements eating so much fat?
Is it possible that a portion of the fat ingested was not absorbed and excreted?
I've been eating an excess of 900 calories fat per day for the last year, my weight remains stubbornly at 65KG, I may be eating less other stuff but I'm not consciously restricting what I eat.
Hey don't feel bad about getting it wrong. I myself was wrong once back in 1970. It happens to the best of us.
I don't feel bad! I feel enthused! Being wrong is where learning starts!
😂😂😂
Hi Nick
You are one of the very few people trying to push the conversation of diet and health forward and you do a great service to all of us.
On a different note then this video, max heart rates and training zones are measured from some arbitrary numbers (like 220-age)
Like yourself I have a low resting heart rate (66 years and 46 RHR)
I’ve wondered why resting heart rate wouldn’t be used as a base because you are actually raising it from that rested number instead of an arbitrary number which doesn’t take into account someone age 66 who would be supposed to have the same max rate as me may have a resting heart rate of 65 instead of like my 46.
That’s almost a 20 beat difference yet we would have the same max and zones.
Thanks hope you find this thought interesting.
"You are one of the very few people trying to push the conversation of diet and health forward and you do a great service to all of us." - Thanks v trials. Re RHR... my age didn't really change during this week... I'd consider high 40s my baseline and it increases to 60s, as shown in graph
Thanks for the reply but i was more interested in your thoughts on RHR and zones (in general) in relation to some people having lower or higher RHR but the standard max heart rate numbers don’t seem to take that into account
If you do the standard 220-age
First person
E.g age. 65
RHR 45
Max HR 155
Other person:
E.g age 65
RHR 65
Max HR 155
You see first person has 15 more heart beats per minute before reaching 155from his resting number. That seems to me like that would be an important piece of information to put in a formula or factor for their Max HR
I was interested in your thoughts or if it would provoke you to look further as I’ve not seen any one else consider this.
Thanks
I would be interested to see what a huge calorie surplus in a ketogenic context would do on a hypertrophy training routine.
Is there a protocol to raise ldl? I’d like to spoof my results the other way so I can get insurance to give me pcsk9 inhibitors
What would your (hard gainer) approach be to gaining weight?
Highly interesting video as usual.
Question:
You mentioned that your insulin levels went up due to the high calorie intake in this experiment, and that's an explanation for the increased LDL levels.
But in your OREO-test, your insulin levels would most likely have increasedeven more, but with a drop of LDL.
Isn't that contradicting?
"You mentioned that your insulin levels went up due to the high calorie intake in this experiment, and that's an explanation for the increased LDL levels." -- where did I say this was causal? As mentioned, there are "push-pull" factors and fat cell growth/insulin appeared to "lose" the day.
I would bet that limiting isoleucine and valine, while increasing glycine would have had very different results.
I think that I will use that information to double my already "high" LDL of 235 to really bowl over my V.A. doctor who says that "I need to be on high dose statins immediately!"
short term increase in number of fat cells vs fat cell expansion needs more clarification. You're already lean, so your few existing fat cells reached a point of saturation rapidly , so you triggered creation of new fat cells for more efficient storage. More fat cells could increase the body's metabolic rate , and this hyperplasia likely signaled the liver to synthesize more cholesterol.
The body is amazingly intricate and individual. Thankfully I think I've found what works for me; I'm now metabolically healthy, *not* a LMHR but with a high LDL; zero result on CAC w/contrast, no statin although suggested by cardiologist. I've now reached my ideal weight and it will be interesting to see if my LDL has dropped due to the weight loss. There is short clip by Dr Steve Phinney talking about this (and he says they took biopsies) titled: Reason for LDL Increase for Some on a Low Carb Diet.
Interesting. Thanks for sharing. It would have been interesting to see subcutaneous vs visceral fat ratio diff before and after . To do justice to that, you would have had to get a DEXXA scan. Personally, my priority is on keeping my visceral fat at optimal levels. Subcutaneous fat may look ugly as you prolly already know, it is not as cardiometabolically lethal. Anecdotally speaking only with all other things being equal , I know that when I dramatically overconsume calories even for a week with all other things be equal(no sleep deprivation, no change in cardio or resistance training, etc.,) or more, the first place any minimal bf% goes is viscreally as per pre and post Dexxa scan. In the interests of fairness and respectfully, I have not had any pre and post bloodwork done doing that to see how it messes with my LDL. That would be interesting to do in the future to directly track how any visceral bf% increase no matter how minimal effects that I presume there would likely be a significant jump in LDL and if nothing else Triglycerides. Interestingly and on a somewhat related issue, I found absolutely no increase or decrease in my RHR Thanks again, I love that you think outside the box,,and are not afraid of backlash. Keep up the great work. I love all your content
Great channel…thanks for your time☺️
Thanks for your time! You’re the one who just spent 19 min on me 😅
8:52 Why would body increase metabolic/ energy expenditure rate to attenuate weight increase. This is not logical. If there is such mechanism in human physiology, obesity would not be a problem.
Are Star Wars Oreos logical? How about the CIM? ... www.nature.com/articles/s41430-022-01179-2
Is there any evidence that dramatic overeating causes some portion of the food to just pass through, as in not be metabolized into energy?
Is the fat absorption in the gut not limited by bile production, so while you may have been eating huge quantities of fat, it is possible you were not absorbing it all. You would need to measure fat in your poop to factor this in? Just a thought.
Nick, question- your precedent study from shoban was based on consuming heavy cream. Yes, there is fat, but there are sugars in the cream as well. So does your Oreo experiment more closely align to what she did to lower her cholesterol, than purely ingesting fat?
Heavy cream is
@@nicknorwitzPhD got it. Thanks, Doc
