Doctor here. The most obvious issue with this study is actually something you didn't mention. This is the first time I've seen anyone trying to point at healthy individuals and determine their optimal insulin levels. The term "insulin resistance" is typically meant to be a proxy for muscle and fat cells' reduction in transmembrane uptake of energy sources. In other words, it's just another way to say someone is at risk for elevated fasting glucose. This is important because glucose, not insulin, is what damages small blood vessels (obvi). Anyway... This study literally didn't study (or maybe didn't publish) fasting glucose readings. Pretty unusual since the diagnosis of insulin resistance confers some negative consequence on blood sugar regulation. I think they literally only chose the term "insulin resistance" because it grabs the attention of those interested in impaired blood glucose regulation. In the absence of elevated glucose and elevated BMI, what good is it to know the C-peptide level of someone who eats 250 grams of carbs per day? Love the videos. Glad you mention the other 5 things that were a bit absurd about this study.

It's great that your comment wasn't immediately removed. However, you should be aware that his focus is really on critiquing low carb diets in every possible way, often resorting to misleading information or even outright lies. As many of us are aware, there's a whole business built around the idea that it's fine to eat plenty of sugar, as long as it's done "in moderation."

Physiologic “insulin resistance” from a low carb state is a normal and natural adaptation. This is different from the “insulin resistance” people actually refer to when you have an obese/TOFI or metabolically unhealthy individual. The first is normal and healthy, the second is an indication of a damaged system

[@RandomHuTaoSimp]

Yup, and no science on earth can underpin physiological carb intolerance as being harmful the way ACTUAL diseased state insulin resistance is. yet vegans and plant based folks will run to this carb intolerance notion as being harmful in the same way as insulin resistance is when they have 0 data to back that idea, in which case I say insulin resistance is a term used to define an idea, that is subjective by nature. carb intolerance on low carb, high fat is a protective mechanism the body induces to create a homeostatic setpoint which is indeed adaptive. And since our species is predicated on adaption, it would be foolish to argue otherwise.

[@amandabousheley3189]

Alright. So... thank you for this! I eventually want to move into a more balanced diet, and this sheds a little light on why maybe i should try... I had a lot of digestion issues when I started my fitness journey because I was consuming a lot of raw ruffage trying to eat high volume, low density... research took me to the keto diet where I lived for about 3 years, but still suffering from R.A. and other autoimmune symptoms, I tried carnivore and fell in love. I found a lot of healing and reversal of symptoms and drank all the kool-aid.. well aware of placebo and psychosomatic side effects. I have brought some sweeteners, 100%chocolate, and plants back in, but stay relatively zero carb on a daily basis. I have to say that I truly enjoy my diet. I am not super hungry and I don't feel as restricted as you'd think. It's simple and easy to stick to most of the time. I have wondered about adding more carbs for performance, but there's this fear in me that I'll flare up my RA and that my body may not be able to process carbohydrates any more. It would be so so so super helpful if someone would make some content about EXACTLY what you'd recommend as a protocol to reintroduce foods you've taken out. Everyone says to add one food at a time and wait 3 days. Okay. Cool. How many carbs should that food have? Being that I'm tracking calories should I adjust my caloric intake to make allowances for the added water? Should I wait a certain amount of time before weighing in? Is it dangerous to have too much sugar if you haven't had it in years? Say, if you have accidentally made yourself insulin resistant? .... no one talks about this kind of diet after the diet and I just wish there was content out there about it. Especially from someone I trust!

[@motomatta1]

I have the same questions 😊

[@brucejensen3081]

Surely ultra processed carbohydrate would be worse. Resistant carbohydrate better. Lactose and gluten should be fermented. Like beans or Jerusalem artichoke and white sugar or white flour are going to have very different impacts, surely

[@jacquishugar6761]

The study doesn't actually show that low carb diets cause insulin resistance. Insulin resistance and pre-diabetes is pretty much the same thing. In the study both the "low carb" group and the "high carb group" fall between 5.2 (low carb group) and 5.5 (high carb group) for fasting blood glucose. For pre-diabetes according to the mayo clinic, the criteria for diagnosis is a fasting blood glucose of 5.7-6.4. Hardly candidates for insulin resistance in this study.

@@binathere2574 yes sorry, by moderate carbs I meant no white rice and white flour and white potatoes. Sugar of course or any sweeteners, honey or maple syrup.

[@RandomHuTaoSimp]

Saturated fat intake does not cause prediabetes, diabetes or any disease state pathology. No science can underpin this. Also I've been consuming LOADS of saturated fats for over 2 decades on animal based and I'm perfectly insulin sensitive.

[@Mrdsmith500]

Did they take into account any meds they might be taking? Higher dose statins will lower insulin sensitivity way more than people think. I know this first hand. What are the variables?

[@Henry-Jeffy]

I figured I would jump in and share my results. I ate a ketogenic diet for about a year along with fasting and I found that my A1C actually increased a little from 5.4 to 5.6 and my c-peptide went down. On a postitive note, I went from 180lb to 145lb while maintaining a good portion of muscle. Unfortunately, my fasting glucose went from < 100 to about 105 on some days. I've heard the term physiological insulin resistance and thought maybe that was coming into play and perhaps it was. I slowly introduced carbs back into my diet and noticed my fasting glucose dropped back down to the 90s. It's been a couple of years now and I should mention my weight has balanced out at 150lb so I've since looked at the ketogenic diet as a tool but for me it's not something I want to stay on forever. One thing that is confusing to me is whether or not this physiological insulin resistance is causing harm. If you look at it as black and white, sugars go up and therefore it's bad. However, I imagine that the sugars in my blood were derived from gluconeogenesis, not because I ingested food. I wonder if our bodies react differently in this case... At any rate, I noticed when I would fast throughout the morning my sugars would increase so that by lunch time it was around 112. After breaking fast, I would check again in about an hour and my sugars were below 100.

[@binathere2574]

Vegetables are carbs. Not just pasta etc... Apparently the wheat that is used for flour in U.S. is banned in Europe. So it could possibly be the type of wheat that is causing your issues. Having said that at one point in my life rice, bread and pasta made me gain weight. I can eat then now with no weight gain. So maybe they're is a deeper issue. Just a suggestion. I'm not in the U.S.

[@RandomHuTaoSimp]

Yeah this is normal, physiological process that is adaptive and protective mechanism by the body. high fat low carb creates carbohydrate intolerance because the body wants to use 1 fuel source, and its main source would be the high animal fat. So it lowers the pathways that allow for carb tolerance to become more efficient at burning fat. Unfortunately, many guru's and blokes, especially layne norton likes to call this "insulin resistance" as if its disease state, Which is completely false. If this was disease state you would be fat, sickly and brain fogged. Im pretty sure you're not

I had stopped using "any insulin" because I wasn't eating anything... nevertheless, it eventually became dangerous to continue using the insulin for the high readings, or the spikes in my BGLs... the significant weight loss from the food intolerance, made me much more sensitive to insulin!

I checked what my approximation would be for what that actually means and I assumed 2400 kcals daily, which resulted in low carb being anything below 270 grams of carbs a day. When I was following what I ate daily, my program was basically 140-160 grams of protein, ~80 grams of fats and the rest carbs. Often ended with more like 90-100 grams of fat. That means I'd have approximately 260 grams of carbs a day, which would be a low carb diet even though I considered it very normal diet and maybe even slightly more carbs than I'd naturally eat. Which makes me feel very odd that I'd be considered low carb dieting while stuffing myself with fruits and veggies and pasta and rice and oatmeal and full grain bread buns. Even when I aimed at 2700-3000 kcals a day with similar plan, I struggled to go above 300 grams of carbs a day. Without drinking juices and other sugar drinks. And I should be aiming higher in my carbs (but not too high! Be aware of that 390 grams limit of high carb diet!)?

[@mertonhirsch4734]

Low carb does increase the amount of insulin needed to manage a given number of carbs BECAUSE insulin manages fat too. It's well known that someone on a low carb diet (not hypocaloric) may fail a glucose tolerance test, but that's because they have moved over to processing fat for oxidation. It's a poor definition of insulin resistance, and is generally referred to as "physiological" insulin resistance. It keeps people from becoming hypoglycemic in times of the year when they ate very low carbs and high fat, like in the winter and it goes away in about a week. A couple of mountain men who only ate meat for 2 years failed glucose tests in like 1910 with 200+ glucose and within 2 weeks of eating carbs they passed.

[@JasonBuckman]

It isn't even physiological insulin resistance. Physiological insulin resistance isn't caused by diet. Physiological insulin resistance happens when the body has to be insulin resistant. It's when an adolescent is going the puberty or when a woman is pregnant. It's carb intolerance, not insulin resistance. The body is making less insulin, so it isn't ready for the carbs. It has to ramp up the insulin for the carbs as it doesn't have the insulin pre-made. Carb eaters have the insulin pre-made.

[@mertonhirsch4734]

@@JasonBuckman Not true. Been proven with type 1 diabetics that even when 100% insulin is injected, the amount of insulin needed to manage a given amount of carbs goes up by 200-300%.. Type 1 diabetics who go from 60% carbs to 25% carbs have almost ZERO reduction in daily insulin requirements and exposure. Reducing carbs and replacing them with fat doesn't reduce insulin requirements. The reason is because 1) muscle preferrentially load with free fatty acids instead of glycogen and ffas are released from adipose instead of glucose from the liver. The ffas can get into cells without insulin but insulin can't work on blood sugar as well when the muscles are FFA loaded. Genes for glycolytic enzymes in muscles are downregulated. There is only a small decrease in insulin response to glucose (people will have high insulin on a glucose tolerance test if they eat

Insulin requirement per unit of carbs goes up but not per daily energy needs taken in total, accounting for insulin required to manage carbs, fat, ketones, protein and liver output (basal). On a side note, if people have sensitivities to wheat, corn, oats, legumes, they may have a hormonal increase in insulin needs from those food sensitivities. Conversely, some people will have a rise in cortisol from low carb diets because carbs tend to raise serotonin and have a calming affect which can lower adrenalin and cortisol.

The actual question is what your glugoce tolerance is now if you ate some carbs. If you had a lot of saturated fat, it could well be that your glucose tolerance is lowered and if you consumed a diet with carbs you couldn't deal with it like normal anymore.

[@Marx1963]

@@cyberfunk3793 didn’t eat lots of saturated fat around 60 -80 grams per day . Yes I did notice an increase in blood glucose over the holidays when I eat more carbs than my norm . Had a HBA1c lab done and my level increased from 4.9 to 5.3. I was like wow a few weeks of eating carbs pushed my numbers up . I’m getting another lab test this week to see if it dropped back down . But yes I see your point.

[@cyberfunk3793]

@@Marx1963 I was meaning: your insulin sensitivity could lower long term even on a low-carb diet if it had lots of saturated fat that actually blocks how insulin functions. Avoiding carbs can be just masking the problem, like a person avoiding peanuts isn't actually curing that allergy even though their symptoms disappear when they don't eat peanuts. Probably the best thing to do for normal blood sugar is avoid all unhealthy foods and get to a healthy weight. Good thing if you don't get a lot of saturated fat though, I think many people on keto do. I never avoided carbs and my blood sugar was good last time it was measured.

@@cyberfunk3793 glucose tolerance and insulin sensitivity are separate things, e.g. type 1 diabetics can be very glucose intolerant, but still very insulin sensitive. Long term low carbers do get lower glucose tolerance, but their insulin sensitivity generally improves. It's just that their pancreas does not store insulin like it usually does as it is not needed for their diet; introducing carbs slowly over 2-3 days returns glucose tolerance to normal (or better) levels. edit: no idea where that saturated fat warning comes from though

[@cyberfunk3793]

@@defeqel6537 It's the same basic problem: you have low insulin sensitivity which leads to pancreas pumping more insulin until it cn't keep up anymore and you have diabetes. Low glucose tolerance just means you blood sugar spikes, because you can't produce or use insulin efficiently anymore.

Yeah, isnt this study just tracking carbs and nothing else? For all we know the 'low carb' people get all their carbs from beer. It was a small group. "Even though such an analysis provides a better approximation of the entire population, several limitations should be considered. For instance, the dietary intake in this study was assessed through self-reported diary logs and not by intervention. Even though adequate training was given to each participant along with a food scale, we could not possibly rule out false reporting." "It is also crucial to note that, although there is a significant correlation between low carbohydrate consumption and IRS risk indicators, this should not be interpreted as a direct impact but rather as a contributory behavioral factor that could enhance the probability of such an outcome if continued uninterrupted over time." In other words, a correlation on a small sample size, right? With probably made up numbers. For all we know the

Do you have visible abs? If not, you're probably not all that lean even if you weigh little. You need to be below 20% and probably below 15% to see actually defined abs. Can look up some pictures for an estimate.

A great review ... Another disturbing aspect is the groups were unequal making statistical analyses a challenge (ANOVA) -- I am NOT a statistical expert outside of RCTs (this is a cohort/observational study), so I will leave the detailed stat review to others better skilled to do so. A better (cleaner statistically?) approach might have been to divide the 120 subjects into 3 nearly equal groups depending on intakes, or even 4 groups to get more separation AND (potentially) better statistical comparisons. Lastly, there were some in each group who were more or less insulin sensitive than in the other groups. That is a great benefit of providing individual data points. Great work as usual Dr. Norton!

[@item6931]

I'm only an "expert" (gotta be careful with that term - some very smart statisticians out there) with ANOVA in the context of factorial design to generate regression models for engineering optimization, so I don't think I'll read this paper lol

@@item6931 Oh I know, I sat through 4-5 grad level stats classes with those who wanted be statisticians. I stay in my lane -- for example, non-parametric stats are often looked down upon, however, in some applications (sports science) they are THE best option for external validity and translation for other athletes. Most scientists stick with means tests, yet athletes and coaches do not really care about the average time for 100m.

A bit disturbing that the differences in lean mass and waist circ was significant enough to hint something is going on. I do not know any science backing it up, but observation tells me people who eat a lot of high carb (the crappy variety - high GI) tend to have more fat around their waist - even though many of them restrict calories to lower than they should. It could be that people eating lot of carbs have less appetite for protein. True low carb (less than 30 %) and KETO enthusiasts have mostly fat for energy - but almost everything that is high fat and edible has significant protein content (meat, dairy, nuts, eggs).

[@ruthhorowitz7625]

Can we stop lumping all carbs together. There's a huge difference between an apple and a teaspoon of sugar.

It's not like we can't all just test our fasting glucose on different diets to find out if this is true on an individual level. I'm lean and borderline prediabetic, and for me it definitely is not.

40/30/30 is basically a Zone Diet starting point (it can be adjusted based on hunger as a proxy for varying insulin response). Me thinks Dr. Barry Sears, PhD would take scientific offense to the generalized conclusion. The world-best athletes that use his diet would also suggest this is not true (Dara Torres, Jenny Thompson, Valentina Vezzali, Dean Karnazes, 2004 Italian national basketball teach, the team champion Tour de France team, etc...). I doubt insulin resistance is producing all-time, never-seen-before greats. Dara Torres missed gold in the 50m free by 1/100th of a second as a 41-year old mother... Yes, they ate more carbs, but ONLY because of their immense activity level. Compared to athletes doing what they were doing, they were quite low carb.

I am lean-around 18%bf, have a superior Vo2 max (seriously, that’s what’s it’s called!), I’m 47 and I have an A1c of 5.5 and my insulin and c peptide is off the charts low. Feels ridiculous talking about this on a KZbin channel but I’m trying to figure out how to lower my A1c and have my pancreas produce a little more insulin. So, I have a cgm and gaining some insights. I feel like I need to be relatively low carb (lots of veggies and some berries, small amounts of rice and quinoa and some dairy) but I get so confused. Anyone have experience turning something like this around. I sleep, exercise, walk, do t have high stress (other than the exercise!), don’t over exercise… I used to have a binge eating disorder so lots of sugar and refined carbs (all good now but dealing with the health effects).

This is something I agree with from experience. I was low carb for a long period of time & every time I had a bit of carbs I’d feel very tingly. I felt very sensitive to carbs but ever since bringing it back over a long period of time that feeling went away. I could imagine how it would potentially cause insulin resistance!
