CORRECTION: ‘Dilute + Concentrate’ @ 7:57 There’s significantly more information on this topic that needs to be discussed, and I already wrote out my notes for the detailed analysis of both sides (I hope to record that this week), so I’ll release that soon. Beyond that, I may make a follow up to this video, as well, because I left out several studies used as proof in both camps, including the mechanism for why the metabolism was increased (they disagree there, too). Additionally, both groups cite one study as proof they’re right, which is odd… I’ll get into that, too.

[@Mario-forall]

You need yet another correction 😅. First you said "distil", which is a way to concentrate a solute, then you said dissolve, and finally settled for dilute, both of which reduce concentration. All good, after all you "only" have a PhD (or soon will) 😉

I had to get off carbs and go vegan loosing 1-2 bls a day. now 180 vs 235

[@tonyprice2256]

I am 66. I used to be considered morbidly obese according to two medical doctors who evaluated me. I also had a fatty liver condition, and was at one point diagnosed as being pre-diabetic. Throughout most of my life, i always had very good blood pressure, but later in life experienced occasional bouts of hypertension. I was also plagued with edema - excess fluids causing swelling in the feet and lower legs. That edema also led to those areas to be easily bruised, and injuries were slow to heal. Open wounds were prone to infections of cellulitis that required hospitalization on two occasions. I also developed a condition of peripheral neuropathy in the feet, and suffered the symptoms of COPD from decades of smoking, among other things. Just over two years ago, i changed what i was eating and even more importantly, the way i was eating. I began an aggressive program of intermittent fasting - eating just one big meal every day. I stopped consuming all sugars, and drastically reduced my carb intake. I have continued this way of eating with a little 'cheating' here and there, since late June, 2021. A typical daily meal consists of the following: A.) a variety of steamed fresh veggies - two bowls on average. I use generous amounts of real butter, garlic and several other herbs and spices as well. B.) a serving of high quality locally produced free range meat protein. If it is fish it is fresh caught, not farmed. If it is from eggs, it is eggs produced by local free range chickens. C.) Also included in the daily meals are servings of cheese such as goats cheese or cheese made from the raw milk of once again, local free range grass fed cows. D.) I will also consume a few handfuls of nuts or seeds daily for additional proteins and healthy fats. After just two months of eating this way, i lost about 60 pounds of excess fluids and body fat, and with no increase in any physical activities or exercise. And beyond that the real magic began to happen. All of the chronic health conditions mentioned above that had plagued me for decades began reversing until they were all gone completely. Even the symptoms of COPD. No more chronic coughing, wheezing or shortness of breath. And i am still a modest smoker to this very day. Imagine that. The most stubborn condition that finally subsided was the peripheral neuropathy - nerve damage in the feet that was the cause of great discomfort. But yes, even nerve damage can be repaired in some cases. I use absolutely no pharmaceutical products - prescribed or over the counter for any reason whatsoever, and have no need to see any medical doctor. No medical doctor in my life has ever helped me reverse any of those conditions. I know what i have experienced is anecdotal, but i am not alone. Many people, perhaps millions of people have experienced similar results from a combination of intermittent fasting while eating keto and / or carnivore diets. I attribute my personal success mainly to the information and advice i received on KZbin from Holistic Dr. Sten Ekberg. My best wishes go out to all who have taken the time to read this, and those who did not. lol

I have similar experience, keto and intermittend fasting (3/4) over 6 months led to 14 kg weight loss. I had to stop this diet because my Psoriasis went bananas (I assume that the weight loss freed mercury or other toxins from the Fan cells). With a less severe fasting I am now well again and my blood values improved a lot, especially the triglycerides and cholesterol dropped which seems counter intuitiv eating a lot of fat.

[@Quixote1818]

I was born in the late 60s, and in the early to mid 70s, people rarely went out to eat. McDonald's was a big treat about once every couple of months. Healthy home cooked, non processed foods were the rule. Things began to change in the late 70s and early 80s. Restaurants and fast food restaurants begin popping up all over the place. We got better TVs and started seeing all kinds of advertisements for fast food. Both parents began working, and there was less time to cook healthy meals. So there was a HUGE cultural shift to poor diets, fast food, and temptation from advertisements to eat fast food. So people started getting metabolic syndrome and were constantly craving more foods. In my opinion, it was clearly a cultural shift of eating more and eating more processed foods.

[@Physionic]

Excellent point, Q. I tend to agree with you, wholeheartedly.

Logical analysis

[@mikeilabiddle1757]

There's also the fact that to go along with all of these convenience foods, the social stigma of eating outside of mealtimes has all but vanished completely in many places. When I was a kid in the 80's and 90's it was still kinda weird to snack a bunch outside of meal times, to eat in your car, to eat while walking around. At most I might get a granola bar after a particularly grueling swim lesson or the occasional gas station candy because I washed my Mom's windows. Now it's completely normal to be eating at literally any moment of the day and I think this definitely contributes another layer to this complex problem.

As a type 1 diabetic, I can see a direct correlation between my insulin usage and weight. Also, when I switched to a low carb diet, I felt pretty crappy for the first few weeks, although my blood sugar was much better controlled. But after that transition, I felt much better on a low carb diet and I am taking less than half the amount of insulin I used to take, my blood sugars are much better controlled and I have lost 30 pounds and have kept it off for over three years. Not to mention I am much more satiated and can go much of the day without feeling hungry.

[@Physionic]

All wonderful news, Peter. What you described are aspects addressed in both models, although they sound more in-tune with the Carbohydrate-Insulin Model.

[@mpoharper]

@@Physionic I would love to see glucose and insulin variability under both diets. I believe glucose and insulin variance is lower in low carb. I am an n of 1 with that. A CGM can track glucose in a trial however insulin testing needs some development. All I manage is fasting insulin which is interesting but not full story. Keeping these factors under control is important for diabetics and some cancer patients.

As a non diabetic I experienced a very similar history minus the need to inject insulin. I was prediabetic and heading to type 2. Now my health is much better. Always feel satiated.

This is my anecdotal experience. In 8 weeks of a low carb and very low sugar diet, coupled with intermittent fasting I have lost 20 pounds. I also exercise cardio/weight training with more emphases on the weight training. What has really astonished me is my blood pressure has dropped to a normal level. My BP hasn't been this low since my 20's. I'm 74 now. For the time being at least, I don't have to take 40mg of lisinopril. I am taking 10mg but just for kidney function.

Over 6 years I went from 250+ lbs to 140 lbs by being patient, persistent, determined & WILLPOWER! Not by low-carb, high carb, keto or any other fad diet

[@brettsmith5944]

Over 30 years I struggled following the conventional advice and trying to do this from a calorie perspective. So people close to me lose vast amounts of weight and short periods of time with a low carb approach. Dove into the research to show them how they might be hurting themselves And came to the conclusion that the one thing that changed in the environment while the world became obese and sick is the introduction of processed fats, the craze of going low to no fat and the consumption of processed foods that our great grandparents would not have recognized as food. Put 60 hours in late 2018 into researching this in November and December. Decided to go low-carb while continuing to study this because it became fascinating. Dropped 110 pounds in nine months. Since then while remaining very low carb I’ve been able to add 22 pounds of muscle without changing my waist circumference. Overarching big points learned and now studying this for over 5000 hours to years dedicated while we’re trying to write a book. Yes as mentioned in this video one of the keys is to understand time. It takes an average 4 to 6 weeks of very low carb intake to flip the metabolism back to our native metabolism that we are all born with. When in this fat adapted metabolism we can easily switch back-and-forth from processing carbs to processing fats as energy. This is why in short term you will find calories equal to or better than carbs. Once you flip the metabolism and you’re running off of stored body fat as your main energy source, And your fat intake with ancestral animal products is higher than most have experienced in the last 50 years, you become very naturally satiated. Most people who eat low-carb because they naturally get full quicker wind up resist draining calories without ever feeling hungry. I believe this is the number one reason for long-term success. We learned during the biggest loser competition trying to maintain a calorie deficit that most people use under the conventional method leads to a major reduction in their metabolism. Because they’re always on the blood sugar roller coaster cravings never go away where they do on the low carb method. So low carb solves many of the reasons that people fail on reduced calories. I believe there are many other physiological reasons why low carb is very advantageous but that’s too much for this one comment.

[@AI-vs7sm]

Could not have said it any better.! One glaring difference in all of these kind of studies, is that the conventional side KNOW that it takes time to convert, they know about "keto flu", the transition period involved, and they set parameters that they know will negate the advantages of low carb, and then say, " see we told you! " In particular, the amount of macros! 45% carbs or 40% protein is incorrect, and they know it. But, they can prove their point that way. A devious form of cherry picking!

[@grog3514]

Did you determine if low carb dieters are harming themselves?

I discovered that you can push your body into fat consuming from carb consuming by doing extreme cardio for 3 days on a normal diet. I discovered it while hiking in Montana. The first 3 days were awful and I felt sore, starved, and exhausted. But after the third day, it was easy and had no more cravings.

Funny thing is that just as not all fats are created equal, not all carbohydrates are created equal. There’s a big difference between the way our bodies process whole plants vs. sugar or even wheat flour. I think it’s pretty important to know what the high carbohydrate diets contain.

You’re way above the pay grade of any registered dietitian and most nutritionist, who are stuck in the mindset calories are a real representation of energy available in a food.

[@Physionic]

Great point, Michael. Typically, studies make sure the proportions of fats across comparison groups are the same. There may be some missed nuance there, but that'll take another analysis, which I hope to do in the future. The same applies to carbohydrates - the researchers normally control for differences in diet composition (simple sugars, as one example). And, in metabolic ward studies, every macronutrient is accounted for and is 100% equal across comparison conditions. Either way, it's a great point, and something to look into in the future.

However on the high carb diet I used to have cravings and I was hungry most of the day while on low carb diet, after 2 weeks I stopped feeling hungry all the time and could easily use intermittent fasting to help me regulate my calorie intake so it is by far the better method for me which also helped me to revert type 2 diabetes.

[@PinkieJoJo]

It is interesting to see everyone’s experiences. I’ve been high carb plant based and lost tons of weight. I’ve been keto and lots tons of weight. The issue is that with both ways I eventually became bored, felt restricted, and always hungry. I could eat a plate full of fatty meat and still be hungry an hour later just the same as if I ate a plate full of whole plant foods. I’m thinking perhaps for me the key is somewhere in the middle. Not everything in moderation but everything in balance. Idk. 🤷‍♀️.

[@BO2trickshoting]

perhaps this is due to the nutritional value of the calories. high animal fat contains more fat soluble vitamins, which could in turn make you feel more satisfied, whereas empty carbs probably will still leave you hungry

I live in a real world and at times I fail. Having said that I have developed a set of tools to recover from falling off the wagon and get back to my desired lifestyle choices. I stopped weighing myself long ago. I know what foods I can eat and what foods I need to avoid. The metrics that I use to determine my level of success are my blood pressure and how my clothes fit.

I just found this channel and subscribed. I really appreciate the lack of discernable agenda in your discussions, which is opposite to almost everyone in this space. I myself am pretty firmly in the low-carb, carb-insulin model camp based 100% on N=1 personal experience. I'm late 40s, spent my entire adult life overweight, borderline obese, pre-diabetic and flailing in my efforts to change that while listening to the "standard" advice of people like Kevin Hall. Tried keto starting about 8 months ago, lost 40 pounds and improved every health metric except LDL is up slightly, never felt better in general. In my experience, low-carb works for weight loss because the experience of hunger is completely different while you're in ketosis. Maybe this is consistent with both hypotheses (as I HAVE restricted calories). But the fact that I have less hunger and far better energy levels is undeniable. In any case, I'm still skeptical of everything, and I don't just want to view all of the evidence through the spin and gloss of advocates on the "side" I've found myself OR the other side. So I'm glad to find this channel!

[@BossNerd]

This makes total sense - I go on a low carb diet and it takes a week to 10 days for cravings to go away. I am evolutionary biologist - I take a different view from all these guys. I think I need to write a book. Human metabolism has evolved to adapt to a wide variety of diets - none of them are anywhere close to the modern diet. It is clear to me that high carb diets are a rare thing historically - we are designed to take advantage of carbs when available but you were never meant to eat the modern diet. Humans are versatile omnivores and our metabolism is not optimized like a Panda to eat one thing - we are de-optimized(for lack of a better word) to eat what is available. However, if we encounter a stable long term food source we can semi-optimize(again, for lack of a better term). Eventually, we will map out all the transcription factors and epigenetic mechanisms and this will all become clear. In the mean time you should pick a classic diet(good luck defining that) and stick to it - you can optimize your metabolism to it and be healthy. I have chosen the low carb, high fat/protein diet. Interestingly my hormone levels have returned to that of a 30 year old(I am almost 60) and my lp(a) is hovering around 3 - it used to be in the 30s.

[@brentbrouwer6135]

Yeah, it is important to take into consideration how our physiology developed. In the middle of winter look out your window and imagine what you would have been eating if you lived in that spot, say, 20000 years ago. I live in S Carolina. I would have been living on an oyster bed and steaming them in a reed basket much as the Ohlone did in the Bay Area. The only carbs probably from acorn flour cakes. Sugary carbs were rare and precious and designed for binging. Why? We were competing w every other creature wanting to eat those berries (probably eating that other creature into the bargain), and the safest place for those berries was "In muh belly!" where, gorging on those sugary treats sent them to my hips and thighs, the only safe food storage facility in that time.

[@DiogoVKersting]

I'm pretty convinced that a high carb, frequent meals approach will tend to fail even if it counts the calories. My impression is that indeed, eventually hunger is just gonna take over (or people will "compensate" by subconsciously moving less). And this is especially true for people that are already insulin resistant. But low-carb is not the only approach which controls for insulin. It seems possible to me that a high carb diet, combined with time-restricted-feeding, or fasting could work. Personally, what really worked for me was a union of low-carb, "whole foods" and time-restricted-feeding. I did not count calories, but I try to be aware of which foods are calorie dense, and try to portion-restrict those. When trying to cut calories without controlling insulin, my impression is that I felt lethargic and hungry. This in comparison to when I'm in ketosis, where I feel my energy levels are high despite calorie restriction.

[@maggimiller9634]

Let's talk about the ENORMOUS "average" American's sugar intake. It's in nearly every box or frozen item in the store, not to mention all the sweet treats available EVERYWHERE you look. This began increasing exponentially when the low fat craze started in the 70's - when all the big AG companies linked with the medical industrial complex & big pharma (because the tobacco industry profits were starting to become endangered and controversial) so they invested in sugar and started attacking ALL fats as the main culprit in diseases such as heart disease, cancer and our other terror inducing maladies. They started replacing wholesome, nourishing foods with addicting sweetness, simple carbs and unhealthy seed oils. They began putting it into literally everything we eat. Now we can rarely find foods without sugar, seed oil and at least 10 unpronounceable chemical additives. We now also have the added "convenience" of just throwing this garbage in the microwave. These big lies & the brainwashing propaganda (complete with mouth watering advertising ads) pounded into us constantly by big AG & their food production corporations, along with the millions of drugs the medical industrial complex and big pharma throw at us are only meant to keep us sick. An interesting fact is that there are only two countries in the world that allow pharmaceutical drugs to be advertised on television & radio - the U.S. and New Zealand. Basically we are nothing more than a $ sign for those intertwined corporations. They don't care about our health, they just care what our unhealthy brief existence on this planet can do for their bottom lines. "Let your food be your medicine" should be everyone's moto.

First of all, I’ll like to thank you, I’ve been following you recently and I like the topics that you present and how you do it!! Being a guy that once was 230 lbs. (I’m 5’9) I started by doing exercise ,I’m going into my 4th year doing CrossFit, that certainly helped, after that I tried the traditional method with a nutritionist, basing my diet plan on caloric density, caloric deficit and tried to do caloric surplus , I felt miserable, besides feeling weak, still had some GI issues, overweight etc, I simply knew that something was wrong, I started doing my own research, started with strict carnivore (this helped me with the most weight loss, my headaches and GI issues practically disappeared) but It was hard to sustain it after 3 months, then introduced fruit and raw honey (I felt better but started gaining weight and fat) then started focusing more on nutritional density, not caloric that much, my body entered in body recomposition, my weight didn’t fluctuate a lot but I gained muscular mass. I have been in this journey for a year now, basically in trial and error, and the last 3 months I have basically figured out my TDEE, I know what happens if I do an aggressive caloric deficit (500 per day) I tend to loose weight but eventually I’ll start to feel not so good, if I go over my TDEE but focusing on my macros (nutritional density and low carb approach, max 100grs of carbs per day), even though I’m over my TDEE I keep my same weight and feel really good, and most important (at least to my point of view) I’m doing my check ups and my triglycerides, fasting glucose, insulin, heart pressure and other metabolically healthy markers are within optimal range. I guess my point is that both approaches have their valid points and time is definitely a factor, and every body reacts differently, either approach is not a “one size fits all” suit, you have to grab the best practices of both and customize it to your benefit :) P. S I'm 176 lbs right now

[@niallstallard5936]

When I eat protein/fats, I get full, I’m satisfied, go on and do whatever. When I eat “processed carbs”, it seems the more I eat, the more I want. I can binge on carbs, have a full stomach and still be hangry. For me, it seems that I can feel “real food” vs. “fake food”, maybe I have a body/food connection. When I’m active, exercising I crave fats/proteins. When I was a sloth, I craved carbs. While 70 calories may not be much, that is an extra 350 calories a week. Over 50 weeks that is an extra 5 pounds per year. From age 20-40 the average American will lose 10 plus pounds skeletal mass which will slow metabolism even more. On average Americans could be annually both gaining 5 pounds fat while losing 1 pound of skeletal mass. Looking at a scale a person would only see a 4 pound weight gain, many of us would blow it off. However after 10 years, we find ourselves 40 pounds heavier and when we try to exercise, we have challenges because we lost 10 pounds of muscle. I know that my numbers are low balls, perhaps this could be the story for another video. Nicki

[@taylorhillard4868]

I think it really depends on the person, and maybe the source of the macronutrients. I actually lost a lot of weight and became underfat (technically I was normal weight bmi, but I had a lot of muscle. So I had too little bodyfat but wouldn't be classified as underweight) eating an almost completely fat free diet. Carbs satisfy me so much. I can get through the day on a bowl of rice and a regular soda. But if I eat something high in fat (even "healthy" fat dominant foods like nuts, peanut butter, et cetera) I will become ravenously hungry. Pretty much the only reason I stopped the low fat diet is because I wanted to gain even more muscle, and I was worried that with such a low fat diet I wasn't getting enough dietary fats to maintain enough cholesterol.

I think both these theories are missing the point. Things began to deteriorate when we stopped cooking using whole foods at home and started consuming highly/ultra processed food. This type of food is not only crafted to lead to over consumption (to maximised profits of the food industry) but also needs less digestion and delivers greater amounts of calories in a shorted period. We need to get back to cooking at home using raw ingredients and vastly reduce consuming food made in a factory, with ingredients we were never meant to ever consume.

[@willbrink]

Hall is right. Cals are #1 driver of weight gain, insulin is a key hormone, it alone does not create weight gain. Modifications of the standard model is warranted if/when new data exists, but some always go too far. Best nutri approach for weight loss is higher protein.

[@novideostoday]

@willbrink The best approach is to fast and eat nothing at all. High protein actually increases insulin making it more difficult to lose weight.

Team Ludwig all the way ... As an insulin resistant individual (HOMA-IR of 5.4) i can tell you that putting the first carb rich food in my stomach ( a fruit usually as i actually eat way healthier than what my waistline portrays) sends me into an endless cycle of hunger... It's literally like i have a black hole that can't be filled. On fasting days i have no hunger and my energy is better.. Have been on a carnivore mostly/ occasionally keto diet for the past 2 weeks ... I lost 5 kilos. And to prove the insulin theory more ... My weight loss turned into gain after i started consuming artificial sweeteners the past 3 days. I do actually have a question Don't know if this concept has been researched before... They always talk about calories in vs calories out. Are there any studies that discuss the difference in absorption between individuals? The thin members of my family have a pretty rapid transit.. going to the bathroom twice a day or 3 ... But those fatter have a much slower one going once in two days. The diets are pretty similar if not identical. Used to joke about us being the super absorbers that can survive a famine.

I am 61 now , and have been on a strict keto diet and daily 19hr+ intermittent fasting for 3 years, I started more than 5 years ago, after 2 of my brothers died, one from cancer and my younger brother from depression. It took my body nearly 3 weeks (I was only doing 16/8 IF for the first 1/2 year) to get fat adapted and started producing enough ketones to be comfortable with not eating sugar/carbs and being able to fast for 19hr+. Since about 2 years ago, I've been less strict on my fasting and have 2-3 meals a day with carbs every now and then, or when I travel, for up to 2-3 weeks. Now my body is so metabolically flexible, I can get to burn whatever I eat or not do any exercises and not gain any weight, and my body fat stays between 6-8% constantly. I feel much healthier, alert with no brain fog and I am able to do all the things or more than what I was able to do in my late teens. I am quite sure if I never started the keto diet and IF, I would have already died from cancer just like my parents and my brother, so i was very thankful for that. During the pandemic, one of my younger brother's friends died from stomach cancer at the age of 55 and another one just got diagnosed with cancer too. It might have been hard to stick to Keto and IF initially, but now, after ridden myself of sugar addiction and carbs, I have not been happier and healthier and I am very thankful for that. My 2 cents. 🧐

In a close system it’s true, but it’s far more complicated than thinking of the human metabolism is equivalent to a metabolic dumpster fire it’s not. It’s a complicated calorie burning calorie storing machine That we all try to understand but don’t completely understand it even after all the effort. My take away personally is do what you have to do to cause significant weight loss without compromising nutrition, such as the electrolytes, polyphenols, vitamins, and minerals, and then find something that’s sustainable for you. I use the ketogenic diet a little more carefully and with a little less urgency and some people because I went from 283 pounds in 2013 down to under 210 pounds as late as the fall of 2020, after which time I had an accident broken shoulder tore all my ligaments caught Covid And had a cytokines storm almost killed me. What sustainable for me is a higher protein diet which consists of somewhat leaner cuts of meat like steak, and then heavier like fatty hamburger and eggs from my neighbor, who lets her chickens run wild in the pasture she’s about a mile from me, and then some extra-virgin olive oil from places like Morocco, which I put on salads, I don’t cook with all the coconut oil that goes in the coffee instead of heavy cream, or anything else and avocado oil or coconut oil to fry with And then single ingredient foods, tomatoes, broccoli, cauliflower, asparagus, fresh cabbage, sardines, which I’ve had to learn to like because of their omega-3 three profile ocean fish like cod, wild caught of course not farm raised wild caught salmon once a year or so a tuna steak butter. I personally don’t eat anything up That wants white no matter what how much process I have been through I consider a pig to be a scavenger. That’s another reason why I don’t eat shellfish because they’re these they’re there they clean up brigade in the ocean, so try to stay away from too much tuna or swordfish because all other things being equal they’re at the top of the food chain and if there’s any way to concentrate mercury, I think they found a way to do it. I get pink salt that’s mined primarily because every piece of sea salt now is probably contaminated with nano plastics and I do use a little bit of conventional salt. It’s been iodized as long as it doesn’t have anything else in it Because I know I might not be getting enough iodine from my seafood, and I only occasionally dried kelp and I’d rather take it from Food than three drops of Lugol’s iodine solution when I think about it.

[@cawheeler27]

I've been doing keto for a few months now, for me it has worked amazingly well. I'm down 40lbs, and I never feel hungry. I think that's the main difference to when I would just do calorie restriction. Just cutting calories would always leave me feeling starving, thinking about food constantly, until I broke down and cheated. Then I'd feel like crap, and give up. That was the cycle for 15 years. Keto is the first time I feel as if I could do this forever. I'll sometimes forget to eat lunch, because I'm just not hungry at all. That is not a thing that would have happened to me in the past. I think most people on the Keto side would agree that a calorie deficit is ultimately the only way to lose weight, they'd just argue that the standard model of exclusively looking at the calories hasn't worked for decades and people are getting fatter and fatter. We need to acknowledge that satiety and food quality are essential to reducing calories. Keto, at least for me, has been the best way to get me off of processed foods and has gotten me eating foods that are good, natural, and give me a feeling a fullness. I don't even think about the calories I consume, I just eat until I'm full. It just so happens that I'm full while still in a deficit.

I think the predominate cause is the increase in widely available, cheap calorie dense food and snacks; the increase in demands for our attention by non-physical activities; and the resulting de-emphasis of cooking. In short, we spend our limited free time doing seated activities instead of physical activities and cooking, and eat less time consuming food which is higher in calories.

I have been low carb for almost two years. I lost 20 kg in the first 7 months. As a result I have often found that I just dont feel hungry and feel quite good on one meal a day, around midday and sometimes a snack in the early evening. With the size of the weight loss, I have been much more capable of regular exercise. My blood tests have shown a dramatic improvement in A1c, liver markers and trig/HDL ratio. I have maintained a protocol including sauna, cold exposure, nose breathing, no alcohol and increased sun exposure. There are so many interactions ..for example, not eating grains or seed oils seems to have helped me staying in the sun longer with no sunburn. More sun feeds into both vitamin D and NO. The hot and cold exposure with the extra sun and extra exercise helps me sleep much better. Being able to fast without discomfort and getting more infra red from the sun, as well as not eating carbs, all assists with mitochondrial health. The sauna is also assisting in sweating which assists in detoxing which in turn contributes to a range of processes, including improved methylation. The short point is that weight loss and overall health are the result of a highly complex multi-factorial system.

[@arallskiant9923]

Thanks for the vid. few things I feel would be nice to note: - the "sustainable"/adherence point (that i often hear like an excuse to muddy the water, like an ad temperantiam fallacy) can be quite misleading as its contradictory with the premise that one first has to change his bad habits (so you still need to state what count as bad/harmful and what is healthy, then stick to whatever you claim), hence it beg the question. - It is paternizing to say (in food guidelines etc) that people can eat a bit of butter or meat etc (or smoke) "moderately" as part of a healthy diet/habits even if it would be true (not saying it is) instead of telling what is healthy (whole plant food) and then let them decide. - Second people can lose fat with a drug addiction what matter more than body fat is health (eventhough they are indeed related). - It would be nice to add that one still need to avoid SFA in a high fat diet. the time needed to study is also the year after the person ends his (uselessly risky) keto diet. - In real/whole food proteins stimulate insulin more than carbs. Moreover carbs can help with insulin sensitivity unlike (animal) proteins (ectopic fat and compete with tryptophane absorbtion etc) and lipids (especially SFA). btw I found funny to get an ads from jason fung for a brand that measure ketogenic state in your breath here for me (not the first time here). Mediterranean diet is a plant based diet but initially not named plant based to please westerners/americans. though it bring confusion for some people who wrongly attributes its virtue to cheese/wine/oil/fish when the diet would obviously be better without it (real olives/grapes, no cheese/fish).

It took me about 90-180 days before I actually was able to lose weight on ad libidum keto. Like many others, going from 275 to about 230 was pretty easy once it started, but after that I had to use both serious time limits (usually OMAD) and being absolutely meticulous with Cronometer.

[@Michael-vc2cs]

This is a well done video. I happen to believe both have good points. The only factor I wonder about is the metabolic flexibility of the study participants. As someone who has done both the high carb approach and the clean keto approach(to be distinguished from the generic low carb model) it seems to matter greatly whether or not your cells can use fatty acids effectively. There was a point in my life where the higher carb approach stopped working as well. I was never tested but it seems like my ability to burn fat for fuel mattered greatly when I was in a high carb cycling approach. Keto is the diet that fixes this inability to burn fat for fuel when your glucose gets low. However, once you're metabolically flexible you can return to eating more carbs and experience good results because instead of your body telling you "I'm hungry" it simply switches to fat through the ketone signals. So following maintenance calories becomes easier after all of this. The science of this whole thing is new to me but there is plenty more research to be done because ketones where thought to be burned for fuel by your cells but now we're finding out they act more like signaling molecules to your cells. I'm just trying to get to the bottom of metabolism itself so I can help others solve their problems too.

A nuance in the carbohydrate model is that carbs change the way we get satisfied. If you go low carb, not only do you reduce the effect of insulin in storing fat, you also tend to be low calorie because you are not perpetually hungry.

Everyone is correct! Now, focus on where you are today and the outcomes you would like to have in 1 week, 1 month, 6 months, 1 year, 5 years, 10 years and finally your target age. Using all this beautiful information, you put together a strategy that will insure those outcomes, which will include some periods of ultra low carbs, then low calories, then food quality, then finally high fiber, high protein, low saturated fat, reasonable calories and exercise based on the body look you want to have (ripped/jacked/lean/normal/etc). Depending on the outcomes you want, your timeline and where you’re starting will dictate how much or little of all these methods you will use.

This is timely as I am in the middle of a personal health crisis where my blood pressure rapidly built up to where I could feel the pressure in my chest and throat. So I bought a BP monitor, began a 4 day fast, and visited the doctor where I learned that 207/201 wasn’t that alarming….did I want to see their dietician? I’ve been distressingly stuck, at 70+, on 95 kg for years. After the 4 day fast a week later I did a 2 day fast, and my blood pressure became less volatile and I was showing evidence of weight loss (I had to add an extra hole to my belt). A week after that I did a 5 day fast while doing my standard exercise of a daily stair climb which was for a longer time 6 stories but now I have increased up to now 20 stories. Yesterday I was able to record a BP reading of “normal” at 128/81 (79), certainly an aberration for the moment. I am eating this week and next and will do another 5 day fast in the following week. A 5 day fast starting on Sunday night and finishing on the following Friday night. That is easier to keep focus and keep track of. I am trying to eat Keto and have developed a Spinach smoothie formula that I can tolerate to pump in as much green goo as possible. I am definitely Over Weight, I definitely have a Fatty Liver, I certainly have Insulin Resistance, and have a deteriorating physical condition,….all of which I need to turn around in a short period. It seem to be working, and I am in the Lutig camp. If I can get a “Normal” BP reading 3 times each week I will have done a body rescue, and changed my habits in the process. It is very liberating to walk past all of the tempting food compulsions of the past and not be forced by habit to indulge. Still alive for yet another birthday next month.

I was watching a very interesting KZbin video yesterday by Gardner who did the DIETFITS study around 4 years ago. Conclusion of the study: Quality of the food eaten in your diet matters although that was NOT the design of the study. I.e. real, whole foods matter. It was a "low fat" vs. "low carb" study over 12 months. Peeps in both groups both lost and and gained weight independent of insulin resistance or the 3 genes they targeted. IMO, weight gain is multi-factorial with my bias being what Hall has shown in one study- that ultra-processed food causes over consumption of "calories".

Since January 2023 I've been on a diet. Initially not much happened until I downloaded chronometer and made sure I had a calorie deficit of at least a third of my recommended calorie intake for my age. I also restricted net carbs to less than 120g per day and also cut out completely all "added sugar" but didn't restrict protein or fat other than through my overall restricted calorie regime. Since then the belly fell off and I lost 5kg easily and I no longer feel tired at odd times of day. I'm 61 and walk for at least an hour every day but this has always been the case.

Thanks for taking this on Dr Physionic! The science shows you can lose weight with both low or high carb. Got it. Question: although you said that insulin is not the only player, it seems it is the more important one for those who are pre-diabetic and diabetic, true? How do pre-diabetics and diabetics fare with the high carb John McDougall or vegan route? I keep hearing from researchers like Robert Lustig that the high carbs quickly convert to sugar (especially or including the “diet” substitute sugars) that drive cravings further. Any diet studies out there specific to pre diabetics and diabetics? Those that are not just focused on weight loss, but more I importantly on insulin and blood glucose regulation would be much appreciated!

Calorie counting works, i was able to maintain the exact same weight for 1.5 years, however it does nothing to stop cravings and takes the joy out of spontaneous eating. Intermittent fasting on a high protein/fat diet has removed all cravings, delivered the same consistency of weight control and allowed me to be spontaneous.

Thank you

What about the role of muscle mass in carbohydrate storage? Mostly Unrelated: Metabolic wards don't control for the effects of diet on behavior. Portions are measured, and only the most dedicated calisthenics folks will get any exercise during confinement.

My argument has been the same for years on this. There are no fat people in starving countries. Carbs, fats, hormones will be irrelevant if you're starving. In that case you will lose fat. Fat is just stored energy.

[@veniqer]

Exactly

[@aliceclearmanphd984]

Wonderful job! What works for YOU. I agree! If a person has success, that's what matters. And there's the issue of huge serving sizes, increased sedentary lifestyles, a lot more time on screens instead of being active. Surely those things have something to do with it. Also, highly palatable prepared foods on SOOO many store shelves have to contribute to increased caloric consumption. We are eating more calories than we used to. And moving less. That has to be a contributor. "Broadly speaking, we eat a lot more than we used to: The average American consumed 2,481 calories a day in 2010, about 23% more than in 1970." (DeSilver, 2020) This makes so much sense! I kept a healthy weight on a low fat vegetarian diet - cooked my own food, baked whole grain breads, ate oatmeal - all those healthy carby foods. I carefully measured all of my foods, calculating calories, implementing a feeding window of 4 hours/day with some 24 hour fasts. BUT - I was PAINFULLY HUNGRY several hours/day - and when I went to bed. I have a lot of willpower; it was worth it to me. In COVID quarantine, my marriage failed, I grew depressed, and ate a LOT of bread - gaining quite a bit of weight. Adopted a ketogenic diet and lost that weight quite easily and I am much more comfortable with my fasting pattern. So for me, the greater satiety eating a ketogenic diet works. I'm so much more comfortable - and my IBS symptoms completely disappeared. Big surprise there. I don't doubt that genetics play a role here. They just have to. So for me, this works much more easily than when I was eating a high carb/low fat diet. That's just me. I LOVE and appreciate your work! This diet war has become tribal - makes me a bit sad.

Oh, definitely. Unfortunately, it's difficult for me to get to all the causes in one video, so I expect to cover some of these in other content, but I think your overall point about increased caloric consumption due to processed, hyper-palatable foods is my #1 target for why we are experiencing increased weight gain. Thank you, Alice!

This is the type of content I'd love to see more often on KZbin (and elsewhere): a thoughtful analysis of a debate. Most of the content is biased and promotes polarization.

[@NPrinceling]

I'm on a low carb diet, but I'm team Hall, at least based on what I've seen. Ludwig explains why there's a sudden shift towards more excitement for low carb, but I feel like it's an "easy explanation" while my diving into this, both with my experience with my own body, isn't right. There's a lot going on here, and the low carb advantage is only one aspect, and I see Hall regularly exploring these things and willingly accepting that he's wrong or surprised by results, and that's what I want to see from my scientists: not "I have the answer" but "Let's see where the evidence leads us."

[@novideostoday]

@NPrinceling I am sorry but Hall is wrong and following him will not cure any diabetes unlike low carb - insulin model.

[@barbarashirland9078]

I am a fatty. I have lost lots of weight a couple of times, once by calorie restriction only and once with carb restriction. They both worked. Now that I am old (74) it subjectively is more comfortable to eat lower carb (under about 80 grams of carbs per day). I feel more satiated on higher protein, lower carb. BUT when I eat lower carb I am also controlling calories so I am eating higher protein than I would be with calorie restriction alone. So I thought your point about doing whichever feels easier to sustain was THE most important point. All in all, obesity is a HUGE risk factor for so many chronic illnesses, it seems like getting the body fat off is THE critical piece.

Total mortality hits a minimum at about (for Americans) 10% higher weight than in the standard wight tables. Also, total mortality goes up about twice as fast for underweight vs. overweight. So, saying 140 lbs. is the standard weight for x height/age/sex, then 154 lbs = .90 relative mortality, 168 lbs = .95 relative, 182 lbs = 1.15 relative, while 140 lbs = 1.00 relative, 126 lbs. = 1.10 relative, 112 lbs. 1.32 relative (1.1 * 1.2). Numbers are illustrative, not an actuarial table.

I am an endocrinologist... I saw every diet... everything works fine .. golden rules are Little coffie 50 ml with milk when hungry Non starchy veggies with spices Whole grains as carbs protein mostly plant based (occasionally animal based if interested in it) unprocessed fat ..walnuts or peanuts or seeds (never oil not even pufa ) little calorie deficit.. weekly one day fast No alcohol or very little if must Cardio and compound strength training Finally good sleep For past 16 years i have been following people with dexa scans... it works .its easy .

[@andrewwilkins3014]

Never had an issue with weight (never had a huge appetite either) but I had to change my diet due to gut issues, so low carbs, low to no sugar. I am slowly transitioning back to see how much I can tolerate because my work outs are suffer too much. I am quite surprised how much bigger my appetite is now that I add carbs back

[@headybrew]

So these two doctors were at a convention in a big hotel. One of the convention rooms was chock full, standing room only, and they couldn't get in to see what was going on. One of the doctors said, "Hmm... It's full because more people keep going in than are coming out." And he was right. But the other doctor asked, "Why do so many people keep going in and why do they not come out"?

[@zbigniewcichosz317]

This may seem off topic at first, but read on. In 2015 Eran Segal and Eran Elinav conducted a study on benefits of sourdough bread vs white bread. They measured blood glucose levels to test which bread affects glucose less or more. ON AVERAGE they found no difference between the two. However, INDIVIDUAL results varied considerably with some people having glucose spike on white while others on sourdough. Perhaps it is the same way with low carb/ high fat and low fat/ high carb diets. IT IS INDIVIDUAL. Any thoughts?

[@PT121551]

Thank you for your wonderful presentation of these hypotheses. I actually believe in both theories. I was about 40 lb over my ideal body weight. I am 5 ft 5and I was 175 lb . I went on low carb/keto diet and I have lost 30-35lb. I’ve difficulty losing the last 5-10 lbs. I think I have to be in calorie deficit more in order to get that extra 5-10 pounds off. If I’m successful, I will try to let you know. 18:47

[@stevehunt2125]

Your best video yet.

[@alexedens1]

I’m a high protein, low-fat, low carbohydrate, high fiber guy. For me it’s simple. Foods high and protein stay with me longer. Less hunger means fewer calories. Two bagels checks in at 550 calories. An egg 72. That’s 7.5 eggs vs 2 bagels. I think it’s pretty clear which choice is best for holding off hunger longer. There are a ton of other examples. It works for me. I also exercise quite a bit. I’m 59, just a hair short of 2 m and weigh 89kg with 11% body fat. Choosing foods with the highest protein, highest mass, highest nutrition, and fewest calories works. Give it a shot.

Why is it that Europeans visitng the US for long periods of time and eating the same way so commonly report gaining 12-20lbs?

[@CharlieFader]

That’s really hard to verify, let alone make any assumptions as to the reason why.

[@martinlang9615]

All I know is that for 52.5 years I have doing SAD and peaked 4.5 months ago at 154kg. That’s when I started strict Lion/Carnivore. I reversed near cirrhosis of the liver, prediabetes, fatty liver, high blood pressure, severe cravings. Anxiety reduced, depression 99% gone. I’ve got my life back again and am so much more positive, less moody, think clearer. It’s got to be insulin model for me. However, there maybe something is a combined model that works as well as I no longer need to eat as before. So I go think insulin model is the winner, but there is something to be said for the calories in/ calories out model, but within reason and following the result of the insulin model effects. I hope this makes sense. Had I only reduced my food intake 4.5 months ago, like I have attempted before, for sure I would have had a small temporary weight loss, BUT it would have gone higher than it was before. This is exactly what happened to me to after starting OZEMPIC when at 144kg. I did lose 11kg, but when the Australian Government put a ban on it thanks to the manufacturer not keeping up supply (unsubstantiated claim as I just don’t know why I could not get my prescription filled for as I tried for a month or more) I put that weight back on and once I reached 154kg with my health getting noticeably poorer, I knew I had to either “pull the pin on life” or do something drastic. What a ride in only 4.5 months! I’m NEVER going back to the SAD (Standard American Diet)…in Australia it’s the same diet.

What is the muscle loss in these two different diets?

[@blucheer8743]

I think genetics and natural section are what is in fact paramount in whether someone will be fat or skinny. ppl from northern Norway are going be very different from ppl from the south Mediterranean area both put into the same situation and given the same food.

[@greentree_]

What fat loss diet does Physionic prefer, lower carb, lower fat, or none of those: just a balance of both (as long as there’s a caloric deficit)?

[@iancollings5047]

Ludwig, i lost 26 lbs reversing type 2 diabetes, with no intent or desire to lose wwight. I have always been too skinny for my hight. It took me 3 weeks to become fat adapted with stable ketones in the region of 1.2 to 2.0 mmols. The higjer satiety of low carb high fat and protien helped food cravings and enhanced cognition helped to stay the course as well as the health benifits of reversing long term diabetes.

[@julialerner3322]

I find that when I stick to low carb, I have more energy and clear thinking, less itchiness and bloating, and my pants fit better, but when I break down and have carbs, I get a very unpleasant candida overgrowth that causes rashes and all kinds of side effects that make me feel yucky and fat and tired.

[@bertalanronai2182]

Low Carb + Time Restricted eating solved my problems with weight loss. I have been tracking my weight since 2018 and in a matter of 4 months after watching a bunch of videos about keto, mitochondrial uncoupling and fasting my wieight went below what I had in 2018 so I can't even tell when was the last time I had this weight. My body fat is about 20%. I really enjoy these debates between different experts, scientists. I am definitely not a fitness guy who could go to the gym 3 times a week, somehow I manage to drag myself there twice a week. Sometimes I eat a lot at events but if I don't eat a lot of carbs I barely gain weight after these events.

[@DeltaMikeTorrevieja]

I like the broken GPS analogy. Imagine you have a device that tells you your distance from your goal, but not the direction to go. You ask an expert which way to go and after 40 or 50 years of following their advice you find you are further and further from your goal. At some point you have to take stock and just admit that they got it WRONG. That is the situation with food / diet science's standard model. Low fat, low cholesterol, high carb ultra processed - all wrong. Go back to historic practices. Breakfast like a king. Meat and or eggs for breakfast. Fewer cereals. Less sugar. Less ultra processed foods. 50 years of going in the wrong direction, you have to throw away the old map and turn around!
