Muscle-Building Workout and Diet


So, my name is Dr. Paul Mason, I’m a sports and exercise medicine physician and today I’d like to take you all on a journey exploring the science that underpins low carbohydrate diets and in the process I’d like you to take away a few things. Firstly We wanted to debunk the “calories in calories out” low fat hypothesis of weight loss. I want to demonstrate to you that a low carbohydrate diet is actually good for longevity People live longer when they eat low carbohydrate And sugar because of fructose has some particularly unique and toxic effects on the body So to begin our journey, I’d like to introduce you to one of my patients Now this is the kind of patient that as a doctor. I loved she was very very compliant So she first came to my clinic with joint pain And she was overweight and it was very clear to both of us that if she could lose some weight that would help her condition so we had a conversation and started talking about her existing attempts to lose weight and it seemed that she had a very conventional approach the kind that is recommended by most doctors: eat low-fat So let’s hear her account this in her own words And I was doing all low fat you were to see my fridge was just full of low-fat cheese No oil touched any frypan in my kitchen all the meat was as lean as you could possibly get and I ate salads and I was starving all the time and were you exercising Oh madly six days a week and I was doing those classes. I was doing back-to-back classes. So an our hit classes followed by a pump class and Six days a week. So and then I felt really guilty on the seventh day Because I wasn’t exercising So She was following the conventional advice She was slavishly following that advice. She was exercising She was eating low-fat, but the trouble is it was not working. At the time she saw me she was 30 kilograms overweight and gaining. So When I’m faced with this scenario as a doctor, I have to ask myself ¿Who is responsible? ¿Who is to blame? So the patients following the medical advice that they’ve been given So is it the patient or is it the doctor or the medical professional who gave the advice? So I would argue the blame should actually lie with the doctor or the health professional because the implication of the advice is that If you fail to lose weight You’re lazy and you’re greedy You’re just not trying hard enough But this very premise overlooks the key essence to understanding weight loss and that’s hormones The conventional “calories in calories out” hypothesis ignores the effect of hormones very a very strong science So we’ve got a lady here. She’s 35 years old and she’s got a problem with a hormone called cortisol, and she’s just been gaining weight And this is what happens when her hormone problem was treated she didn’t get given advice to exercise more She didn’t get told to eat less. We fixed the hormone problem and the weight problem goes away This boy here three years old. He weighs 42 kilograms and he’s got a problem with a hormone called leptin Seven years old he now weighs 10 kilograms lighter and a very healthy weight See what happens when you fix the hormone problem Now the most common hormone in the population that causes obesity Is not one of those, it’s called insulin and this lady has a problem with insulin, but she’s got a unique problem She’s got a tumor in her pancreas that secretes insulin And pumps it into her circulation in this picture. She’s a 107 kilograms and she’s only 152 centimeters tall So she had an operation to remove the tumor which lowered the insulin levels in her body Now these photos were taken 50 days apart Her weight dropped to 89 kilograms. She lost 18 kilograms. And if we have a look at a graph of her weight loss You can see that in a 10 day period she lost 14 kilograms So clearly there’s a problem here with insulin. It makes you fat Now this patient also had a problem with insulin. This was one of my patients you can see her here 46 years old and a size 20 This is what happened when we fixed her insulin problem, she lost 40 kilograms and Here she is about a size 8 The big difference is she didn’t have surgery to fix her insulin problem. We changed her diet So you’re probably asking how on God’s green earth can a diet lead to such dramatic Changes in your insulin level that you’ll lose that much weight. So let’s have a look. This is a graph here And the height of the lines there represents how much insulin your body is releasing And each of those individual lines represents one of the three main sources of energy in our diet: Carbohydrates Protein or fat So let’s have a look at carbohydrate. Let’s see what happens when you eat carbohydrates to your insulin levels this is called the area under the curve you get a massive and prolonged release of insulin for over two hours let’s have a look when you have the same amount of energy contained within protein much less And the surprising thing for many people Fat is even less. So think about that for a moment high levels of insulin are associated with obesity and Carbohydrates are the most potent stimulus we have on our bodies to release insulin So in order for us to lose weight, we need to control that insulin level ergo We need to control our carbohydrate intake Now we can broadly classify Diets into one of two groups on the left here We have what’s called low carbohydrate diets and on the right We have low fat diets, which tend to be higher in carbohydrate Because the energy has to come from somewhere So let’s have a look an unbiased look at the evidence Comparing these two types of diets in terms of weight loss Between 2003 and 2018 There were 62 published randomized control trials comparing low carbohydrate diets less than 130 grams a day to low fat diets in terms of weight loss 31 of these studies had statistically significant findings what that means is That the results were not likely due to chance You could probably trust them So what I’ve done here is I’ve graphed these 31 studies that had statistically significant findings No cherry-picking here at all. And I’ve compared the average weight loss on the both diets the low carbohydrate diet is depicted in blue and the low fat diet is depicted in red And you’ll note that in every single one of these studies that we’ve got here the low carbohydrate diet Led to more weight loss than a low-fat diet So the question is which horse would you back? Now let’s Change pace a little bit and have a look at fat and see exactly how insulin makes fat tissue grow Because if we understand this we can understand the cause of obesity, by the time you’re 2 years old You’ve got every fat cell that you’re ever likely to have So if you gain weight after the age of two It’s because your fat cells have gotten bigger not because they’ve multiplied So if we can work out what makes an individual fat cell bigger then we can determine what makes you fatter so what I’d like to demonstrate here is that you can see how the circulation, these blood vessels are intimately related to each and every fat cell now we understand that hormone Is released in through the circulation and because of this relationship with the blood vessels It can be delivered to each and every fat cell in our body and these blood vessels also contain fat called triglycerides You can see here in these These wiggly line depictions down there. So what happens to gained weight Is that these triglycerides Get transported into the fat cell and the fat cell gets bigger. The problem is this triglyceride molecule is very big It’s composed to four different parts You’ve got this glycerol backbone, and then you’ve got three Separate fatty acids and as a whole this molecule cannot enter into a fat cell It has to be snipped up first and that’s where insulin comes in So what you can see in the left-hand side we see the triglyceride molecule and then it’s being converted to glycerol and fatty acids it is being snipped up and the LPL transfer lipoprotein lipase This is an enzyme that is stimulated to act by insulin And then once the fatty acids have been released they’re able to cross and store fat without insulin to activate Lipoprotein lipase you can’t store fat. And if we have a look on the top there you can see glucose can also enter fat cells and it does this through a little doorway or a transporter called the glute 4 transporter and again insulin is what activates this transporter once the glucose is inside the fat cell it gets converted to glycerol then the glycerol will then combine with the fatty acids And then you’ll have a complete triglyceride molecule. This is the storage form of fat Now to add insult to injury if you want to actually burn that fat it has to be snipped up again to leave the fat cell because as you know, It can’t cross the fat cell membrane and to be snipped up. It has to be activated by or Cleaved by an enzyme called hormone sensitive lipase Insulin turns this enzyme off So you end up with a triple whammy you have lipoprotein lipase and the glute four transporter being activated that’s stuffing fat into the cell and And then you have hormone sensitive lipase being deactivated so that you can’t burn the fat so insulin biochemically is the cause of weight gain, So for a final proof that insulin causes weight gain Let’s have a look at what happens to people who habitually inject themselves with insulin in the same site over a long period of time It leads to a condition we call lipo hypertrophy Hypertrophy meaning get bigger now these two On the left and on the top right These two gentlemen injected insulin habitually into these sites in their lower abdomen over a long period of time the person on the bottom right their preferred injection site was on the front of their thighs about twenty to thirty percent of patients with type 1 diabetes Will actually end up with this condition because they inject insulin high enough doses for long enough So whatever happened To my perfect patient, you know The one who was slavishly following the low fat exercise advice before she saw me was thirty kilograms overweight Well, we had a discussion She cut the carbs out of diet and she increased the fat and by doing that she fixed her insulin problem And then this happened At last count three years later She’s maintained a loss of 36 kilograms and she lost 28 centimeters off her waist and these are her actual photos. So Let’s have a look at what is it about carbohydrates that can lead to this increase in insulin that causes Obesity. So begin to understand we have to have a look at what carbohydrates are on the top here we have a molecule of glucose and Across the middle there. We have a depiction of what we call a complex carbohydrate You know the kind of carbohydrates you’re getting brown rice and whole grain bread the stuff that you’re told is good for you It’s made of glucose is sugar Carbohydrates are made of sugar and when you eat them and digest them they end up entering the bloodstream To increase your blood glucose level When you saw Rod and he decided to have some rice The glucose that made that rice up entered his bloodstresm And in response to this increase in blood sugar the pancreas this organ tucked up in our abdomen here release something called insulin And then the job of this insulin is to remove the sugar from our circulation it puts it preferentially into our muscle tissue and our liver tissue and then if there’s any leftover that gets stuffed into the fat the problem is that if you have high insulin levels for long enough that create a condition called insuline resistance Se we know that when you eat carbs you get this masive spike of insulin and if you do that habitually six times a day As many of you have probably been recommended to do your body becomes insensitive To the high level of insulin. It’s like when you walk into a room with a bad smell At first its overpowering and after a few minutes you don’t notice it anymore It’s the same with insulin Except it only happens mainly at the muscle and the liver tissue so they stopped taking in the sugar Your body compensates by releasing more insulin and then the body is able to stuff that extra sugar into your fat tissue so this actually explains why a lot of people come in and they say You know what when I was 20 I sat on the couch eating potato chips no exercise and I was skinny and as I’ve gotten older I’ve just gradually stacked on the kilograms and this is despite becoming Health-conscious I now go to the gym three days a week. I now eat salads So the reason that they’re gradually gaining weight is because over the years and this happens over 10 15 or even more years They’re becoming insulin resistant And we can actually test for this so in my clinic with my patients We do a test where patients will drink 75 grams of glucose And then we mesure their glucose levels and insuline levels Over the course of a 2 hour period And We can actually assess their level of insulin resistance based on the results. So let’s have a look So in the red here this represents insulin level and the blue line represents blood glucose level So this is somebody who’s metabolically healthy. We give them the load of glucose and two hours later We’re having a look They say that blood Sugar’s not elevated beyond what it should be and the blood insulin is not elevated beyond what it should be perfectly healthy Then in the first stage of insulin resistance or metabolic i’ll health you’ll note that inlsuline level starts to creep up But it’s still doing a good enough job of keeping the sugar out of the bloodstream So the blood sugar is not yet elevated if you had a blood test a standard oral glucose-tolerance test done at this stage Your doctor would tell you you’re perfectly healthy. Don’t worry go home you are fine And yet you’ve got the first signs of insulin resistance. You’ve probably already gaining weight at this stage as it progresses And it starts to creep up a little bit. The insulin goes even higher and this stage is where your doctor would say: oh you’re pre-diabetic you know, have you thought about doing a little bit of exercise? still not too worried about the whole process And then over time this blood sugar starts to damage the cells in the pancreas That release insulin so even though you’re becoming insulin resistant and you need more insulin your body produces less And then when your insulin levels start to fall you have a precipitous increase in your blood sugar levels, and that’s when diabetes is diagnosed So let’s have a look at a couple of examples So this patient here low blood sugar low insulin level Perfectly healthy. I like this comparation This patient here probably putting a litle weight You can see the blood Sugar’s quite low at two hours 5.6 but you can see the insulin has now risen to 83 Okay, we’re starting to see insulin resistance here. We’re starting to have a problem And here you can see that blood sugar has now come up of the floor insulin is a bit higher again and the blood sugar is rising to 8.3. And then what happens in the more advanced stage? Blood sugar 11.4 this is when you would be diagnosed with diabetes under standard blood tests, by the way, And the insulin level has dropped the pancreas is starting to fail Now it’s all well and good to say, okay you’re a doctor you can test for insulin resistance in your laboratory but a lot of people are curious to know if they have insulin resistance And whether they can check themselves and you’ll be interested to know that you can see a lot of signs of insulin resistance by looking at the skin And I’ve got several patients here today and you know that i’ll inspect your skin These are what’s called skin tags The most common cause of skin tags it is insulin resistance If you have skin tags You are almost certainly insulin resistant And a lot patients tell me Well, I go to my GP and ask what causes it they say in one sentence I don’t know, but would you like me to burn them off? They’re a warning sign They’re usually in the armpits around the neck in the groin region This sign here is called pay can ptosis nigricans it’s Pigmentation of the skin we often see it around the neck in the armpits in the groin Or more interestingly on the back of the fingers The skin creases here and there’s good research that shows that even before you start gaining an excess amount of weight You can see The changes on the back of the fingers before anything else. I can see a few people having a look at their fingers now I see a lot of patients who come in with problems with their skin complexion and what we find is that when we improve the insulin resistance that Significantly improves have a ketogenic diet lower your insulin levels skin gets better. It’s very nice. And that’s one of the reasons why Acne is very common in the state of adolescence because the state of adolescents puberty is associated with insulin resistance Now for the good news that had to be coming We can actually reverse this If you go on a low carbohydrate diet and reduce your chronic elevated levels of insulin your insulin sensitivity will improve have a look at the insulin levels of this patient here and three months later big drops Here’s another example we can see that one hour insuline he was 114 an again to 71 just in the space of a few months An there is also a nice asocieted weight loss to boot So, I think it’s pretty clear A low carbohydrate diet is the best diet for weight loss But some of you are probably still concerned you probably thinking well, it’s all well and good to be skinny But what happens if it’s going to kill me all that saturated fat, right? so let’s have a look at the Bigest study that’s been done to date on this topic. It was published last year And it had over 135,000 participants they were followed for more than 7 years across 18 countries. This was a big big study So what we can see is that the group that was having the least amount of fat had a mortality rate per 1000 person years of just under 7 Let’s see what happens to the group that was getting more of the energy from fat more than 3 times as much from fat their mortality rate dropped at 4 more fat live longer and if we have a look at a graph from that same study demonstrating this where your risk of dying Is on the axis going up the higher the worse it is and the effect you’re having is going to the right hand Side and you can see there’s no point at which having more fat becomes problematic in actual fact It seems the more fat you have the total mortality continues to drop So now let’s flip this on its head and have a look at carbohydrate intake if you have 46.4 percent of your energy from carbohydrate the mortality per 1000 person years risk was about 4 And by the way, this is not considered a particularly low carbohydrate diet, but it’s low Carbohydrate compared to the average diet. Let’s have a look at the group of the population that was getting far more 72.2 percent of their energy from carbohydrate their risk of dying went from about 4 to over 7 With more carbohydrates. And again, we have a look at this graph the more carbohydrates you have your mortality just keeps on climbing So low carbohydrate high fat diets you will live longer Now this is not a one-size-fits-all diet Some people might be able to have 80 grams of carbohydrates a day Rod says his limit was 50 Some other people may only be able to have 20 grams of carbohydrates a day to be in optimal health And we use something called the ketone meter to determine your optimal level of carbohydrate restriction now the only difference between a low carbohydrate diet and a Ketogenic diet is the degree of restriction of carbohydrates If you reduce your carbohydrates enough to lower your insulin levels to permit fat-burning Some of that fat when it’s metabolized will be converted to a chemical called a ketone Now the thing to realize is that in the human body. The only source of ketones comes from fat metabolism nothing else So if you have ketones in your bloodstream that indicates that your body is burning fat So we can take a drop of your blood put it on a meter and within 10 seconds We’ve got the answer now down the bottom. This is the scale that we generally use and it’s also useful As well as indicating your degree of fat metabolism For suppressing your appetite what we find in the clinic is over The last few years is that people who come in with ketones hovering around point 4 or higher. They often say you know what I’ve only eat twice a day now, I’m just not hungry And this is demostrated in the research we know when you have higher levels of ketones that has an apetite supresing effect So not only Are you burning more fat But the whole “calories in calories out” first law of thermodynamics equation you put less energy into the system So this actually dovetails in quite nicely with the conventional wisdom of “calories in calories out” But it adds another layer. It starts to explain how you can put less calories in so This is an example here of a food diary with ketones being recorded down the right-hand side the numbers down the side and the reason we do this is because By recording your ketones and comparing it to your food. You can actually start to understand which foods are stopping your burning fat let’s zoom in a little bit so we can see down the right here. We’ve got a few ketone numbers 1.1 that’s good 0.7 That’s okay. 0.4 That’s still okay, and then we drop to 0.2 why? A small piece of sponge cake, okay Probably not the best But it’s ok because the next day they’re back up to 0.7 Piece of toast Bumps it down to 0.2. This person is very very sensitive to carbohydrates And without doing this They would never have known so now I’d like to take a closer. Look at sugar and the uniquely toxic effects that that has So we’ve already seen about this glucose molecule on the left the one in the yellow But the one on the right is called fructose and when you join one of each of these molecules together it forms table sugar, sucrose and you can see that it’s Sucrose is exactly 50% fructose And that’s important because a lot of people say we don’t have a problem in Australia because we don’t have high fructose corn syrup well high fructose corn syrup is only between 42% and 55% fructose So they’re very very comparable the table sugar we have here in Australia is every bit as bad as high fructose corn syrup Now When we have a look at the swetness of diferent sugars the reason fructose is a problem is it’s more than twice as sweet as glucose and And this is a problem Because as humas we love self-gratification We’ve got this pathway in the brain called the mesolimbic pathway and this is the reinforcing pathway reinforces our behaviour And when we stimulate our brain with something sweet we get a release of a chemical called dopamine and it says yes do that again and fructose Activates this pathway by virtue of it being more than double the sweetness of glucsose It activates this pathway more strongly And when we sacan the brains of obese individuals And have a look of dopamine receptors we can see there’s a reduced number Of dopamine receptors in the brains of obese people. So this means to get the same level of satisfaction from a meal Obese people need to eat more And this is where sweetness fits into it. Over time this changes will down regulate But the problem is that untill they down regulate over time you have to restric the sweet foods in your diet Now fructose has another particularly toxic effect and that Leads to insulin resistance Fructose far more powerfully than glucose leads to a fatty liver So when you eat fructose Normally about 80% of it gets taken up by the muscle, gets taken up by the liver and then It goes to the liver and there’s a capacity for storage in the liver for glucose has something called Glycogen so that sets up a little bit more So the amount of energy that ends up going to the liver and going to the mitochondria within the liver Is only a fraction of what you ingest but with fructose it doesn’t go to the other tissues and it doesn’t have this reservoir where it can be taken up or stored so Every gram of fructose you eat gets delivered to the mitochondria in the liver. And when those mitochondria get overloaded They produce fatty liver Process called DNA vapor Genesis. This is a slide those white globules There are globules of fat in a fatty liver and excess fractose can do that and this is strongly associated with insulin resistance Another problem is that Sugar can attach to protein And you’ve got sugar Bathing the cells of your body and that sugar over time Can not only attach to it that can form these Complexes called advanced glycated end products and they can affect nearly every type of cell and molecule in the body the problem is That fructose does this seven times more than glucose Yet another problem with fructose And when we have a look at the consequences of these advanced glycosylated end products They affect a lot of the tissues that we see people with diabetes have nerve problems we’ve already talked about how the pancreas can start to fail and Reduces it’s capacity to secrete insulin kidney problems, blood vessel problems You can go blind arthritis is really really comon Now just to illustrate the point That these advanced glycosylated end products are associated with aging this is some ground-up rib cartilage on the top left This is from 2 weeks old and on the bottom right from 88 and this is what normally happens across the lifespan It’s very similar to a process called the Maori action on the Browning reaction caramelization if you will not quite the same but along the same lines and over time The sugar in our circulation will change Our tissues and I’d have a question. Why would you want to accelerate the aging process by increasing your sugar levels even more? now We know that the most common sources of added sugar in our diet are sweets Maybe some people be surprised to know that cereals is one of the major courses of added sugars in our diets But sugars are also hidden in a lot of foods Not many people will realize that a squirt of tomato sauce probably Far less than what they actually habitually put on as good one of the health teaspoons of sugar in it But the real surprise is down on the bottom right here. This is a medium-sized mango juice 12 and a half teaspoons of sugar and There’s other ways that sugar can be hidden. I’ve got an organic almond milk here. Perfect You can see lactose free soy free. Gluten free no cane sugar. Okay, you’re feeling pretty good right now Let’s have a look at the ingredient Still look okay? Show our hands who thinks it doesn’t look so bad organic agave syrup you know agave syrup is 75% fructose it’s even worse than table sugar. It’s worse than cane sugar And this here is a list The names That sugar is disguised in in Australian nutrition labels Food manufacturers are allowed to use every one of these euphemisms of sugar on their label makes it very difficult Now some people say but fructose it’s natural, right Maybe it’s natural, but we don’t consume it in a natural way You wouldn’t know it but this is a fruit tree on the left. It has no fruit. It’s because fruit is seasonal We don’t have access to fruit year-round and if you want, honey Well, you don’t get to go to Cole’s traditionaly You had to go and ask the bee if it would line if you had his honey So we consume fruit in a very different way. We now have 500 mils of orange juice which contains 6 oranges And it’s had all the fiber taken out So just as an aside, don’t drink your fruit. Just do not drink your fruit Now I’d just like to touch on one more point before I finish and that’s artificial sweeteners So we’ve already talked about them as a Olympic pathway reinforcing behaviors and Artificial sweeteners do exactly the same thing when we have a look at the evidence all the cohort studies They show that consumption of artificial sweetness is asociated with weight gain Increase weight circumference metabolic syndrome type 2 diabetes and heart attacks artificial sweeteners don’t get a leave pass So, I’d like to leave everybody here with three key points Number one: You are not to blame for being overweight if you’ve been folloing bad advice Critical Number two: low, carbohydrate diets are the best diet for weight loss because they lower insulin and finally people live longer on low carbohydrate diets Thank you

100 thoughts on “Dr. Paul Mason – ‘Low Carb from a Doctor’s perspective’

  1. This is an excellent talk. Proves beyond argument that a high fat diet is a killer. Many of us baby boomers now in our sixties plus were brought up to believe the sugar industries lies and manipulation of so called impartial scientific studies (paid for by the sugar industry) that fat was the cause of obesity. This talk should be compulsory watching for people trying to loose weight and not achieving any weight loss.

  2. I would like a little more detail on the morbidity study: my first thought was, Did the high calorie group have a higher mortality rate because they were generally poorer?

  3. I’ve started my own diet similar to keto and I have lost 1st 1/2 in six weeks. I have more energy too, the hunger is not there. Carbs are fine in low levels but I think it’s mainly the sugar! That’s my experience anyway.

  4. Thank you Dr Mason for your clear presentations

    I have a couple of questions:

    1) Does the Ketogenic diet increase acidosis?

    2) do we have any evidence on Lyme disease and coinfections being a factor of disturbance of cellular metabolism, insuline resistance and glucose intolerance ?

  5. Does this mean that insulin injections could be used as a breast augmentation method? Or would that be a major health risk?

  6. incredible video, explains so much, my only concern about this whole thing of the keto type diet is the saturated fats being ok to consume, it's something my doctors have been warning about for years, also will this type of diet give me enough energy for long duration mountain bike rides 100km+ etc?

  7. 29.28 Cyanide is 'natural' too, it is found in substantial amounts in certain seeds and fruit stones, e.g., bitter almonds, apricots, apples, and peaches…

  8. Excellent and easy to understand presentation. If you are interested in gaining knowledge about a low carb, high (quality) fat way of eating and living, then you should watch (and share) this video and view Dr. Mason's other work.

  9. Biggest problem I see with this guys videos is like everyone from the 1970’s says all carbs are the same. And therefore let’s just add sugar for carbs, and take out everything healthy and if you eat carbs you might as well be eating high fructose corn syrup.

    In the 70’s that’s what happened they tried to replace fat with high fructose and free sugars and health today is what we have to show for it . It only makes sense that people who are sick would rebel and come up with a contrarian philosophy. Yes free sugar is the problem. But all carbs are not created equal. 🤦‍♂️

  10. U can test this eat a boiled egg with sea salt and a half avacodaand ser how full and satisfied u are
    It's not the doctors is the schools and u know that mr doctor

  11. The medical and pharma industries dont want answers they want to sell more appointments and drugs and surgeries healthy patients don't buy beach houses sick people do Medicaid do

  12. Dr Mason is comparing the "Standard Australian Diet" (SAD diet) to a low carbohydrate diet, and finding that the low carb-diet is superior, and leads to weight loss, and the remission of type1 diabetes. This is true.

    But the SAD diet (high fat, high processed food, low fibre, high sugar, excess calories, low phytonutrients), is an appalling diet, responsible for a raft of common diseases, including heart disease, osteoporosis, arthritis, diabetes and cancer. Almost any variation of the SAD diet might be an improvement.

    Multiple well-regarded studies show that a low-carb ketogenic diet as recommended by Dr Mason is responsible for many health problems. In particular the high animal protein content of a typical low-carb diet is heavily implicated in cancer, heart disease, and osteoporosis.

    Further, the claim that insulin resistance is caused (alone) by sugar has been seriously challenged. Current research heavily suggests that insulin resistance is mainly occasioned by fat blocking the cells.
    So while "counting carbs" gives temporary relief to the diabetic (no carbs means no need for insulin), a low-carb diet is a Highway to Hell, in-as-much as you are still ingesting high fat, and continuing to block the cells with fat. (Albeit less fat). The diabetes will still slowly progress. And you are also laying the ground for heart disease and cancer and osteoporosis..

    Despite decades of research, the basic mechanism of T2DM is still not well described.
    Until the bio-chemistry is better understood, we will have to also look to the epidemiological studies.
    Dr Mason's clinical work shows some positives; but he does not allude at all to the multiple well-structured studies indicating serious health consequences caused by a low carbohydrate diet. Why not?

    For a balancing view, I recommend referring to Dr Neal Barnard, Dr Caldwell Esselstyn, Dr Joel Fuhrman, Dr John McDougall, The China Study by Colin T Campbell, and others who are highly critical of the low-carb pathway, and who have had long-standing clinical success with a higher-carb "whole-foods, plant-based" approach. This approach is also sustainable in the long-term. Hunger is not a problem, and reversal of many diseases (including heart disease) is possible.

    It may not have escaped notice that an unnatural state of continuous ketosis, (necessitating heavy meat and dairy consumption) is not a diet that would have been available or consumed by early (evolving) man.

  13. When you say the word fructose, Doctor, are you referring also to the fruit sugar in apples, berries, melons and the like? Or just to sucrose and high fructose corn syrup? Help!

  14. Do you refer to the Seven Country Study at 20:10 ? That study is criticized to be heavily biased due to statistical flaws in the questionair and Ancel Keys methods. What is your opinion??

  15. I've been on a low carb diet for three years, absolutely the best thing I've ever experienced. I only wish I had known about 20 years ago. We need to get the truth out, great video.

  16. This is perfect for those people that base their diet decisions on trends or assumptions but have never looked at the science of it all. I was included in this group and still am TBH. Understanding medicine and understanding chemistry are not synonymous. Your doctors can be wrong if they’re using generic concepts rather than actual science in their advice.

  17. 7:50 to 10:52 excellent ‘triple whammy’ explanation of how insulin makes us store fat! Thank you Dr. Paul Mason.

  18. Ive been taking 2 litres of that almond milk every day thinking it is good for me, low kilojoules but I was constantly getting cravings. >_<.

  19. Outstanding lecture…well explained for A layman like me..
    Thank you and to ethical doctors for passing on this life saving message(s)…

  20. On a ketogenic diet, lost weigh, rarely feel hungry, feel fitter and better. Thank you, Dr. Mason for the science underpinning it.

  21. This has to be one of the best and logically thought out explanations of the effects of carbs and insulin. Well done Dr Paul Mason!!

  22. Same for me… I never lost a single microgram of weight doing conventional "healthy eating", but when I go with reduced carbs, suddenly I lose weight like crazy and feel like a boss at the same time (super healthy, happy, etc…).

  23. Great video! Guys please join us for the world's first ever Carnivore Retreat. You can also buy raffle tickets to win a free trip https://www.eventbrite.com/e/100-carnivoreand-beyond-tickets-51129024288

  24. I started keto few weeks ago, and until now i am doing pretty good.
    However, all these videos present a picture of this diet that looks to me "too good to be true".

    Do you have any video of a competent person about the shortcomings of keto?

  25. can anyone point me to a simple list like 1. Things you eat. 2. Things you don't eat. Please?
    Pears for example.. can i eat them? as i understand, besides the sugar, pears are a carbohydrate.
    I'm confused.

  26. Brilliant explanation of mainstream diet problems to the lay person.
    I have been researching low carb, keto etc for weeks and this is the most interesting, thought provoking video Iv'e seen.
    Bravo Dr Mason!

  27. thus is a load of rubbish …you can not tell people that hoid quality unpricessed carbs increase weight via an insulin response ..thats not true ..just as there are bad fats thete are also bad carbs ….i eat a high carb unprocessed foids such as beans lentils fruits abd vegetables and ive lost 11 kg in 2 months ..i did keto and my lioids went thru the roof ..mnew research also suggests that low carb diets are deteimental to mental helth and many hormonal functions in the body ..ketosis is only a back up system ..the orefered fiel of thr body is good quality unprocessed carbs .

  28. Thanks Dr Paul Mason, these videos are gold. You present real research in a way that our family can understand. I’ll look out for your next public lecture in sydney!

  29. Glad some doctors have finally realized that your textbooks were produced by processed food companies that stuff everything with fructose and kill their customers.

  30. Fructose has unique toxic effects on body. Joints pain can be helped by losing some weight. Doctors give a wrong advice of eating low fat. People starve on low fat and don't still lose weight. Who is responsible? The doctors!

  31. CICO (calories in, calories out) advice ignores hormones. Cortisol aids weight problem. Leptin is another problem causing hormone. Insulin is another weight causing hormone. Fix the hormone problem, fix the weight problem! Diet changes help with the insulin problem. High level of insulin are caused by carbohydrates.

  32. Actually doctor, Italians and Japanese people live the longest and they eat breads, pastas and lots of rice! Lol.

  33. I enjoyed reading the comments section, lol. Yeah, go high fat and protein and enjoy your heart attacks and strokes! Lmao!

  34. I can break every rule you propose in a very major way and still be slim and fit
    You cant explain this .. but I can
    CONCLUSION : I know better than you do

  35. that example with the woman not loosing weight is bullshit. she was still eating more calories then she was burning in a day. I never saw anything about weighing all the foods and tracking every calorie to know she was actually eating low enough calories. I don't buy this at all. No actual proof or data saying these people eating carbs was what caused them to gain weight it was simply they ate too many calories.

  36. I would like to know how to contact Dr Paul Mason.
    I have a unique question to ask him.
    I have hereditary Hemochromatosis and insulin resistance and with those a high protein diet will put me into oron toxicoty. I cannot do blood phlebotomy due to the issues with my micro, collapsing, rolling veins which makes even regular blood draws needing a infant butterfly needle difficult. I also weigh 102 kg and need to loose weight. The doctors in the USA and Netherlands has been of littke help. I need an answer. I need serious help…. my life is on a tight rope and all the searching for answers since the age of 25 has made me broke and my conditions has caused seizures and other heath issues that made me dusabled. PLEASE HELP AS I FEEL THIS IS GOING TO BE THIS 53 YEAR OLD WOMAN'S LAST CHANCE IN NOT DYING!

  37. Gary Taube took the medical establishment to task for this 12 years ago in his book "Good Calories Bad Calories". Very interesting information about skin tags. That's totally new to me.

  38. Absolutely excellent! This presentation lays out the fat story better than any other i've seen. It is life changing! Great job Dr Mason!!

  39. When water fasting, blood glucose drops to mid 50s the second day and stays there for weeks. All from body fat.

  40. DOES BLOOD TYPE HAVE AN EFFECT ON DECIDING WHETHER TO GO ALL CARNIVORE OR NOT??????????? IS GOING ALL CARNIVORE GOOD FOR ANY BLOOD TYPE??????????????????????

  41. Why are there no keto-advocates over 100 years old? None, anywhere in the world. "Dr Paul Mason obtained his medical degree with honours from the University of Sydney, and also holds degrees in Physiotherapy and Occupational Health. He is a Specialist Sports Medicine and Exercise Physician" Yet, he is simply regurgitating others beliefs, not his findings. So, it's not his perspective he is presenting, its others perspectives. He has also 100% ignored the evidence at hand in the Blue zones and in the towns and cities where blue zone diets have been implemented. None of them are high fat, indeed they are all low fat. Some may say this Dr is, therefore, naive. He has cherry picked the datasets, there are MANY other studies he hasn't included.

  42. I’ve been on Keto for 2 months now and am down 8 kilos. I have been following Dr Berg on you tube and Dr Paul Masons name was mentioned. Nice to see a Dr here in Australia who understands Keto. Are there many Drs here who do? I would like to find one.
