[Music] you [Music] hey guys I’m here with Dave Feldman this guy is awesome he basically is a an outsider that can take complex subjects about cholesterol and break them down for the average person understand and what I like about you you’re a software engineer so you actually think in logic so you basically looked at this problem from an engineering standpoint you know and you actually just really figured out because as you would agree that you would think there’s a lot of science and medicine but there’s doesn’t seem to be a lot of common sense when there comes to own cholesterol there’s so much excitement around particular there there really is a sort of prevailing I I want to find a better word for this but a prevailing attitude towards cholesterol where it’s sort of a almost a near avoidance of finding good news that associate suspect cholesterol with positive outcomes yeah guys if you don’t know this Dave is going to be at our summit okay and there’s a couple little things that we’re gonna tell you right now that we can’t tell you fully but there’s potentially gonna be a release of some new information that’s quite huge right Dave yes yes hopefully it’ll be done by that hopefully I mean one of the things that I think a lot of people can appreciate is it’s kind of amazing I always think that I’ve reached an apex of the data that I’ve gathered both for my own in of one experiments and those who follow me and often I’m wrong often in fact I don’t know of a single time I’ve been able to give a presentation where at least 50% of it didn’t have to change from the last one it’s it’s very common for me to have a whole lot of new data and in particular one of the things that has been a very impressive treasure trove is this most recent experiment where I literally gained weight and in in the current phase of the weight loss period of that same experiment I haven’t actually fully lost all of the weights at a game and from because this has never actually been done before Eric and I’m pretty I’m pretty excited to be able to have done this is that we’ve never had people who’ve gone on a low-carb fever genic diet and throughout the whole process took very wide spectrum of tests and so I thought you know I’m I’m gonna go ahead and just take this shot all the time insisting that nobody else follow my shoot there’s a lot of people get inspired by my experiments but I say this is the one not to do because in order to do it you have to induce a state of hyperinsulinemia I I was adding of course a lot of carbs and fat and maintaining at such a level that I would eventually I was trying to shoot for gaining about twenty to twenty-five pounds of fat body fat yeah and and for what it’s worth you really can do it pretty quickly because that magic mix going on particularly with the high carbs I had my carbs up very very high and it you know I got 219 pounds up I didn’t actually get to the 20 to 25 but I’m okay with that knowing what I know now I definitely gathered quite a lot it the primary purpose I was going for actually came back to cholesterol what I was trying to do is I was trying to see as many people see themselves when they go on this diet and that had much higher levels of body fat you may actually have lower relative LDL cholesterol the so-called bad cholesterol then you do as you actually lose a lot of weight so I wanted to both know okay does your LDL cholesterol go up as you’re losing weight and also does your LDL tend to be lower relative to what your LDL cholesterol would be at when you are at a lower rate if you say stall so I actually had hoped to have stalled right at the top right the peak there so that I can make that comparison as it happens I didn’t almost as fast as when I switched over to congenic diet again the weight started coming off right away but I got to answer that one question which is as ldl-c indeed go up as you lose weight and I can share that with you now yes it does nobody has as pristine a dataset as I do I literally hit my hundredth blood draw I want to say a week and a half ago and in in doing so I have practically a mapped metabolism like I could I joke about this but I’m gonna probably do it at some point I literally could get from you I could have you write down a number between 100 and 350 and I could move my LDL cholesterol to within 20 milligrams per deciliter of that number in like a week like I’ve got it mapped out to that degree without any supplements or medication off Wow yeah it’s in a bottom line is without question they can’t keep this data down for too long there’s no single larger influencer on your cholesterol levels no single larger one then your metabolism particularly your energy metabolism and if you’re powered more by fat then you are powered more by triglycerides carried in the LDL boats if you will and those boats eventually get remodeled to LDL particles now there’s some individual variability between those but that’s how I’m able to accomplish that well the value of that is that I’ve gotten later into these phases of experiments to where I could do this one which is I could say okay well now that I know what my LDL cholesterol will be at roughly when I’m at a lower weight if I already gain weight I can see what would happen to it on the way up and I could see what would happen to it on the way down but why stop it cholesterol why not also take a whole bunch of other tests people would not normally take especially at the switch off what would be for example my inflammatory inflammatory markers like il-6 like ferritin my c-reactive protein of course like what happens to all of these is it changes on top of that I got a lot of physical metrics like for example I got respiratory quotient as we actually had the face mask on you’re actually checking how much you’re burning sugar versus burning fat so I’ve got that map down but the most explosive data that I can also share with you now it’s been my it’s something called a carotid to media thickness test we you yes you you actually what you do is and you may already be familiar with this it’s an ultrasound that you get on the common carotid arteries on the left and right side of the neck and I’ve been getting it about every six months starting and I want to say mid-2016 so about a year after I’d started keto and at that time I was at a very high risk level which definitely surprised me but with each of the six months both my left and right side regressed more and more regressed so it’s supposed to actually slowly increase with your age but while I was here genic I was slowly actually thinning it on both sides the right side was thicker and had dropped about a hundred and fifty nanometers and the left side was thinner but actually had dropped another 50 itself and they came to within one nanometer of each other’s size by November of last year Wow okay so here’s where we dropped the bomb what then happened after I did this standard American diet experiment right would it have started moving in the other direction I certainly was speculating a lot on that publicly and I was saying well I wouldn’t be surprised if it did hopefully it doesn’t do it by a lot and Eric I’m here to tell you that it did go by a whole lot it actually went to the highest on both sides Wow yeah oh my god fact the right side which had had 150 drop actually moved up I want to say a hundred and sixty 170 so it was technically the highest on that side and the left side which had had something like a 40 or 50 nanometer jock had moved to the highest on its side crossed 600 for the first time so when I had been insisting nobody else followed my suit this high yeah I not only I not only feel strongly about it now but on top of that I tell everybody I know hey you know how you’ve always had like a relative or you yourself
