Transcript

00:00:00.000 Hey everyone, welcome to a sneak peek, ask me anything or AMA episode of the drive podcast.
00:00:16.500 I'm your host, Peter Atiyah. At the end of this short episode, I'll explain how you can
00:00:20.460 access the AMA episodes in full, along with a ton of other membership benefits we've created,
00:00:25.440 or you can learn more now by going to peteratiyahmd.com forward slash subscribe.
00:00:31.140 So without further delay, here's today's sneak peek of the ask me anything episode.
00:00:39.260 Hey everyone, welcome to a special ask me anything episode. And when I say special,
00:00:44.840 I am not kidding. You'll see why in a moment. This is going to be part of a two part series
00:00:50.800 with Dom D'Agostino. Now, some of you may know Dom's name as he was, oh, I don't know,
00:00:56.220 probably our fifth guest when this podcast kicked off in 2018. Dom's episode to this day remains one
00:01:03.000 of our most popular episodes. And it's for that reason that we decided to go back and bring him
00:01:07.920 back on in the format of a Q and A. We had this interview scheduled for a long time. And right
00:01:14.060 when it was scheduled to happen, something came up, something very important came up where I had to
00:01:19.620 go away. And I had to go away such that I couldn't actually do the interview. We all powwowed and
00:01:25.660 contemplated, should we reschedule it for a little while? Dom had already set aside the time to do it.
00:01:30.620 And in the end, the consensus view was why not have Bob Kaplan, who many of you know from this podcast,
00:01:39.040 why not have Bob do it? Bob and Dom already have a great rapport. There's probably nothing here that
00:01:43.900 Bob would do that I wouldn't do and vice versa. So Bob and Tom ended up doing just that. And they
00:01:49.000 ended up sitting down for a heck of a lot longer than anticipated. Both true to the sport, Bob wanted
00:01:54.160 to go down every avenue and Dom left no stone unturned. And that's why it's being divided into
00:01:59.960 two parts so that a normal human being could actually listen to it in a reasonable sitting.
00:02:05.020 Now in the first episode, Bob and Tom cover a lot of questions, both general and specific about
00:02:10.420 ketogenic diets and ketosis. They also do a bit of a deep dive on the impact of ketosis on different
00:02:16.220 forms of exercise. Now, as a reminder, Dom is an associate professor at the University of South
00:02:20.900 Florida, where he teaches at the College of Medicine and the Department of Molecular Pharmacology
00:02:25.880 and Physiology. He focuses on neuropharmacology, medical, biochemistry, physiology, neuroscience,
00:02:31.560 neuropharmacology. As a reminder, I believe Dom actually got his PhD in neurobiology. For those of
00:02:37.440 you who haven't listened to it, it might even be worth going back and listening to at least part of
00:02:42.260 the first discussion I had with Dom in 2018, because it gives you an idea of how a neuroscientist
00:02:49.400 became one of the most credible voices on ketosis, ketogenic diets, and all things ketone related.
00:02:56.880 Lastly, it is important to note that while Dom is answering specific questions and scenarios,
00:03:01.640 he is not giving medical advice. Everything in this podcast is for general informational purposes only
00:03:06.860 and does not constitute the practice of medicine, including the giving of medical advice. So without
00:03:13.700 further delay, please enjoy part one of the AMA with Dom D'Agostino. All right, welcome to a very
00:03:24.880 special AMA with Dom D'Agostino. Dom, how are you doing? I'm doing well. Thanks for having me.
00:03:30.720 Absolutely. So it's been almost two years since you were on the podcast with Peter.
00:03:36.120 I met you in New York at that time. I think it was the summer of 2018.
00:03:41.120 I know how time flies. I was just talking to my wife about that. She would ask me what I'm doing
00:03:46.420 this week. And I was like, oh, I got the podcast with Peter. And she's like, didn't you just do one?
00:03:50.500 And I mean, she was happy that it was on, but we were just amazed at how fast that time flew by.
00:03:55.540 Yeah, the time in New York. So I give you credit for dealing with New York. It's always an adventure
00:04:02.360 every time we get. Absolutely. So since then, we certainly received a bundle of questions. And
00:04:08.040 then Peter went on social media and asked if there were any questions for you and particularly what
00:04:13.140 you've been up to in the last couple of years. But maybe you could fill us in just in general,
00:04:17.460 a little bit about ketosis or how'd you get into ketosis and what you've been up to in the last
00:04:23.420 couple of years? Sure. Well, I guess, yeah, like I said, the last two years, and we are really trying
00:04:30.580 to move the laboratory science into human applications. So we've been doing quite a bit
00:04:36.040 on that front. And that has been pretty, pretty time consuming in regards to kind of setting up all
00:04:42.060 the IRB protocols. We're doing quite a bit with NASA, Extreme Environment Mission Operations
00:04:47.980 research, where I was a crew member for mission 22. And my wife was a crew member for NEMO,
00:04:55.180 the acronym they use for that for NEMO 23. And that involves looking at everything from
00:05:01.720 cognitive function, body composition, gut microbiome, sleep, heart rate variability,
00:05:09.700 stress. So we have like an IRB protocol for each one of these. And we're evaluating the effects
00:05:15.820 of hyperbaric environments, extreme environments on human physiology, and all the things that I
00:05:21.660 mentioned. And I just happen to be on a ketogenic diet for my thing. But we're trying to collect
00:05:26.600 baseline data for future missions underwater where we can have an intervention, a dietary intervention,
00:05:34.060 for example, ketosis. So that has been a big focus of our research. Another space analog mission
00:05:39.920 would be high seas. So we're preparing for that. Of course, all this stuff is being on hold now
00:05:44.340 because of COVID-19. So that's kind of outside the lab. Inside the lab, we focused a lot. My
00:05:50.760 student, now Dr. Andrew Kutnick, last week actually, he graduated. And his research, PhD research, was
00:05:58.440 focusing on cancer cachexia. And we just got his manuscript, a massive manuscript published in
00:06:05.340 iImpact Journal. And he's really happy with that. And we have some interesting findings evolving
00:06:10.920 out of that research, looking at the effects of ketones on mitigating cancer cachexia and wasting
00:06:17.560 associated with metastatic cancer in the model that actually Thomas Seyfried developed. And we're
00:06:24.240 looking at Kabuki syndrome. We're looking at various genetic diseases and developing ketone metabolic
00:06:30.980 therapies as a means to treat these diseases, not only from a metabolic perspective, but as a means to
00:06:39.000 influence epigenetic pathways that may be used to treat the disease. And the model that we're using,
00:06:46.280 for example, for Kabuki syndrome was developed at Johns Hopkins. So we were able to work with the
00:06:51.760 folks there and get access to this animal model, which we're breeding up. And like things are on hold
00:06:57.040 now, but we're doing pretty well on these experiments, getting them started up. And that's becoming another
00:07:02.680 PhD dissertation for first year student of mine, Sarah Moss. And then we have a lot of little pet
00:07:08.780 projects on the side I could talk about forever. But I think there's kind of the main ones we're
00:07:12.740 working on. Cool. Well, we're going to double click on hyperbaric oxygen, cancer cachexia, and things like
00:07:18.220 that. I know that there are some questions that came in on that. But first, there were a few general
00:07:23.480 questions for you. The first being, is there a case for one to two months of ketosis a year if I am
00:07:31.620 perfectly healthy and don't have any problems with carbs? I kind of, I don't like to use this term,
00:07:39.160 but you have to sometimes. It depends on the individual and what their goals are. But I do think
00:07:44.840 there's definitely benefits that you can derive out of, I guess, what you'd call intermittent ketosis.
00:07:50.820 The main thing is, I think one of the main benefits is that it promotes metabolic. And
00:07:57.800 so having your body, we're relative, most people are adapted to frequent carbohydrate feedings. So
00:08:04.500 their metabolism is not adapted to using fat as a major energy source during times of limited
00:08:11.980 carbohydrate availability or calorie availability. So during periods of fasting, by promoting metabolic
00:08:19.920 flexibility, and I believe when you go into a state of ketosis, whether you do it with ketogenic
00:08:25.600 diet or fasting, it changes, it actually activates a genetic program that actually can allow you to
00:08:34.480 burn fat and make ketones more efficiently. And I think once, if you do that a couple times,
00:08:39.840 we have muscle memory, workout, you take time off, it takes a little bit of time to get back to where
00:08:44.380 you left off. But you get back to that level very, very quickly. And the same thing happens with your
00:08:50.780 metabolism. I would say there's a metabolic memory associated with it. So the more you do it, the more
00:08:56.780 benefits you derive from it over time. I think there's personal development reasons for intermittent
00:09:02.700 ketosis. There's logistical reasons, too. You could be a difficult period of your life that you don't have a lot of
00:09:08.380 time just based on work or other priorities and eating ketogenic actually saves time. I know Peter
00:09:15.020 was doing something like a three-day fast every month. I think that people could implement this
00:09:21.100 idea. I think the same thing could be achieved instead of fasting. You could do six days of a
00:09:27.260 restricted ketogenic diet every month. And I think you do get the same benefits if you didn't want to just
00:09:34.700 do fasting if people have an aversion to fasting three days out of the month. The thing to target
00:09:40.780 would be the glucose ketone index. And if you're doing, for example, intermittent ketosis, this guy
00:09:47.420 has a question, and you want to derive benefits of it similar to fasting, you could restrict calories
00:09:53.500 like 50% on a ketogenic diet and do that for six days a month. And I believe you would achieve,
00:10:01.180 at least for me, a glucose ketone index between one to two. And if you do your blood work, you'll find
00:10:08.140 that you'll have almost a similar level of insulin suppression, especially if you measure that insulin
00:10:13.980 even during that week of feeding just prior to eating a meal. If you do restricted ketogenic diet
00:10:20.140 and combine that with time-restricted feeding, you're hitting all the major drivers of the benefits that you'd
00:10:27.180 get from fasting, like suppressed mTOR, suppressed insulin, your body sensing low ATP. It's probably
00:10:35.500 stimulating autophagy, although we don't have a good means to measure that. So that would be my
00:10:40.140 suggestion. If you want to, you don't have any problem with carbs, but you want to get some of the
00:10:44.700 benefits of ketosis to maybe try once a month to do five or six days or five to seven days, let's say,
00:10:54.060 of a restricted ketogenic diet, which I think it's pretty easy to do.
00:10:58.700 That makes sense. One thing that Peter was doing previously, he was doing one week fast
00:11:03.020 and he would sandwich it between two weeks. A week prior, he would go on a ketogenic diet.
00:11:10.300 And then a week after he would go on a ketogenic diet. And one thing that I noticed too, just with
00:11:14.940 my own playing around and probably other people have experienced this, is that if you're trying to
00:11:20.440 dial in that glucose ketone index, and I think, is it like directionally, you want it basically one
00:11:26.120 to one with glucose and ketones? If you can achieve that, that's pretty good. I'm a little bit more
00:11:31.580 loose on it. I think if you can achieve one to two, just based on my observations from fasting
00:11:36.940 to ketogenic diet, I think you start to derive a lot of benefits. And I quantify that through the
00:11:43.920 level of insulin suppression. I've been able to kind of record from that. So I've been measuring,
00:11:49.540 taking a lot of insulin measurements. Yeah, that makes sense. So the second question,
00:11:56.420 what are some books you'd recommend to get knowledgeable on modified keto? And I guess
00:12:00.660 the preface there is that you do a form of a modified ketogenic diet. At least last time I spoke
00:12:05.040 to you, you were doing that. Yeah, that diet has been kind of evolved over the years. But some of the
00:12:11.920 books that really influenced me that are kind of mandatory reading for people entering the lab
00:12:16.560 are Jeff Bullock and Stephen Finney's book, The Art and Science of Low Carbohydrate Performance.
00:12:22.240 That was a great book. But since then, I guess since we've last spoke, a couple of really good books
00:12:26.540 have come out. The Ketogenic Bible is a fantastic, comprehensive overview of the ketogenic diet.
00:12:35.100 And it's got everything from recipes. It breaks down the terminology. It's written for the layperson
00:12:41.440 and the people who are really interested in the science, too. Keto Answers is a great book for
00:12:47.460 the layman. And it really breaks down what a modified ketogenic diet is, recipes, suggestions on a lot of
00:12:55.000 tips, troubleshooting and things like that. Now, if you really want to geek out on the science,
00:13:00.680 I would definitely recommend, I know a lot of listeners are interested in the science,
00:13:04.640 the ketogenic diet and metabolic therapies. So Google that term, ketogenic diet and metabolic
00:13:11.660 therapies. Primary author would be Susan Massino. I am the editor of that. So kind of disclosed that I
00:13:18.260 do get royalties. It's from Oxford University Press. And it's a book that really delves into very deeply
00:13:24.680 into the science. And I guess the book that has probably one of the biggest impact on me for the
00:13:30.040 modified ketogenic diet or the modified Atkins, which sort of evolved around 2008 when I became
00:13:36.440 aware of it, was more of a clinical book by Dr. Eric Kossoff from Johns Hopkins. So if you're
00:13:43.140 interested in the modified ketogenic approach from a clinical perspective, just look up Eric Kossoff
00:13:49.320 from Johns Hopkins and check out his book on the modified ketogenic diet. Okay. So they're all the
00:13:55.880 books right now sitting next to me on my shelf. So that's the ones I'd recommend.
00:14:00.660 Yeah, I'd recommend those as well. Particularly the art and science of low carb
00:14:04.560 performances. It's not a pamphlet, but it's not a novel either.
00:14:08.180 No, it's a quick read.
00:14:09.680 Yeah.
00:14:10.160 Yep.
00:14:11.080 Update on ketone measurement devices, breath, blood, et cetera. I guess I would say urine. I'm not sure
00:14:17.080 if there are any other ways to measure, but.
00:14:20.340 That about covers it. Yeah. The urine strips are actually something I don't discourage against.
00:14:25.720 And I think they could be a good kind of yes or no if you're in ketosis and it gives you a relative
00:14:32.120 reading, but I tend not to, the Siemens multi-stick SG is pretty good and it gives you other parameters
00:14:40.120 on the urine strip. But when it comes to blood meters, which I've used most often, the precision
00:14:46.680 extra remains one of the meters I use almost on a daily basis. Abbott Lab makes that. It's
00:14:54.100 well validated. It's very reliable. It's got a track record. People publish with it. The newer device
00:15:00.400 that's out is the Keto Mojo. And I have the Keto Mojo GKI, which has the glucose ketone index sort
00:15:07.880 of incorporated into the algorithm here. And what I find is that the Keto Mojo device, it's got a lot
00:15:16.040 of pros, a lot of benefits to it. The strips are much cheaper. It does the GKI, of course. It's a
00:15:22.900 little bit larger, so it doesn't, it's a little bit bigger than the precision extra. And it records
00:15:30.600 higher beta hydroxybutyrate in the low ranges. So if I'm 0.5 on the precision extra, I'm usually like
00:15:38.060 0.9 or like a 1.1 with the Keto Mojo. Now, when my ketones get into like the 2 and 3 range,
00:15:46.480 then they're pretty, they correlate. I think the Keto Mojo may be measuring slightly higher in the
00:15:52.960 low ranges, but I also think that the precision extra may be measuring slightly lower. And there
00:15:59.900 is, for example, if I was 0.8 from an assay we do in the lab, I think the Keto Mojo would maybe have
00:16:08.020 me at 1.0, whereas the precision extra would be 0.5. So I think there's somewhere in the middle
00:16:13.720 is the correct one, but they're relatively, they're easy to use. And I think they're devices
00:16:19.240 that I use pretty much on a daily basis. The breath acetone meter, now that's what I've been
00:16:24.480 spending a lot of time evaluating that technology. Biosense makes this device. And in regards to
00:16:31.580 breath acetone meters, I would say it's like a next level kind of stuff. The breath acetone
00:16:37.360 does correlate well with beta hydroxybutyrate from my measurements if you're in a fasted state.
00:16:43.480 So it's exceptionally good in a fasted state. There are some drawbacks to it, I think. For example,
00:16:50.860 if I have wine or if you eat a meal, you're going to get a false positive, which means you're going
00:16:56.560 to get an elevation breath ketones that's outside of the spectrum where you're really at. And that
00:17:02.700 suggests that it's picking up something other than breath acetone. Definitely picks up breath alcohol,
00:17:08.500 but it is pretty reliable. I've used it hundreds of times, and that would have been thousands of
00:17:13.980 dollars worth of strips. And it correlates well, especially if you're into fasting. And if you're
00:17:19.700 following a ketogenic diet and you just abstain from food or chewing gum or alcohol or whatever for
00:17:25.780 a good hour, then the measurements correlate pretty well with beta hydroxybutyrate in the blood.
00:17:34.200 A couple of years ago, I had a, what was it called, ketonics, which I think was measuring
00:17:39.140 acetone. And it wasn't, what should I say, quantitative. It basically gave you a, I think
00:17:44.420 it was a green, a yellow, or a red. And I think green meant that you're probably not in ketosis. And
00:17:50.400 then yellow was moderate. And then red was something along the lines of deep ketosis. I don't know if
00:17:54.900 this correlates with maybe the urine strips or something like that. Is the one that you have,
00:17:59.180 is it, is there something that you can quantify in terms of the amount of acetone?
00:18:04.000 Yes, they have ACEs and 10 ACEs. You might see some of the measurements I've been posting,
00:18:11.360 like on Instagram, 10 ACEs would correlate to 1.0 beta hydroxybutyrate pretty much. So it's like
00:18:18.840 an order of magnitude above. And I think I got that right, but you might want to check out the specs.
00:18:24.900 On the website. So yeah, it's just in order of magnitude higher, the numbers. And these numbers
00:18:33.840 were developed to sort of correlate to beta hydroxybutyrate. I think that's how it's more
00:18:40.320 or less calibrated, sort of in that way, the algorithm. And they've done quite a bit of work
00:18:45.280 at bioscience to make the meter reliable, which I, on my third one now, I have to say,
00:18:50.560 because the first two, I think were sort of beta versions. Just sent the other one back and I have
00:18:56.720 a new one now, but I carry it with me in my pocket. It's been to many countries. It worked well and it's
00:19:04.140 reliable. So the ketonics meter, I think has gradually become more quantitative. So you might
00:19:10.420 want to check to see the latest version of that. Although I have to say that the biosense breath
00:19:15.920 acetone meter is the most quantitative breath meter that I've seen so far. And they've done quite a bit
00:19:22.640 of research. One other drawback is that it takes about a minute or two to calibrate. So you have to
00:19:28.940 press it and kind of wait to blow in it. If you're kind of impatient, you could probably take a blood
00:19:34.200 measurement a little bit quicker. And if it's windy out or you're outside, things sometimes get an error
00:19:40.960 reading. But generally, I'm testing at my desk, I'm testing inside. And, you know, I do like
00:19:47.480 measuring blood, but this is a very close second to my favorite measuring device if I'm going to
00:19:52.700 quantify ketosis. Breath acetone is a very strong indicator of fat oxidation. So if you're just using
00:19:59.380 it as you're following a ketogenic diet, burning fat, that acetone is basically was derived from fat.
00:20:05.820 So you have it's a very good quantitative measurement of fat oxidation. Also, from the
00:20:10.960 clinical perspective, which I'm most excited about is that a lot of kids do not like to get their
00:20:16.080 finger pricked, obviously. A device like this is very appealing to children who have epilepsy and breath
00:20:22.120 acetone correlates really well with seizure control. So I'm excited that this technology can make it into
00:20:28.300 the clinical realm, especially in epilepsy. Yeah, I was going to ask you actually between beta
00:20:34.520 hydroxybutyrate, acetoacetate and acetone, if it's actually telling you something a little bit
00:20:39.760 different physiologically or biochemically, that maybe one may tell you a little bit more about
00:20:43.780 the availability versus utilization. And it sounds like with the acetone, it might actually tell you
00:20:49.320 a little bit more about the ketones that you're actually burning. And I think you mentioned this,
00:20:53.280 that instead of a glucose tolerance test, you thought of like a ketone tolerance test. When you think
00:20:58.220 about it, if you're utilizing the ketones quite efficiently, then, and this is one of those things that I
00:21:03.700 think, some people get into ketosis, meaning they get into the diet or ketogenic diets. And it's
00:21:09.180 almost like a challenge to see how high you can get your BHB, like how high are your ketones.
00:21:14.140 But in some ways you think, well, maybe I want to utilize those things. And if I'm utilizing them,
00:21:18.580 then maybe it would be the substrate might be small, lower for BHB. But it sounds like that's right,
00:21:23.460 that the acetone tells you a little bit more about the utilization of ketones versus maybe BHB.
00:21:27.860 Yeah, you bring up a good point. I think if beta-hydroxybutyrate stays circulating in the
00:21:33.060 blood longer, it's more likely to, you're going to have more acetone as well. And that can
00:21:39.640 spontaneously decarboxylate or acetoacetate, I should say. And you maintain a ratio of about
00:21:45.000 four to one. And some measurements I've seen people at six to one beta-hydroxybutyrate to
00:21:49.660 acetoacetate. So if your acetoacetate is elevated in the blood, that spontaneously decarboxylates to
00:21:55.740 acetone. And that's what, it's very volatile. So you're breathing that off. But in regards to the
00:22:00.460 ketone tolerance test, yeah, if you're using ketones at a fast rate, there'll be less beta-hydroxybutyrate
00:22:05.760 and acetoacetate available for spontaneous decarboxylation. So that volatile organic
00:22:12.560 compound is not going to show up in the breath. So if you exercise, acetone goes down. I did yesterday
00:22:17.980 and noticed that a workout can really lower my acetone level, breath ketone, as it does with
00:22:24.880 blood beta-hydroxybutyrate. But if I work my metabolism up and I come back to my desk and I'm
00:22:31.000 sitting there and you have like that post-exercise elevation and metabolism, then you start seeing
00:22:36.160 that acetone starting to shoot back up again when you're at rest. Because the ketones are, you've
00:22:41.720 ramped up metabolism, fat oxidation, ketogenesis, and you start building up ketones, but you're not using
00:22:47.680 them. And athletes do really well, I guess you could say, on a ketone tolerance test. Because if you
00:22:53.880 give them a bolus of exogenous ketones, they clear it from the system pretty quick. And they clear it
00:23:00.320 very quick when they start exercising. So which is a really good indication that they're using
00:23:04.780 that metabolic substrate for fuel. You talked about this a lot. George Cahill,
00:23:10.340 his study, the 40 days of fasting, and he looked at, what did he look at? He looked at beta-hydroxybutyrate.
00:23:15.320 And I think on the same graph, he had acetoacetate and free fatty acids. I don't think that he had
00:23:20.080 acetone. But maybe a future question, I don't know if it's in here, but something about free
00:23:24.880 fatty acids and acetoacetate seem pretty close, that they were pretty close together as far as
00:23:30.360 substrates, but gets into the idea of how many free fatty acids are we burning compared to maybe
00:23:35.440 ketones as well, and the interplay between those two.
00:23:38.460 Yeah, there's some interesting dynamics going on for sure. And I think you'll notice a couple things
00:23:43.820 from that work. You'll notice that, well, they didn't measure acetone because it's very hard to measure.
00:23:47.540 We've just doing the experimental procedure to store the blood to make an acetone measurement
00:23:55.100 possible through gas chromatography and mass spec. It's quite an achievement. So it's kind of hard to
00:24:01.200 do because it's volatile. But you'll see that glucose was relatively stable throughout. Another
00:24:06.580 diagram on the same subjects demonstrates an injection of insulin or IV infusion of 20 IUs of insulin.
00:24:13.920 You see fatty acids in the blood go down, ketones go sharply down. So you see a lot of that ketogenesis
00:24:21.920 and fat mobilization for fuel is really a function of insulin suppression. I think that's really
00:24:28.820 important to note. And that has implications for sort of other things, like do exogenous ketones
00:24:34.200 elevate insulin? And so if you take exogenous ketones, will it promote a decrease in your own endogenous
00:24:41.040 ketone production? And I think it's really important to understand what's going on in the liver and what's
00:24:47.020 going on in the muscle and what's going on in the brain when you're delivering exogenous ketones,
00:24:52.000 which we think have many therapeutic applications and everyday applications. So that's, I've been
00:24:57.700 focusing a lot sort of on some personal studies on that now and also in the lab. We're looking at that.
00:25:03.800 So let's get into, we've got a couple of questions around genes. The first one is very broad. It says,
00:25:10.340 what genes are not good for keto? They're EG, for example, FTO. I'm wondering if this is around
00:25:16.980 maybe like the PPARs and FTO. And I think some people have talked about this and how they handle
00:25:24.100 saturated fat and fats in the diet and things like that. Are you aware of any of this literature?
