00:00:00.000 Hey everyone, welcome to a sneak peek, ask me anything or AMA episode of the drive podcast.
00:00:15.820 I'm your host, Peter Atiyah. At the end of this short episode, I'll explain how you can access
00:00:20.280 the AMA episodes in full, along with a ton of other membership benefits we've created,
00:00:24.900 Or you can learn more now by going to peteratiyahmd.com forward slash subscribe.
00:00:30.600 So without further delay, here's today's sneak peek of the Ask Me Anything episode.
00:00:38.860 Welcome to Ask Me Anything AMA episode 84.
00:00:42.820 In today's AMA, I answer listener questions across a wide range of topics.
00:00:47.640 Less about deep dives and more about how I think through real world trade-offs and apply
00:00:52.400 the science and practice.
00:00:53.500 In today's episode, we're going to discuss how to build and analyze a meaningful family health
00:00:59.920 history, how risk tolerance changes decisions around testing and treatment, why heart disease
00:01:05.520 remains so poorly prevented despite the tools we already have, whether someone can carry excess
00:01:11.240 body fat and still remain metabolically healthy, the minimum effective dose for strength training
00:01:16.460 for people who don't have a lot of time, the habits and interventions that may matter most
00:01:21.520 for reducing dementia risk? What would need to change for me to reconsider my point of view
00:01:26.540 on the supplements that boost NAD, such as NR and NMN, and when hydration and electrolytes matter,
00:01:34.020 and when they're mostly overkill? So without further delay, I hope you enjoy AMA number 84.
00:01:40.560 board. Peter, welcome to another AMA. Today's AMA is going to be another mixed bag of topics
00:01:53.340 covering a variety of things. Again, these aren't meant to be deep dives on the science. The focus
00:01:59.300 is more how you talk with patients, how you think about decisions, how you weigh trade-offs for
00:02:05.100 yourself and for others. And so we'll move across a variety of topics. This will include conversations
00:02:11.420 around family history, what it is, when it's more useful than genetic testing, how you use it with
00:02:17.360 patients and how people should think about it, how you think about various people's different
00:02:22.400 feelings around taking risks as it relates to their health and how that affects their decision,
00:02:27.680 look at cardiovascular disease prevention, ideas around can someone be metabolically healthy while
00:02:33.200 still being overweight and what that looks like. We'll talk about strength training, what is the
00:02:39.240 potential minimum effective dose, and how do you prioritize different exercises for people who are
00:02:44.860 busy, which is the vast majority of people listening to this. We'll also look around
00:02:50.100 dementia risk, any updated thoughts on NAD boosters such as NMN, NR, hydration, electrolytes,
00:02:58.220 and more. So all that said I think we'll get into it with talking about family history. So we've
00:03:08.440 talked about family history before as something that you find very insightful and sometimes if
00:03:15.460 not often even more insightful than genetic tests. So before we get into the best way for someone to
00:03:22.340 collect and analyze their family history. Do you want to just kind of talk about why you think
00:03:28.460 family history is such a valuable and often underutilized tool that people have?
00:03:34.700 Well, there's no doubt that genetics play a role in disease, but the truth of the matter is that
00:03:42.200 most conditions arise from a polygenic backdrop, right? So it's easy to think about the examples of,
00:03:49.300 you know, a single gene gone awry leading to a disease. But the reality of it is that's the
00:03:55.700 exception and not the rule. So when someone says, you know, heart disease runs in my family or
00:04:00.880 cancer runs in my family, it's usually not going to be tied to a single gene. And even if you do
00:04:08.080 genetic testing, you're unlikely to see exactly what's causing it. So instead, what we want to do
00:04:16.420 is look at the family history, because the other thing that's a little confusing about genes is
00:04:23.760 they don't always reach what's called the same degree of penetration. So again, in extreme cases,
00:04:30.820 we know that there's complete penetration of a gene. So if you have the gene, you have the
00:04:34.500 condition. But again, it becomes much more nuanced when you start to think about the big ticket items
00:04:40.400 like diabetes, heart disease, and cancer. So that's really the reason that we think that there's
00:04:46.660 actually more fruit to be had in doing a very thorough assessment of a family history when the
00:04:53.120 data are available. Obviously, there are going to be situations where that's not the case,
00:04:56.880 if a person's adopted or estranged from their family. But in our experience, most people have
00:05:02.100 access to enough information that we can start to hone in on risks. And then, of course, that
00:05:07.640 doesn't mean we're opposed to using genetic testing as a way to sharpen that lens. Again,
00:05:12.520 I think that there are certain cancer panels, cancer genetic panels, that is, that can add a
00:05:17.300 little bit more light around certain types of cancer, such as breast cancer. But, you know,
00:05:21.980 I just think that the more information you can have here, the better. And so for someone listening,
00:05:28.220 what is the best way for them to not only gather their family history, but then also start to
00:05:36.360 analyze it and understand where they should be more thoughtful in the future around their health.
