In today's AMA, we discuss how to build and analyze a meaningful family health history, how risk tolerance changes decisions around testing and treatment, why heart disease remains so poorly prevented despite the tools we already have, whether someone can carry excess body fat and still remain metabolically healthy, the minimum effective dose for strength training for people who don't have a lot of time, and the habits and interventions that may matter most for reducing dementia risk.

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.
