Peter, is this graph accurate, roughly? Yes, this would be accurate.
It's preventing decline. Most of us reach our peak bone mass in our 20s. So the name of the game is prevent it from getting any weaker. The good news is, by the way, I had a woman on my podcast named Belinda Beck who studies osteoporosis. She's from Australia.
And she did this amazing study there called the Lift More Study where she enrolled a bunch of women with osteoporosis who had never done any resistance training. And half of them were randomized to the usual activities like yoga and things of that nature. And then half of them were randomized to heavy resistance training.
And the women that did the heavy resistance training actually, first of all, on DEXA saw no change in bone density or saw a very minor reduction in bone density compared to a significant reduction in the women who were not resistance training. But more importantly, on CT scans,
The women who had done the resistance training actually showed an increase in cortical thickening of bone, suggesting that it might even be that DEXA is not by itself sufficient to fully assess bone health. It assesses bone density, but not necessarily bone health. And her hypothesis is that these women might actually be getting stronger bones, even if the density is going down just a little.
But either way, even if density were sufficient, the fact that their density went down so much less than the others was amazing. And it's actually, you know, if you can find the video and link to it on YouTube, Belinda Beck's Lift More study. It's just an awesome video to watch these little old ladies walking around picking up, you know, dead lifting their body weight and stuff like that.
Yeah, calcium, vitamin D, protein. Everything that's going to support muscle mass as well because that's the other thing that we found here. So we looked at your body fat percentage. Again, in absolute terms, not that high, but for your age, pretty high. Because you're young, so you're at the 80th percentile for your age. And your visceral fat was at the 50th percentile for your age.
So we don't really care that much about total body fat. We care a lot more about visceral fat. So the fact that your visceral fat was at the 50th percentile, visceral fat is the fat that's around your organs. That's the more metabolically deranging, damaging fat. We actually have a very high standard. We want to see that below the 10th percentile. Thank you. Thank you. Thank you. Thank you.
Thank you.
Thank you.

Thank you. Thank you. Thank you. Thank you. Thank you. Thank you. in an otherwise healthy environment, right?
So if you talk about the individual who comes home and has a glass of wine while he's with his wife and they kind of unwind in the backyard and talk about their day and things like that, there might be benefits from doing that that outweigh the very, very small amount of toxicity that came in that ethanol.
Once you reach about 30 grams of ethanol a day, I don't see, and I have not seen, a shred of evidence that there is any amount of pro-social behavior that can offset the toxicity of that ethanol. So while I would not go as far as the World Health Organization, which has condemned ethanol as a carcinogen at every dose, I just don't see the data to make that case for every dose.
I tell my patients in a very measured, nuanced way, kind of what I just told you. Like, you know, I drink alcohol, but I think about it every time I do. Like, is it worth it? Is it worth it? Is it worth it? Like, I'm not just drinking for the sake of drinking. I have this expression, don't drink on airplanes because the alcohol sucks. Like, I'm not just drinking to numb myself, right?
Like, if I'm going to drink, there's a reason. It's going to be really freaking good. And that, for me, amounts to probably like four drinks a week.
Well, first of all, as a disclosure, I'm an investor in a company that sells electrolytes, so LMNT. So I'm an investor in that company, which I always want to disclose stuff like that if it's pertinent. The short answer is it depends. So why did I get interested in electrolytes? Well, I historically never consumed electrolytes when exercising.
I was pretty much always consuming water and or water plus carbohydrate, depending on the intensity and duration of the exercise. I also tend to have very low blood pressure. And a couple of years ago, I had a really, really bad fall when I woke up in the morning and I was jet lagged. So I had just flown to Brazil. So obviously you get a little bit dehydrated on a plane.
And then the first, like, you know, you get in whatever that night. And then the next morning I woke up, got out of bed and face planted into a table. You can probably still see the scar on my forehead. And I get back home and, you know, my doc measures my blood pressure. It's like 95 over 60. And he's like, yeah, you're just you're really dehydrated, man. Like we need to get a little more.
