Four Factors That Support Muscle Mass

All right. Chris says, hi, Rhonda. In an interview a long time ago with Joe Rogan, you mentioned 2 supplements that counteract muscle atrophy, ursolic acid and tomatidine, that they were looking promising. Has there been any more research on their usefulness in preserving muscle in older adults? I will say this. The most important players for muscle mass are protein intake, at least 1.6 grams per kilogram body weight. Resistance training, anything you can do, bodyweight exercise, that, that anything. Then after that would be omega-3. So you want to have more of the higher, higher, you know, you're going to get to the 2 to 4 gram triglyceride form range. And heat from either a sauna or hot tub.

So both omega-3 and heat work on basically preventing disuse atrophy, which is a pretty big problem in older adults. So, like, when you're not physically active, you know, when you're not doing resistance training, you know, atrophy, sarcopenia, these things, you're battling these things. And so omega-3 seems to sensitize your muscle to amino acids that are anabolic, like leucine. And so it kind of almost seems to help make a lower dose of protein more effective. In other words, you're getting more bang for your buck with the same dose of protein. That's the working hypothesis, at least from Dr. Chris McGlory. You know, more work to really confirm that, but it's the working hypothesis right now. Heat from the sauna, there's now been a couple of studies on that.

Those studies really seem to suggest that heat is preserving and preventing muscle atrophy, and possibly even in combination with resistance training, more anabolic than resistance training itself, by itself. So, you know, more work needs to be done on that. But I would say I would focus on those things. Those are the major players.
