But to the extent that you can eliminate stress, you will eliminate the composition or deposition of visceral fat inside of people. So it's really an important discussion for people to be aware of. And then the final point that we see is, believe it or not, and it came as a surprise, is durational exercise, where we simply exercise too much.

And so we see that people that are runners, and I'll pull up a nice scan of this. Here's an MRI of somebody who's a marathoner who had run eight to 10 marathons. a year, he had a lot of this visceral fat within him. And he had this very small amount of subcutaneous fat. So we call these people with low subcutaneous fat on the outside, TOFIs. So they're thin outside, and fat inside.

So this marathoner was filled with a lot of visceral fat. So we see, and it's probably two things. One, it contributes to visceral fat when you overexercise and the exact mechanism is not clear. But my theory is it's probably through elevated reactive oxygen species, ROSs that go around that are associated with exercise. If you exercise too long and too much,

But my theory is it's probably through elevated reactive oxygen species, ROSs that go around that are associated with exercise. If you exercise too long and too much,

you enhance these ROSs from being produced. And so another example of this happening is a really nice before and after scan in a 58-year-old executive of a company who came in and he was having his repeat abdominal scan, his MRI.

Yeah, so on the left side is an MRI scan. image of his abdomen and he's got a substantial amount of visceral fat within his abdomen. His muscles look pretty good and he was a pretty healthy guy. He was doing a lot of healthy things, 58-year-old executive. And this was a repeat itself. I don't have the MRI before it, but it was disappointing and alarming.

So we asked him all the other contributions of visceral fat and he assured us and we were reassured by his answers that he didn't have any of those other contributions. And here he disclosed to us that he was persisting in his running. He wasn't doing marathons, he was doing 10 mile runs five days a week. So 50 miles a week, which is a lot of running.

As a consequence of all the running, he had a substantial amount of visceral fat that was staying there. And what visceral fat distance running appears to do is makes the elimination of visceral fat refractory. So not only does it seem to contribute to visceral fat, but when you start doing things like cutting out processed foods and sleeping better, cutting out alcohol, and then you get
