Hey everyone, welcome to a sneak peek, Ask Me Anything, or AMA episode of The Drive Podcast.

I'm your host, Peter Attia.

At the end of this short episode, I'll explain how you can access the AMA episodes in full, along with a ton of other membership benefits we've created.

Or you can learn more now by going to peterattiamd.com forward slash subscribe.

So without further delay, here's today's sneak peek of the Ask Me Anything episode.

Welcome to Ask Me Anything AMA episode number 77.

In today's AMA, we break down the science of dietary fiber.

Moving past the sort of generic advice to eat more fiber, to understand what it actually does to the body, where it's truly beneficial to health, how to use it effectively, and

and where its reputation may exceed the evidence.

In this episode, we will discuss how different types of fiber, soluble, insoluble, viscous, and fermentable work in the body and how their distinct properties result in different functional outcomes, whether fiber meaningfully impacts satiety, weight management, and glycemic control, and how those effects compare with more potent tools, how certain fibers influence lipid metabolism and cardiovascular risk, and whether their magnitude of effect justify their reputation,

what the mechanistic and epidemiologic evidence really say about fiber's role in colorectal cancer prevention, including the potential influence of short-chain fatty acids like butyrate, who might not tolerate certain fibers well and how to tailor their intake accordingly, how to move beyond the simplistic goal of getting enough fiber towards a more strategic approach that maximizes its actual benefits,

Now, if you're a subscriber and you want to watch the full video of this podcast, you can find it on the show notes page.

So without further delay, I hope you enjoy AMA number 77.

It really comes down to the importance of occasionally checking things that we view as axiomatic or dogma.

So the general consensus is that fiber is good, the more you eat the better, end of story, case closed.

But if we're going to be critical of our beliefs, we have to acknowledge that the recommended daily allowance for fiber is almost entirely based on epidemiologic studies.

And we know that epidemiologic studies have left us on the wrong track with many of their recommendations.
