What can you tell me about this?

**Andrew Koutnik** (0:31)
Well, if you look at the science, it's enhancing cognition. We've seen a 15% improvement in how individuals were able to read and absorb information of better decision making. And also we did a study and showed that it delayed the progression of metastatic cancer. And I've actually taken this a number of times because having been in research for the last 15 years and having lived with multiple chronic diseases, one of which I reversed some of the most powerful strategies like this or not being told to me when I went to the doctor's office. So let's dig deeper.

**SPEAKER_3** (1:01)
Dr. Andrew Koutnik is a research scientist who's worked on over 100 studies on metabolic health, diabetes and the keto diet.

**SPEAKER_5** (1:09)
And through his findings, he's helping people prevent chronic diseases, improve cognition and optimize performance.

**Andrew Koutnik** (1:15)
I went through some pretty dramatic moments in my childhood. You know, I did everything I was told, right? I exercised all the time. I ate what I was supposed to eat, but I still became obese.

**Steven Bartlett** (1:24)
You weighed about 255 pounds? Yep.

**Andrew Koutnik** (1:27)
And I had no idea how damaging that actually was to my body. And I think the vast majority of people also don't. But over 20% of children have obesity. That's quadrupled over the last 30 years. And a big part of that is when it comes to food, what looks healthy isn't always healthy. And it's not by accident. And it wasn't soon after that I ended up getting diagnosed with a chronic irreversible disease that obesity puts you at risk for. And that immediately turned into a journey to understand how to be healthy. And I came across this diet a little over a decade ago called the ketogenic diet. So then I went into the science of this diet and found positive impacts on things like diabetes, obesity, Alzheimer's, serious mental illness, chronic diseases. And I was like, oh, wow, because a lot of people don't realize that many of these are not just preventable but also reversible.

**Steven Bartlett** (2:13)
And you did the longest study ever done of its type on the impact of the ketogenic diet on a patient that had type 1 diabetes.

**Andrew Koutnik** (2:20)
Yes. Let me tell you all about it.

**Steven Bartlett** (2:24)

**SPEAKER_1** (3:03)
Thank you.

**Steven Bartlett** (3:08)
Dr. Andrew Koutnik, if you had to try and sort of summarize and encapsulate what you spent the last couple of decades of your life focused on and really trying to accomplish, prove, understand from the highest level, what exactly is that?

**Andrew Koutnik** (3:23)
The core of my mission, Steven, is really to empower individuals to take control of their own health. It's empowering them with science, you know, bridging science to actual action. And, you know, science is very complex. It's very hard to break it down. But having been in research for the last 15 years and having lived with multiple chronic diseases, one of which I reversed and one of which is irreversible, my mission is to empower patients with the same tools and strategies that I had access to so they can take control to maximize their health and performance.
