| 0:00.0 | My name is Ben Greenfield, and on this episode of the Boundless Life podcast. |
| 0:05.0 | And we ran these studies. And what we saw is that there was no difference. Once the athletes |
| 0:10.7 | adapted for four weeks on the ketogenic diet between a high carb diet and a very low carbohydrate |
| 0:16.5 | ketogenic diet. But here was the kicker Ben. Welcome to the boundless life with me, |
| 0:22.8 | your host, Ben Greenfield. I'm a personal trainer, exercise physiologist, and nutritionists, |
| 0:27.9 | and I'm passionate about helping you discover unparalleled levels of health, fitness, longevity, |
| 0:34.1 | and beyond. |
| 0:41.0 | Let's talk about your noggin, about your brain health. |
| 0:45.1 | I know a lot of you struggle with it. |
| 0:46.6 | I do sometimes, especially when I'm traveling, and brain fog or mental fatigue, |
| 0:51.2 | even after a good night's sleep is something that happens. We're talking forgetting |

Plus, when oxidative stress starts dampening and damaging your neurons. So over time, that weakens what's called synaptic plasticity. That's the foundation of memory and focus and learning. |
| 1:29.1 | So what level up health, one of my favorite companies that creates these amazing clinically |
| 1:32.8 | backed peptide and botanical formulations that you take orally has done is they've created |
| 1:37.7 | a process to boost BDNF, grow new neural connections, sprout them like miracle grow, and protect against cognitive decline. |
| 1:46.2 | They have stuff in there to enhance blood flow to strengthen memory, to improve learning, |
