High blood sugar doesn’t just affect your body—it may also quietly shape brain health, memory, and energy.

In this episode, I speak with Dr. John Lewis about the surprising ways chronically elevated blood sugar may impact the brain, including the science behind “caramelizing the brain,” neuroplasticity, brain fog, and the afternoon crash.

Together, we explore the connections between diabetes, sleep, inflammation, and dementia, along with practical nutrition ideas and a broader conversation about how everyday choices can support long-term brain health.
