The Brain-Healing Foods That Prevent Cognitive Decline

Brain changes do not happen overnight. Memory issues, mood changes, and poor sleep often build slowly over decades, driven by inflammation and metabolic stress. In this video, Dr. David Jockers explains why daily habits around eating, movement, and sleep play such a big role in long term brain health.

He walks through why intermittent fasting is one of the simplest strategies to support brain function, starting with stabilizing blood sugar and lowering insulin. You will hear how fasting shifts the brain toward using ketones for fuel, and how that relates to inflammation, oxidative stress, and communication between brain cells. Dr. Jockers also explains the importance of preparing the body with enough protein, healthy fats, and colorful fruits and vegetables, along with why olive oil, movement, and sleep support these processes. The goal of this conversation is understanding how food timing, metabolic health, and lifestyle patterns work together to support focus, calm, and cognitive resilience over time.
