Intermittent fasting can protect the brain against epileptic seizures and reduce IGF-1 levels.

“And we found that the most striking effect was in the model of epileptic seizures where we administer what's called an excitotoxin. It's a very interesting story. It's a naturally occurring chemical that's produced in algae. And it accumulates very high levels during red tide seasons where it's dry. And so, there was these incidents, an incident in Canada where these people who had eaten shellfish at a restaurant develop memory loss, amnesia. And it turns out that the scientists trace this back first to the shellfish. They'd all eaten the shellfish. And then, the shellfish had high levels of this excitotoxin, it's called domoic acid. And they had high levels because they are eating the algae that had high levels. So, as you go up the food chain, toxins accumulate. Anyway, to make a long story short, the intermittent fasting protected against epileptic seizures and protected the neurons from being excited to death.”
