How long do I need to fast to spike brainpower?

To start seeing these incredible cognitive benefits, you have to fast for at least 18 hours a day.

With an 18:6 intermittent fasting pattern, you would fast for 18 hours and have a 6-hour eating window. This means no snacking while fasting. You can eat during your 6-hour window, but I recommend only two meals. If you are still hungry, add more fat at the end of your meals.

Ketones are very therapeutic for your brain.

There are three ways to get your body to produce ketones:

1. Go on the keto diet

2. Fasting

3. Exercise
