I want to tell you what happened when I increased my fasting to 21 hours. 

Normally I eat around 12-1 and 6-7. I get about 18 hours of fasting with a six-hour eating window. For my intermittent fasting experiment, I had my first meal at 3 and my last meal at 6. That's just a three-hour eating window, which gives me 21 hours of fasting. This may not seem like much, but it made a significant difference in my cognitive function. 

 The intermittent fasting benefits I experienced after 21 hours:
 • Improved memory
 • More focus
 • Better learning
 • Better at locating things
 • More creativity
 • Better mood
 • Increased productivity
 • More organized 
 • More decisive 

Here's what happens. You increase something called BDNF. This is a protein that helps you grow neurons and slow aging.

More health benefits of intermittent fasting:
 • Increases ketones
 • Increases autophagy
 • Improves synapses 

You may already be doing this intermittent fasting pattern, or you may be doing OMAD (one meal a day). But, if you're at 18 hours or less, I challenge you to start trying 21 hours of fasting. Try it for three days, and then evaluate your cognitive function.
