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.
