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.

Welcome to the Dr. Berg's Healthy Kito and Interminute fasting podcast, where Dr. Berg takes you on the journey for the truth about getting healthy and losing healthy weight. Hey guys I want to tell you what happened when I increase my fasting to 21 hours. It's quite interesting. I did an experiment on myself. Now normally I eat around 12 or maybe 1 and 6 and 7 so I get about 18 hours of fasting with a six hour eating window and

three so the experiment that I did in myself is simply eat when I got back from filming.

So my first meal was at three and the second meal was at six.

2:11.0

Okay, seven, increase productivity, I mentioned that already, I'm just getting a lot more done, more organized because of the focus and more decisive. So I really don't need any study to convince me. All I needed to do was do

2:26.4
