Science Behind IF and Keto

Scientific Studies For Your Pleasure

If you are anything like me, you love to get the actual source of things. I found early on that love reading the actual data and do not really trust most peoples interpretation of it, simply because these days they have their own agenda which is usually trying to sell you something. :) 

So when I can, I will post the sources that I use here.  I will always make sure I make this free and anyone can come here. 

For now, it is going to be just an info dump. One of these days I may cataloged.  In the meantime, have fun and hope this helps.  

If you have reliable information source, please feel to let me know in the comments below and I will do my best to add it here based on the accuracy of the source.

This portion below is on the impact of insulin and is borrowed from Ivor Cummings.
