Yeah start with the 12 and work your way up to the 16! You will see some major health benefits from it! Let me know how it goes! Thanks for the comment!
I have always heard of this but never seen details. Very informative! My schedule now only allows me 9-10PM workout followed by a protein shake and some crackers to get the protein taste to go away. I’ll try the 12 hour and see if I can get a 30 minute run in during the morning.
