I've watched a lot of Dr Ekberg's videos.  He does an excellent job of explaining how things work, and what works and doesn't work.  This one is just as good as the rest.  I like how he compared different fasts in his other videos.  I eat 2 meals a day now.  I have only ate breakfast and handful a times this year.  It doesn't make any difference if I eat it or not, I still get a hunger pain around 10:30, and it always seemed worse when I ate breakfast.  Longest fast for me would have been about a 24 hour when I tried Omad for a couple days.
