I used to do 16/8 or 18/6 and it's pretty easy. I still usually don't eat breakfast because it makes it easy to get > 12 hours fasted. A few months ago, though, I started doing a 24 hour fast every week. It takes some planning but it's surprisingly easy. I'm damn hungry by the end, but it's never been an issue. I'll even work out and lift heavy 22+ hours into the fast without a noticeable decline in strength. I have no plan to stop doing this.
