I found eating at 2pm and 8pm worked for me. In the morning, if you don't eat, your digestive system seems to remain inactive so you're not that hungry until 2pm. By eating at 8pm you're eating late enough that you'll be asleep before you get hungry and want to snack. This gave me 18 hours of fasting, 12 hours digesting the last meal and about 6 hours of my body burning my fat stores for energy.

I combined this with reduced carbs so when I did eat, it was a longer time before I felt hungry because reduced carbs means not getting the sugar rush and then the crash a couple of hours later where you feel very hungry.
