As others have said, any fasting period is a benefit, longer fasted states offer more benefit than shorter ones but basically, any time you are not eating is a good thing. So stick to mealtimes and try not to snack. But it should not be a difficult thing - as you body adapts and you learn to listen to it and not just slavishly follow those previously-habitual eating patterns, it all becomes easy and natural.
I never eat more than two meals a day, but personally I like to eat quite late in the evening, around 9pm, so my fasting is split into two periods - say 10pm to 12:30, and 13:00 to 21:00. One longer fast would be better but is doesn’t always suit me. I also try to go 2 or 3 days a week just eating dinner, but I do this as and when it feels right and don’t plan it. Yesterday I was pleasantly hungry at 11:30 so I had some lunch. The day before I had a 24hr fast. Both felt fine.
It’s very liberating to be able to eat as and when you are hungry, as much or as little is required to reach satiety. But do ensure you are eating enough and of the right stuff to not suffer cravings or inappropriate hunger.
