How do you all endure hunger while on a diet?

I'm trying to manage on just one meal a day, but

My stomach would rumble every night, haha.

Even if you fill it with water, there is a limit.

I feel guilty again when I say I'll just have a little snack...

What was the best option for you in situations like this? Please let me know in numbers.
