Snacking just makes me hungry. I think I put on 2-3 pounds on the weekend just because food is much more readily available at home than at work. When I was in my early 20s, I would eat a pound bag of Doritos on a long car drive and still still feel hungry at the end.
I've also found that some of the "hunger" pangs I feel aren't really hunger. It's more of "it's time to eat!" pang than a "my stomach hurts because I haven't eaten in 3 days" pang. Habits based on the clock are hard to break... I used to occasionally not eat for a day just to remind myself of what real, as opposed to fake, hunger felt like. But I haven't done that in a while.
But people are different. If you find something that works for you, stick with it.
Best of luck with the diet!
Cheers,
Scott.
