I've been doing this since Jan 1, sometimes called OMAD for One Meal A Day. I had already been skipping breakfast, so lunch is now a cup of tea or diet soda. Maybe it's just the excitement of a new diet plan, but it's helped me lose 25 pounds so far this year, on track for 35 total before I re-evaluate. I just don't seem to have the willpower to only snack in moderation, but limiting myself to an hour a day is working. I can still have that dessert I'm looking forward to, it just has a specific timeframe now. Do I feel hungry sometimes? Yes, but I need some practice being hungry after years of stuffing my face whenever I felt like it.
