I'm the same as you (one or two meals a day) but I don't think we can generalize our experiences to a recommendation (especially across gender lines).

My partner gets impossible really quickly if she doesn't eat about four times daily, and I've met enough hangry-type people to believe that some people really do have to snack. Although I guess I'd encourage everyone to try not-snacking given how much more convenient and healthy it is if your metabolism can manage it.
