Honestly, not to go against the grain, but I advocate eating however many meals you can comfortably fit into your daily regimen. If that means 3-4, so be it. If that means 5-6, great.
Assuming cals and macros are accounted for, in my experience there really isn't going to be much of a net difference, if any at all, once said and done.
Just as some are more satiated on more meals, I've met a good number more satiated on fewer meals. Go by what feels right for you and your personal preferences/schedule.
I can tell you that I've gotten just as lean (leaner actually) eating 3 meals as I did 6.
Here's an interesting article by a guy I thoroughly respect with some info. Some of the research used is shotty at best.... but it's what we've got to work with for the time being unfortunately.
