I'm pretty sure eating 5-6 small meals boosting your metabolism is a myth. It's amazing for your psychological well being though. I prefer not having to wait 4-5 hours in-between meals. I actually eat well over 5-6 small meals, I eat more like 8-9, but I eat small things throughout the day.
3 meals a day with 2 snacks is pretty decent too.
Losing weight is all about finding what works for YOU. No one is the same.
