I think 6 meals a day is more a mental thing when cutting. If you know that your next meal (if you can call it a meal) is only a few a hours away, you know you can make it and not snack/panic.
What has worked for me is just being disciplined. Training and diet remained relatively the same, just less calories and more cardio. When the weight is coming off fast, your body will plateau. So you don't want to blow your wad right at the start of the cut. Reduce calories in stages (every 2-4 weeks) and the same with cardio doing the reverse.
Again with the mental challenge, the hardest part is getting about 3 weeks in and cutting out things you enjoy. Once you've made it to the 3 week mark, you'll be set in your new routine.
Reverse dieting is also a big part of it that's often overlooked. You basically want to do what you've done in stages in reverse, but in half the time. So say you were reducing calories by 200 every 2 weeks. Increase calories by 200 every week until you're back to maintenance. I did this last year and barely put on any weight by the time I was back to maintenance.
