I agree that it's pretty different from individual to individual, and most people need to experiment over time to figure out what works best for them. Weight loss, in my experience, has been very much an adventure in being an "experiment of one"!
Personally, I tried the mini-meal thing and hated it. I would much rather eat 3 good-sized meals with an afternoon snack than graze throughout the day. Part of this is physical (I like feeling hungry, and I like feeling full) and part of it is psychological (once my "graze" button has been activated, it is VERY difficult for me to turn it off, which leads to overeating for me).
Try stuff out for a while. See what you like and don't like. And remember, even if your weight loss group gives you advice, you don't have to take it.
They're not in your body, YOU are. So make the best choices for you. After all, the best weight loss program is whichever one you stick with.
