According to your line of thinking, then it's "normal" to not engage in much serious physical activity considering most people don't go to a gym, and if they go, don't even know how to exercise correctly.
It's also normal to be fat considering that 60+% of our population is fat.
I don't think eating 5 to 6 times per day is normal according to your or my thinking. I gave up that way of eating several months ago, and I'm glad I did. I'm now surprised that me being a dietitian with degrees in nutrition, that I actually fell for the whole "stoking the metabolism" shit for so goddamn long. Most people can't or don't desire to eat that many times per day. When I used to advise people to do it, they would always-repeat ALWAYS- say, "I don't have time to eat like that," or "I'm at work all day; I can't just stop and eat every three hours." Sometimes they would come flat out and say, "NOT DOING IT!"
There is NOTHING wrong with having control of what you eat. Just because anorexics desire to control their food intake and their dietitian and doctor, doesn't mean that we shouldn't have control of what what us non-anorexics eat. Actually, when I consumed 5 to 6 meals per day, it felt like food was controling ME! I was never satisfied after eating a meal, and before I knew it, I had to eat another meal. By the way, people around me - co-workers, family, friends, women - found this very, VERY annoying.
Anorexics have psychological and psychiatric issues that have little to do with an eating PATTERN. A pattern is besides the point, whether it's 2 or 6 meals per day. I believe that's what you don't understand. There are people who one or two large meals per day who aren't anorexic.
