another thing is your stomache expands, you have probably "trained" it not to eat to much. but we are humans, and we can be "trained" to do any thing that we put our minds to, we just have to figure out how. one way to make your self hungrier, is to eat as soon as you get up. the sooner you eat, the sooner you will be hungrier. and as for eat past when you feel full, i dont know about that , i mean shoving food down your throat with a fork instead of chop sticks already forces this, it takes you a cupple minutes to feel full when your eating.
in my experience, eating more freaquently leads to faster metabolism, where as eating larger meals at a time leads to "growing" your stomache size. but you dont need to do it to fast. unless you have direct time constraints for which you are trying to reach that weight.
