I eat about 3/4 to 1 cup. I am full, but not in the sense of the word that I was used to. I do not feel gorged, uncomfortable, stuffed, etc. The full signal for a bandster is pressure behind the breastplate. This is how we know it's time we stop or face pain.
I have had one fill, and I find that my meals prevent me from being physically hungry for 3 to 4 hours, depending on what I ate. It is strongly suggested that we eat protein first during the meal. Protein takes much longer to break down in the stomach than carbs do, so it prevents hunger for a longer time.
The term that Jack has really emphasized is satiate.
(a clip of Webster's definition: Satiate may sometimes imply only complete satisfaction but more often suggest repletion that has destroyed interest or desire.)
This would best describe what I feel after eating. I am not "full" in the old sense of the term, but my interest in food is gone.
Here is another thread in which this topic was discussed.
