I agree, CherryQuinn. While I was a chubby child during puberty, I don't have a huge appetite and I didn't really get heavy until trying fast food (thank my ex husband for that introduction WHILE I was pregnant, lol).
If some of us were just more nutritious with our choices, we may find that we don't have much of a hunger/appetite problem at all, and that we are much more intuitive than we thought.
ETA: I naturally follow more of a volumetrics eating style as Tripswitch mentioned.
HERE IS A LINK explaining how I do it.
