I mention epigenetics because I know a few people, who like you, have lost a significant amount of weight. They also say that they pretty much can't eat until they are full or even really satisfied if they want to stay the same weight. I suspect that all of that weight gain (and the foods that contributed to it) have skewed their sense of satiety somewhat compared to what it was before and/or compared to a "normal" person.
