I think the rwgen system is ok. The choice of the higher levels in terms of wording might not be completely ideal but people generally understand. We could change "satisfied" to be "slightly hungry" but I think it is supposed to less represent your hunger and more your health. Glutton would be eating to full satisfaction all the time, satisfied would be eating enough to keep away the hunger pangs...... Etc.
