Edelman published a study with army recruits38 showing that the more food that was put on their plate, the more they ingested. In the last 10 years, a considerable amount of laboratory data has substantiated the robustness of the portion size effect. 34 The portion size effect is neither trivial nor transitory. 75 A recent study by Rolls110 demonstrated the effect of changing portion size lasts at least 2 days, and a recently completed study in our lab showed the effect of decreasing portion size for lunch remained for 2 weeks.

In this chapter, I have offered an alternative to commonly held views by suggesting that food intake serves to regulate energy production, not body fat content or energy balance. This framework explains findings that are anomalous for more traditional theories and in doing so erases misperceptions and avoids premature abandonment of regulatory explanations for the control of food intake. Acknowledgments The author thanks Charles Horn, Marcia Pelchat, Danielle Reed, and Michael Tordoff for their helpful comments and stimulating discussions during the preparation of this chapter.
