Is Obesity caused by calorie underestimation? a psychophysical model of meal size estimation

---

Sixty-five percent of US adults are either obese or overweight. Many policy makers and concerned consumer groups have alleged that this epidemic is being fueled by a combination of increasing portion sizes in restaurant meals coupled with a virtual absence of intuitive understanding that larger portions contribute more calories. In this research, the authors develop and test a psychophysical model of meal size estimation and use it to show that the association between body mass and biases in calorie estimations is a spurious consequence of the tendency of overweight people to consume larger meals. In three laboratory studies and in one field study, the authors find that meal size estimations follow a compressive power function of actual meal size. They further show that the estimations of people with a low and a high body mass index (BMI) follow the exact same psychophysical function, whether they are made before or after intake, for self-selected or randomly selected meals. The final analyses address the public health implications of psychophysical biases in meal size estimations by studying the estimations, forecasts, and consumption decisions of professional dieticians.Printed Journal
