From an energy intake perspective, it has been argued that underestimation of the increasing sizes of restaurant and home-cooked meals is contributing to the rising obesity rates in the United States (1-4). Although nearly all persons underestimate their calorie intake, considerable evidence indicates that the bias is much worse for those who are overweight (5-8). Clinicians and researchers have proposed a wide range of possible reasons, leaving recent reviews to conclude that the cause of this bias is “unclear” (9) and, more fundamentally, that “we still need to understand why people misreport food intake” (6).
