Portion Size: Latest Developments and Interventions [PDF]
Current Obesity Reports, 2017 The aim of this review is to provide an overview of (1) underlying mechanisms of the effect of portion size on energy intake, (2) external factors explaining the portion size effect and (3) interventions and measurements aimed at food portion size.Previous studies have shown that portion sizes have increased in recent decades. Many experimental studies

FOODCAM: A Novel Structured Light-Stereo Imaging System for Food Portion Size Estimation [PDF]
Sensors, 2022 Imaging-based methods of food portion size estimation (FPSE) promise higher accuracies compared to traditional methods. Many FPSE methods require dimensional cues (fiducial markers, finger-references, object-references) in the scene of interest and/or ...

An exploratory study on portion size estimation errors: psychological correlates of portion size estimation errors in a non-clinical sample with normal-weight [PDF]
Eating and Weight DisordersPurpose Accurate perception of food portion sizes is implicated in healthy eating, yet little is known about psychological correlates of portion estimation in non-clinical, normal-weight adults. This exploratory study examined whether consumption intent (
