Abstract

As overweight is becoming a serious worldwide health issue, a great amount of commercial books, programs and blogs are offering help in establishing healthy eating patterns. A factor that has commonly been blamed for overweight is the growth of portion sizes. This phenomenon of supersizing portions has created a distortion of portion sizes throughout the food industry and has been suggested to lead to overeating. The present study investigates the influence of locomotion and assessment orientations on food consumption quantities in conditions of distorted portion sizes. A survey was conducted in which participants (N = 75) watched a short movie whilst being presented with a distorted food portion. The results of this study show that when controlling for an individual’s level of hunger and movie engagement, locomotion decreases food consumption quantities. To conclude, it is suggested that when food portions are distorted locomotion assists in limiting an individual’s food intake.

Highlights

  • The World Health Organization (WHO) indicated that around 39% of the global adult population was overweight in 2014

  • The results of this study indicate that when controlling for hunger levels and movie arousal locomotion has a significant negative effect on eating behaviour, decreasing food consumption quantities

  • Previous research suggests that increasingly larger portions have been found to cause overeating in a wide variety of settings (Jeffery et al, 2007; Rolls et al, 2004; Rolls et al, 2007), the current study possibly suggests otherwise

Summary

Introduction

The World Health Organization (WHO) indicated that around 39% of the global adult population was overweight in 2014. Eating a super-sized bucket of ice cream or a large plate of creamy mac & cheese is something that most of us are all too familiar with It is such behaviour that fuels the food industry and forms our current eating environment characterized by relatively inexpensive, highly palatable and convenient foods served in large portions (Rolls, Morris, & Roe, 2002). Mirroring these issues, a great amount of commercial books, blogs and programs are available that offer help in establishing a healthy eating pattern. As people are confronted with increasingly larger food portions on a daily basis, we are challenged to maintain an energy intake appropriate to our needs (Ledikwe et al, 2005; Prentice & Jebb, 2003; Young & Nestle, 2002)
