Eating behaviours may be implicated in the increasing prevalence of obesity and metabolic disorders. The Sasang typology, a unique form of traditional Korean medicine, classifies individuals into four constitutional types that differ in a distinctive complex of external manifestations and innate natures, including eating behaviours. Our aim is to portray a picture of the distinguishing characteristics of eating behaviours across Sasang types and to provide suggestions for future studies. Six Korean and one English database were searched to acquire relevant articles. Ten peer-reviewed relevant research articles were found. The extracted data were categorised into the domains of i) food preferences; ii) eating rate; iii) eating initiation and termination; iv) meal size; v) regularity of eating; vi) regular appetite; vii) eating disorders; and viii) psychological factors. Eating rate and meal size were the issues of most concern that more frequently were different among Sasang types. The TaeEum type seemed to have obesity-linked eating behaviours, including a rapid eating rate, large meal sizes, and a strong appetite, whereas those attitudes seemed to be in contrast with those of the SoEum type. The SoYang type shared similarities with both the TaeEum and SoEum types. Future studies should be conducted with more reliable, objective, and quantitative assessment tools such as the Three Eating Factor Questionnaire or the Dutch Eating Behaviour Questionnaire.

OBJECTIVES The present study is aimed at observing the physiological response imagery running with an avatar in 3D virtual reality (VR) and to explore the differences in physiological responses between imagery running with and without an avatar in 3D VR. METHODS We randomly assigned 32 healthy adults to either a group with Avatar (n = 19) or a group without (n = 13). The group with avatar performed imagery exercise with an avatar in 3D VR and the group without Avatar performed it without an avatar in 3D VR. Both groups were instructed to mentally imagine performing running in VR without executing actual physical movements. We recorded electro-physiological data before, during, and after the 20-min intervention. We also measured the participants’ level of presence and intensity of experienced cybersickness. RESULTS In the group with Avatar, all physiological responses increased from the resting to the intervention period. The group with Avatar also showed a higher level of presence and fewer cybersickness symptoms than the group without Avatar. CONCLUSIONS The results suggest imagery running with an avatar in 3D VR might be effective as an alternative exercise.
