The relationship between alcohol consumption, dietary habit and obesity: A review

Obesity around the world is a major public health concern. Media reports and statistics indicate that most nations around the world are not spared from this concern and are disproportionately affected. The purpose of this paper is to re-examine prior researches conducted in this domain and to further explore the associated factors that predict variation in body mass index (BMI). This review is an attempt to close the gap in literature using time discounting and further extends health economic theoretical model to provide a better understanding of the development of obesity. Specifically, this paper reviews the effect of alcohol consumption and dietary habits and its effect on BMI. Prior researches suggest that dietary habits factor could play a mediating role between alcohol consumptions on variation in BMI. Importantly, a conceptual model is proposed and is adapted from the health economic theory (HET), following, which, a set of propositions are developed, and directions for future research are recommended.
