The large quantities of food waste created by the worldwide food system is a critical issue that is getting major focus owing to its environmental and socio- economic impacts. Internationally, since visibility regarding sustainability, food wastage and impoverishment is on the high, the requirement to understand the behaviour patterns behind reducing food wastage and food insecurity is the need of the hour. In this paper, the authors make an attempt to list and analyse the theories behind the food wastage behaviour in households and to assist future research identify the antecedents of food wastage behaviour. The goal of this paper is to demonstrate a theoretical foundation for household food waste. The paper focuses on the Theory of Planned Behaviour (TPB) and Theory of Reasoned Action (TRA) majorly to explain constructs of behaviour.
