PurposeThe purpose of this systematic literature review (SLR) is to analyse which consumer behaviours are more evident in relation to food waste, in addition to seeking to identify which types of food are most wasted in homes and the methods which have been used by studies for such particularities. In this paper, it was possible to identify the universe of consumer characteristics covering the main contributions to the development of this theme with different points of view.Design/methodology/approachTo achieve this goal, the authors performed a SLR according to well-established guidelines set. The authors used tools to partially support the process, which relies on a four-member research team.FindingsThe authors report on 49 primary studies that deal the lack of planning, excessive purchases and the non-reuse of food leftovers by the consumer as the characteristics most evidenced as a consequence of food waste. Furthermore, fruits, vegetables and bread are the most wasted food. Regarding the most used research methods, some studies in this SLR use the qualitative method, but mostly food waste is analysed using the quantitative method.Originality/valueThis SLR is different because it seeks to group different aspects of food waste, mapping not only the consumer’s behavioural characteristics but also seeking to identify the most wasted food. The research contributed to finding theoretical gaps on the subject in favour of reducing waste, based on the findings that demonstrate causing food waste.

Purpose -The central objective of this research was to analyze the moderating role of chronic regulatory focus in impulse consumption when individuals are exhausted of self-control energies (ego depletion). In addition, we sought to examine the relationship between regulatory adjustment and the affective and cognitive processes of impulse decision making.Design/methodology/approach -The study was performed through an experiment. Data analysis was done using the Johnson-Neyman floodlight technique, which is recommended when the independent variable is continuous, so as not to transform it into a dichotomous variable, thus avoiding the loss of information.Findings -The results provide evidence that individuals with a profile of being vigilant about impulse decisions (focus on prevention), that is, with greater self-control in their decisions, end up spending more self-control energy than individuals who do not have this concern (focus on promotion), resulting in higher impulse consumption.Originality/value -The main contribution is a counterintuitive result that individuals who should be better prepared to withstand impulse consumption, with greater self-control, end up consuming more on impulse because they expend more energy in an attempt to control themselves.

PurposeThis study seeks to investigate the influence of the theory of planned behavior (TPB), of the conscious consumption intention and of the consumer ethical considerations, on Slow Fashion Consumption in the region known as Agreste Pernambucano, in Brazil, which is known for being an apparel manufacturing area.Design/methodology/approachTo achieve this purpose, descriptive quantitative research using non-probabilistic sampling was conducted. Data were collected through an online survey and distributed through the snowball technique. The sample consists of 486 respondents and relies on structural equation modeling for data analysis.FindingsThe results highlight that the Slow Fashion Consumption, in the scope of Local Productive Arrangement (LPA) of clothing manufacturing in the Agreste region, is influenced by the intention of conscious consumption, the ethical considerations in consumer behavior and the perceived behavioral control. Moreover, the results highlight the role of the influence of subjective norms both in the attitudes of consumers and the intention of conscious consumption.Originality/valueThe primary contribution of this study is to demonstrate that perceived behavioral control is positively associated with Slow Fashion Consumption, which, in turn, shows that respondents believe they have control over their sustainable actions.
