  • Description: Abstract The article deals with a relevant theme regarding problems related to food supply. The losses accounted at production process and consumer food waste justify research on the subject. The purpose of this paper is to explain food waste intention using the theory of planned behavior (TPB) as a theoretical lens. In addition to measuring the influence of attitudes, social norms, and perceived behavioral control on intention, additional constructs were introduced into the model. Affect, planning routines, food surplus, and environmental concerns were incorporated to fit a logistic regression model, presenting the probability of food waste occurrence as a proxy for the probability of intention to waste. An online questionnaire was developed to collect data from consumers in the Midwest of Brazil. The sample consisted of 419 responses. As a result, it was found that food waste occurred more in affluent households, fewer in number, better categorized as “waste people” by family and friends, and less adept at reusing leftovers or saving food. In general, the affective memory related to food corroborates the desire for an abundant table, making waste acceptable. This information is useful for the construction of action plans, public and private, aimed at behavioral changes related to waste. Resumo O artigo trata de problemas relacionados ao abastecimento alimentar. As perdas do processo produtivo e o desperdício no consumo justificam a realização de pesquisas no tema. O objetivo do artigo foi explicar a intenção em desperdiçar alimentos à luz da Teoria do Comportamento Planejado (TPB). Além da medida da influência de atitudes, normas sociais e controle comportamental percebido sobre a intenção, construtos adicionais foram introduzidos no modelo. O afeto, o planejamento de rotina, o reuso de sobras e as preocupações ambientais foram incorporados para o ajuste de um modelo de regressão logística, apresentando a probabilidade de ocorrer desperdício como proxy para a probabilidade da intenção em desperdiçar. A coleta de dados ocorreu com aplicação de questionário online junto a consumidores do Centro Oeste brasileiro. A amostra constituiu de 419 respostas. Como resultado, constatou-se que o desperdício aconteceu mais nos domicílios abastados, menos numerosos, melhor categorizados como “desperdições” pela família/amigos e menos hábeis em reutilizar sobras ou guardar comidas. De modo geral, a memória afetiva do alimento corrobora o desejo por mesa farta, tornando o desperdício aceitável. Essas informações são úteis para a construção de planos de ação, público e privados, visando mudanças de comportamento relacionadas ao desperdício.
