Are weight control and food waste a trade-off?: A clustering of pre-meal portion planning and plate-clearing behaviors among Japanese adult consumers.

ABSTRACT:

Purpose

Plate-clearing behavior (PCB), a maladaptive behavior in a food environment characterized by large, energy-dense portions of food, may contribute to weight gain over time. If a portion size is selected that causes overeating, a trade-off exists between food waste and weight gain due to PCB. However, patterns between PCBs and pre-meal portion planning to prevent overeating (PPP-O) remain overlooked. This study aimed to identify these patterns in various meal situations and describe the demographic, anthropometric, psychological, and lifestyle-related characteristics of those following each pattern.

Methods

Overall, 1,707 Japanese participants responded to a web-based anonymous questionnaire in February 2023. Cluster analysis was performed to identify patterns in PPP-O
