Abstract

The prevalence of childhood and adolescent obesity has risen dramatically over recent decades, particularly in rapidly developing countries undergoing significant dietary transition. Qatar now has one of the highest rates of childhood overweight and obesity globally, coinciding with increased availability and consumption of processed and ultra-processed foods (UPFs). Although associations between UPF consumption and obesity are well established, the biological and behavioural mechanisms underpinning this relationship have not previously been synthesised within the context of Qatar.
To provide a structured narrative review of the evidence describing the mechanisms through which processed and ultra-processed foods contribute to obesity among children and adolescents, while contextualising these findings within Qatar's changing food environment.
Evidence consistently demonstrates that processed and ultra-processed foods promote excessive energy intake through five interconnected mechanisms: high energy density and increasing portion sizes; impaired appetite and satiety regulation; displacement of nutrient-dense whole foods; activation of reward pathways that encourage compulsive eating behaviours; and neurobiological and metabolic adaptations that may reinforce long-term overconsumption. Although much of the available evidence originates from Western populations, similar dietary transitions are occurring across Qatar and the wider Gulf region, suggesting these mechanisms are highly relevant to the local context. However, important limitations remain, including the relative scarcity of longitudinal and intervention studies conducted within Middle Eastern populations.
Addressing childhood obesity in Qatar requires interventions that extend beyond calorie reduction to target the broader food environment and dietary quality. Strengthening school nutrition policies, promoting traditional dietary practices, improving nutrition education, and reducing children's exposure to ultra-processed food marketing should form key components of future public health strategies. Further longitudinal research conducted within Qatar is required to better understand the long-term health consequences of increasing UPF consumption among young people.
