Summary
This comprehensive narrative review, authored by an international consortium of environmental health and metabolic disease experts, synthesises evidence for causal relationships between chemical exposures and obesity development. The authors move beyond epidemiological associations to examine mechanistic pathways through which endocrine disruptors and other environmental chemicals may promote adipogenesis, metabolic endotoxaemia, and weight gain across critical developmental windows. The work supports the hypothesis that chemical contamination of food, water, and consumer products represents an underrecognised obesity risk factor warranting public health and regulatory attention.
Regional applicability
The findings are relevant to UK food safety and environmental health policy, particularly regarding regulation of chemicals in food contact materials and agricultural residues. However, the review does not address UK-specific exposure levels or agricultural practices, limiting direct applicability to domestic farming system recommendations.
Key measures
Mechanisms of chemical-induced obesity; adipogenesis and metabolic dysregulation; evidence quality assessment across experimental and human studies; exposure-outcome associations across developmental windows
Outcomes reported
The study examined and synthesised evidence for causal links between environmental chemical exposures (endocrine-disrupting chemicals, persistent organic pollutants, metals) and obesity development across multiple biological pathways and life stages. The authors assessed mechanistic evidence, experimental models, and epidemiological data to establish causality rather than association alone.
