Raises a question worth testing. It does not answer one.
This is a narrative review proposing microplastics and nanoplastics as potential environmental contributors to obesity via multiple biological pathways. The evidence base comprises experimental and animal studies showing alterations in lipid metabolism, body weight, insulin sensitivity, and inflammatory responses; human causal evidence is acknowledged as insufficient, and the authors call explicitly for well-designed human studies to establish causation.
Narrative review. General population exposed to microplastics and nanoplastics; focus on mechanistic implications for obesity pathogenesis..
MNPs detected in food, drinking water, air, and human biological samples Emerging evidence from experimental and animal studies reports alterations in lipid metabolism, body weight, insulin sensitivity, and inflammatory responses following MNPs exposure Pathogenesis of obesity cannot be fully explained by lifestyle factors alone
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
This review does not provide direct clinical guidance. Clinicians should recognize that human evidence linking microplastics/nanoplastics exposure to obesity remains preliminary, and current obesity management should continue to be informed by established lifestyle and genetic factors until causal human studies are completed.
A narrative review synthesizing experimental and animal evidence of a potential mechanistic link between microplastics/nanoplastics exposure and obesity, raising questions rather than establishing causal human evidence.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Obesity is a rapidly growing global health concern. The pathogenesis is complex and cannot be fully explained by lifestyle factors alone. The increasing attention towards this concern has finally been directed towards environmental contributors which may influence metabolic regulation. Microplastics and nano-plastics (MNPs) are ubiquitous environmental pollutants that have recently been detected in food, drinking water, air, and human biological samples, raising concerns about their potential role in metabolic disorders, including obesity. Chronic exposure to MNPs may interfere with metabolic homeostasis through multiple biological pathways. Emerging evidence, including both experimental and animal studies, reports alterations in lipid metabolism, body weight, insulin sensitivity, and inflammatory responses following MNPs exposure. This review synthesizes current evidence linking MNPs to obesity, highlighting key exposure pathways, mechanistic insights, and gaps in existing research. Understanding the metabolic implications of MNPs exposure is essential for advancing obesity research and informing future public health strategies. Further well-designed human studies are needed to clarify causal relationships and guide preventive interventions.
