Non-Classical Aspects of Obesity Pathogenesis and Their Relative Clinical Importance for Obesity Treatment
Summary
This review examines non-classical factors contributing to obesity beyond diet and exercise, including endocrine-disrupting chemicals, sleep quality, psychotropic medications, and light exposure at night, clarifying their clinical relevance for obesity prevention and treatment.
Obesity is a chronic disease and a major public health problem due to its association with non-communicable diseases and all-cause mortality. An increased energy intake and decreased physical activity have been long recognized as the classical parameters that contribute to the development of obesity. However, several other, non-classical factors have also been associated with obesity through various complex mechanisms. Some of them are diet related, such as diet quality, dietary habits and speed of eating. Other factors are non-dietary, such as endocrine-disrupting chemicals, sleep quality and quantity, psychotropic medications and light at night. The scope of the present narrative review is to address these non-classical factors that are implicated in the pathogenesis of obesity, to clarify their potential role in the management of obesity and, where possible, to provide some practical clinical recommendations.

Obesogens: How They Are Identified and Molecular Mechanisms Underlying Their Action
Researchers reviewed the science behind obesogens, a class of endocrine-disrupting chemicals that promote fat storage and metabolic dysfunction. These compounds act through multiple pathways including disrupting adipose tissue function, altering gut microbiome composition, and interfering with hormonal signaling, with effects that can persist across generations. The review highlights the need for improved chemical screening methods to identify obesogenic substances and protect public health.
Weighty Consequences: Pollution’s Hidden Weight in the Obesity Epidemic: A Narrative Review
This narrative review examines evidence linking environmental pollutants—including air pollution, persistent organic pollutants, and microplastics—to obesity and metabolic disruption. It highlights biological mechanisms by which pollutants act as obesogens and calls for pollution to be considered a driver of the global obesity epidemic.
Environmental Epigenetics and Obesity
This review examines how environmental and dietary factors drive epigenetic changes that contribute to obesity, highlighting the role of nutritional interventions in regulating gene expression and metabolic responses linked to chronic non-communicable diseases.
A review of environmental metabolism disrupting chemicals and effect biomarkers associating disease risks: Where exposomics meets metabolomics
This review examines how environmental chemicals, including contaminants associated with plastics, can disrupt human metabolism and contribute to conditions like obesity and diabetes. Researchers mapped the connections between chemical exposure and changes in metabolic biomarkers that signal disease risk. The study highlights the emerging field of metabolism-disrupting chemicals and the importance of understanding how everyday environmental exposures influence long-term metabolic health.
Impact of Chemical Endocrine Disruptors and Hormone Modulators on the Endocrine System
This review examines how endocrine-disrupting chemicals, including those found in plastics, interfere with the body's hormone systems through both direct and indirect pathways. Researchers found that long-term exposure to these substances can affect reproductive health, metabolism, and development, with physical stressors like light and temperature also playing a role. The study highlights the complexity of endocrine disruption and the need for broader research into non-chemical factors as well.
