(redirected from Obesogens)


An exogenous substance that alters lipid homeostasis and fat storage, changes metabolic setpoints, disrupts energy balance or modifies the regulation of appetite and satiety, promoting fat accumulation and obesity.

Mechanisms of action
Alteration of metabolic sensing, neuroendocrine effects, cell signalling, dysregulation of steroid hormones.

Pharmaceutical obesogens
• Metabolic sensors—Act on PPAR-gamma receptor (e.g., thiazolidinediones, rosiglitazone);
• Sex steroid dysregulation—DES caused obesity in adults;
• Central—Act on neurotransmitter receptors (e.g., SSRIs, antidepressants).

Environmental obesogens
• Organotin;
• Xernobiotics.

Although genetics, diet, and exercise all contribute to obesity, recent studies have shown that prenatal exposures to "environmental obesogens," including bisphenol A, phthalates, organotins, and perflourinated compounds may increase the risk of obesity in children (Janesick and Blumberg 2011).
