Endocrine disruptors, chemicals that interfere with hormonal systems, are linked to obesity development. These substances, found in everyday products like plastics, pesticides, and personal care items, can alter the body’s regulation of metabolism, appetite, and fat storage. Exposure to endocrine disruptors, especially during critical periods such as pregnancy or childhood, may increase the risk of obesity later in life. Research suggests that these chemicals can influence weight gain by disrupting thyroid function, insulin sensitivity, and hunger-regulating hormones. Reducing exposure to endocrine disruptors through regulation and safer product alternatives is an important step in obesity prevention.
