Obesogen : Toxin and obesity

What is Obesogen?

Obesogens are chemicals that disrupt the body's normal homeostatic controls in such a way as to promote adipogenesis and lipid accumulation.

These agents can act by any of several mechanisms such as

  • disrupting RNA transcriptional control

  • interfering with normal activity of steroid hormones

  • disrupting the normal metabolic balance

They are chemicals to which individuals are exposed on an almost continuous basis, in the foods and beverages they consume and the products they use.
