Obesogens: Chemical Compounds That Disrupt Metabolism and Promote Obesity
Environmental health research · Various studies (2006)
Certain synthetic chemicals, termed obesogens, directly promote weight gain and metabolic dysfunction by interfering with the body's hormonal regulation of appetite, fat storage, and energy expenditure.
Core Concepts
The Problem
Obesity rates have risen beyond what can be explained by diet and exercise alone.
The Claim
Environmental exposure to obesogenic chemicals contributes to obesity independent of caloric intake.
Key Evidence
- •Animal studies show that prenatal exposure to obesogens leads to higher fat mass later in life.
- •Epidemiological studies link urinary levels of phthalates and BPA to increased BMI in humans.
Practical Implication
Reducing exposure to obesogens through food choices, product selection, and public policy may be necessary to address the obesity epidemic.
Nuance & Limits
Obesogens are not the sole cause of obesity; they interact with diet and lifestyle to shift metabolic set points.
