STORY AT-A-GLANCE
- The term obesogen is used for endocrine-disrupting chemicals that trigger permanent and sometimes transgenerational changes to fat cells
- In animal studies, changes from obesogens that slow metabolic rate and increase fat storage may be found up to four generations later
- The percentage of infants younger than 24 months who are obese grew significantly during the time obesogens became ubiquitous in the environment
- Rising weight is associated with disabling and sometimes deadly health challenges, increasing health care spending 29% from 2001 to 2015
- Obesogen chemicals are found at home and work, but you can reduce exposure using water filters, eating whole foods, ditching nonstick products and avoiding plastics and packaged foods
