Counting the cost of chemicals in the home

What causes obesity?


Obesogens, a group of endocrine disrupting chemicals that adversely affect normal hormonal functions in the body, are starring in academic studies about the causes of obesity. According to Amanda Janesick and Bruce Blumberg from the University of California, obesogens play an important part in fat cell functioning, letting the body know when to store fat, and influencing the body’s hunger drive.


While a growing number of links have been made between chemicals and obesity, further research is needed to find out the extent of human susceptibility, including the levels at which obesogen exposure can take effect.

Where are obesogens in the home?


  • Phthalates – found in shower curtains and vinyl flooring,
  • Fungacides used in antifungal treatments on wood and textiles.

How do you avoid obesogens?

Even though the science is still developing, choosing products and materials without obesogens is a good idea if you want to avoid potential risks. There are a growing number of alternative options available for a lot of chemical-laden products, many of which are cost-effective and environmentally-friendly. Taking positive steps to upgrade air quality is another way to reduce potential exposure. Air quality can be improved by using proper ventilation and appropriate air filtration.

It’s well established that obesity comes from a combination of factors, including lifestyle choices. But mounting evidence seems to suggest that chemicals like obesogens can also contribute to weight gain. If the experts are right, the future of weight management could be vastly different, with much greater focus on environmental factors like the products in your home.
