2018 Study: Obesogens: chemicals commonly found in the environment may disrupt the way hormones operate, potentially leading to weight gain

"Eat less, move more" is the simple way to stay slim, but some scientists now suspect body weight is much more complex.

One area of research is "obesogens" which are chemicals absorbed from the environment and food that are thought to disrupt the way hormones operate, potentially leading to weight gain.

Research by Harvard University found that women (men less so) struggled to maintain weight loss after higher levels of perfluoroalkyl substances (PFASs) were found in their blood.
