In the new study, Qi Sun, a nutritionist specializing in diseases correlated with obesity, studied the chemicals' relationship to weight gain.

Even the wrappers at burger joints are fattening. After 18 months, half of the weight had been regained on average.

People with higher levels of PFASs in their blood also had more sluggish metabolisms after weight loss. As expected, and as is the case with 95 percent of dieters, the study participants began to regain the weight they lost. The trial involved 621 overweight individuals ages 30 to 70. While the results varied, the study revealed that women with the highest levels of PFASs in their systems had gained the most weight since their diet.

Researchers found that PFASs - also known as "obesogens" - were linked to a slower resting metabolic rate, because they interfere with body weight regulation.

It's unclear exactly how the chemicals affect a person's metabolism, Sun noted.

Chemicals used in food wrappers, non-stick pan coatings and clothing may boost body weight by interfering with metabolism, especially in women, United States researchers said Tuesday. Scientists say that the chemicals - which were already suspected of causing high cholesterol and possibly cancer - have been linked to rapid weight gain in some patients.

"Most folks think of obesity as being a result only of eating too much of the wrong foods and not getting enough exercise", David Carpenter, director of the Institute for Health & the Environment at the University at Albany, State University of NY, told Live Science.

"Obesity, and chemicals that increase risk of obesity, pose a major health problem", Carpenter said. Sun added that it's "basically impossible" to avoid the non-stick chemicals because they are used in so many items.

The Environmental Protection Agency has more information on where you can find PFASs.
