Study links fluorinated chemicals to more weight gain and slower metabolism after people dieted
Unregulated chemicals increasingly found contaminating U.S. water may hamper people’s ability to lose weight, according to a study released today.
The study is the first to link the group of chemicals, PFASs [perfluoroalkyl substances], to weight gain and obesity, and suggests that exposure to the toxics may counteract weight loss efforts by slowing down people’s metabolism.
The chemicals—already associated with other health problems including cancer, hormone disruption, immune dysfunction and high cholesterol—continue to make headlines as they contaminate waterways across the U.S., including high profile pollution hotspots in Michigan and North Carolina.
People with slower metabolism burn fewer calories and are more prone to weight gain and obesity. Obesity is a global health problem: In the U.S., roughly 37 percent of adults and 17 percent of children are obese.
