Those who gained the most weight back had the highest levels of PFAS chemicals, researchers found. And perhaps even more alarming, higher background PFAS exposures had an even greater effect on weight gain than the diet, researchers found. "The results suggest that PFOA and PFHxS may cause weight gain among people with obesity in weight loss programs," the researchers concluded. Grandjean and colleagues previously examined weight loss and weight gains in people from Massachusetts and Louisiana and found PFAS exposure was linked to gaining weight back after initial loss via dieting.
