For more than a decade now we have been alerting readers about research findings linking common chemicals in our food/personal care/home care products and increased weight gain. This latest study replicates the findings of earlier studies, showing that increases in weight gain following dieting, especially among women, is linked to common chemical substances called PFASs. These chemicals (known as “obesogens”) are commonplace today and have been found in food packaging and a variety of cosmetic and personal care/home care products. The chemicals have been linked in numerous scientific studies with cancer, hormone disruption, immune dysfunction, high cholesterol, and obesity.
“Obesogens have been linked with excess weight gain and obesity in animal models, but human data has been sparse. Now, for the first time, our findings have revealed a novel pathway through which PFASs might interfere with human body weight regulation and thus contribute to the obesity epidemic.”-Qi Sun, researcher and assistant professor, Department of Nutrition at Harvard Chan School.

Perfluoroalkyl substances and changes in body weight and resting metabolic rate in response to weight-loss diets: A prospective study.

SOLUTIONS: To reduce the levels of PFAS in your body, avoid consuming fast food and highly processed foods as these chemicals have consistently been found in the wrappers and packaging of both types. In addition to preparing your own meals and snacks using fresh, whole ingredients, also consider making your own personal care products when possible, or choosing organic versions over mainstream, commercial products.
In addition to the solutions above, research has shown that getting plenty of fresh air, exercise and proper sleep will help to regulate metabolism and strengthen the body’s ability to maintain healthy weight.
