Gains made from weight loss diets and regular exercise can be compromised by chemicals in the utensils and packaging used to prepare and store otherwise healthy food. This is the conclusion of a Harvard-led study that found a correlation between obesogens and weight increase among dieters.
The technical term for obesogens is “perfluoroalkyl substances” (PFAS). They are a class of chemicals that have been used in food wrappers, pots, pans, and other consumer and industrial products for the last 60 years. Called “obesogens” because of their disruptive effect on the body’s normal way of regulating weight, PFASs can lower the resting metabolic rate (RMR) of people, causing their bodies to burn fewer calories while they are at rest. People with low RMR will gain weight more easily unless they adjust their food intake to account for the imbalance in their metabolism.
