You may have heard about PFAS in the news, but what exactly are they? Known as “forever chemicals,” PFAS (Per- and Polyfluoroalkyl Substances) are man-made chemicals that have been used for decades in products designed to resist heat, water, and oil.
While they make life more convenient, they also pose serious risks to your health and the environment.
Let’s dive into what PFAS are, how they can affect your health and weight, and which items you might want to avoid to limit your exposure.
What Are PFAS?
PFAS, are a large group of over 9,000 synthetic chemicals used in various industries and consumer products. They are incredibly stable, which means they don’t break down in the environment or in our bodies easily—hence the nickname “forever chemicals.”
Common Uses of Forever Chemicals:
- Non-stick cookware (e.g., Teflon-coated pans)
- Stain-resistant carpets and upholstery
- Waterproof clothing
- Food packaging, especially grease-resistant wrappers
- Firefighting foams
- Industrial processes
While their resistance to degradation is beneficial for manufacturing, it also makes them a persistent pollutant in water, soil, and air.
How Do PFAs Affect Health and Weight?
Exposure to PFAS has been linked to a range of health issues. Here’s why you should be concerned:
Health Impacts:
- Hormonal Disruption: They interfere with endocrine function, affecting hormones that regulate metabolism and reproduction.
- Immune System Suppression: Studies suggest PFAS can reduce your body’s ability to fight infections.
- Increased Risk of Cancer: Certain types of forever chemicals have been associated with kidney and testicular cancer.
- Developmental Issues: Prenatal and childhood exposure can impact growth and development.
- Cholesterol Levels: PFAS exposure is linked to higher levels of “bad” LDL cholesterol.
Weight Implications:
Forever chemicals have been shown to alter metabolism, leading to weight gain and difficulty in losing weight. A 2018 study in JAMA Network Open found that higher forever chemical levels were associated with slower metabolic rates in individuals trying to lose weight.
Emerging research shows that forever chemicals can interfere with metabolism, potentially leading to weight gain and difficulty losing weight. They are known to affect lipid metabolism and insulin sensitivity, contributing to obesity and metabolic disorders.
A study in Obesity journal discusses the connection between forever chemical exposure and weight gain over time.
When the body is overloaded with toxins, it’s unable to metabolize fat as a fuel source, making it harder to lose weight and be healthy in the process. That’s why I recommend doing a metabolic detox a few times a year to reduce toxins and inflammatory weight. In this case I recommend my Reset Cleanse.
