Obesogens: Chemicals That Make Losing Weight Even Harder

Ever heard of obesogens? I hadn’t – until I came across an article blaming them as one reason individuals may find it hard to lose their “last 10 pounds.” While it’s been proven time and again that a key factor to weight loss is eating healthy and exercising, experimental studies are showing that there may be environmental factors – endocrine disrupting chemicals (EDCs) - that cause the endocrine system (which produces the hormones that regulate our bodies) to go awry.

The average American is exposed to anywhere between 10 and 13 pesticides a day (through food, beverages, and drinking water), and 9 of the 10 most common pesticides used are EDCs. While additional research needs to be conducted to form concrete conclusions about their effect on weight loss, limiting exposure to these pesticides for just five days can reduce your exposure to non/near non-detectable levels. How?

1. Know when eating organic is worth it. There are two lists to be mindful of, The Dirty Dozen and The Clean Fifteen. Knowing which list your common fruits and vegetables fall under will help you decide whether or not to buy organic. Those items on the former list contain the highest levels of pesticides; items on the latter show little pesticide residue when tested.
   
   The Dirty Dozen (starting at the worst): celery, peaches, strawberries, apples, blueberries (domestic), nectarines, sweet bell peppers, spinach, kale/collard greens, cherries, potatoes, and grapes (imported).
   
   The Clean Fifteen: onions, avocado, sweet corn (frozen), pineapples, mango, sweet peas (frozen), asparagus, kiwi fruit, cabbage, eggplant, cantaloupe (domestic), watermelon, grapefruit, sweet potatoes, and honeydew melon.
2. Don’t eat plastic. Don’t roll your eyes – we all do it! But, you can minimize your exposure to the chemicals found in plastic by: 
   
   • Stop heating up your food in plastic containers and/or putting plastic containers in the dishwasher. Boiling liquids in them increases leeching of obesogens into the foods they contain.
   • Avoid buying fatty foods wrapped in plastic wrap (generally made from PVC, unlike at home plastic wrap, which is made from polyethylene), as the fatty tissue in these foods can store EDCs.
   • Cut down on canned goods and look for the same items in pouches instead, as many cans contain major obesogens.
3. Choose foods from the pasture.
   
   Grass fed animals, as opposed to confined, grain-fed ones, contain no EDCs (and carry a lot more vitamins).
   
   When choosing fish, stick with small, lean fish, such as anchovies, Atlantic herring and mackerel, and wild-caught Alaskan salmon.  Remember: Big fish eat smaller fish, therefore carrying a much higher toxic load.
4. Filter your water.
   
   Most people agree that it tastes better anyway, but filtering your water will help to get rid of pesticides and chemical pollutants found in tap water. Make sure it meets the NSF/American National Standards Institute’s standard 53 (it should say this on the packaging), so that you are treating your water for health and aesthetic concerns.

Just remember: Using these guidelines to make informed decisions and minimize exposure to obesogens should be complementary to a healthy diet and exercise program – as both are key elements to successful weight loss and weight maintenance.
