Initial research suggests a class of hormone-disrupting chemicals dubbed “obesogens” (such as bisphenol A [BPA] and phthalates) may trigger excess fat-cell production and storage. Environmental toxins like organophosphate pesticides and flame retardants also slow metabolism, says Walter Crinnion, ND, of the Southwest College of Naturopathic Medicine in Arizona.


Rice bran fiber. This mostly insoluble fiber binds to industrial contaminants in the bile. Load up on whole-grain brown rice, or mix 1–2 tablespoons rice bran fiber powder into a beverage with each meal.

Green tea. It helps the liver clear toxins from the blood and fat, and mildly accelerates weight loss. In a 2010 study, obese people who drank four 8-ounce cups of green tea daily for eight weeks lost 5 1/2 pounds more than the placebo group.


Some personal care products. Those with artificial fragrances may contain phthalates.

Food and beverages packaged in plastic. In particular, steer clear of #7 plastics, which often contain BPA. Store food and beverages in glass or stainless steel.


Chlorophyll. Found in green vegetables and algae, chlorophyll helps you excrete environmental pollutants. Take 2–4 grams Chlorella pyrenoidosa powder daily, and eat lots of organic spinach, Swiss chard, mustard greens, parsley, and cilantro.

Whey protein. This all-purpose supplement boosts the detoxifying liver enzyme glutathione, promotes satiety, and helps increase muscle mass and metabolism. Study subjects who drank 48 grams of whey 90 minutes before a meal ate less and felt full longer. Add 2 scoops of whey protein powder to a beverage before meals.


Take a 30-minute sauna at least once a week. Sweating helps mobilize toxins stored in fat.
