If you thought losing weight would mean giving up all your indulgences, look no further than dark chocolate. Louisiana State University researchers found that gut microbes in our stomach ferment chocolate and boost our body's production of gut-healthy polyphenolic compounds, including butyrate, a fatty acid that encourages the body to burn fat as fuel and turns off genes linked to inflammation. (Add fruit to the chocolate to boost fermentation and the release of the compounds.) Make sure you go with chocolate that has a cacao content of 70 percent or above—these have the highest concentrations of antioxidant polyphenols.
Known as "forbidden rice" because only emperors were allowed to eat it, black rice may be the cheapest source of antioxidants around. According to the American Chemical Society, black rice has more antioxidants than a spoonful of blueberries, with more satiating fiber, more vitamin E, and less sugar. More antioxidants mean less inflammation, which means less fat storage for you.
