7. Coconut Oil, 8. PUFAs, and 9. MUFAs
Coconut Oil While The Digest Diet recommends keeping saturated fat intake to under 10 percent of total calories, one source sits at the top of the “should enjoy” list: coconut oil. Why? This sweet, rich oil was shown to do some pretty nifty things for abdominally obese women in a 2009 study out of Brazil, including decreasing their waist circumference, increasing beneficial HDL (high-density lipoprotein) cholesterol and improving the ratio of “bad” LDL (low-density lipoprotein) to “good” HDL cholesterol. And in populations where coconut oil is commonly eaten, high cholesterol levels and heart disease are not common. MUFAs In 2006, I uncovered exciting research suggesting that monounsaturated fatty acids, or MUFAs, helped people store less belly fat. Eating a diet rich in olives, olive oil, nuts and seeds, dark chocolate, and avocado has kept my belly lean and my energy up for years! These healthy fats are a mainstay of my diet. PUFAs During my dive into the current research, I came across a small study from the Netherlands that suggests we should also enjoy polyunsaturated fatty acids, or PUFAs, found in fish and in many nuts and seeds. In this study, consumption of a high ratio of PUFAs to saturated fats led to a higher resting metabolism, as well as a greater diet-induced calorie burn. But one clarification: Our focus will be primarily on long-chain n-3 PUFAs, commonly known as omega-3s. Researchers theorize that the weight-loss benefits of omega-3s may be a result of their anti-inflammatory effects (inflammation in the body has been strongly linked to obesity). I also love the fact that these healthy fats are associated with protection from cardiovascular disease and enhanced mood.
