The article below is about a recent study that found eating the right fats could actually help reduce weight. The basic finding is that oleic acid is transformed in the small intestine into a chemical that sends a signal to the brain that you are full. Olive oil is up to 80% oleic acid which is a monounsaturated fat. The article focuses on the prospect on using this finding to create a new class of anti-obesity drugs. But why not just take the natural drug of real extra virgin olive along with all its other anti-oxidant benefits?
