When researchers took subjects who were on blood pressure medication and had them use sesame oil as the only edible oil for 45 days, there was a significant reduction in body weight and body mass index. Blood pressures also dropped significantly. In addition, they found that levels of antioxidants were much higher in the sesame oil group. The only catch is that if you stop the sesame oil diet, it all comes back.
Note: Make sure the oil is refrigerated so it does not go rancid. Eating rancid oil is extremely bad for you. Also, a number of people are sensitive to sesame oil, so if you decide to try this, discontinue if any new symptoms develop.
