The researchers explained that they found that fish oil helps people in losing weight by increasing the elasticity of blood vessel walls and thereby improving the flow of blood to muscles while they exercise.
The researchers stated that they divided the volunteers into four groups. The first group were those taking fish oil and exercise, the second taking who just took fish oil, the third group taking sunflower oil without exercise, and the fourth taking a combination of sunflower oil and exercise.
Professor Peter Howe explained that they had found that the group of people taking fish oil combined with exercise lost more weight than any other group.
They also noted that the group, which took the sunflower oil, which does not contain Omega-3 fatty acids, though they exercised, did not lose any weight, and neither did the two groups that did no exercise including those on fish oil.
Professor Howe said, "When we divided up a number of people in our research programme, we found that those taking fish oil combined with exercise lost significantly more fat mass than any other group in the study." Alison Hill, who supervised the trail, stating that the combination of the two has proven to be an extremely effective method for losing weight, said, "If you take the Omega-3 each day and exercise moderately, our studies show your weight will drop. We were very surprised to see it was so effective, especially since these people were still eating whatever they wanted."
