Lineolic acid helps individuals achieve a modest amount of weight loss. Additionally, use of lineolic acid is associated with increasing risks for developing heart disease and diabetes.
Research studying the effectiveness of linoleic acid in humans differ significantly from those done in animals. In a human study of linoleic acid reported by WebMD, overweight women lost 9 percent of total body fat over the course of one year. The weight loss occurred without making additional changes in lifestyle or diet.
In contrast, studies of linoleic acid in mice showed that mice experienced a very rapid drop in total body, but began accumulating fat in their livers. Increased fat in the liver is associated with increased risk of insulin resistance and diabetes.
