There is inadequate evidence that flaxseed oil works as a weight loss aid as of 2015, according to Mayo Clinic. However, some studies indicate that flaxseed oil increases fullness while reducing hunger.
Flaxseed oil, or linseed oil, is a source rich with acid alpha-linolenic, or ALA, notes Mayo Clinic. ALA is an essential fatty that changes to omega-3 fatty acids when absorbed by the body. Flaxseed oil contains properties that possibly link to lower cholesterol, as well.
A 2015 study suggests that although flaxseed oil in very high amounts reduces triglyceridemia, it is not as effective as fish oils and vegetable oils, reports the National Center for Biotechnology Information. However, the study also concludes that flaxseed plays a significant role in the strategy of weight loss since it reduces inflammation markers associated with obesity when added to a weight loss diet.
