Fish oil may or may not help you with weight management, or more specifically, fat management. Several factors come into play, some of which can enhance the positive effects of fish oil and others of which can undermine them.
Many studies have explored the effects of fish oil weight loss. However, comparatively few have contended with factors that can influence the results, either positively or negatively. If you search for studies on fish oil vs. weight loss on our national medical database, PubMed, you will find studies that show seemingly contradictory results.
In examining one study that compares fish oil vs. sunflower oil, from a 2007 article in the American Journal of Clinical Nutrition, we can see why results can vary. This and other such comparative reports point out the positive effects of omega-3 fatty acids in fish oil as well as the negative effects of omega-6 fatty acids in sunflower oil.
Additionally, this study looked at the effects of exercise in combination with fish oil. Moderate exercise 3 days per week, such as walking for 45 minutes at three-quarters of the age-predicted maximal heart rate, is all it take for boosting the benefits of fish oil. In contrast, such benefits are insignificant without exercise.
After taking into account all the seemingly contradictory results of multiple studies regarding the effects of fish oil on weight loss, we can consistently see four take-home lessons:
1) The overabundance of omega-6 fatty acids from vegetable oils negates the benefits of omega-3 fatty acids from fish oil. Our modern dietary intake of omega-6 and omega-3 fatty acids is in a ratio of about 20:1. It should be closer to 2:1. Consume less vegetable oil and more fish oil.
2) The benefits of dietary fish oil for fat loss and lean body mass are boosted by even moderate exercise. Such benefits are insignificant in the absence of exercise.
3) The benefits of dietary fish oil are also undermined by sugar. In particulary, fructose and its widespread addition to foods and beverages as high fructose corn syrup cancel out the positive effects of fish oil.
4) The daily amount of fish oil is crucial. It should be at least 1.5 grams, with 2-3 grams being even better. It is also important to take fish oil supplements that have the highest amounts of EPA and DHA, which are the two main omega-3 fatty acids in fish oil.
