According to Business Week, U.S. consumers spend $40 billion dollars a year on weight-loss programs and products, and that's a conservative estimate. Despite throwing so much money at the obesity problem, the National Institutes for Health reports that 66% (two out of three) adults in the U.S. are overweight or obese. While Jenny Craig meal plans and Atkins shakes continue to cost dieters a fortune, scientists are working on a much cheaper and more effective solution for weight loss: fish oil.
Compelling Fish Oil Weight Loss Studies
Several new studies into fish oil weight loss are showing promising results. A scientific study in Japan showed that mice fed omega-3 fatty acids and encouraged to exercise had a faster metabolic rate and put on less weight than mice that did not have the same regimen.
In Australia, a scientific study on 75 people who were overweight/obese and had additional risk of heart disease found that taking 600 mg fish oil supplements along with regular exercise led to a loss of 4.5 pounds in the three week period, without any change to the participants' diet. In contrast, those who took sunflower oil supplements (with no omega-3) or those who took omega-3 supplements without exercising saw no change in their weight or fat deposits.
Finally, the University of Georgia reported their findings about fish oil weight loss in the Journal of Nutrition. Their studies showed that fish oil prevented pre-fat cells from becoming fat cells by effectively causing the pre-fat cells to die. This meant that there was less fat stored in the body.
How Fish Oil Weight Loss Works
Gathering together all the information from these studies, it appears that taking fish oil supplements of 600 mg per day acts as a catalyst for the body to increase fat metabolism when exercise is performed. This increase in fat-burning leads to lower fat deposits in the body, specifically belly fat.
If exercise is absent, then the fish oil provides many other health benefits including supporting a healthy cardiovascular system and lowering inflammation, but it does not trigger weight loss in itself.
The Australian study was performed on overweight/obese people who continued with the same eating habits. However, by combining omega-3 fish oil, exercise, and a calorie controlled diet, faster weight loss could be expected than just restricting calories alone.
Tips for Fish Oil Weight Loss Success
- Choose a high quality fish oil supplement that has a high level of DHA and EPA for the best results.
- Check the origin of the fish oil. Alaskan fisheries tend to supply fish with less toxic metals.
- Discuss your fish oil supplementation with your doctor, especially if you are already on medication. Although fish oil is safe, it may counteract other meds.
