Fish Oil May Help Burn FatĄ But Not THAT Much Fat!

The biologically active ingredients that seem to make fatty fish so beneficial are are the long chain omega-3 (n-3) fatty acids, EPA and DHA. At least a half a dozen human studies and more than two dozen animal studies have been completed in the last 10 years which suggest that these omega-3 fatty acids found in fish may help you lose more fat. However, the fat loss benefit is not as much as some people want you to believe…
The results of two new studies on fish oil and fat loss were just released earlier this year. In one study published by the International Journal of Obesity, researchers from Reykjavik Iceland tested the effects of fish or fish oil consumption equivalent to 1.5 grams of combined EPA/DHA on body weight and body composition as part of a calorie restricted diet.

The subjects were 324 young overweight men and women who followed one of four experimental protocols for 8 weeks:
(1) sunflower oil capsules (control) (2) lean fish (3) fatty fish (salmon) (4) fish oil capsules
The researchers reported the following results:
"In young, overweight men, the inclusion of either lean or fatty fish, or fish oil as part of a hypoenergetic diet resulted in 1 kilogram more weight loss after 4 weeks than a similar diet without seafood or supplement of marine origin. The addition of seafood to a nutritionally balanced energy-restricted diet may boost weight loss."
It should be noted that the study was supported by the Seafood Plus organization and there were some limitations in the design that could have influenced the subject's compliance.
The second study, conducted at the University of South Australia and published in the American Journal of Clinical Nutrition (2) investigated the effect of combining fish oil supplements with regular aerobic exercise.
In a 12 week placebo-controlled study, the subjects were divided into four groups:
(1) sunflower oil (2) sunflower oil plus exercise (3) fish oil (4) fish oil plus exercise.
The fish oil groups were given 6 grams of high DHA fish oil per day, which contained a total of 1.9 grams of long chain omega-3 fatty acids. The exercising groups performed aerobic exercise three days per week for 45 minutes.
As you might expect, the fish oil plus exercise group came out with the best results:
• minus 1.2% body fat (compared to no decrease in the other groups) • minus 2 kilograms/4.4 lbs (compared to no decrease in the non exercise group).
