The fact is, fish oil has a number of important health benefits. But, the idea that fish oil is some kind of magic bullet for weight loss is nothing more than a myth. You can't just pop a lot of fish oil capsules and expect your fat to melt away without making changes to your diet and exercise program first.
A study published in the American Journal of Clinical Nutrition suggests that daily consumption of fish or fish oil is only effective for weight loss, if it is combined with moderate exercise like walking for 45 minutes three days a week.
This study looked at 75 overweight subjects for a period of six weeks who took fish oil and exercised: subjects who took fish oil and did not exercise, and subjects who took Omega-3 sunflower or flax seed oil and exercised for three days a week, vs those who took the vegetable oils and did not exercise.
The subjects who lost the most weight were in the group who ate moderate amounts of healthy foods, exercised three days a week, and took fish oil.
Are we really surprised?
