Omega-3 fatty acids may facilitate weight loss. They do so by

  • Modulating metabolism of fats by stimulating lipolysis or breakdown of stored fat.
  • Increasing production of leptin, an appetite-controlling hormone that also has an important fat-burning role.
  • Decreasing lipogenic enzymes that check storage of fat in the body.

By helping regulate blood sugar levels in the body, a diet rich in omega-3 fatty acids can help keep hunger in check, thus aiding weight loss. In overweight and obese volunteers, there were fewer hunger sensations in the omega-3 fatty acid group immediately after the test dinner and after 120 minutes. Combining fish-oil supplements with regular aerobic exercise improves body composition by reducing body fat. In a study, 66% of young European overweight adults consumed less than the generally the recommended intake of fish.
