Popping fish oil capsules will not accelerate weight loss in obese people who are already dieting and exercising, suggests a study published in the American Journal of Clinical Nutrition.
Scientists found that at a diet and exercise program, obese adults who were given omega-3 fatty acids did not lose more weight than those given placebo capsules. To investigate this the researchers randomly picked up 128 obese men and women to take 5 fish oil capsules (i.e. 3grams of omega-3 fatty acids) or 5 placebo capsules every day for 24 weeks. Participants were also asked to do aerobic exercises for 150 minutes a week and strength exercises for about 20 -30 minutes twice a week.
AdvertisementThe people who took fish oil capsules lost 5.2 kilograms (11.5 pounds), while those who took the placebo capsules lost 5.8 kilograms (13 pounds). This was not a statistically significant difference. There was no difference between both the groups in measures of heart disease risk, like blood pressure and cholesterol levels. However, researchers have stated that the omega-3 blood levels in the fish oil group increased to a level that has positive cardiovascular effects.
