In a group of adults obese and overweight who follow a diet and exercise program, those who took omega-3 fatty acids do not lose weight, than those given a placebo capsule, according to the invention researcher Laura F. DeFina of the Cooper Institute in Dallas and colleagues.
Indeed there is evidence from animal studies that omega 3 can help weight loss, according to the DeFina. However, studies in humans show a variety of results.
Fish oils have potential health benefits, including lowering cholesterol, improve insulin sensitivity and reduce blood tekanana. "Thus, weight-loss program that is identical with the consumption of omega-3 polyunsaturated fats such as sound right," write the researchers in their report. But that assumption is not always evident.
To investigate whether fish oil is to strengthen the person's diet and exercise, researchers randomly asked 128 male and female obese or overweight with no active lifestyle, to consume five capsules of fish oil - equivalent to three grams of omega three - or five placebo capsules daily for 24 weeks.
Participants were also instructed to perform aerobic exercise per week for 150 minutes They were also asked to practice the strength and stamina of 20 to 30 minutes each practice on every week.
Omega-3 group with weight loss up to 5.2 kilograms. While the group who consumed the placebo experienced shrinkage weight 5.8 pounds. That number did not show statistically significant differences, meaning people in both groups lost more than 5 percent body weight, and enough to get health benefits.
Only, in the first group contained elevated levels of omega-3 levels in the blood - which according to the study proved - have an impact on heart disorders.
