Fish oil may not help you lose weight faster if you’re already dieting and exercising.
A study in the American Journal of Clinical Nutrition divided overweight and obese adults already enrolled in a diet and exercise program into two groups: those taking fish oil and those taking placebos. The study found that after 24 weeks, those who took Omega-3 fatty acids didn’t lose anymore pounds than those given placebos.
Researchers did note an increase in Omega-3 in the blood levels for those taking the fish oil pills. Fish oil does many health benefits: cutting cholesterol, improving insulin sensitivity and reducing blood pressure.
