Supplementing a very low calorie diet (VLCD) with long-chain n-3 polyunsaturated fatty acids (n-3 PUFA) significantly enhances weight loss and BMI reduction in severely obese women compared to VLCD alone.

If you are following a strict, low-calorie diet for obesity, adding a high-quality fish oil supplement (providing roughly 2.8g of EPA/DHA daily) may help you lose weight and body fat faster than dieting alone. This works by boosting your body's fat-burning (ketosis) and reducing fat storage signals.
