Fish oil for weight loss?
Wednesday, May 12, 2004 10:05 am Email this article
fish oil reduces body fat and stimulates fat oxidation according to one study.
Five men and one woman with an average age of 23 years and a body mass index (BMI) of 22 ate a non-calorie-restricted diet for three weeks containing 52 percent carbohydrates, 16 percent protein, and 32 percent fat.
Three months later subjects were fed the same diet for another three weeks, however 6 grams of dietary fat was replaced with 6 grams of fish oil. This is the amount of oil found in 4-7 ounces of fish depending on the species.
Fish oil reduced body fat (-1.9 pounds versus -0.7 pounds, respectively) and increased basal fat oxidation twenty percent (1.06 versus 0.87 mg/kg/min), however total calories burned was unchanged.
Fish oil also increased fat-free mass (+0.4 pounds versus -0.5 pounds, respectively), however, the difference was not significant.
Fish oil increased blood sugar (5.0 versus 4.7 mmol/liter), and decreased insulin levels (5.3 versus 10.5 uU/ml).
The fish oil was given as eight capsules of 750 mg each (two capsules at breakfast, three at lunch, and three at dinner).
