SWALLOWING fish oil as part of
an exercise regime helps shed kilograms faster, new research
shows….
An Adelaide study has found that overweight people on a modest
exercise plan lose more weight if they also take daily doses
of tuna oil rich in Omega 3 fatty acids.
The polyunsaturated fats, found in oily fish and some grains,
nuts and vegetables, have cardiovascular benefits but little
is known about their contribution to weight loss.
The University of South Australia study involved overweight
or obese people with cardiovascular problems like high blood
pressure or high cholesterol.
Participants did not alter their diet but took regular doses
of either tuna fish oil or sunflower oil, which does not contain
Omega 3.
After three months of light exercise - a 45-minute walk or
run three times a week - those consuming fish oil had lost
an average of 2kg.
Those who took sunflower oil, as well as other groups who
took either oil without exercising, lost no weight at all.
"We were very surprised to see it was so effective, especially
since these people were still eating whatever they wanted,"
said researcher Alison Hill.
"It's pretty exciting because this implies the results
would be even better if you did control diet and exercised
more heavily."
Scientists are still unsure exactly how Omega 3 works but
they believe it may improve a person's ability to burn fat.
"We suspect that they improve blood flow to exercising
muscles and stimulate key enzymes to transport fat that needs
to be used as fuel," Ms Hill said.
"In overweight people this ability is almost always impaired."
