recent study that was published in the international journal of obesity, researchers want to find out if by supplementing the diet with omega 3 fish oil (good fat) would increase the number of fat calories burned in a single day.
The two groups were fed exactly the same diet apart from one group were fed 6 grams of fat in the form of butter, olive oil, sunflower oil and peanut oil, the other group were given 6 grams of omega 3 fish oil.
The fish oil group were given 8 capsules per day, 2 in the morning, 3 at lunch and 3 in the evening.
The Total daily intake of omega 3 long chain fatty acids was 1.8 grams.
The out come of the test results were fairly conclusive.
The table below shows you the changes in fat oxidation, body fat, and metabolic rate after three weeks for the groups with or without fish oil
|without fish oil||with fish oil|
|Measurement of body fat lost||0.7pounds||-2 pounds|
|Daily metabolic rate||1710 calories||1775 calories|
These results show that the group who were supplementing with fish oil burned about 1.1 milligram of fat per kilo per minute. This is roughly 26% higher than the other group who weren’t supplementing with the fish oil.
One of the key reasons as to why omega 3 fish oil has such a powerful effect on fat metabolism is that the insulin levels were 50% lower when subjects used the fish oil. Insulin is a hormone that reduces the use of fat for fuel, while also promoting fat storage in the presence of excess calories.
Insulin increases the activity of an enzyme known to promote the storage of fat.
Insulin inhibits the action of hormone sensitive lipase, which is responsible for breaking down stored fat and preparing it for use as energy.
Insulin also activates an enzyme, which, along with fatty acid synthesis, is responsible for converting carbohydrate into fat.
Simply put, high levels of insulin make it less likely that your body will use stored fat as a fuel source. The drop in insulin levels when subjects used the fish oil would have allowed more fat to be used for energy.
