Is Metabolism of Stored Fats Better With Low Carbohydrate Diet?

Published:January 24th, 2011

It is a very popular belief that consuming a low carbohydrate diet can result in a slow, more stable increases in the glucose level in the blood.  Furthermore, according to this common idea, a low carbohydrate diet favors the faster and more efficient metabolism of stored fats within the body.

However, in a very recent study published by the January 2011 issue of the Nutrition Journal, it has been shown that a low carbohydrate diet does not have any positive effect to rate of fat metabolism after extensive exercise.

In this study fifteen female cyclist with a BMI range of 21 to 23 were recruited to participate. All their meals were given within the laboratory.  Their insulin levels, blood glucose levels and free fatty acid levels were measured before the observation period. Ninety minutes after their breakfast, they were allowed to have extensive physical activity.  After which, the said laboratory parameters were then again taken. And what did the scientists discover in this study? The researchers of this study found that consumption of a low carbohydrate diet before an extensive physical exertion results in slower metabolism of fats and higher metabolism of glucose compared to the high glucose diet.

The implication of this study: The famous theory that states that a low glycemic meal which is low in carbohydrate content can increase the metabolism of fat is nothing but a marketing strategy. There is no such thing as “converting your body into a fat burning machine”. Want to really burn more fats? Get up and exercise while decreasing your overall caloric intake! This is still the best way to combat overweight and obesity.
