A Super-Sized Problem

"The extra fat is the big enchilada here, the equivalent of about three sticks of butter daily," Ayoob said. "The liver is basically using its compensatory mechanism to accommodate all this extra stuff."
The liver processes fats in the blood. Excessive calories and fats overload the organ, causing fat to build up in the liver cells and leading to liver damage.
The study echoes another experiment that received both attention and an Academy Award nomination. In the 2004 documentary Super Size Me, filmmaker Morgan Spurlock followed a strict fast food diet for 30 days, eating only items from McDonald's. He consumed an average of 5,000 calories each day, equivalent to about nine hamburgers, and gained 24.5 pounds.
This doesn’t seem to stop major fast food giants from crating more and more extravagant “fatty” burgers to the public. The national obesity ratio is not a problem for them, its all about dollars and cents.
