“Supersize Me” Vindicated in Scientific Study

"Swedish researchers have attempted to demonstrate the scientific validity of the findings demonstrated by Morgan Spurlock in his hit documentary, “Supersize Me.” Eating fast food for just one week led to pathological elevations of alanine aminotransferase (ALT), a common liver test.

"In a study published in the gastroenterology journal Gut, Swedish researchers reported the results of 18 healthy adults, who ate two or more fast food meals a day and limited their daily exercise to walking less than 5000 steps a day compared to a control group whocontinued eating their normal diet and exercise.

"The group that ate fast food gained in average of 14 pounds over the four weeks of the study. Elevations in the liver test ALT were seen in half of this group beginning at the end of the first week and persisted to the end of the study."
