Great News.This Halloween we can  watch scarey movies and dump calories at the same time. That according to a new study by researchers at University of Westminster in the U.K. Subjects watched a variety of horror flicks while measurements were taken of their heart rate, oxygen intake, carbon dioxide output and calories burned.

“It is this release of fast-acting adrenaline, brought on by fear, which is known to lower the appetite, increase the basal metabolic rate and ultimately burn a higher level of calories,” Mackenzie said.

According to The Daily, “The Shining” topped the list of the top 10 movies to get your adrenaline pumping, which is what burns calories, cell metabolism specialist Richard Mackenzie told the Telegraph. “Jaws” came in second, and “The Exorcist” was third.

Calories You Can Loose:
