Burn Calories Watching Horror Movies [Video]

So we've all heard the expression, that's so scary it will "scare the pants right off you", but have you heard that scary movies can scare the calories right out of your body?  Well, maybe not literally.  According to a new study commissioned by website LOVEFiLM.com, researchers from the University of Westminster in the UK found that people who viewed horror movies for 90 minutes can burn the same amount of calories used up during a half-hour walk.  Or if you want to consume a chocolate bar, watch a horror movie to burn up the amount of calories consumed.   and the equivalent to a chocolate bar. Researchers at England's University of Westminster measured the total energy expenditure of ten different people as they watched a selection of frightening movies. Scientists recorded their heart rate, oxygen intake and carbon dioxide output - and discovered the number of calories used increased by on average a third during the films.

The top 10 calorie-burning frightening films were:

1. The Shining: 184 calories
2. Jaws: 161 calories
3. The Exorcist: 158 calories
4. Alien: 152 calories
5. Saw: 133 calories
6. A Nightmare on Elm Street: 118 calories
7. Paranormal Activity: 111 calories
8. The Blair Witch Project: 105 calories
9. The Texas Chain Saw Massacre: 107 calories
10. [Rec]: 101 calories
