If you’d like to lose weight – try scaring it away.

Did you know you can burn calories just by watching a scary movie? 

It’s true. A new study by the University of Westminster says the average burn of terror is about 113 calories. It needs to be a really scary movie to work, inducing increased heart rate, oxygen intake and a few moments that make you jump or wince. The researchers even went so far as to list the top 10 frightening films and their calorie burns:

1. The Shining: 184 calories

2. Jaws: 161 calories

3. The Exorcist: 158 calories

4. Alien: 152 calories
