(HOLLYWOOD, CALIFORNIA) Watching a scary Halloween movie is healthy. You could lose up to 200 calories. Your heart races, your muscles tense, and you’ll occasionally scream and reach out to grab the one close to you. With a different perspective, you might look at going to the movies as exercise.

Researchers tested the theory against some of the classic fright flicks. The top calorie-burning frightening films:

  • The Shining (184 calories)
  • Jaws (161 calories)
  • The Exorcist (158 calories)
  • Alien (152 calories)
  • Saw (133 calories)
  • Paranormal Activity (111 calories)
  • The Blair Witch Project (105 calories)
