If you watch this horror movie, you will lose weight!

Losing calories sitting quietly on the couch while watching a movie is possible! As long as the movie in question is scary enough.

Indeed, according to a very serious study by the University of Westminster (Posted in 2012 by The Telegraph), the anxiety caused by certain fictional horror movies will help burn calories and, therefore, lose weight.

So whether you’re ready to brave a shark in the jaws, Jack Nicholson’s ax in a movie, or a terrifying alien crawling through the corridors of the Nostromo, the adrenaline rush that should come with your session is likely to burn 113 calories. In 90 minutes, the equivalent of half an hour of walking or cycling.

Researchers who conducted the famous study came to this conclusion by observing a panel of viewers and measuring their heart rate, oxygen consumption and carbon dioxide emission rate while watching 10 carefully selected horror movies.

Among these feature films, some are clearly more effective than others in stimulating viewers, and thus The Shining proved to be the most effective, causing its viewers to lose 184 calories.

(If Stanley Kubrick’s film is so radical, it’s largely thanks to them!)

Here are the top 10 according to a British study:

1. Brilliance (184 calories)
2. Jaws (161 calories)
3. The Exorcist (158 calories)
4. Alien (152 calories)
5. saw (133 calories)
6. Freddy: Night Claws (118 calories)
7. Paranormal Activity (111 calories)
8. Texas Chainsaw Massacre (107 calories)
9. The Blair Witch Project (105 calories)
10. (101 calories)

According to Dr. Richard McKenzie, who conducted the study, the process is simple: the heart rate of viewers under the stress of a movie increases. The heart then pumps blood faster and the body experiences a surge of adrenaline, which reduces the subject’s appetite and allows him to burn off more calories.
