The study - which was conducted by researchers at the University of Westminster - found that a 90-minute horror film can burn up to 113 calories ... which is the equivalent of a 30-minute walk!

The researchers monitored participants heart rate, oxygen intake and carbon dioxide output while watching a scary movie.

Dr Richard Mackenzie from the university said: "Each of the 10 films tested set pulses racing, sparking an increase in the heart rate of the case studies."

"As the pulse quickens and blood pumps around the body faster, the body experiences a surge in adrenaline."

"It is this release of fast-acting adrenaline, produced during short bursts of intense stress (or in this case, brought on by fear), which is known to lower the appetite, increase the basal metabolic rate and ultimately burn a higher level of calories."

These are top 10 scary movies for weight loss:

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
