By the end of the study, results showed that the number of calories used during the screening increased by a third.
Films that were deemed to have the most "jump-scares" were seen as the most likely to burn calories as they are actually provoking a physical reaction and accelerating a heartbeat.
Physiologist, Dr Richard Mackenzie, who carried out the test is quoted as saying: "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."
Participants were invited to watch 10 select horror movies to see which was the most effective calorie burner.
Stanley Kubrick's 1980 nerve shredder The Shining came out on top with 184 calories burned on average during its whopping 2-hour 26-minute run time.
Imagine what it would be like if you watched the film whilst on Danny's tricycle. A terrifying prospect.
The top 10 calorie burning horror films were as follows:
The Shining - 184 calories
Jaws - 161 calories
The Exorcist - 158 calories
Alien - 152 calories
Saw - 133 calories
A Nightmare on Elm Street - 118 calories
Paranormal Activity - 111 calories
The Blair Witch Project - 105 calories
The Texas Chainsaw Massacre - 107 calories
[REC] - 101 calories
Terrifying and good for your health.
