The researchers hypothesise that when this response is triggered the body starts burning fat stores for energy while also releasing blood sugar. It also forces your body to increase your metabolism, which helps your body burn sugar without the need for oxygen. The result is more calories burnt, and your mood is markedly better.
Dr Richard Mackenzie, a metabolism specialist at the University of Westminster, told the Daily Mail “It is the release of fast-acting adrenaline, produced during short bursts of intense stress, or in this case, fear, which is known to lower the appetite, increase the basal metabolic rate and ultimately burn a higher level of calories."
The scarier the movie is, the more calories you’ll burn, and researchers surmise that you’ll burn the same amount of calories watching a horror film as you would on a 30 minute walk.
