Can vampires help you lose weight?

While it’s true that having blood taken from your body does literally make you lighter, watching movies about vampires burns calories. The heart rate and metabolic rate increase during scary movies, leading to an increase in calorie expenditure. Movies with jump scares are the most effective. In a test with 10 horror films (this study was done in 2012), The Shining was the best weight-reducer, burning 184 calories.
