A creepy subject, indeed, but someone has actually calculated what cannibalism would imply: eating a human body would provide about 81,500 calories!
This is according to James Cole, a lecturer on human origins at the University of Brighton, England. Every part that could be consumed should be cooked for the body to yield those 81,500 calories’ worth of food.
Cole’s findings come from his research based on information about body composition published in the 1940s and ’50s.
Even though they might sound like a lot of calories, it’s nothing compared to some animals; for example, a horse’s 200,000 calories.
