How long can you survive, eating yourself

Eine der besten Kurzgeschichten von Stephen King handelt von einem Mann, der mit dem Flugzeug abstürzt und auf einem Felsenhaufen im Meer landet. Um zu überleben muss der Mann sich langsam selbst aufessen. Und jetzt haben ein paar Leute nachgerechnet, wie lange man damit überleben könnte. Yummy!

Firstly, how much raw limb is there to harvest? According to figures collected by NASA for their average 82.5Kg crew member, the arms and legs make up approximately 40% of body mass – in this case, around 32Kg.

To work out how much energy is available from this, we need to use something as a proxy, because little is known about the calorific value of human meat. In this case, we’ll use uncooked pork chops, which, according to a well known high-street supermarket, offer 213 calories per 100g. This means that our 32Kg of limbs could provide an impressive 68,000 calories.
