A study published in Scientific Reports concludes that eating other people - not that nutritious.
Results show that humans have a comparable nutritional value to those faunal species that match our typical body weight, but significantly lower than a range of fauna often found in association with anthropogenically modified hominin remains.Author of the study stated,
“When you compare us to other animals, we’re not very nutritional at all,” says study author James Cole of the University of BrightonThis means,
... motivations behind hominin anthropophagy may not have been purely nutritionally motivated. It is proposed here that the comparatively low nutritional value of hominin cannibalism episodes support more socially or culturally driven narratives in the interpretation of Palaeolithic cannibalism.Early cannibalism wasn't a health thing, it was a social/cultural practice.
How primitive, cavemen choosing their diets based on weird cultural superstitions. Not like us and our science verified nutrition based diets like the Atkins diet, The Zone Diet, Ketogenic Diet, Vegan Diet, South Beach Diet, Raw Food Diet, Mediterranean Diet, Dukan Diet, Subway Diet, Alkaline Diet, Montignac Diet, Hay Diet, Blood Type Diet (and we're getting really weird now), Tapeworm Diet, and my personal favorite, the Kangatarian Diet, which involved the consumption of what I assume is a whole lot of Kangaroos.
I'm confident some of these diets are great. But take note: when you restrict your diet in any way at all you will find eating a less pleasurable experience and on average you will lose weight.
