The real Paleo diet was heavy on plants with very little meat, according to a study of early human remains

• For some prehistoric humans in the Andes, the Paleo diet meant eating lots of plants
• The diet of was likely made up of 80% plants, a study found. 
• There were as many types of Paleo diets as there were human populations back then, an expert said.

The popular Paleo diet is based on the belief that we are better off eating like our ancestors by sticking to a largely meat-heavy diet.

But a new study suggests that some of our ancestors didn't gorge on meat at all, but preferred a diet that was largely made up of plants.
