The paleo diet, as it’s often called, is becoming increasingly popular throughout the world. In the past few decades, it has gained a notorious following, known for the mantra how we should eat like our ancestors have eaten in the past. At the same time, a steady flow of people has argued that the paleo is unfeasible, mostly because we don’t know what exactly even was on their food plate. In this article I explore some of these notions.

Everybody has a different attitude towards food. Some experience (extreme) pleasure when they’re presented with particularly appetizing food, while others couldn’t care less. This reaction towards appetizing food, together with a personality trait called impulsivity, are two factors with (probably) huge implications in the obesity crisis.
