Why are we driven to eat?

Why are humans driven to eat?


This is covered in more detail in the Healthy Planet Project (Try the 14 Day Free Challenge), but I’m going to give you a bit of a teaser here.

Let’s start with the basics.


If you think of any animal…


(I think of a tiger when I’m asked that – can a psychologist tell me what that means please)





Whatever animal you’re thinking of, it requires energy.


Energy to move around, to carry out bodily processes, and ultimately to mate and prolong the survival of its species.


Natural selection therefore rewards effective energy/food-seeking behaviours


The animals that survive are the ones that are best at hunting, foraging, going to where their food is at the right time.


This used to be us.


Hunter-gatherers.


With the ability to fashion weapons and run long distances to track down prey.


Our brains, fundamentally, haven’t changed much since those days.


In some people, this is more obvious than in others…


But on a serious note, our brains still reward us for seeking food effectively and efficiently


Expending as little energy as possible, in order to get as much energy as possible.


Fast forward to the 21st Century, and what do we have?


Food at every turn.


Foods that trigger reward centres in the brain.


Available from a local shop that you can drive to, or even at the touch of a button


Someone will literally deliver thousands of calories straight to your door.


And you haven’t moved further than the distance from the sofa to the front porch.


The hard-wiring in our brains thinks this is brilliant.


And so we want to do it more often.


Get as much energy in as possible, while expending as little energy out as possible.


Is it any wonder that we have an obesity crisis?


Food for thought…
