The short answer as described by my friend Ms. Lane: For our intents and purposes, it is that b!tch part of your brain that says "you can't do it - go sit on the couch instead"
The long answer is also from Ms. Lane. See we were on a walk about beautiful Lake Harriet when I started talking to her about how I was dissatisfied with my body image. I was describing how I've slowly realized that I've let myself go. I was no longer confident, let alone healthy. I also told her that I just haven't found a motivating factor to jump start my workouts or healthy eating.
She kind of giggled at me (her giggle makes me giggle, and then we get yelled at for being loud and it's back to the basement for us, but I digress). Then she said, "You're listening to your Lizard Brain too much." I said, "wha?" Then she explained:
See back in the day dinosaurs were so large that they had to have two brains. One controlled the top half of their bodies, and the other one controlled the bottom half. And as dinosaurs evolved they had less and less need for the second brain. Turns out lizards today still have an area near their tail where their old brain used to grow. This is the brain that keeps them down. The Lizard Butt Brain that says, "Meh, you don't need to take care of yourself", or "Dude, don't go for a walk, just sit on the couch", or "Go ahead, eat the whole entire pizza!".
The Lizard Butt Brain, or Lizard Brain, or Lizard, or LB for short, is that part of you that says "You can't". But you CAN! And all you have to do is kick the Lizard Butt Brain to the curb. Go ahead, give it a kick. It feels good!!!
