Drumroll, that makes sense. My brain often processes things in images. If I think of carbs, my brain thinks "dust" - easy to digest, fat would be "squishy like jello" - a little harder, and protein makes me think of a lean raw steak - the toughest of all. Also, somewhere in my past I learned that protein molecules were long complex chains - which would be tough to break down.
Anyway, somewhere in my youth I decided I would rather look like steak than dust or jello, and started eating lots of protein. It's hard to kick those images when they've been in one's head for so long and they seem to work. That probably sounds crazy.
