I use a 6-pack size cooler bag. Inside it, I pack whatever I can find in the kitchen, like an unhinged raccoon foraging the trash. Maybe something normal like a sandwich. More commonly, like half a green pepper, leftover corn chip crumbs, and a tablespoon of cream cheese, or some such. Then I open the lunch bag and wonder who packed my lunch.

Me too. I was doing a version of this where I would distance myself from my physical body and view it as separate/other in order to objectively care for nutrition, exercise, etc. needs when unmotivated. But this seems even better because it allows for distancing from the mental needs too. The tiger! Obviously!
