I have this friend who is always exercising and carefully watching what she eats.  She won’t even go into a McDonald’s, because she says its just not the right environment for what she’s trying to do.  So restrictive!

Yeah, she’s fit, superficially.  But it’s not true fitness.  It’s naive fitness.  It’s sheltered fitness.  True fitness is when you stop living in some “exercise and nutrition” bubble and you go pork out on your couch in the real world.
