So the left arm is pressed up by the rolls of fat and the fat is probably spilling over onto the door handle so it is obstructing the ability to open the door.  It's right arm has been moved so far over from fat displacement AND it can't reachange with the right hand to open the door. I imagine it is also too fat to reach the controls to recline the seat, and if it could, it would be too fat to sit back up again.
