Once again, McDonald's making things more complicated than they need to be. Most people don't associate fast food with diet food (logical), but in the 1990's, McDonald's tried to make the McLean Deluxe happen. A burger with all the fixings and still 91% fat free? How could it be? They made a burger with lean ground beef and injected it with water and seaweed extract to replace the fat. That had to be mmm mmm GROSS!
