Another thing that test kitchen chefs have discovered is that people will eat more food if they don’t have to work too hard to chew and swallow it. Hence much of the meat served in chain restaurants has been mechanically tenderized and injected with marinade. It dissolves in your mouth quickly and is lubricated for swallowing by high water content. In essence, the factory has done half of your chewing and swallowing for you so you can eat more. And finally, one of the simplest strategies is to take advantage of the fact that people tend to finish what’s on their plate (or drink what’s in their bottle of soda). Bigger portion sizes are a simple and effective way to promote overeating, defeat the body’s appetite control system, and sell more food.
So, basically we’re one brain-stem-probe away from being full participants in The Matrix.
