Fast food restaurants similar to In & Out Burger, McDonald's, Sonic, etc. with food still inside.
You're telling me that I can eat a can of 200 year old beans and be fine, but I can't eat a burger that has enough fat inside of it to insulate a small home?
It's like drugs. And if you eat too much you become overweight. When you look at your weight it says you weigh 650 pounds.Your strength, endurance, agility, and everything that remotely evolves physical activities are lowered to one. You become too fat to fit in any clothes so you must run around in your underwear. You are permanently over encumbered and must walk, not run anywhere. You cannot fast travel either.
Now if you have the option of putting food into someone's inventory, hurting them with your fists, and then they eat it to fix there HP. Give enough people McDonald's burgers with everything on it, and you will have everyone in the city is overweight. Imagine 20, 650 pound people waddling around in New Vegas.
