I wonder if people ever stop to ask themselves why junk food is so cheap. Whenever I would see a sign for saying burgers for 1 dollar at Burger King, it raises a lot of red flags. Don't think their meat comes from happy family farms, they come from industrial factory farming where standards are low and animal cruelty is high.
On a lark, I googled nutritional information about junk food and found out that on average, a typical meal of a soda, fries and a cheeseburger is about 1700 calories - that's a day's worth of calories for an average woman!
Hardee's bacon cheeseburger, for example, just the burger alone, is 1500 calories.
Taco Bell has one of the worst reputations as far as quality of their food goes.
