KFC and any fast food chain is gross.
I recently lost A LOT of weight (about 6 dress sizes) due to cutting that crap out of my diet. I also, have another reason now not to eat anything fast food. I watched a show on National Geographic, 6 degrees that could change the world...some guy did a study, on fast food...he found eating 3 burgers a week is worse than driving an SUV your whole life.
He included the methane gas the cows produce, the fuel used to transport it, and the energy that is used to store and cook it.
Fast food isn't just giving people weight and heart problems, it is also helping to pollute the planet. Not to mention how lazy it makes people. Less than half the people I know can cook a damn meal for themselves. Why learn to cook when you can order pizza or drive to McDonald's.
