After reading a report by a consumer group about the effects of unhealthy food from popular chain restaurants, ABC's Yuji de Nies and Jon Garcia conducted a test to see how eating these foods for lunch would affect their bodies.
Before they ate lunch, Yunji and Jon had blood samples drawn and an ultrasound done to test the health of their arteries. They then sat down to a meal of 6,190 calories and 187 grams of saturated fat -- an appetizer, lunch and dessert from a popular chain restaurant.
To see what happened to their blood and arteries immediately following the meal, watch the clip below.
