In a recent interview, Luke Combs opened up about his lifelong battle with his weight and how he wants to get in shape so he can be there for his newborn son. Luke knows what he needs to do in order to slim down, but he has a hard time staying consistent. He feels like food is an addiction for him. "Food is the only drug that you are addicted to that you have to have to live," says Luke. "I don't need to have a cigarette to be alive, but I need food to be alive." Luke wants to make sure that he's around for his son for as long as possible.
