Hi there. Sorry to hear about your friend. Weight loss like that can happen even when they are eating properly (or what is proper to you and me). With cirrhosis, his liver is not functioning good anymore. It's not doing it's job anymore. He needs a special diet to help prevent the weight loss and to get the vitamins he needs now. There are very special diets for people with cirrhosis that can help. If he's not under the care of a liver doc or not on a special diet, I would try to get him to go see a doctor as soon as possible and see if the doc can help. There are possibly many things a doctor can do to help him at this point.
Best of luck.
