I agree. Her parents hold at least 97% percent of the blame. However, while I was away at college, my family and I have been regularly pushing her to go running at the gym that is in her apartment complex. She did it for a week and gave up. When she comes over, she sometimes tries to sneak extra food. This is going to be a long process, and I'm really hoping she'll be able to resist the urges to eat large portions.
