If it seems that others want you to eat more, or they say that they think you look too thin, it probably means that they care about you. They may want to see you in a healthier place.
This doesn't always signal an eating disorder, of course. Grandmothers are famous for saying that their grandchildren should eat because they look too thin. But if people who are very close to you are saying that you don't seem to be eating enough, it's probably time to take notice.
