                                According to the Cleveland Clinic, a sudden, unexplained loss of appetite can be a sign that something is wrong, and it is usually a sign for concern if it lasts for longer than a week. If you've been asking yourself, "Why am I suddenly eating less than usual?", it's a valid concern that can be influenced by a variety of factors, both physical and psychological.
