Host: What are the most common hunger signals? Jeannette Bessinger: Some of the most common hunger signals include a graveling. The graveling needs to be above the belt line to indicate hunger. If it's below the belt line then it's probably just your digestion happening. Some people tend to just have a sense of feeling a little hollow or empty in that area around their solar plexus. Other people might feel a little light headed, maybe a little lower on energy but everybody experiences hunger in a slightly different way.
