Dear Alice,
For a few months now, I've been hungry all the time. I mean all the time — in the morning, at night, while eating, and even after a big meal. I snack all the time but it doesn't seem to change much. I exercise regularly (but not excessively) and try to eat healthy and I don't seem to have gained much weight. I try to fill myself up with healthy snacks like fruit and nuts. I'm a vegetarian, so I do wonder if the constant hunger could indicate that I'm not getting enough protein, but I haven't eaten meat in years and this feeling only started a few months ago. I know nuts are supposed to be good for you, but I lately I've been eating three or four servings a day, which is quite a bit for a 108 pound woman. (And I'm 22, so I'm not still growing.) Do you know what this could be? Is it possible I have some sort of intestinal parasite? Or is it nothing to worry about? Thanks so much.
