Calorie Counting

I do try to watch what I eat.  I even downloaded (and used for a month or so), an App that keeps track of the calories I eat and the calories I burn.

But today, while walking with a friend, I "ate" a fuzzy piece of pollen and a gnat.

So what is that?  Like a carb and a protein?  I'm not really sure.  But I do know that perhaps I should talk less while walking in these conditions.
