When I feel like torturing myself, I multiply servings x
   calories-per-serving. I'll do the same for carbs or fat or
   sodium. Totally ineffective though. I know the numbers, and
   still eat the whole bag.

   I excuse myself by multiplying the protein as well. Protein=good
   therefore the rest doesn't matter. *sigh* anything is
   justifiable.. especially when you get some statistics involved
