Puzzle of the week

Second Law of Blissful Ignorance: Inside every small problem is a large problem struggling to get out.

Here is the puzzle of the week:

There are 5 burglars and once they went to a bakery to rob it (obviously). The first guy ate 1/2 of the total bread and 1/2 of a bread. The second guy ate 1/2 of the remaining and 1/2 of a bread. The third guy, fourth guy and fifth guy did the same. After fifth guy there is no bread left out. Can you tell how many bread were there?

Solutions to this puzzle can be posted as comments. Try for the most optimal solution. I'll also need to try out...

Hope to see an active participation for this... :-)
