Answer in the comments, since I don't have enough readers to bother with a poll widget.
Which is more difficult to do if there is a plate of French fries within your reach?
A. eat zero -- don't even touch them
B. eat one or two, and then stop
(If you don't love French fries, please substitute any other item that you love that comes in small bite-sized quanta, e.g., jelly beans, chips with salsa, etc.)
