The biggest problem with "blowing it" is that very often people just blow the rest of the day, too.

If you recognize that the body doesn't work on a 24 hour cycle, then you can accept that you haven't blown the whole day, but just the last meal. The quality and quantity of your next meal is just as important.

You could compensate for a bad meal by altering the next meal, but only to a point. At some point, the excess cals, carbs, fat, etc. are no longer actively causing their "damage."

While eating a slightly smaller meal after the bad one might help a bit, the 2nd or 3rd meal after that probably won't do anything to compensate, as your system has processes most of the nutrients of that bad meal by then.
