Cap'n, I'm thinking the idea is to counter any extra stored fat due to the cheat meal.
Compared to a drive or plunking your ass on the couch it will burn perhaps 200 kcal there and back if it's, say, a half hour walk. Heck, the after meal walk may even help lower blood sugar levels.
All you have to do is burn off the extra calories you would store not the whole thing. Would 300-500 calories do the job? Maybe.
