It kind of depends on how much you exceed it by, no?
Lets say you eat 300 extra calories on 2 days.. that's 600 / 7 days, which is 85 calories a day extra. To lose a lb, you need to be 500 calories under your BMR daily, so you would now be 415 under, and still lose weight. You may temporarily gain, but over time, you will still be losing about .83 lbs a week, instead of 1 lb a week.
If you eat 3500 more a week, you wont lose anything. You can do that in a single binge. Try to make any cheats as small as possible, and as few as possible. Most importantly don't get depressed over 300 extra calories, and eat a pint of Ben & Jerry's..lol
