I have overeaten today! Paranoid, help!?

Not that drastically but in a day slight change about 4-8lbs and be the same for 1-3 days but do not worry keep up with your diet and exercise it will get back to the same.. I do it atleast 2-3times a month but after increasing slightly it comes back to normal(even at those times i over eat madly). So don't worry be happy.
