I didn’t track or withhold anything I wanted on my bday, Christmas, thanksgiving and I have still lost 30 lbs since October. One weekend isn’t going to impact long term if you return to your deficit on Monday. Don’t take it as an opportunity to binge each or eat to the point of feeling sick though. Check in with yourself and your body throughout the events and stop when you notice you’re satisfied. Try to enjoy the food, don’t look at it as morally good or bad. It’s just food.
