I'm no expert (I sometimes give in at these gatherings, too) but here are a few things that have worked for me in the past.
1. Stick to your regular calorie counting for the first part of the day. Be sure to eat a little smaller portions than usual so that you have a few extra calories to "spend" at the get-together.
2. Get in a good workout. Again, this gives you extra calories to "spend" later. It sometimes also gives a person incentive to make better choices later.
3. When you do get to the party, find places where you can save a few calories. Make one choice instead of another. For example, if your favorites are things like the nachos or the potato chips, are you willing to choose something less calorie-laden to drink in order to make up for the extra calories in your favorites? (Did that make sense?)
4. It's hard, but try not to pay too much attention to the foods other people around you are enjoying. Enjoy the game and the people.
Take care and enjoy the day!
