1. Eat breakfast - but keep it light. Try fruit, a boiled egg or yogurt.
2. Don't snack. It's a good way to save worthless calories.
3. Eat lunch and dinner as normal to keep your body in a routine, but stick to salads with a protein such as fish, eggs or lean meat.
4. Go for a 45-minute run before you get ready for your party. It will remind you how good it feels to be fit and your complexion will look terrific for the night ahead.
5. You've just eaten 500 calories and burned 500 calories, so you're in the clear for a great night!
