Never go to a party starving. Always have a healthy snack before (almonds are a great choice). When munching on appetizers make choices that will fill you up. Focus on foods that will provide you with fuel. Protein rich foods are great choices, some examples are thinly sliced turkey, shrimp cocktail and other fish or poultry. If you just want to munch, go for some veggies. Cheese is another good protein source, just in moderation. It is all about balance: choose a couple of treats that look appealing but save room for dinner later on. Do not just fill up on appetizers and think you will not be hungry for a real meal in a couple of hours. Be aware of how hungry you really are and mindful of your choices. Have a plan, be social, have fun and enjoy yourself!
