Look for some lighter foods to serve and offer these as an option, for example strawberry pavlova or fresh fruit salad as an alternative to Christmas pudding. And choose a light salad based starter too. Look online for hints and tips about reducing the fat content in a typical Christmas lunch. You can reduce the calories by half and still serve up a delicious meal. At the very least remove the skin from turkey and any visible fat from meat and make the gravy ahead of time so that you can skim the fat from the surface when it cools.
