I love Christmas - and I love Christmas food.  If you don't want to gain weight over this festive period here is what I aim towards.  Try eating the lean meats and seafood, staying away from the heavy carb loaded potato dishes and do eat the yummy salads.  I will absolutely be having a bit of the desserts...but will probably steer clear of the Christmas pudding and cake's which are filled with dried fruits.  I may go for some gingerbread instead.  I'ts a special occasion so i  will treat myself a little.  Enjoy!
