Christmas food

This is a great time of the year...I get lots of chocolate, cakes, cookies, etc. and I can eat as much as I want and because its Christmas time, I won't gain weight. Thats true isn't it? But, I figure that I can't gain much weight--all I have eaten so far today are about 13 chocolate truffles, a couple of donuts and a few cookies. I am sure that my lunch will be much healthier.
