Loosing Weight Before The Shut Down

I has another big eating day yesterday specially at the party. What do you expect on the weekend, specially when at the party. But that's okey, I will make sure to eat less this week and make sure to lose weight before the end of the year.
We are going to have about 2 weeks company shut down so I want to make sure that I will lose weight before the shut down starts. Otherwise, weight and fats will add up before the end of 2 weeks. I don't want to be fat anymore.
