The most important thing you can do is to stick with sensible portion sizes

Depending on age, weight, and gender, most people should have somewhere between 1,600 and 2,800 calories daily. So at around 1,800 calories in our Thanksgiving dinner, even the CR spread has more than a daily allotment of calories for many.  

Still, it’s not a good idea to skip breakfast (and lunch if you’re having a late celebration) to bank some calories.
