I often tell clients that they can have a 2 lbs allowance for the holidays. It forces them to be mindful and it leads to them actually losing weight over the holidays. Also, understand what a second helping actually means calorie wise and you might think twice. Another big no no is mistaking thirst for hunger. Make it a point to push the water intake. And lastly, remember we are relational beings and people are more important than food. Hard to appreciate them if you're in a food coma.
