Get your family together and have each person share the most important part of the celebration then create your Holiday using this information. When your Holiday celebration is in alignment with your priorities then you feel satisfied and have little need to fill yourself up with extra food or drink. Yes there are lots of wonderful foods that we make and share during Holiday celebrations. Family recipes, new dishes and lots of wonderful treats. Practice moderation rather than restriction.
Restriction leads to focused attention on food and weight gain.
If you indulge in a rich dessert then go for an evening walk or skiing for the afternoon. Identify habits, triggers and alternatives. Holidays trigger memories and old habits. Many times these memories might trigger you to eat more than your body desires because you are using food to re-connect with the memory. The habits might be around excess with food or drink.
