How to Stick to Your Diet During the Holidays:
Be careful of leftovers. Don't eat a lot of calorie-laden food for days after a special event just because the food needs to be eaten up. Portion all leftovers in small amounts and ensure that everyone is sharing it, so that you're not tempted to finish off the remaining half of a cheesecake by yourself.
Never use the excuse "it'll go to waste if I don't eat it." That is why you have a freezer, friends and family over for "leftover surprise meals" and a compost bin. Bundle up leftovers for freezing––ham, turkey, pudding and other items can all be frozen without damage.
