Ezra Klein has a nice column on how you might keep yourself from overeating this Thanksgiving.  I cannot actually recommend my current strategy, which is to get bilateral un-crowned root canals¹, so that you have to spend the next three weeks eating only foods which are squishy.  But it does seem to be working.

¹Before you start in with the inevitable aspersions on my oral hygeine, they resulted from two prior fillings which shrank away from the tooth, letting bacteria underneath. After all my teeth are repaired, I am going to track down the dentist who did both fillings and give him a sound lashing with my portable waterpik.
