The average American will consume about 4,500 calories on Thanksgiving Day when the pre-meal party, the actual dinner and dessert, then evening leftovers are all taken into account. That is enough to gain a pound or two alone, which can be remedied, but how many more days like this will there be?
Actually, there is the potential for quite a few as the holidays approach: Thanksgiving weekend, family holiday parties, work holiday parties, neighborhood/church holiday parties, Christmas Eve, Christmas Day, Christmas week, New Year's Eve and New Year's Day. In addition to extra meals and calories is the fact that activity levels generally taper off during the holidays. The combination of overeating and not much exercise has the potential to provide weight gain that is often not lost, and year after year, a few more pounds continue to be added to the tally.
