"It is now common knowledge that the average American gains 7 pounds between Thanksgiving and New Year's Day"

This quote by Marilu Henner is describing the truth that it is extensively understood that the average American gains seven pounds during the holiday season. This is likely due to the abundance of food and drinks that are typically taken in during this time of year. The vacations are a time for event and extravagance, and it is easy to overindulge in food and beverages. Furthermore, many people are less active throughout the holidays due to cooler weather and the absence of inspiration to workout. All of these aspects can add to the average American getting 7 pounds in between Thanksgiving and New Year's Day. It is very important to be conscious of what you are drinking and eat throughout the holidays and to remain active in order to prevent gaining too much weight.
