The weeks between Thanksgiving and New Year’s Eve have a cumulative effect on weight gain. The weight gained during this time may have long-term effects on obesity. Promoting and maintaining weight stability during the fall and winter months may prove useful as a strategy to prevent unwanted future weight gains. The cause of the weight gain is inactivity and over-eating, and often a “holiday” depression that may occur during this time of year are also factors in weight gain. Americans probably gain about a pound during the winter holiday season, but this extra weight accumulates through the years and may contribute to obesity later in life. Over all, healthy living should be practiced year round to avoid disease and death.
