Researchers found it takes much longer to lose added holiday weight than to gain it! Studies done in three prosperous countries found Americans gained an average of 0.4% over the Christmas holidays, Germans 0.6%, and the Japanese 0.5%. Over Thanksgiving, Americans put on an additional 0.2%. Actually, Americans continue to gain weight until May, then get slimmer until late October–then start gaining again.
