You may have heard from Weight Watchers that the average American gains around 7-10 pounds between Thanksgiving and New Year's Day. However, A recent study by researchers at the National Institute of Child Health and Human Development (NICHD) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) suggests that Americans probably gain about a pound during the winter holiday season-but this extra weight accumulates through the years and may be a major contributor to obesity later in life. The results of their study appear in the March 23, 2010 issue of the New England Journal of Medicine.
Jack A. Yanovski, M.D., Ph.D., the study's principal investigator and head of NICHD's Unit on Growth and Obesity says the good news is that people don't gain as much weight as we thought during the holidays. The bad news is that weight gained over the winter holidays isn't lost during the rest of the year."Sources: http://www.nichd.nih.gov/news/releases/holidayweightgain.cfm
