The research compiles data from thousands of Withings' wireless scales. The data tracked weight gain and loss among adults in the United States, Japan, and Germany starting back in August 2012. Of the participants, 1,800 were from the U.S., while it tracked around 800 from Germany and just under 400 from Japan. While the results varied by country, they tended to show the same kind of increases around holidays.
The fact that participants had the scale, which values at around $150, suggests that the sample is a specific population with the means and desire to track and control their weight. But Professor Wansink argues that this just further proves his point. He contends that this is a population less likely to put on excess weight. "Even among this diligent, almost-ideal population, there’s no escaping this almost inevitable holiday weight gain," he says.
So, congratulations. This is as good as things are going to get. Get ready for a marathon of candy, turkey, stuffing, latkes, eggnog, fruit cake and terribly frustrating political discussions with strange relatives. Oh, and beer.
