Here’s some good news as we start the seasonal eating and drinking for this year. To paraphrase a famous saying reports of your holiday weight gain have been greatly exaggerated. In surveys, people say they gain on average, about five pounds this time of year. In the U.S., there are reports pegging the average weight gain at 7 to 10 pounds. So here’s the skinny on this subject from no less an authority than the New england Journal of Medicine: the average winter holiday weight gain..is just one pound. It’s not all good news – most people don’t ever lose that pound of weight, and it certainly adds up over the years. It means that much of midlife weight gain can be explained by holiday overeating. So consider this: a single pound is easily to lose if you tackle it right away.
