While the holidays may seem synonymous with over-indulgence, research suggests that the average American actually gains only one to two pounds over the holidays. Before you run back to the buffet table, consider this though: While the holidays will come and go, those one to two pounds are often here to stay.
“Really it’s about portion control,” Keri Gans, M.S., R.D., a nutrition spokesperson and author of The Small Change Diet told The Huffington Post. “It’s very important not to use the holidays as an excuse to overeat. And if you do overeat, it’s important that people realize to get back on track immediately: no leftovers, no repeat performances.”
