Why do we gain weight in winter?
为什么我们冬天会长胖?
For many people, winter holidays provide perfect chances to enjoy themselves. This can certainly make it easy to put on weight. "Holiday weight gain isn't all from celebrating," says Christina Badaracco, a dietitian(营养学家).
Some animals like to eat more to keep warm in cold weather when food historically was more valuable(宝贵的). We human beings are just like them in this way. Plenty of fresh fruit and vegetables aren't in season at this time of the year, leading us to eat richer foods.
"In winter, we get less sunlight and stay inside more," says Badaracco. This can influence metabolism(新陈代谢), which plays a role in holiday weight gain.
People are less active during the winter months, and their interest in getting outside to exercise or even driving to the gym. More than one - third of Americans reported sleeping more in winter.
Besides, when the temperature drops and daylight hours reduce, we feel especially cold. Therefore, many people like to find comfort in drinks.
According to a survey, people expected to gain 5.5 pounds over the winter holidays, but research suggests that in fact, most people gained only around 1.5 pounds. "People always think that they will gain more weight over the holidays than they actually do, but the weight they gain over the holidays will increase over time if they don't lose it," Badaracco says.
It is completely normal to have weight changes throughout the year. The key is that you intervene early if it continues growing over time. You can make an exercise plan, weigh yourself daily or find a friend to keep you company. "It's more important and useful to set small, slow and manageable goals. Then you can aim higher through small wins," says Badaracco.
