Tired of Blizzard Bloat? Reversing Winter Weight Gain
Have you noticed your weight creeping up this winter? Are you experiencing more cravings than usual, especially for heartier, more fattening foods? Well, take heart. You’re not the only one experiencing “blizzard bloat,” the creeping up of body fat hitting a large number of people during the winter months.
In the animal kingdom, fattening up in winter is critical for survival. Animals overeat to store enough excess fat to survive until spring. The human animal has a similar natural instinct, probably leftover from the days when food was scarce in winter and shivering in the cold caused us to burn our fat stores too quickly, leaving us too thin to survive (aaaah, those were the days!). But now, with temperature control, improved agricultural techniques and a cupcake shop on every corner, that leftover but highly frivolous instinct just causes trouble. Because of modern conveniences, we humans fatten up following the old instincts when we no longer need to!
Though these old instincts are plausible as a cause of winter weight gain, there are more complex—and controllable—causes too. The most important probably involve decreases in both sunlight and physical activity. Together, they can contribute to enough of a calorie imbalance to cause weight gain. Here’s how.
· Sunlight. Some people are particularly susceptible to light deprivation, caused by the decrease in daylight hours during the winter. This affects the neurochemical serotonin, responsible for your mood and appetite, prompting increased food cravings and weight gain.
· Physical Activity.When it’s cold outside, we’re less physically active and cut back on subtle calorie-burning activities such as short walks and light outdoor chores. These caloric expenditures may only add up to about 100 calories per day, but this translates into a 3-4 pound weight gain during the winter months.
