Winter hunger: Why we crave comfort food when it gets cold
(Global Heart) Have you ever wondered why you can’t stop snacking as soon as the temperature drops? From biological heaters to “happy hormones,” here is why winter hunger is a natural seasonal change—and how to tell when it might be a sign of something more.
Why do we feel so much hungrier in the winter?
Have you noticed that as soon as the temperature drops and the days get shorter, your appetite seems to do the exact opposite? One minute you’re happy with a light summer salad, and the next, you’re daydreaming about a mountain of mashed potatoes or a thick, cheesy lasagna.
If you feel like a bottomless pit during the winter months, don’t worry—you’re not alone, and you’re certainly not “losing control.” There are some very real, scientific reasons why our bodies demand more fuel when the frost sets in.
It’s a matter of biological survival
The most basic reason for winter hunger is thermogenesis. Your body is essentially a biological heater that needs to stay at a steady 98.6 degrees Fahrenheit (about 37 °C). When it’s freezing outside, your system has to work overtime to maintain that core temperature.
To do this, your metabolism kicks up a gear. You might start shivering—which burns energy through muscle contractions—or your body might start burning “brown fat,” a special kind of tissue that turns calories directly into heat. This extra work requires “fuel,” which is why your brain sends out those loud hunger signals.
The digestion “heater”
Interestingly, the act of eating itself helps keep you warm. This is known as the thermic effect of food. When your gut breaks down complex carbohydrates and fiber, it produces heat. It’s almost like putting a log on a fire; your body knows that a heavy meal will result in a internal temperature boost that lasts for hours.
The search for serotonin
It isn’t just the cold that affects us; it’s the darkness. Sunlight is a major trigger for the production of serotonin, often called the “happy hormone.” During the bleak stretch of winter, our serotonin levels can dip, which can lead to lower moods or even Seasonal Affective Disorder (SAD).
Because serotonin also helps suppress appetite, a drop in this hormone can lead to cravings—specifically for carbohydrates. Carbs give us a quick energy burst and actually help the brain release more serotonin, making them a natural (and delicious) way to self-soothe when the winter blues hit.
Why we reach for the carbs
It’s no coincidence that we crave stews and casseroles instead of cold juices in January. High-carb and high-protein meals provide:
- Quick energy: Perfect for meeting the increased metabolic demand.
- Maximum heat: These foods create a larger thermic effect during digestion than fats do.
- Emotional comfort: They provide that much-needed serotonin boost.
Add to this the fact that we’re often more dehydrated in winter (because we don’t feel as thirsty in the cold), and it’s easy to see why we feel so hungry. Sometimes, a “hunger pang” is actually just your body asking for a glass of water.
Listening to your body’s rhythm
In a world obsessed with “bikini bodies” and constant weight loss, it’s easy to feel guilty about winter weight gain. However, experts suggest we should view this as a natural seasonal rhythm. Just as trees lose their leaves and animals hibernate, the human body adapts to the environment.
Putting on a pound or two during the winter is often just your body doing its job. Instead of fighting it, try to find a balance. Enjoy those hearty comfort foods, but try to pair them with fiber-rich winter vegetables like carrots or parsnips to keep your digestion smooth.
When to check in with yourself
While an increased appetite is normal, it’s always good to stay mindful. If you feel like your eating habits are becoming a way to fill an emotional void, or if you feel completely out of control around food, it might be worth chatting with a professional.
But for most of us? It’s simply “soup season.” So, grab a bowl, get cozy, and remember to be kind to yourself. Your body is just trying to keep you warm.
