Why Am I Hungrier in the Fall and Winter?

Some people experience a mild uptick in hunger, while others feel like they could snack all day. The good news is that (in most cases) this increased appetite in winter is a normal, predictable response to changes in light, routine, mood, and even what foods are easiest to access in colder months.

Why Hunger Increases in Colder Months

Evolutionary Factors

According to a study published in the European Journal of Clinical Nutrition, people consumed an average of 86 more calories per day in the fall and winter compared with spring. People also ate more fat and saturated fat in the winter months. This increased appetite may reflect an evolutionary "relic" that tells us to eat more now because food may become scarce in the darkest part of winter.
Even though most of us aren't facing true seasonal food scarcity anymore, our biology still responds to seasonal cues. When you combine that ancient "store up energy" signal with modern access to highly palatable foods, hunger and cravings can feel amplified.

Shorter Days and Serotonin

Sunlight triggers the release of serotonin, a neurotransmitter that boosts mood. With shorter days, you'll likely get less sunlight and fewer serotonin boosts. Your body may seek that "happy" feeling from other sources, one of which is food. Carbohydrates, like sunlight, can increase serotonin levels, so cravings for carbohydrate- and fat-rich comfort foods often rise in winter.
Less daylight can also subtly shift your circadian rhythm (your internal clock). When your sleep and wake patterns change, hunger hormones can change too, and it may become harder to sense true physical hunger versus "I'm tired and need a pick-me-up."

Comfort Foods, Mood, and SAD

Comfort foods taste good, remind us of home and gatherings, and can make us feel better. For some, seasonal affective disorder (SAD) can intensify appetite changes, often described as seasonal affective disorder appetite shifts, making winter cravings especially strong. If the cold and dark feel depressing, reaching for a warm bowl of macaroni and cheese can be both mentally and physically comforting.

It's also common for winter routines to feel more isolated: fewer outdoor activities, fewer spontaneous meetups, and more time at home. When stimulation and connection go down, eating can become an easy source of pleasure, comfort, and "something to do."

Cold Weather and Energy Needs

Your body works to maintain a steady internal temperature. In very cold conditions, the body can burn more energy through a process called thermogenesis. While many of us spend winter indoors with heat, even small increases in energy use, plus heavier clothing and more time sitting, can create mixed signals: you may feel hungrier even if your total movement decreases.

Sleep Changes and Stress

Holiday schedules, end-of-year deadlines, travel, and disrupted sleep can all affect appetite. When you're sleep deprived, hunger hormones may increase and cravings (especially for quick energy foods like sweets and refined carbs) can rise. Stress can have a similar effect by increasing the desire for soothing, familiar foods.

Environment and Seasonal Food Cues

Winter is full of cues that can increase eating: holiday treats at work, family gatherings, baked goods at home, and "seasonal" drinks and desserts everywhere you go. These cues don't mean you lack willpower; they simply make eating more likely. Add in colder weather (which can make fresh produce feel less appealing), and it makes sense that hearty foods become the default.

Strategies to Manage Winter Hunger

Get daylight exposure whenever possible. Sunlight supports serotonin release, helping boost mood without relying on food. If it's safe and accessible, a short morning walk can be especially helpful for setting your body clock.
Stay hydrated as you would in warmer months. In colder weather, try tea or hot water with lemon to stay warm and add gentle fullness. Sometimes thirst can show up as "snacky" feelings.
Choose in-season fruit for snacks. Fresh citrus is ideal in winter; lemons and tangerines peak from late October to January; wide orange varieties are best from December through March or April.
Build more satisfying meals. Aim to include protein, fiber, and healthy fats at meals to support satiety. For example: eggs plus sautéed greens and avocado; Greek yogurt plus berries and nuts; or a grain bowl with beans, roasted vegetables, and olive oil.
Warm, volume-rich foods can help. Many people feel more satisfied with warm foods in winter. Soups, stews, and roasted vegetables can provide a lot of volume and nutrients without requiring constant snacking.
Plan for comfort on purpose. Instead of trying to eliminate comfort foods, decide how to enjoy them. Pair your favorite pasta with a big salad, add extra vegetables to mac and cheese, or serve dessert in a small bowl and eat it slowly.
Check in with your sleep. A consistent bedtime, dimmer lights in the evening, and less scrolling before bed can make a noticeable difference in cravings the next day.

Nourishing Winter Food Ideas

• Soups, broccoli, cauliflower, and Brussels sprouts (roasted or added to soups and sheet-pan meals)
• Salmon for vitamin D and omega-3 fatty acids
• A small bite of dark chocolate to help lift mood and increase satiety
• Oats with chia, cinnamon, and fruit for a warm, fiber-rich breakfast
• Beans and lentils for protein and fiber (try lentil soup, chili, or bean salads)
• Root vegetables like sweet potatoes, carrots, parsnips, and beets (roast a tray for easy add-ons all week)
• Herbs and spices like ginger, turmeric, garlic, and cinnamon to add warmth and flavor

When Hunger Feels "Too Much"

If your hunger feels intense, constant, or out of character, it can help to zoom out and consider patterns. Are you eating enough at meals? Are you skipping breakfast and then feeling ravenous at night? Are you using snacks to cope with stress, loneliness, or fatigue?
Sometimes increased hunger is a sign that your body genuinely needs more fuel (for example, during growth, higher training volume, or recovery from illness). Other times, it can be a sign your body is under-slept, under-nourished, or under-supported emotionally. If hunger changes are sudden, accompanied by significant weight changes, or feel distressing, consider talking with a healthcare professional or registered dietitian for personalized support.
Bottom Line
It's natural to feel hungrier when days are shorter and temperatures drop. It's okay to enjoy comfort foods sometimes; aim for balance, reach for nutrient-dense options, and feel great all through fall and winter.
