Short days, low mood? Here’s how to eat your way back to sunshine.
As daylight fades and the sun rises later, many of us (especially in the northern hemisphere) notice our energy dipping and our moods slipping. It’s not just in your head — your body reacts to less light, which can lower vitamin D, slow serotonin production, and trigger carb cravings.
The good news? You can fight back with your fork.
Building a plate with mood-supporting foods can help you feel more energized, focused, and resilient all season long. From omega-3s to magnesium-rich greens, the right combination of nutrients can lift your spirits naturally and keep you feeling bright even on the darkest days.
1. Omega-3 Power Foods
Think: chia seeds, flaxseed, walnuts
Omega-3 fatty acids are essential for your brain health. Research shows they can help reduce symptoms of depression and improve overall mood by supporting neurotransmitter function and reducing inflammation (Grosso et al., 2014).
Plant-based tip: Sprinkle chia or ground flaxseed on oatmeal or smoothies for a daily brain boost.
Vitamin D–Rich Foods
Think: fortified plant milks, mushrooms, and for those who aren’t fully plant-based, salmon and eggs
Low vitamin D is linked to seasonal mood changes and fatigue. Studies suggest that maintaining adequate vitamin D levels can improve mood and may help prevent seasonal affective disorder (SAD) symptoms (Anglin et al., 2013).
Coach tip: Vitamin D is a fat-soluble vitamin, so pair vitamin D–rich foods with healthy fats, like olive oil or avocado, for better absorption.
Complex Carbs
Think: oats, quinoa, sweet potatoes, brown rice
Carbs are key for serotonin production — the “feel-good” neurotransmitter.
Not all carbs are created equally, though. Complex carbs are made of long chains of sugar molecules that digest slowly, providing steady energy and fiber, whereas refined carbs are processed, stripped of fiber and nutrients, and cause rapid spikes in blood sugar.
It’s the difference between eating brown rice and a frosted donut. The rice can give you steady energy, while the donut may cause a blood sugar spike (and eventual crash) and leave you feeling worse than before.
Choosing complex carbs keeps blood sugar stable, supporting steady energy and mood.
Simple swap: Try a warm quinoa bowl instead of cold cereal for breakfast this week.
Magnesium-Rich Foods
Think: leafy greens, pumpkin seeds, dark chocolate, beans
Magnesium supports relaxation and plays a major role in mood regulation. Low magnesium has been linked to higher anxiety and depressive symptoms (Eby & Eby, 2006).
Snack idea: A handful of pumpkin seeds with a few squares of dark chocolate is a mineral-packed mood lift.
Probiotic + Prebiotic Foods
Think: yogurt, kefir, sauerkraut, garlic, onions, bananas
Your gut and your brain communicate constantly through the gut-brain axis. Research shows that a balanced gut microbiome can improve mood and reduce anxiety (Slyepchenko et al., 2017).
Try this: Add a spoonful of sauerkraut or kimchi to your lunch bowl to support gut health.
Recipe Spotlight: Sunshine Bowl
Ingredients:
- 1 cup cooked quinoa
- ½ cup roasted sweet potatoes
- ½ cup steamed broccoli
- ¼ avocado, sliced
- 1 tbsp pumpkin seeds
- Drizzle of olive oil + squeeze of lemon
Why it works:
This combination of complex carbs, healthy fats, and magnesium-rich seeds supports serotonin production, stabilizes energy, and gives your brain the nutrients it needs to stay balanced and focused. It’s an easy, colorful, and mood-boosting way to eat for energy this season.
Non-Food Ways to Support Your Mood
Food is powerful, but it’s not the only tool. To boost mood naturally:
- Get natural light: Morning sunlight exposure helps regulate your circadian rhythm.
- Move daily: Even a 20-minute walk releases endorphins.
- Prioritize sleep: Consistent, quality sleep supports serotonin production.
- Connect socially: Time with friends, family, or support groups can reduce feelings of isolation.
- Mindfulness and relaxation: Meditation, journaling, or gentle yoga can ease stress and improve mental clarity.

If you’re experiencing persistent low mood, sadness, or symptoms of seasonal affective disorder, it’s important to reach out to a mental health professional. Licensed therapists, counselors, or physicians can provide individualized support and guidance.
Let Food + Lifestyle Choices Nourish You
Your plate and lifestyle choices together are powerful tools to help lift your mood and sustain energy through shorter days. Small changes — in what you eat, how you move, and how you care for your mind — can help you feel brighter, more energized, and resilient even on the darkest days.
