It often starts quietly. The alarm goes off in the dark. You reach for toast instead of breakfast, then biscuits at 3pm, then you’re on the sofa by 8pm wondering where your spark went.

If that sounds familiar, I want to say this first: nothing is wrong with you. You are a living being responding to less light. Our ancestors slowed down in winter. Our bodies still remember, even if our calendars don’t.

But there is a difference between a natural winter slowing and a low mood that steals your joy. Let’s gently look at both.

Winter blues are a common dip in mood and energy as daylight falls; seasonal affective disorder (SAD) is a type of depression with a seasonal pattern. Food cannot cure SAD, but steady blood sugar, enough protein, omega-3 fats, vitamin D and morning daylight can all support mood and energy through winter.

**Is it winter blues or SAD?**

Around 3% of people in Britain develop SAD each winter, and a further 20% feel a milder version often called the winter blues. So if you feel flatter in winter, you are far from alone.

Winter blues might look like wanting more sleep, more comfort food and fewer plans. SAD goes deeper: persistent low mood, losing interest in things you love, irritability, exhaustion even after rest, and strong cravings for carbohydrates.

If your low mood is lasting for weeks or affecting daily life, please speak to your GP. Nutrition and lifestyle work beautifully alongside medical support, never instead of it.

*\[Your story: a line about how you notice winter in your own body, or what helps you most.\]*

**Why do I crave carbs and sugar in winter?**

There’s real wisdom in that craving. Carbohydrates help the brain make serotonin, a chemical linked to mood and sleep. When the light fades, your body reaches for a quick lift. It is trying to help you.

The trouble is what happens next. Sugary snacks spike blood sugar and then drop it, leaving you more tired, foggy and irritable than before. So the answer isn’t to fight the craving or cut carbs. It is to offer your body something steadier: slower carbs, paired with protein.

**What foods help with winter blues?**

I think of winter food as a warm hand on the back. These are the foods I most often weave into clients’ winter plans:

- **Protein at every meal:** eggs, fish, chicken, turkey, tofu, beans, lentils and Greek yoghurt. Protein provides tryptophan, which the body uses to make serotonin.
- **Slow-release carbs:** oats, root vegetables, brown rice, rye bread and lentils, for steadier energy.
- **Oily fish twice a week:** salmon, mackerel, sardines and trout give omega-3 fats, important for brain health.
- **Seeds and nuts:** pumpkin seeds, walnuts and ground flaxseed, scattered over porridge or soup.
- **Seasonal colour:** beetroot, squash, kale and red cabbage, deep-coloured and in season.
- **Fermented foods:** live yoghurt, kefir, sauerkraut and kimchi to support the gut, which is closely linked to mood.

**Do I need vitamin D in winter in the UK?**

Yes, most of us do. The NHS says that between October and early March we can’t make enough vitamin D from sunlight. UK government advice is that everyone should consider a daily 10 microgram (400 IU) vitamin D supplement through autumn and winter.

Vitamin D supports bones, muscles and the immune system. Some people need it all year, including those with darker skin and those who rarely get outside. If you take medication or have a health condition, check with your GP or pharmacist first.

**Six small rituals for brighter winter days**

Rather than a list of rules, I like to think of these as little acts of care:

1. **Meet the morning light.** Step outside within an hour of waking, even for five minutes. A cloudy sky still gives far more light than indoors.
2. **Warm, protein-rich breakfasts.** Eggs on rye, or porridge with seeds and yoghurt, instead of toast and jam.
3. **Eat with a rhythm.** Regular meals keep your energy from swinging.
4. **Move like it’s a pleasure.** A walk, some yoga, dancing in the kitchen while the kettle boils.
5. **Honour your sleep.** Dim the lights and screens an hour before bed, like a slow sunset indoors.
6. **Stay held.** Winter pulls us inward, but connection protects our mood. Call a friend. Join a circle.

**Pause and reflect**

Take a quiet moment with a warm drink and ask yourself:

- How does my body feel when the light changes?
- What does “comfort” really mean to me in winter, beyond food?
- What is one small thing that reliably lifts me, even a little?

Write the answers somewhere you’ll see them on the grey days.

**How can a nutritional therapist help with low winter mood?**

When I work with someone, I look at the whole picture: what you eat, how you sleep, your energy, stress, gut health and hormones. For many women, winter low mood overlaps with perimenopause, burnout or simply carrying too much.

Together, we find the few changes that matter most for you, and build them gently into real life. No rigid diets, no guilt.

**Frequently asked questions**

**Can diet help seasonal affective disorder?**

Diet cannot cure SAD, but it can support mood and energy. Regular meals with protein, slow-release carbohydrates, oily fish, and vitamin D in winter are a helpful foundation. Always speak to your GP if low mood is persistent or affecting daily life.

**How much vitamin D should I take in winter in the UK?**

UK government and NHS advice is that adults should consider a daily supplement of 10 micrograms (400 IU) of vitamin D from October to March. Some groups are advised to take it all year. Check with a pharmacist or GP if unsure.

**What should I eat for breakfast to boost my mood in winter?**

Choose a breakfast with protein and slow-release carbohydrates, such as eggs on rye toast, porridge with seeds and yoghurt, or a savoury lentil and vegetable hash. This keeps blood sugar steady and helps avoid a mid-morning slump.
