There’s a moment every year when you feel it. The light fades earlier. Your appetite changes. You crave warmth. Mornings feel a little heavier, cold salads lose their appeal and hearty stews start to make sense.
And yet, most of us keep trying to live like it’s June.
Modern life doesn’t recognise seasons. Supermarkets stock summer fruits and vegetables year-round. Gyms stay brightly lit late into the evening. Productivity expectations don’t shift when the sun sets at 4pm.
But your biology still does.
From an ancestral perspective, winter wasn’t just colder, it placed different demands on the body. Energy conservation, immune resilience, nutrient density, warmth, repair. Instead of pushing through winter, what could we unlock if we adjusted with it?
Here are seven ways to support your body through the colder, darker months, rooted in ancestral nutrition, designed to work with the season and not against it.

Protein isn’t just about muscle. It’s structural and protective. Cold weather subtly increases energy expenditure and winter is also peak season for infections, which raises protein requirements for immune cell production and tissue repair.
Ancestrally, winter diets centred around nutrient-dense animal foods, including slow-cooked meats, broths, organ cuts, rich in complete amino acids, zinc, iron and B vitamins. Stored animal foods were what was readily available during the colder, darker months when fresh fruit and vegetables were scarce and this higher protein intake supported the body for repair and immunity.
How to apply it to real life:
Aim for adequate daily protein (around 1.6g/kg bodyweight is a useful benchmark for many adults).
Prioritise complete protein sources, like meat, fish, eggs, dairy or a natural protein supplement.
Distribute protein evenly across meals.
Collagen-rich foods, collagen supplements and bone broth are also particularly useful in winter. The glycine within collagen supports connective tissue and for those training indoors or increasing strength work, collagen supplementation can also support joint comfort and mobility.
Winter is not the season for under-eating protein.
Around 70% of immune tissue is associated with the gut. That matters more in winter. In the past decade, research into the gut–brain axis has reshaped how we understand the microbiome, not as a passive digestive system, but as an active regulator of immunity, mood and whole-body resilience.
Seasonal shifts often mean less dietary diversity, more refined “comfort” foods, and reduced sunlight exposure, which influences circadian rhythm and gut motility. Historically, winter diets also included preserved fermented foods, collagen from slow cooking, and cooked vegetables rather than large raw salads.
How to apply it to real life:
Consume fermented foods regularly as part of a balanced diet. Make sure to include both probiotics (live beneficial bacteria from fermented foods like kefir, yoghurt and sauerkraut) and prebiotics (the fibres that feed them, found in foods like onions, garlic and oats). Feeding your microbiome is just as important as introducing new strains!
Favouring cooked vegetables. The cooking process softens fibre and can make vegetables easier to digest, particularly if your gut feels more sensitive in winter.
Adding collagen or bone broth to meals. Collagen contains the amino acid glutamine which supports a healthy gut lining.
Ensuring adequate zinc intake e.g. red meat, shellfish (particularly oysters), eggs and pumpkin seeds. Zinc plays a role in immune cell function and gut barrier integrity.
Warmth in winter is not just about comfort. It’s metabolic.
Cold exposure increases thermogenic demand (the energy required to maintain your body temperature). Chronic under-fuelling during winter can increase cortisol and strain thyroid function.
Ancestrally, winter meant more cooked meals, greater reliance on stable natural fats and energy-dense foods to match environmental stress.
How to apply it to real life:
Prioritise warm, cooked meals. This supports easier digestion and energy balance.
Be mindful of under-fuelling. Structured approaches like intermittent fasting can work for some, but winter isn’t the season for chronic energy restriction if recovery, mood or immunity are suffering.
Try incorporating warming ingredients like ginger and cinnamon.
Winter nourishment should feel grounding, not restrictive.
Immune systems are built daily, not boosted overnight.
Your immune response relies on a constant supply of nutrients to produce white blood cells, antibodies and signalling molecules. In winter, lower sunlight exposure, increased indoor living and higher pathogen exposure can all increase immune demand. At the same time, vitamin D levels often fall, sleep can become disrupted, and stress tends to rise, all of which influence immune regulation.
How to apply it to real life:
Ensure you get adequate protein. Immune cells and antibodies are synthesised from amino acids, so protein is foundational to the immune response and recovery.
Ensure sufficient vitamin D by maximising time outdoors or through a high-quality, natural supplement. This is particularly relevant in UK winters with minimal UVB exposure.
Ensure a good intake of zinc and selenium in foods like red meat, oysters, eggs, Brazil nuts and pumpkin seeds.
Get consistent sleep. Deep sleep is when much of your immune regulation occurs and even short-term sleep restriction has been shown to reduce immune resilience.
Stress regulation. Chronic stress elevates cortisol, which can suppress aspects of immune function over time.
Your circadian rhythm is regulated primarily by light exposure, with morning daylight signalling wakefulness and evening darkness triggering the release of sleep hormones. Reduced daylight in winter directly influences the pathways of melatonin (sleep hormone) and serotonin (hormone that supports wakefulness), meaning energy and mood fluctuations can be common.
How to apply it to real life:
Get outside within 30 minutes of waking, even for 5–10 minutes. Morning light exposure helps anchor your circadian rhythm, reinforcing daytime alertness and improving the quality of sleep later that night.
Dim artificial lighting after sunset. Lowering light intensity in the evening supports natural melatonin release, which protects sleep quality and next-day energy.
Keep meal timing consistent day to day. Regular eating patterns act as secondary circadian cues, helping stabilise metabolic rhythm when natural light exposure is reduced.
Use MCTs strategically, particularly in the morning. MCTs are rapidly converted into usable energy, which may support mental clarity during darker mornings without relying solely on caffeine.
If winter can affect your energy, it can also affect your recovery. Sleep is when much of the body’s repair work takes place, including immune regulation, tissue recovery, memory consolidation and hormonal recalibration. In colder months, when immune exposure is higher and energy demand increases, the quality of your sleep becomes even more important.
Rather than overriding winter tiredness with stimulation, there’s value in respecting it. Seasonal fatigue is not always a flaw, sometimes it’s a signal that recovery needs have increased. Winter is not the time to shorten sleep. It’s the time to protect it.
How to apply this to real life:
Keep your sleep and wake times consistent. Regular timing strengthens your internal rhythm, improving sleep depth and helping stabilise next-day energy.
Prioritise a cool, dark sleep environment. A darker, slightly cooler room supports deeper stages of sleep and more effective overnight recovery.
Reduce evening stimulation. Lowering late-night mental and physical intensity supports parasympathetic activity, allowing the body to transition into restorative sleep more easily.
Try winding down with a warm mug of bone broth. Bone broth and collagen contain the amino acid glycine that supports restful sleep.
Support relaxation with nutrient sufficiency. Adequate magnesium and glycine-rich foods, such as collagen, bone broth or electrolytes, may help promote nervous system calm and improve sleep quality.
Winter has historically been a higher-fat season. In colder months, dietary fat provides dense, stable energy to support thermogenesis (heat production), hormone balance and sustained satiety. It also enables the absorption of fat-soluble vitamins such as A and D, which are both particularly relevant when sunlight exposure drops.
The emphasis is on quality, not excess. Traditional, minimally processed fats are more stable for cooking and align with both ancestral dietary patterns and modern understanding of lipid oxidation. In winter, nourishment should feel grounding and steady, not restrictive.
How to apply this to real life:
Cook with stable, natural fats. Using options such as tallow, ghee or extra virgin olive oil for appropriate cooking temperatures reduces oxidative stress compared to refined seed oils and provides a more stable energy source.
Include a source of natural fat at each main meal. Pairing protein with healthy fats supports satiety and helps maintain steadier energy across shorter, darker days.
Winter isn’t just dietary. An ancestral winter meant:
Slower evenings.
Greater emphasis on community.
Reduced travel.
More time indoors, but not isolated.
Exposure to natural daylight when available.
Modern translation might look like:
Walking outdoors daily, even when cold.
Reducing late-night screen exposure.
Adjusting training intensity if recovery feels compromised.
Protecting mental wellbeing proactively as daylight shortens.
Using heat and cold exposure intentionally, not performatively.
Winter is not something to push through. It’s a phase to prepare for, align with, and respect.
Instead of fighting winter, support it. Prioritise protein. Protect your gut. Eat warm, stable fats. Support immunity daily. Stabilise energy. Honour sleep. Adjust lifestyle rhythms. Your body still recognises the seasons, even if modern life pretends they don’t exist. Winter wellness isn’t about doing more. It’s about doing differently.
