Feeling Stressed, Tired and Overwhelmed? How Nutrition Can Help Support Your Body.
As we move into October, the slower pace of summer feels like a distant memory. Work commitments are building, school routines are in full swing, diaries are filling up, and for many of us, life can start to feel a little overwhelming.
Perhaps you’re waking up tired despite a full night’s sleep, reaching for another coffee by mid morning, experiencing afternoon energy crashes or finding yourself craving sugar more than usual.
Sound familiar?
Stress doesn’t just affect how we feel mentally. It can also influence our digestion, appetite, sleep, energy levels and the food choices we make.
As a nutritionist, I believe understanding how our bodies respond to stress is an important first step towards supporting our long term health.
What Happens to Our Bodies When We’re Stressed?
When we experience stress, our bodies activate a natural survival response, often referred to as fight or flight.
This involves the release of hormones including adrenaline and cortisol, which help us respond to immediate challenges.
In small amounts, this response is completely normal and useful. However, when stress becomes persistent and recovery time is limited, it can begin to affect our everyday wellbeing.
You might notice:
Feeling tired but struggling to switch off at night
Craving sugary foods or carbohydrates
Digestive discomfort, bloating or changes in bowel habits
Difficulty concentrating or feeling mentally foggy
Changes in appetite
Increased irritability or feeling overwhelmed
Poor quality sleep
These symptoms aren’t always caused by stress. Iron deficiency, thyroid problems, sleep disorders and other medical conditions can produce similar symptoms, so persistent fatigue deserves proper investigation.
The Connection Between Stress and Nutrition
One of the first things to change when we’re busy or overwhelmed is often the way we eat.
Breakfast gets skipped, lunch becomes something grabbed between meetings, coffee replaces proper meals, and by late afternoon we’re exhausted and searching for something sweet.
Unfortunately, these habits can make it harder to maintain consistent energy and concentration.
The good news?
Supporting your body through nutrition doesn’t have to mean complicated diets, expensive supplements or hours of meal preparation.
Sometimes the simplest changes make the biggest difference.
6 Nutrition Strategies to Support Your Body During Stress
1. Balance Your Blood Sugar
Have you ever felt energised immediately after eating something sweet, only to feel tired or hungry again shortly afterwards?
Meals built around refined carbohydrates alone may leave some people feeling less satisfied than meals containing protein, fibre and healthy fats.
Try combining:
Porridge / granola with Greek yoghurt, cinnamon and warm berries
Eggs with wholegrain toast and avocado
Apple slices with almond butter
Chicken or chickpeas with roasted vegetables and quinoa with tahini dressing
My tip: Rather than removing carbohydrates, think about what you can add to make your meals more balanced.
2. Don’t Underestimate Magnesium
Magnesium contributes to normal nervous system function, muscle function and energy metabolism.
It’s an important mineral that can sometimes be overlooked when our diets become repetitive or heavily reliant on convenience foods.
Good food sources include:
Pumpkin seeds
Almonds and cashews
Spinach and other leafy greens
Beans and lentils
Wholegrains
Dark chocolate
A handful of pumpkin seeds sprinkled over your morning yoghurt or lunchtime salad is an easy way to increase your intake.
3. Eat Enough Protein
Protein isn’t just for building muscle.
It provides amino acids needed for tissue maintenance and the production of many important substances within the body, including neurotransmitters.
Including protein at regular meals can also help with fullness and maintaining muscle mass.
Think eggs, fish, chicken, Greek yoghurt, tofu, lentils and beans.
If you’re constantly hungry or reaching for snacks throughout the day, take a look at how much protein you’re including at breakfast and lunch.
4. Support Your Gut Health
Have you ever noticed your stomach becoming unsettled during particularly stressful periods?
Our digestive system and brain communicate through what is known as the gut–brain axis.
Stress can influence gut movement, sensitivity and digestive symptoms, while our gut microbiome is also involved in complex interactions with the nervous system.
Supporting digestive health through food is a sensible starting point.
Try including:
A variety of vegetables and fruits
Fibre-rich foods such as oats, beans and lentils
Fermented foods such as live yoghurt or kefir, if tolerated
Plenty of fluids throughout the day
Increase fibre gradually, particularly if you already experience bloating or digestive discomfort.
Although gut health and mental wellbeing are connected, there is still much to learn about whether specific dietary changes can directly reduce stress.
5. Be Mindful of Caffeine
When we’re exhausted, coffee can feel like the only answer.
But relying on caffeine to get through the day can sometimes create a difficult cycle.
Caffeine may temporarily improve alertness, but consuming too much or drinking it later in the day can interfere with sleep, particularly if you’re sensitive to its effects.
Try:
Having breakfast before your second coffee
Switching to decaf later in the day
Drinking water regularly
Avoiding caffeine close to bedtime
You don’t necessarily need to give up your morning coffee. It’s about understanding how caffeine affects your individual body.
6. Nourish Your Body, Not Just Your Schedule
When life gets busy, we often prioritise everything and everyone else before ourselves.
But eating well doesn’t need to become another stressful task.
A few simple habits can make a real difference:
Prepare extra portions at dinner for the following day’s lunch.
Keep eggs, tinned fish, frozen vegetables, fruits and wholegrains available.
Choose simple, balanced meals rather than complicated recipes.
Take a proper lunch break away from your desk when possible.
Avoid routinely skipping meals because you’re too busy.
Consistency matters far more than perfection.
Could Your Fatigue Be Telling You Something Else?
One area I feel particularly strongly about is recognising when tiredness and stress related symptoms may need further investigation.
It’s easy to assume that feeling exhausted is simply part of modern life.
However, persistent fatigue can sometimes be associated with nutritional deficiencies, hormonal changes, inadequate sleep or underlying medical conditions.
For women, changes during the menstrual cycle and perimenopause can also influence sleep, mood and energy.
A personalised nutritional assessment can help identify dietary gaps, review lifestyle factors and establish whether further medical assessment or blood tests might be appropriate.
You don’t have to wait until you’re completely burnt out before prioritising your health.
My October Nutrition Challenge
This month, rather than attempting a complete lifestyle overhaul, choose just three small habits:
Eat a balanced, protein-rich breakfast.
Include at least one additional portion of vegetables each day.
Take 15 minutes away from work to enjoy lunch without distractions.
Give yourself two weeks to practise these habits and notice how you feel.
Remember, nutrition is one part of managing stress. Sleep, movement, rest, supportive relationships and reducing overwhelming demands are equally important.
