We all have those days when the couch calls our name and coffee feels like a lifeline. But when fatigue becomes a constant companion, it’s more than just an inconvenience — it starts to affect work, relationships, and the things we enjoy.
The tricky part? Fatigue isn’t a one-size-fits-all problem. It can be caused by anything from lack of sleep and stress, to medical conditions or nutrient deficiencies. That’s why a personalised approach is so important.
Why Nutrition Plays a Key Role in Energy Levels
Our bodies are like engines — they run on fuel, and the quality of that fuel matters. Poor nutrition, skipped meals, or unbalanced diets can leave us running on empty, even if we’re eating enough calories.
Eating the right mix of carbohydrates, proteins, fats, vitamins, and minerals helps:
Stabilise blood sugar levels so energy is steady, not spiking and crashing.
Support brain function so you can think clearly.
Maintain muscle strength so physical activity feels easier.
Promote better sleep so rest actually recharges you.
Common Nutrition-Related Causes of Fatigue
Iron Deficiency – Low iron can lead to anaemia, a common cause of persistent tiredness.
Low B12 Levels – Important for red blood cell production and nervous system function.
Not Enough Protein – Protein helps repair tissues and keeps you feeling fuller for longer.
Blood Sugar Imbalances – Too much refined sugar can cause quick highs followed by energy crashes.
Dehydration – Even mild dehydration can make you feel sluggish and unfocused.
A dietitian can help identify whether nutrition is contributing to your fatigue — and guide you towards sustainable changes.
Simple Food Strategies to Support Energy
1. Eat Regularly Skipping meals often backfires, leading to dips in energy and overeating later. Aim for balanced meals every 3–4 hours.
2. Prioritise Protein Include a protein source in each meal — eggs, lean meat, fish, dairy, legumes, tofu, or nuts.
3. Choose Slow-Release Carbs Whole grains, oats, brown rice, and starchy vegetables release energy steadily rather than in short bursts.
4. Stay Hydrated Water is your best friend for energy. Herbal teas and water-rich foods like fruit can help too.
5. Include Healthy Fats Avocado, olive oil, nuts, and seeds help support brain function and keep you satisfied.
6. Limit Processed Sugars Sweet treats are fine in moderation, but too many can trigger energy crashes.
When Fatigue is Linked to Health Conditions
Sometimes fatigue is part of a bigger picture. Conditions like thyroid disorders, coeliac disease, diabetes, chronic fatigue syndrome, or depression can all play a role. In these cases, nutrition is still important — but it should be part of a broader healthcare plan.
At Dietitians NT, we often work alongside GPs and specialists to make sure nutrition plans complement medical treatment.
Beyond Food: Lifestyle Tips to Help Beat Fatigue
While nutrition is a major player, energy levels are also influenced by:
Sleep quality – Aim for 7–9 hours most nights.
Physical activity – Gentle movement can boost energy, while overtraining can drain it.
Stress management – Mindfulness, deep breathing, or simply taking breaks can help.
Pacing yourself – Learning to manage energy output can prevent burnout.
What a Dietitian Can Offer for Fatigue Management
Working with a dietitian isn’t about giving up your favourite foods — it’s about creating a plan that works for you. At Dietitians NT, we:
Assess your current diet and lifestyle.
Identify possible nutritional gaps.
Create realistic, enjoyable meal plans.
Provide ongoing support and adjustments as your needs change.
