You wake up tired. The afternoon slump hits hard. You feel mentally foggy or physically drained, and yet your test results come back “normal”. Sound familiar? Unexplained fatigue is one of the most common reasons people seek help, and it’s rarely solved by more coffee or sleep alone.
At The Heart of the Matter Nutrition, we understand that chronic tiredness is often a sign of something deeper. Whether it’s hormonal, digestive, nutritional, or stress-related, fatigue is your body’s way of saying: slow down and listen.
What Is Unexplained Fatigue?
Unexplained fatigue refers to ongoing low energy that doesn’t improve with rest and isn’t explained by a diagnosed condition. It can be physical, mental, or both, and it often builds slowly over time.
Common signs include:
Struggling to get out of bed
Craving caffeine, sugar, or naps to stay alert
Feeling ‘wired but tired’ in the evenings
Brain fog or lack of focus
Irritability or low mood
Muscle heaviness or sluggishness
If you’ve been told you’re just “stressed” or “getting older,” but something still feels off, your fatigue may have a root cause that’s been missed.
Nutritional Causes of Fatigue
One of the first areas we explore is nutrition. Even subtle imbalances can affect energy levels.
At The Heart of the Matter Nutrition, we often see the following patterns:
Low iron or B12 levels, particularly in women with heavy periods
Poor blood sugar control, which creates highs and crashes in energy
Low protein intake, leading to poor muscle repair and mood imbalances
Inadequate dietary fibre, affecting gut health and nutrient absorption
Through functional assessments and personalised guidance, we help clients build energy from the inside out, with real food, not rigid rules.
Gut Health and Fatigue
Your gut does more than digest food, it also influences energy, mood, and immune function. When digestion is compromised, so is your ability to absorb vital nutrients.
Signs your gut may be contributing to unexplained fatigue include:
Bloating or gas after eating
Constipation or irregular bowel movements
Frequent illness or low immunity
Brain fog after meals
Our online nutrition programmes help restore gut health step-by-step, using lifestyle strategies and real-food nourishment tailored to your needs.
Hormonal and Stress-Related Fatigue
Hormonal imbalances, particularly in the thyroid, adrenals, or reproductive system, can drain your energy over time. So can long-term stress, which affects sleep, digestion, and nervous system regulation.
You may notice:
Fatigue that worsens mid-afternoon
Sleep that feels unrefreshing
Increased sensitivity to stress or noise
Low mood or irritability, especially around your cycle
Cravings for salty or sugary foods
We support clients through these challenges by looking at the full picture and designing a personalised roadmap, often using insight from functional testing.
Why Personalised Care Matters
You don’t need to “push through” or accept exhaustion as normal. Your body has a reason for feeling this way, and your care plan should reflect that.
Assess your health history, symptoms, and patterns in depth
Use functional insights where needed to uncover hidden imbalances
Help you build sustainable habits that actually restore energy
Support you at your pace, no more going it alone
If you're tired of feeling tired, it’s time to find out what your body is really trying to say. Let’s uncover the root of your unexplained fatigue and create a personalised plan to help you feel energised, clear-headed, and truly supported.
