The Energy Within: How Inflammation Highjacks Your Metabolism
Functional Nutrition - 8 min read
You've been told your blood tests are normal. But 'normal' is built on averages - not on what thriving actually looks like. Here's what to look for instead.
Every move you make, every thought you process, and every breath you take requires energy. At the cellular level, that energy is managed through a complex system called metabolism. When it's running smoothly, you feel vibrant, clear-headed, and balanced.
But here's what most people aren't told: chronic inflammation can act like a glitch in your biological software - quietly draining your energy reserves, disrupting your weight, and contributing to brain fog - while your blood tests continue to read as perfectly normal.
This isn't a failure of your body. It's a limitation of what standard testing is designed to find.
Key markers I look at that your results may not flag
These are not obscure or experimental tests. Most of them are available through standard pathology - they're simply not always ordered, or not interpreted with optimal ranges in mind.
hs-CRP (high-sensitivity C-reactive protein) This is the gold standard for measuring low-grade systemic inflammation. A result can sit within the conventional normal range and still be elevated enough to be quietly disrupting your energy, mood, and metabolism. I look for an optimal range, not just a disease-free one.
Fasting insulin (not just fasting glucose) Most standard panels check fasting glucose, but glucose can remain normal for years while insulin resistance is already developing. Elevated fasting insulin is one of the earliest signs of metabolic stress - and one of the most actionable, because diet and lifestyle changes can shift it significantly.
Ferritin (stored iron) Low ferritin is one of the most common and most missed causes of persistent fatigue in women, particularly in perimenopause. A result that falls within the reference range can still be too low for optimal energy production. I see this frequently in clients who have been told their iron is fine.
Homocysteine Elevated homocysteine is a marker of B vitamin insufficiency and methylation dysfunction - both of which affect energy, mood, and cognitive clarity. It's rarely included in a standard panel but provides important information about how well your cells are actually functioning.
Free T3 (active thyroid hormone) TSH is the standard thyroid marker ordered in most GP panels. But TSH reflects the signal being sent to the thyroid - not what the thyroid is actually producing. Free T3 is the active form of thyroid hormone that drives your metabolism, and it can be suboptimal even when TSH looks perfectly normal.
Your Body’s Energy Currency
Think of your cells as tiny power plants. They take in raw fuel from the food you eat (carbohydrates, fats, and proteins) and convert it into a universal energy molecule called ATP (adenosine triphosphate). Over 90% of your energy is produced this way, primarily inside your mitochondria.
When your mitochondria are healthy, your body maintains a state of balance called homeostasis. When they're stressed - by inflammation, poor nutrition, chronic stress, or hormonal shifts - energy production drops. And you feel it in ways that are very real, even when a standard blood panel says nothing is wrong.
Nutritional needs change as we age.
Each stage of life requires a balanced diet which includes complex carbohydrates, anti-inflammatory fats, and proteins - the ratio of macronutrients can change baed on our metabolism.

The Inflammation Hijack
One of the most significant breakthroughs in recent science is the link between the immune system and metabolism.
When your body detects chronic stress or low-grade inflammation, your immune cells redirect resources away from long-term repair and brain function, and into what I call a biological defence mode..
This is a survival mechanism - and it's brilliant in the short term. But when it stays switched on, it leads to metabolic dysregulation. That dysregulation is a primary driver of the symptoms my clients describe most often: persistent fatigue, unexplained weight gain, brain fog, and a general sense of not feeling like themselves.
The important thing to understand is that this state can be active and measurable long before it shows up on a standard test as disease.

Support with targeted nutrients
Two of the most clinically significant nutrients for mitochondrial function are NAD+ and Ubiquinol (CoQ10) - and most people are deficient in both by their forties, often without knowing it.
Prebiotic foods nourish the microbiome
The microbiome produces short chain fatty acids that reduce inflammation and support neurotrasmitter synthesis.
NAD+ is essential for your cells to actually produce ATP. Without adequate levels, your mitochondria slow down regardless of how well you eat or sleep. NMN (Nicotinamide Mononucleotide) is one of the primary building blocks your body uses to create NAD+ but its molecules are too large to be effectively absorbed as a direct oral supplement. While the mechanics of NAD+ are vital to human energy metabolism, the evidence shows that the science on human supplementation is in its infancy. For an everyday consumer looking for an energy boost, sticking to proven lifestyle interventions (diet, sleep, and exercise) is currently the only confidently backed approach.
Ubiquinol is the active, absorbable form of CoQ10 - it acts as a cofactor in the energy production process and is one of the body's most powerful antioxidants, neutralising the oxidative stress that accumulates when your system is under inflammatory load. Together, they don't just support energy - they protect the mitochondria themselves, which is where the real long-term benefit lies.
Herb of Gold Ubiquinol 150mg is a readily available supplement and the form ubiquinol which is significantly better absorbed than standard CoQ10, or Ubidecarenone, particularly for anyone over 40 or dealing with chronic fatigue. Dosing and whether to add NAD+ support depends on your individual pathology - which is something we can assess in a consultation.
The Bottom Line
Your energy is not a willpower problem. It is a biology problem - and biology can be measured, understood, and changed.
When chronic inflammation is quietly running in the background, your body diverts resources away from repair, cognition, and vitality, and into defence. That's not a character flaw. It's a survival mechanism that has simply stayed switched on too long.
The good news is that the markers driving this are identifiable, the mechanisms are well understood, and the interventions - reducing inflammatory load, supporting mitochondrial function, and challenging your system with healthy stressors - are genuinely effective.
The difference between surviving and thriving is not as far as it feels right now. It starts with understanding what your body is actually doing, and having someone in your corner who knows how to read the full picture.
If you've been told your results are normal but you still don't feel well - that gap deserves an answer.
