The science-based plan to restore optimal mental health with metabolic magic.
What if mental illness is also an energy problem?
​
Mood, Mind & Mitochondria reveals the overlooked connection between brain energy, metabolism and mental health - and offers a practical route towards restoring resilience, hope and control.

Fatigue. Brain fog. Anxiety. Low mood. Poor motivation. Disrupted sleep.
​These experiences are often treated as separate symptoms - or as problems that exist only in the mind. But every thought, feeling and action depends on living cells producing, directing and using energy.
A new way of understanding mental health
Conventional Approach
-
The brain is seen as separate from the body
-
Symptoms are considered mainly psychological or psychiatric
-
Diagnoses are treated as separate conditions
-
Treatment focuses mainly on managing symptoms
Metabolic Lens
-
Mental health is also influenced by the biology of the brain and body
-
Different diagnoses can share disrupted metabolic pathways
-
Metabolic health may offer additional routes to recovery using food and lifestyle medicine
This is not about replacing medication, psychological support or psychiatric care. It is about adding a vital and often overlooked piece of the picture. One that might have life changing consequences.
This book will help you understand...
-
Why the brain’s extraordinary energy demands may make it vulnerable to metabolic dysfunction
-
Why mitochondria are far more than cellular batteries
-
How insulin resistance, inflammation and oxidative stress can affect the brain
-
How food, sleep, light, stress, movement and connection influence cellular energy
-
Why ketogenic therapy is attracting interest in mental-health research
-
How to create a safe, personalised plan using the MitoMind™ Method
I did not begin with a theory. I began by losing my health.
I lived through profound fatigue, anxiety, depression, brain fog, depersonalisation and derealisation. I struggled to get off the couch and could barely care for my children. I no longer had the energy even to smile.
​
It did not feel as though it was all in my head. It felt as though my whole system had run out of usable energy.
​
Understanding metabolism and changing the signals reaching my body transformed my health. It led to the question: what does energy have to do with the mind and how does it affect our mood?

What other people are saying...
"You cannot have a healthy and happy brain without the right fuel and a healthy engine - which is the mitochondria in every cell. This book is a superb guide to how to upgrade your brain and reclaim your mental health.”
​
Patrick Holford, Founder of the Food for the brain Foundation and the Institute for Optimum Nutrition
“Mood, Mind & Mitochondria is exactly the book the field of metabolic psychiatry has needed. The author masterfully bridges the gap between cutting-edge mitochondrial science and practical, personalized mental health strategies. The illustrations bring complex concepts like brain energy resistance and metabolic signalling to life in a way that's immediately accessible. The information is both comprehensive and actionable, guiding readers from foundational science through to the MitoMind Method with clarity and clinical precision. This book will be a go-to resource for clinicians and patients alike who recognize that mental health is, at its core, a metabolic challenge."
​
Dominic D'Agostino, PhD Associate Professor, USF Morsani College of Medicine; Research Scientist, Institute for Human & Machine Cognition
“Mood, Mind & Mitochondria offers a fascinating and deeply important perspective on mental health through the lens of cellular health and metabolism. As a psychiatrist with 22 years of clinical experience, I have personally witnessed the power of dietary and metabolic strategies in transforming mental health symptoms, including people emerging from severe depressive episodes far faster than I ever observed with drug-based approaches alone. This book challenges conventional thinking while offering hope, science, and practical tools for restoring brain health at the root cause level.”

Dr Rachel Brown, MBChB LLM MRCPsych CFMP BCAQB
“Mood, Mind & Mitochondria is a lovely combination of science, hope and practical implementation for people seeking psychiatric recovery. The book covers the new science of brain energy and mental illness and walks readers through what happens as treatment begins to work, the kind of practical information rarely written for the public. Recovery stories offer honest hope built on what the author lived through herself, and the practical sections give readers not only a real starting place but valuable guidance for issues that present themselves as recovery unfolds.”
