Gut Health: The Microbiome, Metabolism & Modern Disease
Clinician-level training that brings together world-leading experts in metabolic health, gastrointestinal science, ancestral nutrition, immune function, movement physiology, and oral-systemic health.
From hormones to the mouth, the gut connects it all
Twenty-one lectures link gut science with metabolism, diet, hormones, immunity, mental health, movement, and oral health.
The gut-metabolic connection
Anatomy and physiology of the GI tract, an introduction to the microbiome, and the gut-liver-metabolism connection.
Diet and the gut
Low-carbohydrate approaches in theory and practice, a metabolically flexible gut, and a closer look at animal-based diets, fat, and fibre.
Carbohydrate restriction in clinical care
Carbohydrate restriction as a treatment modality for common gastrointestinal complaints and conditions.
Mind, brain, and addiction
The gut-brain axis, stress, mood, and cognition, plus the gut microbiome and addiction.
Fasting, movement, and sleep
How nutritional rest, physical activity, and circadian rhythms shape the microbiome and intestinal integrity.
Immunity and inflammation
The microbiome's role in immune response, autoimmunity, and inflammatory disease.
Hormones, fertility, and the mouth
The link between gut health and reproductive endocrinology, and the two-way relationship between oral and metabolic health.
The microbiome through life
The gut microbiome throughout life, and how industrial food, soil degradation, and nutrient loss relate to gut dysfunction and chronic illness.
Clinical gut health management
An integrative approach to clinical gut health management, GLP-1s and the gut, and a practitioner's toolkit.
The gut is the metabolic command centre
Once viewed as an isolated system, the gut is now recognized as the metabolic command centre, shaping inflammation, immunity, hormone balance, nutrient processing, mental health, and cardiometabolic risk.
This training goes beyond microbiome basics. It explores how industrialized food systems, environmental shifts, metabolic dysfunction, and modern lifestyles have altered human gut ecology, and how clinicians can restore it using practical, evidence-based frameworks.
Metabolic dysfunction, obesity, autoimmune disorders, allergies, mental health challenges, digestive disorders, and fatty liver disease are all increasingly linked to the health of the gut ecosystem. This training helps you move from symptom management to root-cause metabolic restoration.
Functional gastrointestinal disorders (FGIDs), including bloating, abdominal pain, and irregular bowel habits, affect more than 40% of people worldwide.
What you will be able to do after this training
Understand the gut-metabolic connection and its role in metabolic dysfunction, obesity, autoimmune conditions, allergies, mental health challenges, digestive disorders, and fatty liver disease.
Apply clinically validated frameworks to assess and restore gut ecosystem integrity using evidence-based, metabolic-focused approaches.
Integrate therapeutic carbohydrate restriction and other metabolic strategies into gut health interventions, grounded in current research and clinical best practice.
Identify and address root causes of gut dysfunction, moving beyond symptom management toward long-term metabolic restoration.
Implement practical tools, protocols, and case-based strategies to support gut repair in real-world clinical and coaching settings.
Interpret key gut-metabolic pathways with greater accuracy, for more informed decision-making and personalised intervention planning.
