Jake works across the full spectrum of gut and digestive conditions, each with a dedicated, evidence-based nutrition approach.
Irritable Bowel Syndrome (IBS)
Personalised dietary therapy for IBS-C, IBS-D, and IBS-M: including low FODMAP guidance, gut-brain axis strategies, and lifestyle integration.
SIBO (Small Intestinal Bacterial Overgrowth)
Targeted nutrition protocols for hydrogen, methane, and hydrogen sulphide SIBO, working alongside your treating practitioner for full resolution.
Low FODMAP Diet
Expert-guided implementation of the 3-phase Monash University low FODMAP protocol: elimination, reintroduction, and personalisation without unnecessary long-term restriction.
Leaky Gut (Intestinal Permeability)
Repair the gut lining and reduce systemic inflammation with a targeted nutrition and supplement protocol: addressing the root driver behind many complex, multi-system symptoms.
IBD: Crohn’s & Colitis
Medical nutrition therapy to reduce flare frequency, support remission, correct nutritional deficiencies, and improve quality of life alongside your gastroenterologist.
Food Intolerances & Sensitivities
Systematic identification of food triggers, lactose, fructose, gluten sensitivity, histamine – with a management plan that broadens your diet over time, not narrows it.
The gut microbiome influences immune function, mental health, hormonal regulation, weight management, skin health, and energy: yet most people spend years managing symptoms rather than resolving the underlying cause.
Jake’s clinical approach starts with a thorough intake, current symptoms, health history, recent investigations, diet and lifestyle, and builds a plan specific to your gut, not a generic protocol pulled from the internet.

No, you don’t need a formal diagnosis to book. Many clients come in with unresolved symptoms and no clear label.
Jake will conduct a thorough intake, review any existing investigations, and may recommend further testing where needed. A diagnosis helps, but it’s not required to get started.
Jake’s approach is different because a gastroenterologist focuses on diagnosing and treating disease, while Jake focuses on identifying the underlying nutritional and lifestyle drivers of your symptoms and creating a personalised gut health nutrition plan that restores gut function and daily comfort.
No. You will not be placed on a highly restricted diet for gut health. Jake’s clients gain more dietary freedom over time as their gut function improves, inflammation settles and tolerance to foods increases.
His approach focuses on rebuilding the gut, supporting digestion and restoring comfort rather than removing large food groups or creating unnecessary restriction.
Most clients begin noticing meaningful changes within the first few weeks.
You can expect early improvements in digestion, comfort, bloating, bowel regularity and overall gut function as your plan begins correcting the underlying drivers of your symptoms.
The exact timeline depends on your physiology, symptom severity and consistency, but Jake will map out your personalised projections after your initial consultation so you know exactly what progress looks like for you.
Yes. Jake works seamlessly alongside your GP or gastroenterologist.
Your GP provides overall medical oversight and your gastroenterologist manages diagnostic and medical aspects of gut health, while Jake focuses on the nutritional and functional drivers behind your symptoms.
This collaborative approach ensures your medical care and nutrition strategy move in the same direction with complete clarity.
Jake combines world‑class experience as a gut health nutritionist with a truly global perspective. His work spans chronic bloating, SIBO, IBS, food intolerances and complex digestive dysfunction, allowing him to identify patterns and root causes that many practitioners overlook.
Every assessment is grounded in evidence, every recommendation is personalised and every strategy is designed to create long‑term, measurable change in the way your gut functions. This is the level of expertise clients seek when they want results that last.
