Specialist nutrition care for FODMAP treatment

FODMAP nutritionist Jake Biggs supports you in strengthening digestive function by restoring nourishment, identifying trigger foods and reducing gastrointestinal inflammation without restrictive dieting, rigid rules or unnecessary complexity.

Digestive Instability

Personalised FODMAP nutrition therapy to identify trigger foods, stabilise digestive rhythms and rebuild the nourishment your gut relies on for predictable, comfortable digestion.

Bloating & Distension

Targeted intervention to reduce bloating episodes, correct nutrient malabsorption and strengthen the biological systems required for long‑term digestive stability.

FODMAP Nutrition Care

Evidence‑based FODMAP guidance to calm the gut, reduce inflammation, improve tolerance, optimise absorption and create long‑term digestive stability for daily comfort.

Food Triggers & Energy Crashes

Structured FODMAP nutrition therapy to stabilise blood sugar, reduce gastrointestinal stress, improve digestive communication and rebuild the foundations of reliable gut function.

IBS & Gut Disorders

Comprehensive support to improve digestive tolerance, reduce symptom triggers, optimise nutrient absorption and strengthen the systems your body relies on for long‑term gut health.

Nutrient Deficiencies

Targeted nutrient correction to optimise iron, B‑vitamins, magnesium, omega‑3s and other key markers that influence digestive function, energy stability and symptom reduction.

Your nutrition impacts your FODMAP success.

Many people manage the daily frustrations of bloating, digestive instability and unexplained gut symptoms without ever addressing the underlying nutritional, metabolic and behavioural drivers. Food triggers, digestive inflammation and nutrient deficiencies silently erode energy, mood, digestive comfort and long‑term gut wellbeing.

Jake’s clinical approach begins with a deep assessment of your symptoms, medical history and eating patterns to uncover the root causes of your digestive dysregulation.

From there, he builds a personalised, evidence‑based FODMAP nutrition plan that restores digestive balance, stabilises gut rhythms and strengthens long‑term gastrointestinal outcomes and overall health.

Low iron, B‑vitamins or other key nutrients that quietly erode energy, mood and digestive resilience.

Abdominal Pain & Discomfort

Clinical FODMAP nutrition, done properly.

Every client of Jake’s goes through a structured clinical nutrition process, not a one‑size‑fits‑all protocol for FODMAP nutrition plans.

01

Deep-dive intake assessment

A thorough review of your full eating history, digestive patterns, medical background, current investigations and lived experience of gut symptoms. This is the foundation that everything else is built on.

02

Root cause identification

Rather than managing symptoms, Jake looks for the actual driver, whether that is micronutrient insufficiency, digestive inflammation or an undiagnosed food‑trigger pattern that keeps your gut compromised.

03

Personalised FODMAP nutrition plan

A customised FODMAP nutrition plan tailored to your specific nutritional needs and lifestyle, not a restrictive template but a liveable clinical strategy that supports long term digestive progress and daily wellbeing.

04

Your goals are the engine of your results

Jake and yourself will define your short and long‑term digestive goals, and the projections will be built with clinical precision to take you exactly where you need to go for optimal gut health outcomes.

05

Ongoing monitoring & expansion

Regular reviews to track progress, adjust your plan and expand dietary freedom. The goal is always the broadest possible diet that supports long‑term digestive progress, gut stability and daily wellbeing.

GUT HEALTH transformation

"I highly highly endorse Jake as a clinical nutritionist in Bondi Junction, Sydney that specialises in gut health. Jake has completely transformed my gut problems to now none! I came to see Jake as I was really struggling with my gut health. I was having chronic gut issues with bouts of irritable bowel syndrome that was problematic for myself. I had really tried everything but nothing was working for me. I am so glad that I met with Jake! From our first consultation together, I was incredibly impressed with his nutrition knowledge as well as his knowledge in everything related to the human gut. He explained to me exactly the changes that we need to make together and assured that my gut would be healed very quickly. Although skeptical at first, Jake was completely right. With the changes that Jake recommended for me, I now have a healthy gut. I don't have the problems that I had with irritable bowel syndrome. This is all thanks to Jake. Thank you so much. I highly recommend Jake Biggs as a speciality in the field of gut health as a clinical nutritionist."

"Jake Biggs is an outstanding clinical nutritionist and nutrition coach in Bondi Junction, Sydney. I can’t recommend Jake enough for all that he has done for me. I have been with Jake now for 9 months and the results have simply been phenomenal. I haven’t felt this energised for such a long time, and it is all thanks to Jake and the amazing work he has done for me. I was looking for a nutritionist or dietitian to help me improve my eating habits and overall health. I actually mentioned 9 months ago to a close friend of mine whether he knows or has seen a nutritionist before. Straight away without hesitation, in his words he said “You must see Jake Biggs in bondi junction”. Without flinching I contacted Jake and the rest is history. Jake provides such outstanding and detailed treatment plans that I feel privileged that he has worked with me. I haven’t felt this energised in years, I have had previously chronic gut issues and sleep problems. Jake in 9 Months has not only improved my gut and sleep but I now have no issues anymore with my gut and sleep. He has been simply outstanding for me and can’t thank him enough. Has totally transformed my health and well-being. Thanks again Jake".

No, you do not need a referral from your GP before seeing Jake for FODMAP support.

Many people come in with bloating, digestive instability, inconsistent eating patterns or no clear explanation for why their symptoms have developed.

Jake will conduct a thorough intake, review any existing investigations, and may recommend further testing where appropriate.

Jake’s approach is different because he doesn’t follow generic guidelines or symptom‑management templates.

A GP provides broad medical oversight and a dietitian often works within standard nutrition frameworks, but Jake focuses on what is actually driving your digestive challenges, not just what you are eating.

No, you will not be placed on a highly restricted diet. Jake’s approach is structured, personalised and clinically guided, but it is designed to be sustainable and flexible.

The goal is to rebuild nourishment and support long‑term digestive progress and gut stability while keeping your diet as broad and enjoyable as possible.

Most people actually gain more dietary freedom over time, not less.

Most clients begin meaningful digestive progress within the first few weeks.

Improvements often include better energy, more stable eating patterns, clearer focus and a stronger sense of structure around what their body and gut need.

Digestive and behavioural change evolves over time, but the habits that drive better regulation, consistency and daily wellbeing begin shifting almost immediately.

Jake monitors your progress closely and adjusts the plan so you continue moving forward with confidence.

Yes, Jake can work alongside your GP or Gastroenterologist.

A GP provides broad medical oversight and a Gastroenterologist manages diagnostic, structural and medical aspects of gut health, while Jake focuses on the nutritional, metabolic and behavioural drivers that influence your digestive symptoms.

Stop managing FODMAP symptoms. Start resolving them.

Jake combines world‑class expertise as a FODMAP nutritionist with extensive experience supporting people with digestive inflammation, gut instability, metabolic strain, fatigue and complex long‑term gastrointestinal‑health patterns. His approach gives clients a clear clinical advantage built on precision and measurable results.
