ACCREDITED CLINICAL NUTRITIONIST, SPORTS NUTRITIONIST: BONDI JUNCTION, SYDNEY & ONLINE
Optimal gut health can only be achieved with the guidance of an expert FODMAP nutritionist in Sydney.
Are you constantly struggling with abdominal pain, bloating, constipation, diarrhoea, flatulence, acid reflux, or unpredictable bowel movements? Do you experience nausea, food intolerances, heartburn, stomach cramps, or post-meal fatigue that leaves you anxious about eating or socialising? Are you frustrated by brain fog, low energy, mood swings, skin issues, or disrupted sleep — all linked to your gut?
Maybe you’ve been told it’s “just IBS,” “stress,” or “normal,” leaving you stuck in a cycle of restrictive diets, confusing food lists, and trial-and-error remedies. Have you tried the low FODMAP diet without clarity, structure, or lasting results? These symptoms are not something you should have to tolerate — and you don’t have to.
I’m Jake Biggs, a FODMAP nutritionist in Sydney specialising in the treatment of IBS and complex digestive issues. I use advanced microbiome testing and evidence-based, personalised FODMAPS protocols to identify your unique triggers and restore gut function.
I help you navigate the low FODMAP diet with precision, reduce inflammation, regulate bowel movements, improve nutrient absorption, and reclaim your energy, focus, and confidence. From bloating and food intolerances to IBS, SIBO, and post-infectious gut issues, I provide expert guidance so your digestion works the way it should — transforming your mood, immunity, and quality of life. Stop guessing and start healing — your gut deserves expert FODMAP care.
This isn’t your standard nutrition consultation with a dietitian or nutritionist. This is a detailed, evidence-based FODMAP nutrition consultation designed specifically for individuals and families navigating IBS, bloating, food intolerances, and digestive distress.
First 45 Minutes – Comprehensive FODMAP Assessment & Functional Gut Analysis: We begin with a detailed evaluation of your dietary intake, supplement use, and hydration practices, with a specific focus on FODMAP exposure and symptom correlation. This includes a thorough assessment of macronutrient and micronutrient status, as well as identification of dietary patterns that may be contributing to gastrointestinal disturbances, nutrient malabsorption, or systemic inflammation.
A structured review of lifestyle factors—including stress, sleep quality, physical activity, and daily routines—helps us understand their impact on digestive function, microbiome balance, and overall gut resilience. This comprehensive analysis enables precise identification of the underlying drivers of symptoms such as bloating, constipation, diarrhoea, and food sensitivities.
Final 15 Minutes – Personalised FODMAP Nutrition Plan for Gut Optimisation: Based on your assessment, I deliver a clinically tailored, evidence-based blueprint to optimise gut function long-term. This plan integrates low and moderate FODMAP mapping, microbiome support, and targeted lifestyle strategies to restore digestive balance, reduce inflammation, and improve nutrient absorption.
You’ll receive precise guidance on meal structuring, nutrient timing, supplementation, and lifestyle modifications tailored to your unique physiology and symptom profile. This blueprint goes beyond symptom relief—it provides a sustainable framework to support digestive efficiency, energy, immune function, and overall wellbeing. You’ll leave with clarity, confidence, and a step-by-step strategy to optimise your gut health for life.

As a FODMAP nutritionist, I don’t just manage symptoms — I work with you to uncover the root causes of your digestive distress, whether it’s bloating, constipation, diarrhoea, food sensitivities, or chronic inflammation. Through advanced assessment and FODMAP-specific analysis, I create personalised, evidence-based nutrition and lifestyle strategies designed to restore gut balance, optimise nutrient absorption, and support a resilient microbiome.
My approach helps you regain control over your digestion, reduce discomfort, improve energy levels, strengthen immunity, and enhance overall wellbeing — without relying on restrictive guesswork or generic advice.
By identifying and addressing the underlying drivers of your gut dysfunction, you can finally stop fearing food, reduce flare-ups, and enjoy sustainable, long-term improvements. Your gut should support how you live, eat, and feel — not control it.
| Your Current Situation | Optimal FODMAPS Nutrition with Myself |
|---|---|
| Confusion around which foods are high or low in FODMAPs, leading to inconsistent symptom control and fear of eating. | I provide clinically accurate, phase-specific food lists and teach you how to interpret FODMAP content across categories (fructans, GOS, lactose, excess fructose, polyols). You’ll learn how to read labels, assess portion thresholds, and build confidence in food selection. |
| Persistent bloating, gas, and abdominal pain after meals despite following a “low FODMAP” diet. | I assess your symptom timing, food combinations, and microbiome status to identify overlooked FODMAP sources, layering effects, and co-factors like stress or enzyme insufficiency. I then restructure meals and support digestion with targeted interventions. |
| Constipation, diarrhoea, or alternating bowel patterns that disrupt daily life and reduce quality of life. | I modulate fibre types (soluble vs insoluble), adjust hydration and electrolyte intake, and tailor FODMAP exposure to support motility. I also address gut-brain axis factors and microbial imbalances that influence bowel regularity. |
| Difficulty reintroducing foods without triggering flare-ups, leading to long-term restriction and nutritional gaps. | I guide you through a structured reintroduction protocol using symptom tracking, portion calibration, and microbiome support. This expands your food variety while maintaining digestive comfort and nutritional adequacy. |
| Over-reliance on generic FODMAP apps or online lists that don’t reflect your unique physiology or symptom profile. | I deliver personalised guidance based on your clinical history, microbiome testing, and symptom mapping. My approach goes beyond static lists to address real-world food combinations, timing, and tolerance thresholds. |
| Fear of eating out, travelling, or socialising due to unpredictable digestive reactions. | I help you build flexible, FODMAP-aware strategies for dining out, travel, and social events. You’ll learn how to navigate menus, communicate dietary needs, and manage symptoms discreetly and confidently. |
| Fatigue, brain fog, and low mood linked to poor nutrient absorption and gut inflammation. | I restore energy and cognitive clarity by improving digestive efficiency, stabilising blood sugar, and supporting the gut-brain axis with targeted micronutrients and anti-inflammatory FODMAP-safe foods. |
| Coexisting conditions like SIBO, IBD, or histamine intolerance complicating FODMAP management. | I integrate FODMAP protocols with broader clinical strategies to address overlapping conditions. This includes antimicrobial support, histamine modulation, and anti-inflammatory nutrition tailored to your diagnosis. |
| Long-term restriction leading to microbial depletion and reduced digestive resilience. | I help you rebuild microbial diversity through phased reintroduction, prebiotic support, and strategic use of fermentable fibres that are well tolerated. This strengthens gut resilience and long-term health. |
| Uncertainty about how FODMAPs interact with stress, sleep, and lifestyle factors. | I assess your circadian rhythm, stress response, and daily routines to identify non-food contributors to digestive symptoms. I then integrate lifestyle strategies that support gut healing and symptom stability. |
As your dedicated FODMAP nutritionist, my role goes far beyond providing a generic low FODMAP food list. I deliver precision-engineered FODMAP nutrition strategies tailored to your digestive profile — designed to make every meal symptom-aware, structured, and reliable while fully aligned with your lifestyle, preferences, and clinical needs.
My approach focuses on the critical pillars of digestive health: identifying and managing FODMAP triggers, restoring microbial balance, and optimising nutrient absorption. Whether it’s daily meals, symptom tracking, or phased food reintroduction, your nutrition becomes a seamless tool for digestive comfort, energy, and confidence — fully personalised to your physiology and long-term gut health goals.
