  • Why gut health matters

Your gut is the foundation of IBD health.

The gut microbiome influences immune function, mental health, hormonal regulation, weight management, skin health and energy, yet IBD often leaves people managing symptoms for years rather than resolving the underlying drivers of inflammation.

Jake’s clinical approach starts with a thorough intake including current symptoms, health history, recent investigations, diet and lifestyle and builds a plan specific to your IBD presentation, not a generic protocol pulled from the internet.

Whether you are newly diagnosed, have tried everything or simply know something is off, this is the level of IBD nutrition care that actually moves the needle.

  • Recognise these?

Signs your gut needs clinical support

Chronic bloating

Daily bloating that does not resolve with dietary changes signals increased intestinal permeability.

Abdominal pain

Recurrent pain or cramping that disrupts meals, sleep or daily function indicates active leaky gut patterns.

Constipation cycles

Slow, incomplete or infrequent bowel movements that cycle unpredictably reflect impaired gut motility.

Explosive diarrhoea

Sudden, urgent or watery stools point to gut lining irritation, increased intestinal permeability.

Post‑meal discomfort

Pain within minutes of eating suggests irritation of the gut lining and heightened sensitivity associated with active leaky gut.

Food intolerance expansion

A growing list of foods causing symptoms indicates worsening gut barrier permeability.

Unpredictable flare cycles

Symptoms that spike without clear triggers show unstable gut regulation driven by gut lining irritation.

Self-management failure

When supplements, diet changes or online protocols fail, it reflects deeper gut‑lining dysfunction.

  • Jake's approach

Clinical IBD nutrition, done properly.

Every IBD client goes through a structured, clinical process, not a one‑size‑fits‑all protocol.

01

Deep-dive intake assessment

A thorough review of your full IBD symptom history, health timeline, current investigations, medications and diet. This is the foundation everything else is built on.

02

Root cause identification

Rather than managing symptoms, Jake looks for the actual driver, whether that is enzyme insufficiency, immune‑mediated inflammation, motility dysfunction or an IBD‑related trigger pattern.

03

Personalised IBD nutrition plan

A structured eating plan tailored to your specific IBD presentation, food preferences and budget, not a restrictive template but a liveable clinical strategy.

04

Your goals are the engine of your results

Jake and yourself will define your short and long‑term IBD goals, and the projections will be built with clinical precision to take you exactly where you want to go.

05

Ongoing monitoring & expansion

Regular reviews to track progress, reintroduce foods and expand dietary freedom, the goal is always the broadest possible IBD diet that keeps you well.

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".

Do I need a diagnosis before seeing Jake for IBD?

No, you do not need a formal food intolerance diagnosis to book. Many clients come in with bloating, abdominal discomfort, irregular bowel habits or unresolved digestive symptoms without a clear label. Jake will conduct a thorough intake, review any existing investigations and may recommend further testing where appropriate. A diagnosis helps, but it is not required to get started.

A gastroenterologist manages the medical and diagnostic aspects of gut health, while Jake builds a personalised nutrition strategy that restores gut function, reduces inflammation and stabilises daily food intolerance symptoms. They work differently, and many clients choose to work with both for the most complete care.

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 support gut function, calm inflammation and stabilise IBD symptoms while keeping your diet as broad and enjoyable as possible. Most clients actually gain more dietary freedom over time, not less.

Most clients begin noticing meaningful changes within the first few weeks. Improvements often include better energy, more stable digestion, reduced bloating and clearer structure around what their gut needs. Progress itself evolves over time, but the behaviours that calm inflammation, stabilise gut function and reduce IBD symptom flares begin shifting almost immediately. Jake monitors your progress closely and adjusts your 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.
