Jake works across the full spectrum of teenage nutrition needs each with a dedicated, evidence based nutrition approach.
Teen Nutrition Support
Personalised teenager nutrition therapy that targets low energy, mood swings, poor focus and inconsistent eating habits while supporting growth, stability and daily wellbeing.
Teen Nutrient Deficiencies
Clinical nutrition support for iron deficiency, low B12, inadequate protein intake and under‑fuelled patterns that often go unnoticed but significantly affect health.
Teen Nutrition Therapy
Expert guided nutrition therapy that identifies the real drivers behind your teenager’s symptoms. Evidence based strategies that improve energy, emotional regulation, learning capacity and overall health.
Teen Eating Pattern Assessment
Systematic identification of the patterns affecting your teenager’s nutrition including skipped meals, stress‑driven eating, under‑fuelled school days and inconsistent structure.
Teen Nutrition Challenges
Support for long standing issues such as fatigue, mood instability, poor appetite and irregular eating habits. Personalised nutrition therapy that restores balance and strengthens daily functioning.
Teen Symptom Mapping
Comprehensive assessment to map your teenager’s symptoms and uncover the nutritional, behavioural and lifestyle factors driving their struggles. Targeted nutrition therapy that builds long term wellbeing.
Teen health influences energy, mood, learning capacity, hormonal balance, confidence and overall wellbeing, yet many teenagers are left struggling for years without anyone addressing the underlying nutritional drivers.
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 teenager, not a generic protocol pulled from the internet.
Whether your teenager is newly struggling, has tried everything or simply feels “off” without clear answers, this is the level of teenager nutrition care that actually moves the needle.

Jake Biggs
Real clients, real gut health, real outcomes.
"After struggling with gut issues for 6 years and seeing countless doctors, Jake identified the root cause in our first session. Within 3 months I felt like a completely different person."
"I'd done the low FODMAP diet twice before and it never stuck. Jake's approach was completely different, he actually explained why I was reacting, and the reintroduction phase was life-changing."
"Living with Crohn's, I was terrified of food. Jake gave me the confidence to eat again, my flares have reduced dramatically and I haven't needed a hospital admission in 18 months."

You do not need a referral from your GP before seeing Jake, and families are welcome to book directly at any time. A referral can be helpful if you already have one or if your GP has completed recent investigations, but it is never required to begin care, and Jake will complete a full clinical intake regardless of whether a referral is provided.
Jake’s approach is different because he does not follow generic guidelines or symptom‑management pathways. A GP provides broad medical oversight and a dietitian often works within standard nutrition frameworks, but Jake focuses on what is actually driving your teenager’s challenges, not just what they are eating.
No, your teenager 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, stabilise energy, support mood and strengthen daily functioning while keeping their diet as broad and enjoyable as possible. Most teenagers actually gain more dietary freedom over time, not less.
Most teenagers begin noticing meaningful changes within the first few weeks, especially in energy, mood stability, focus and daily eating patterns. The deeper clinical shifts take longer and depend on their starting point, but the behavioural foundations that drive better attention, emotional regulation and overall stability start moving quickly once the right structure is in place. Jake monitors progress closely and adjusts the plan so your teenager continues moving forward with confidence.
Yes, Jake can work alongside your GP or gastroenterologist. A GP provides broad medical oversight and a gastroenterologist manages the diagnostic and medical aspects of IBS, while Jake focuses on the nutritional, behavioural and functional drivers behind your symptoms. Many clients work with both, especially when there are ongoing investigations, complex IBS symptoms or no explanation for why their gut has become unstable.
Jake combines world class expertise in teenager nutrition with extensive experience supporting both younger clients with emerging health challenges and older teens already managing long term patterns. His approach gives families a clear clinical advantage built on precision, science and measurable results.
