Meet Jake Biggs.

Jake is Sydney’s leading accredited clinical nutritionist, sports nutritionist and weight loss nutritionist, and one of the few practitioners who has genuinely lived what he teaches. His approach is evidence-based, relentlessly results-driven, and built on a depth of lived experience that no textbook can replicate.

Nutrition that actually fits your life

Most people come to Jake after trying everything else. Fad diets, generic meal plans, advice that worked for someone else but never quite worked for them.

Jake’s approach is different from the first consultation. He starts with a comprehensive clinical assessment, not a questionnaire. He then builds a customised plan exclusively for your body, lifestyle, health history, and goals.

There’s no template. No guesswork. Just a precise, personalised strategy and the ongoing support to make it stick.

Not your typical nutritionist.

Jake specialises in sustainable weight loss, sports nutrition, clinical nutrition, corporate, and school wellbeing keynote speaking.

Whether you are aiming to achieve and maintain your goal weight, achieve peak perforformance, managing a health condition or simply wanting to feel better in your own body, Jake’s plans are built exclusively for you, not a generic template.

What sets Jake apart isn’t just his qualifications. It’s the fact that he has been through it himself.

After surviving severe anorexia nervosa and a Grade 3 brain tumour, he rebuilt his health from the ground up using the same evidence-based principles he now applies with every client.

Clinical, sports and weight loss nutritionist, all in one

Most nutritionists specialise in one area. Jake practises across clinical nutrition, sports performance, and sustainable weight loss, giving you a complete picture, not a narrow one.

Keynote speaker and recognised Sydney nutrition expert

Jake speaks at schools, corporates, and conferences across Australia, translating complex nutrition science into practical, accessible advice that actually changes behaviour.

The principles behind every consult

01

Evidence, not trends

Every recommendation Jake makes is grounded in evidence based research. No fads, no shortcuts, no advice that sounds good but doesn’t hold up.

02

Personalisation over protocols

Jake doesn’t believe in generic meal plans or templates. It never works. Jake develops a customised plan exclusively for you. 

03

Results that last

Quick fixes aren’t the goal. Jake’s plans are designed to build habits and understanding that sustain your results long after your last session.

You don’t have to keep guessing. Evidence-based help is one conversation away.

What makes Jake different

There are a lot of nutritionists in Sydney. Here’s what sets Jake apart.

01

Lived experience, not just clinical training

Jake survived severe anorexia nervosa and a Grade 3 brain tumour. He rebuilt his health from scratch. That lived experience gives him an understanding of the relationship between food, body, and mind that goes well beyond what any degree can teach.

02

Clinical depth across multiple specialities

Jake practises across clinical nutrition, sports nutrition, and weight loss: meaning your plan accounts for all of you, not just one dimension of your health.

03

Support between sessions, not just during them

Jake’s clients have access to unlimited text message support during consultations. Questions get answered. Adjustments get made. You’re never left to figure it out alone.

04

In-person and Telehealth, Australia-wide and globally

Jake sees clients in person at his Bondi Junction private practice and via Telehealth across Australia and globally, so wherever you are, the same quality of care is available to you.

The journey that changed everything

At 15, Jake developed severe anorexia nervosa. Over the following decade, his condition became life-threatening requiring 20 hospital admissions and leaving him facing the very real possibility of death on multiple occasions.

During one of the most extreme episodes, after going without food for seven days, his heart rate dropped to just 25 beats per minute. His doctors told his family there was a real chance his heart could stop overnight. That night, Jake remembers thinking those words with complete clarity.

He did wake up. And that survival became the turning point. What followed was a long, hard, and deeply personal process of rebuilding, not just physically, but neurologically, hormonally, and psychologically.

Later, Jake faced a second challenge: a Grade 3 Frontal Lobe Astrocytoma brain tumour. Again, he rebuilt. Through both experiences, he developed a firsthand understanding of what the body needs to heal, adapt, and perform that no textbook could have given him.
