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 nutrition, and school wellbeing keynote speaking.

Whether you are aiming to achieve and maintain your goal weight, achieve peak performance, 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.

BHSc Nutrition & Dietetic Medicine (Honours)

One of the most rigorous nutrition qualifications available in Australia, covering clinical nutrition, dietetic medicine, sports nutrition, and evidence-based practice.

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. He translates complex nutrition science into practical, accessible advice that actually changes behaviour.

 Trustindex verifies that the original source of the review is Google. Jake has been incredible for me in my weight loss journey. 15kg lost in 4 months. Wow. I was lucky enough to be referred to Jake. Jake and I initially had a 30 minute call together. Having tried so many weight loss diets and continuing to rebound, I was stuck and felt nothing was working.

I was told that Jake is the weight loss nutritionist who helps women lose weight sustainably without any diets, calorie counting, diets and extreme amounts of exercise. I was sceptical how this could be. In our 30 minute initial call, I was amazed by Jake. He articulated beautifully on everything that I have done incorrectly and what we need to do to fix it.

I signed up straight away to Jake’s 4 month sustainable weight loss program and how lucky that I did. Jake went above and beyond for me. Not just the weekly check ins but so much more. Jake made for me 16 personalised weight loss seminars as well as weekly updated nutrition plans and exercise plans. I have never felt better, I am so educated now on weight loss.

I have just signed up to another 4 month program with Jake to lose my final 10kg. Jake is incredible. A weight loss nutritionist that not only gets incredible results but is so amazing to talk with to. Thank you Jake, Cant wait for another 4 months together.

 Trustindex verifies that the original source of the review is Google. Jake, I honestly don’t have enough words to thank you for all the progress I’ve made through your program!

I still remember the day I came to our first consultation feeling frustrated and with very little hope, as I hadn’t been able to lose weight for more than three years, even though I was exercising and had tried different diets.

After starting the program and setting clear and realistic goals, I began seeing amazing results. Jake gave me the right tools, motivation and guidance to understand how I should be eating and exercising to achieve my goals.

What I really loved about the program was that I never had to count calories, follow extreme diets or over-exercise. It was completely the opposite, it was about learning how to eat better, finding the right balance and adjusting my exercise according to what I wanted to achieve.

I’m incredibly grateful to Jake. He was always happy to listen, give advice and make adjustments whenever needed to keep me motivated throughout these four months. I’ve now lost 7 kilos, something that only a few months ago felt impossible!

More importantly, he helped me regain confidence in my body and feel proud and grateful for what I’m capable of achieving.

Thank you, Jake, for all the challenges, the good chats, and for always having the best attitude throughout this journey. I highly recommend Jake to anyone who is struggling to lose weight and wants to achieve their goals in a healthy, balanced and sustainable way.

Thank you so much!

 Trustindex verifies that the original source of the review is Google. I’ve had a fantastic experience working with Jake over the past two months and couldn’t recommend him more highly!

 Trustindex verifies that the original source of the review is Google. I consulted Jake to help manage my genetically high cholesterol and elevated blood sugar after being diagnosed with prediabetes in October last year.

During our very first consultation, Jake identified key health and lifestyle factors contributing to my high cholesterol and blood sugar. As a busy professional, I explained that I needed a sustainable approach that did not involve calorie counting, restrictive dieting, excessive exercise, or going hungry.

I purchased Jake’s 7-Week Essentials Program, and the results have been excellent. I have lost a significant amount of weight, my cholesterol has decreased, and I am no longer in the prediabetes range.

What I particularly appreciate about Jake is his ability to develop a practical, personalised, and sustainable nutrition strategy that fits into a busy professional lifestyle. His approach focuses on improving health without resorting to extreme measures.

I highly recommend Jake to anyone looking for an expert nutritionist who delivers meaningful, measurable results through sustainable lifestyle and dietary changes. My experience has been extremely positive, and I am very pleased with the progress I have made under his guidance.

 Trustindex verifies that the original source of the review is Google. I can't recommend Jake Biggs Nutrition highly enough. In just 3.5 months I lost 6kg without calorie counting or ever feeling starving — the approach was sustainable and genuinely fit into my life rather than fighting against it.
What sets Jake apart is his depth of knowledge. In a space full of influencers with no formal qualifications, Jake delivers real, evidence-based nutrition advice that actually changes your lifestyle for the long term, not just a quick fix.
He was incredibly supportive throughout, always available whether via WhatsApp or in person, and communicated clearly every step of the way. If you're looking for an expert who genuinely cares about your results, Jake is a standout choice.

 Trustindex verifies that the original source of the review is Google. I couldn’t recommend Jake enough. I lost 7.5kg in 8 weeks without calorie counting, restrictive dieting or constantly feeling hungry. His approach taught me how to make better choices while still eating normal foods I enjoy, which made the whole process feel realistic and sustainable. My performance in my sport was improving at the same time and that was a big goal for me.

Jake was also incredibly supportive and was basically available 24/7 whenever I had questions. I trusted his advice so much that when I got sick, he was actually the first person I messaged before I even spoke to my GP 😂.

I’m extremely happy with my results and feel like I’ve come away with the knowledge to maintain them long term. If you’re looking for a knowledgeable, supportive and trustworthy nutritionist who makes weight loss actually feel achievable, I’d highly recommend Jake

 Trustindex verifies that the original source of the review is Google. I started working with Jake 14 months ago and it’s been genuinely life-changing. I’ve lost 10kg without ever counting calories, restricting food groups, or forcing myself through extreme workouts; his approach is refreshingly simple: lean proteins about the size of my palm, the rest of the plate filled with veggies and fruit, and swapping sugary snacks for fruit instead of cutting anything out entirely. I was never left feeling hungry or deprived.

The results speak for themselves. My cholesterol, which was moderate-to-high, is now well within normal range, my sleep has improved, and I went from doing 2–3 CrossFit sessions a week to 5–6, purely because I finally had the energy and motivation for it. My clothes fit properly again and I’m noticeably fitter and healthier all round.

Beyond the physical changes, our fortnightly sessions were something I genuinely looked forward to, a great chance to talk through whatever was going on in my journey. Jake kept me accountable every step of the way.

I can’t recommend Jake highly enough as a weight loss nutritionist. If you want an approach that’s sustainable, healthy, and actually fits into real life, he’s your guy.

 Trustindex verifies that the original source of the review is Google. If you’re serious about making real changes in your life, Jake is the man for the job.

I came to Jake after hitting a rock bottom moment: I’d been underfuelling and completely mismatching my nutritional intake to my training output. Training 2-3 hours every morning on top of a full-time, demanding job, without the energy or nutrition to actually support it, left me underperforming and honestly, unbearable to be around.

Before working with Jake, I thought staying lean while training like a maniac could just… coexist. Over six months, he showed me that real progress isn’t about leanness, it’s about consistency and being able to keep doing the things I actually love and value.

Jake’s expertise is what sets him apart. In a world where everyone online has an opinion about nutrition, he cut through the noise and asked me the harder question first: what’s the actual goal here, what’s the point of all this training? Once I could answer that, he gave me the tools to build nutrition that worked for my life, not a generic template. He helped me stop seeing food as numbers on a label and start seeing it as fuel for what I’m actually trying to do.

After Six months working with, I’m a completely different person, genuinely better than I was before I started. I’d recommend Jake without hesitation to anyone serious about improving their performance the healthy, sustainable way. Best in the business.

 Trustindex verifies that the original source of the review is Google. Jake is an outstanding osteoporosis nutritionist. His expertise is clear from the first session, and he consistently delivers a high level of care and dedication both in and out of appointments.
What really sets Jake apart is his ability to break down complex information into simple, easy to understand guidance that you can actually use in everyday life. He makes the process feel approachable, supportive, and practical.
I would highly recommend Jake to anyone looking for expert, evidence-based osteoporosis nutrition support from someone who genuinely goes the extra mile.
Thank you for all of your help, Jake. It was greatly appreciated.

 Trustindex verifies that the original source of the review is Google. I spoke to Jake in relation to a nutrition plan aimed specifically at optimising my tennis performance. I found Jake approachable and that he was interested in what I was looking for. He answered all of my questions thoroughly  and in depth providing me with all the information I needed.

Jake’s level of knowledge with sports nutrition and his ability to convey and breakdown complex information for me to understand was exceptional. I feel confident with the knowledge I now have.

I would highly recommend Jake to anyone looking for a sports nutritionist!

The principles behind every consultation

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.

Personalisation over protocols

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

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.

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.

Clinical depth across multiple specialities

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

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.

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.

“Jake, you’re not going to wake up tomorrow”.

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 which was 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.
