EXCELLENT Based on 136 reviews Posted on John blicqTrustindex verifies that the original source of the review is Google. I worked with Jake on a structured nutrition plan with a clear target in mind. In 2 months, I dropped 7 kg—not through restriction or gimmicks, but through a plan we built together and that he held me accountable to consistently. What stands out is Jake's approach: he doesn't just hand you a meal plan and disappear. He maintains the discipline of the framework while staying responsive to what actually works for your life. That combination of structure and flexibility is rare. If you're serious about nutrition outcomes and need someone who will keep you honest while you do the work, Jake delivers.Posted on Mimo SsTrustindex verifies that the original source of the review is Google. I can’t thank Jake enough for all the help and support he’s given me on my weight loss journey. From the very first session, he made me feel completely comfortable and understood. He’s not just knowledgeable he’s genuinely caring, supportive, and always brings such a positive, bubbly energy to every conversation. Thanks to his guidance and encouragement, I’ve managed to lose 9.5kg in just 8 weeks! Highly recommend!!!Posted on Sid GirishTrustindex verifies that the original source of the review is Google. Jake is a master of his craft and specifically uses science-based knowledge for your particular nutrition goals. Over the past three months we’ve worked together on sustainable lean mass muscle growth. I’ve experienced steady, consistent, and incremental lean muscle mass gain without gaining unneccessary fat at the same time (the "dirty bulk" approach I had been using in the past) — This is exactly what I was looking for in a sustainable lean muscle mass growth journey. I've looked forward to our fortnightly one-on-one meetings where Jake’s thoughtful and insightful advice has always been carefully tailored to my individual needs. I have seen so much growth as I have put on 3kgs of pure muscle mass in the space of the last 3 months after we came up with an effective training and nutrition plan. Jake is a brilliant communicator and the continuous support he provides even outside of scheduled sessions has helped me tremendously. He’s been instrumental not just in helping me gain weight, but in guiding me to build a sustainable muscle growth plan that fits into my lifestyle long-term, including broader mental and physical strategies that go beyond just nutrition. If you're a male in Sydney looking for an expert in sustainable muscle growth who truly understands how to help you reach and maintain your target weight and cut through all the "industry" noise, then Jake is the one! I could not recommend his services more highly.Posted on Lily HTrustindex verifies that the original source of the review is Google. Jake is phenomenal. I had literally tried everything to lose weight and came to him highly skeptical it was even possible. Over 5 months I lost 9 kilos - no calorie counting, just steady, sustainable weight loss. Jake tailored a program for my specific needs that worked! His boundless enthusiasm and passion for what he does made it easy to stick to the program. He was always available for out of session support. I can not recommend Jake highly enough as an expert sustainable weight loss nutritionist- particularly to women who are struggling to make it happen themselves. My only regret is not finding Jake sooner!Posted on Matthew PowellTrustindex verifies that the original source of the review is Google. Jake offers a real science-based skillset for sustainable weight loss. I engaged his services to trim down a bit after not making much progress with customary calorie-counting. The goal was to lose weight ambitiously over a 2 month period. Jake’s method proved to be a bit too successful, having basically reached my goal weight in 3/4 of the time! Would recommend Jake to anyone who’s done with fad diets.Posted on Anthony DTrustindex verifies that the original source of the review is Google. Jake deserves the highest possible recommendation!

I had my initial consultation with Jake Biggs, and I couldn't be happier with the experience. He was extremely knowledgeable, professional and easy to talk to and took the time to listen to my specific goals and challenges. The advice he gave me for was incredibly insightful. I walked away feeling more informed about my nutrition plan and what I need to do next. If you're looking for a nutritionist who gives great, personalised advice, I highly recommend Jake!Posted on Julie & Greg ZieschangTrustindex verifies that the original source of the review is Google. I contacted Jake as I was looking for some guidance on healthy aging as I have a family history of vascular dementia and I was experiencing inflammation in my fingers, wrists and ankles. I am an active and fit 61 year old and I didn’t want to be restricted in any way. Jake offered realistic options that were backed by science. Whilst I can’t claim that I have reduced my risk of dementia, I can claim that the inflammation in my joints has reduced to the point that it no longer bothers me. Jake focused on modifying my diet and he definitely didn’t condone taking a multitude of supplements. It was all about healthy eating and the simple recipes he provided are now some of my staple favourites. Jake was always available via WhatsApp support, even after hours (usually because I had been googling some crazy “miracle” tablet or wanted a healthy protein ball recipe). As with everything, there is no quick fix but with time and healthy eating the changes were real. I can highly recommend Jake as a Clinical Nutritionist. He is passionate about improving his clients nutrition and health. He has the ability to cut through the nonsense and break complex nutrition information into understandable bite size pieces.Posted on Anne MynottTrustindex verifies that the original source of the review is Google.

Jake has supported me every step of the way with practical, sustainable advice tailored specifically to my goals.

If you’re looking for a nutritionist who truly understands sustainable weight loss and takes the time to care about your long-term success, Jake is the one. I can't thank him enough for everything he’s done, and I highly, highly recommend working with him.Posted on Thomas MynottTrustindex verifies that the original source of the review is Google.

As a sustainable weight loss nutritionist, I specialise in working with people who feel like they’ve tried absolutely everything to lose weight strict meal plans, fad diets, cutting carbs, endless cardio, even medications like Ozempic yet still find themselves stuck in the same frustrating cycle of losing weight, regaining it, and feeling like lasting results are impossible.
My mission is simple: to help you not only reach your goal weight, but to stay there for life. No more yo-yo dieting. No more restrictive food rules that leave you miserable. No more guilt for enjoying a meal out with friends. Instead, I teach you how to achieve effortless, sustainable weight loss that fits seamlessly into your lifestyle, without ever sacrificing your social life, energy, or joy.
Sustainable weight loss isn’t about perfection—it’s about consistency and compassion. No more chasing fad diets that burn you out. No more rigid plans that collapse the moment life gets busy. No more pressure to sacrifice foods you love. Instead, I help you build flexible, evidence-based habits that adapt to your lifestyle, so you can enjoy lasting results.
As a sports nutritionist, I also work with teenagers, adults, and aspiring athletes who want to unlock peak performance and fuel their bodies for success. From building lean muscle to maximising recovery and optimising competition performance, I design sport-specific nutrition plans that take the guesswork out of eating for performance.
I translate complex nutrition science into clear, practical strategies that fit seamlessly into everyday life. Whether it’s supporting growth and development in teenagers, helping adults balance training with busy schedules, or guiding aspiring athletes to reach the next level, I ensure every plan is evidence-based and personalised. This way, clients can fuel smarter, recover faster, and feel confident in their choices without unnecessary restriction.
Beyond the numbers, I emphasise education and empowerment—helping people understand why certain choices matter and how nutrition can be their competitive edge. By building confidence in food decisions and teaching flexible approaches, I remove the stress around eating for performance. The result is not just improved outcomes in the gym or on the field, but long-term resilience, health, and a positive relationship with food that supports success well into the future.
If you’ve been stuck trying diets, supplements, or strict meal plans and still feel like nothing works, you’re not alone. Most people end up confused, overwhelmed, and frustrated when it comes to their health. That’s where personalised nutrition makes all the difference.
