Weight Loss
Long term weight loss does not exist without the right strategy: Most people are stuck in the cycle of losing weight, regaining it, then starting again. Without a sustainable, clinically designed approach, long term weight loss is impossible.
Sports Nutrition
Teenagers and adults consistently underperform because their nutrition does not match their training load, growth demands or recovery needs. Performance potential is significantly reduced when nutrition is not personalised and precise.
Clinical Nutrition
Your health goals move further away with generic diets: Medical conditions do not improve with guesswork. Generic diets and one size fits all plans push your health goals further out of reach. Without targeted clinical nutrition, progress becomes slower and harder.
Jake Biggs

100s of clients have achieved & maintained their goal weight, achieved elite sports performance and achieved optimal health.
EXCELLENT Based on 140 reviews Posted on Google G HTrustindex verifies that the original source of the review is Google. I needed help. My weight had plateaued and I was stuck and desperate. My specialist told me I had to find a nutritionist to get me back on track. My daughter did some research and found Jake of Nutrition Longevity. She told me he had the best reviews she’d’ found. The rest is history. Jake helped me to focus on what needed to be done if I was to successfully reach my goal weight. I did what he told me and as long as I did that I had a consistent weekly weight loss. I didn’t count a calorie! I had such a sense of freedom. In 8 weeks I’d lost more than 4kgs. The process continues and I am loving it. Because of what he has taught me I believe I will get to my goal weight and this time NOT regain the weight I lose! Jake is very knowledgeable about nutrition and patient when explaining concepts around it. He has been very encouraging along the way. I’m most grateful. Thanks again Jake!Posted on Google Makayla CraggTrustindex verifies that the original source of the review is Google. Jake has a wealth of knowledge that has really helped me understand sport nutrition. I have been looking at different supplementation for elite sport and Jake has provided great guidance on the benefits and risks of the supplements. He has explained in great detail using his sport nutrition expertise and significantly helped me with understanding how I can benefit myself through sport and be careful surrounding different nutrition strategies. I would definitely recommend him as he is calm, friendly and is extremely helpful through his knowledge.Posted on Google Natalia HenríquezTrustindex verifies that the original source of the review is Google. I decided to work with a dietitian after having my baby, as I was struggling to lose weight through the gym. I chose Jake because he individualized his assessments based on size, which I appreciated—I didn’t want to focus on the number on the scale. The weekly check-ins helped me stay aware of my habits, and Jake’s human approach connected my emotions and experiences with my food choices. What I liked most was that I never felt like I was on a strict diet; it was more holistic and personal. Although I did have to cut out some foods initially, I never felt deprived. In fact, I had more energy because I was eating better nutrients. As a working mom with a small baby and dogs, the plan was tailored to what I had available, making it easy to follow. Jake encouraged me to choose my own foods and offered alternatives, which empowered me to make my own decisions about what to eat. Overall, this plan significantly boosted my self-esteem, and I was able to return to my pre-pregnancy weight in just four months—without any stretch marks and feeling revitalized. I am truly grateful for the support I received and found it easy to communicate with Jake. His approach was very personable, and I consider working with him to be one of my best investments post-pregnancy. I highly recommend him.Posted on Google Ben KramerTrustindex verifies that the original source of the review is Google. Jake was an incredible person to work with, who genuinely cares about all his clients and goes above and beyond to make sure they hit their personal goals.Posted on Google Lisa HTrustindex verifies that the original source of the review is Google. Thanks so much, Jake! This was my first time ever seeing a nutritionist, and you made the whole experience feel easy and approachable from the start. I really appreciated how well you understood me and helped tailor my eating to suit my busy lifestyle and personality. I’m so happy with where I’m at now, and you’ve made everything feel sustainable long term. Thank you also for all the support outside of sessions — answering questions and helping me find specific products at the supermarket made such a difference. I feel like I’m at a healthy weight again and finally feel great in my clothes again. I couldn’t recommend Jake more!Posted on Google 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 Google 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 Google 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 Google 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 Google 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.
