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
Elite sports performance is not achieved by how hard you train, how fit you are, how talented you are, or how good your genetics may be. For both teenagers and adults, peak performance is only possible with customised sports nutrition plans for your desired sport.
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.

EXCELLENT Based on 143 reviews Posted on Google Wayne KeyserTrustindex 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.Posted on Google Ben HondrosTrustindex 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.Posted on Google Simone McPhersonTrustindex 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.Posted on Google Scarlett ShermanTrustindex 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!Posted on Google CharlotteTrustindex verifies that the original source of the review is Google. Jake is outstanding. Jake has been a absolute breath of fresh air for me. I have no hesitation of recommending Jake to everyone! Jake has a wealth of knowledge in weight loss that I haven't ever experienced or heard about before. He is an incredible weight loss nutritionist. I reached out to Jake as I felt absolutely helpless. I had tried so many diets and online programs, was on the verge of giving up and I decided to give the clinical route a go and how glad i was that I did. In the initial consultation with Jake he outlined exactly what we need to do together over the next 6 months to achieve and maintain my goal weight. As a busy mum, I thought this was impossible. But with Jake's help I did and never felt deprived along the way. His constant support, encouragement and motivation was literally life changing for me. I highly recommend Jake as a weight loss nutritionist, he is amazing. Thanks so much Jake. Charlotte.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!
