The problem isn't your willpower.

01

Generic meal plans and diets are not customised

They overlook your body and your life, pushing you into a weight loss approach that was never made for you. 

02

Restriction triggers the weight rebound cycle

It pushes your body into survival mode, ramps up weight gain rebound, and locks you into the same dieting cycle you’ve been trying to escape.

03

The real weight gain drivers stay unaddressed

The real reasons you can’t lose or keep weight off remain completely unaddressed meaning you never fix the real weight problem.

There’s a better way, one that works with your body, not against it.

Daniel
"The best weight loss nutritionist is quite simply Jake! Thanks so much Jake for enabling me to sustainably lose weight over the last 6 months and I feel better than ever. After trying so hard for many years to lose weight and keep it off on the verge of totally giving up, I was recommended Jake. How lucky was I. With Jake I have been able to lose 23kg and I have lost it with Jake without being hungry. Jake put together for me an initial sustainable weight loss nutrition plan and continued to tweak over time. What makes Jake so good is not just his expertise but he is such a caring guy as well. If I needed to reach out to him, Jake was always there. Supporting me every step of the way. It didn't feel like a diet with Jake, he is truly amazing. I can only say that if anyone is looking for an expert and caring weight loss nutritionist, Jake is the perfect answer for you".
Jack
"Best sustainable weight loss nutritionist in Sydney. Jake is a phenomenal weight loss nutritionist. His approach is fantastic. Since working with Jake I have lost weight sustainably twenty kilograms and I feel amazing. His weight loss approach is great. Slow steady reductions in food and healthy amounts of exercise. I can only highly recommend Jake as a weight loss nutritionist for anyone looking to lose weight sustainably and keep it off. He has been a game changer for me. Thanks so much Jake".
Lily
"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!".
Anthony
"Jake deserves the highest possible recommendation! Over the nine months we’ve worked together, I’ve experienced steady, consistent, and incremental weight loss — exactly what I was looking for in a sustainable weight loss 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. What really sets Jake apart is his brilliant communication and the continuous support he provides even outside of scheduled sessions. He’s been instrumental not just in helping me lose weight, but in guiding me to build a sustainable weight loss plan that fits into my lifestyle long-term, including broader holistic strategies that go beyond just food. If you're a male in Sydney looking for an expert in sustainable weight loss who truly understands how to help you reach and maintain your target weight, Jake is the one. I could not recommend him more highly".
Charlotte
"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".
Anthony
"I can only say wonderful words about Jake Biggs as an expert weight loss nutritionist. I have seen Jake for 2.5 months now and my weight loss and fat loss results have been absolutely incredible. I am so grateful that I got in touch with Jake. Jake’s expert weight loss treatment plans have impressed me so much. I have also found Jake highly personable, funny and engaging. He really listens to me with the consultations that I have with him and provides me personalised videos after each consultation that we have together. He has made the weight loss process seamless and this is all thanks to Jake. I have also found even with me continuing to lose weight with Jake that my energy levels are still fantastic and I am not feeling hungry all the time which I thought would happen. Jake’s sustainable weight loss approach is very refreshing and with Jake I have already lost 6kg and lost nearly 10cm off my waist and hips in only 2.5 months with working with Jake on my weight loss. I have thoroughly enjoyed my time with Jake and the consultations we have together. He has really empowered me with my decision making towards food choices. I am very lucky that I came across Jake and am excited to continue working with him to reach my goal weight. With Jake it is not just about a diet. It is much more than that. He looks meticulously at your exercise, sleep, stress management as well as food intake. I can say that if anyone wants a weight loss nutritionist, Jake is the perfect one for you. His approach is fantastic and I can only thank Jake for all his work he has done for me! I highly highly recommend Jake Biggs as a weight loss nutritionist".
Hiyes
"Jake is a phenomenal weight loss nutritionist in Sydney. If anyone is looking for a sustainable weight loss nutritionist, Jake is the only nutritionist you should go to. His weight loss nutrition plans are amazing and I have benefitted so much from. I have been able to easily lose weight with following Jake’s expert guidance and I haven’t felt hungry at all! Thanks so much Jake. Jake has always supported me outside of consultations as well with always checking up on me. He is a great caring guy too. Can only say incredible words about Jake as a weight loss nutritionist. He has been a game changer for me and would highly endorse Jake to anyone who is looking to lose weight sustainably.

Anna
"I highly highly recommend Jake as a weight loss nutritionist in Bondi Junction, Sydney. Jake has really changed my life and I am so grateful that i got referred to Jake. He is simply an incredible person and amazing weight loss nutritionist. I have seen Jake now for 10 months and the results have been phenomenal. Really, beyond my wildest dreams. I have with Jake's expert help managed to lose 20kg. Jake is so personal and his treatment plans are incredible. Thank you so much Jake. Highly recommend".
Julien
I’ve been seeing Jake since August, and so far, I’ve lost 14 kilos, and I am still losing. From the start, I was stubborn, especially regarding exercise. I resisted the idea altogether, but Jake had the patience and expertise to guide me without pressure, allowing me to make changes at my own pace. His approach is not about strict diets or unrealistic expectations but about sustainable, real-life solutions that work. The results speak for themselves! I’m feeling better, healthier, and more in control of my habits. If you’re looking for a nutritionist who truly listens, adapts to your needs, and delivers actual, long-term results, I can’t recommend him highly enough. Thank you, Jake, for your support and dedication!".
Mimo
"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!!!".
John
"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".
Gillian
"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 had 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!".
Ralene
"Jake is exceptional. First time that I have easily dropped the weight effortlessly. His approach, style and enthusiasm is infectious. 11/10 Jake. I’m always away and two months in and I’m 7 kilos down!!".
Keira
"I came to Jake 2 years post a twin pregnancy wanting to loose weight for my upcoming wedding he was nothing but motivational I couldn’t have lost the 10kg without him!! Thank you Jake".
Linda
"I was referred to Jake in August 2023. We had an initial chat on the phone as I wanted to see what Jake was offering and how much experience he had. From the outset he was very willing to listen and discuss things with me. Having struggled with menopausal weight gain for the past 2 years and realising that nothing I was doing was helping, I decided to join up with Jake and see what would transpire. He was very skilled in listening to my exercise history and food diary and then writing a phenomenal meal plan. What makes this even better than any other dietician i have ever seen is that Jake nailed perfectly the exact amount of food that i required each day and DID NOT LEAVE ME FEELING HUNGRY!!!!! Jake, that in itself is just amazing. As a fitness professional with a very active lifestyle it is so important that I keep up my energy reserves for this life I live. Jake gives ongoing support, checks in to make sure all is well, follows each weigh in day, gives SO MUCH encouragement and is truly invested in his clients. If I have any questions I only need to shoot him an email and he will answer it. The weight loss has been amazing - down 8kgs in 3 months and still going. I would highly recommend Nutrition Longevity with Jake Biggs, especially if you have reached Menopause and are struggling to lose weight. THANK YOU, Jake! I recommend you to everyone. You certainly have proven yourself to be very skilled at prescribing correct nutrition and food requirements. I look forward to continuing this journey with you in 2024".
Keith
"Jake assisted me to move from 108 kg to 105 kg in the space of 2 months. He did this holistically by taking account of my preferences (vegetarian) and describing a diet that worked for me. My weight loss was gradual and consistent, and has continued since I last saw him a month ago (despite a few small and tasty distractions in that time). His approach is caring, considerate and focused on the slow and effective style of weight loss. I would recommend Jake to any person seeking to reduce their weight".
Marco
"I can't thank Jake enough for transforming my approach to nutrition and weight loss. Before finding him, I had tried countless diets and methods without success. Under his guidance, I've achieved what seemed impossible, losing 8kg, and I'm especially grateful for the nutritional education he provided. His consistent support kept me motivated throughout my journey, which made all the difference in maintaining my progress. If you're looking for a nutritionist who combines expertise with genuine care and support, Jake is your answer".
Michael
"Where to start with Jake. I saw Jake for 9 months and lost over 10kg of fat and put a stack of muscle on. He is so much more than just writing out a diet plan and saying go for it. He works out with you exactly what you need and is accepting about the ways in which you struggle with sticking to the plan. He makes adjustments that'll lead to your success and covers across many factors relating to health than just simply food. I thoroughly enjoyed my time working with Jake and would recommend him to anyone that is seeking out a nutritionist".
Jeca
"I can highly recommend Jake as an excellent weight loss nutritionist. In just 6 months I have achieved all my goals and could not be happier. This has been achieved due to Jake’s weight loss expertise and continuous support, even outside our sessions. My plan was simple and easy to implement and fitted well into my lifestyle. Thanks to Jake I’m feeling fit and healthy, and can highly recommend his approach".
Elizabeth
"I am a post menopausal woman who was referred to Jake by a doctor to shift some stubborn weight. I've done plenty of diets in the past and was quite sceptical at first that he couldn't teach me anything new. I'm also a person who loves to cook and eat gourmet food and I didn't want to be hungry. Over the last 10 weeks I've lost 6kg. I'm proud of myself for what I've been able to achieve. However, I got there through Jake's guidance and coaching. There were things I didn't know and Jake was able to educate me in many areas. I think the really important thing is not the initial weight lost but how to lose weight in a sustainable way and to know how to keep the weight off".
Jakub
"I have worked with Jake for 11 months now and we have achieved extraordinary results together. I lost a total of 12.5kg with Jake and then put on 4.3kg of muscle afterwards. Jake was able to educate me very much on sports nutrition for my body composition goals. He was always there for me when I needed to contact him. Very supportive and knowledgeable as a sports nutritionist. I highly recommend Jake as a sports nutritionist and weight loss nutritionist in Sydney".
Linzi
"Ive been working with Jake for about 6 weeks now. Ive lost weight in terms of Kgs and CM. I have more energy and im no longer taking a concoction of vitamins to support my health- winner. Jake is also kind and non judgemental. He's super supportive and will explain the science behind nutrition in an easy to understand way".
Matthew
"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".

How is this different from just following a diet?

A diet is a generic set of rules. Jake’s approach is a personalised clinical strategy built around your body, your lifestyle, your preferences and your schedule.

No two plans are the same because no two people have the same history, challenges or goals.

This level of individualisation is why Jake’s clients progress with clarity and consistency, even when every diet or program they have tried in the past has failed them.

No. You will not have to count calories or weigh food.

Jake uses a structured, predictable approach that teaches you how to build meals, regulate hunger, and stay consistent without tracking apps or measuring every bite.

The goal is to make eating feel easier, not more complicated, so you can lose weight in a way that fits your lifestyle and lasts long term.

Clients begin seeing clear, measurable weight loss within the first few weeks once their eating patterns, appetite, exercise, sleep and daily structure are stabilised.

The exact pace depends on your starting point, routine, history with weight loss, exercise levels, hormones, stress load and consistency.

The focus is steady, predictable progress that lasts rather than the fast drop and rebound cycle created by most diets.

Jake adjusts your plan at each step so you continue moving forward with confidence and momentum.

Most clients come to Jake after trying multiple weight loss dietitians, programs, apps and meal plans with little to no long term success.

The difference is that Jake does not use generic rules or one size fits all protocols.

He identifies the specific drivers behind your weight gain and builds a personalised clinical strategy around your body, your lifestyle, your preferences and your schedule.

Nothing is restrictive, nothing is templated and nothing relies on willpower alone.

This level of individualisation is why clients who have struggled for years finally see steady, predictable progress that lasts.

Yes. Jake offers full Telehealth consultations for weight loss through FaceTime or phone call, giving you the same clinical depth, personalised planning and ongoing support as an in person session.

Many clients prefer this format because it fits easily around work, family and training schedules while still providing clear structure, accountability and steady progress.

Yes. Jake as an accredited clinical nutritionist provides private health fund rebates for Australian residents with selected health funds and eligible premiums.

This allows many clients to claim a portion of their consultation fees depending on their individual level of cover. If you’re unsure about your eligibility, please email jake@jakebiggs.com.au and a member of Jake’s team will check your rebate options.

Absolutely, Jake is more than happy to do a complimentary discovery phone call with you to make sure he is the perfect nutritionist for you.

Please email jake@jakebiggs.com.au and a member of Jake’s team will get back to you within 24 hours to arrange a time.
