You’re tired, exhausted and burnt out, but it doesn’t have to stay that way. Jake provides adrenal‑fatigue nutrition therapy that goes straight to the root cause rather than managing symptoms, so your body can finally recharge, re‑energise and return to a state where you feel clear, stable and able to function at your best.

Wellbeing covers two distinct, deeply interconnected areas. Both respond powerfully to clinical nutrition when generic advice falls short.
Adrenal Fatigue
Chronic stress, low energy, wired-but-tired, poor recovery, salt cravings, brain fog. When your body has been in survival mode for too long, the systems that regulate energy, stress, and resilience stop working the way they should. Jake builds nutrition strategies that calm the stress response, restore depleted reserves, and rebuild your baseline.
Sexual Health
Low libido, sexual dysfunction, hormonal disruption affecting desire and function, intimacy concerns. Nutrition affects every system that supports sexual health, blood flow, neurotransmitters, hormones, and energy availability. Evidence-based support for men and women of every age.
Heart Health
Your heart is the centre of your long‑term health, stability and longevity. Jake provides clinical heart‑health nutrition therapy that targets the underlying drivers of cardiovascular strain, cholesterol imbalance, blood pressure instability, inflammation, nutrient deficiencies and metabolic stress.
Chronic stress is one of the most underestimated drivers of poor health in Australia. It disrupts your energy, your sleep, your mood, your digestion, your immunity and your ability to function with stability.
Most people are told to manage stress or accept burnout as a normal part of modern life, but both responses leave the underlying adrenal biology untreated. Jake’s approach goes further, using clinical nutrition to correct the root drivers of adrenal fatigue rather than the surface symptoms, helping your body return to clarity, resilience and long‑term physiological balance.
65%
of people with burnout show measurable nutrient depletion
Key nutrients involved in adrenal recovery include magnesium, B‑vitamins, zinc and omega‑3s. They are often significantly reduced during prolonged stress.
1in3
adults experience stress‑related hormonal disruption
Cortisol instability contributes to blood‑sugar swings, inflammation, cravings, anxiety patterns and difficulty regulating daily rhythms.
72%
of Australians report persistent stress symptoms
Chronic stress is now one of the most common drivers of adrenal dysregulation, affecting energy, sleep, mood and metabolic stability.
Energy collapse
Your body can no longer hold stable energy because your adrenal system is depleted and misfiring.
Bone‑deep fatigue
Rest stops working as your recovery hormones lose their rhythm and fail to replenish your system.
Mood volatility
Irritability and emotional swings intensify as cortisol and neurotransmitter pathways become unstable.
Wired insomnia
Your brain stays alert at night and heavy in the morning because your stress hormones are mistimed.
Motivation crash
Your drive disappears as your system runs without the physiological reserves needed for daily function.
Cognitive fog
Thinking slows and clarity fades as stress chemistry disrupts blood sugar, inflammation and brain signalling.

Restoring wellbeing requires a whole-system view. Jake’s clinical process goes far beyond standard nutrition consultation, it’s a thorough investigation into what’s draining you and a targeted plan to correct it.
01
Deep, full-body assessment
Jake reviews your symptoms, health history, current medications, lifestyle patterns, sleep quality, stress load and intimacy concerns to understand exactly how your adrenal system is functioning. He builds a complete clinical picture before making any recommendations, ensuring every step targets the true drivers of your adrenal fatigue rather than the surface symptoms.
02
Root cause identification
Rather than treating symptoms in isolation, Jake identifies the nutritional and lifestyle drivers of your wellbeing concerns, HPA axis dysregulation, micronutrient depletion, blood sugar instability, gut dysfunction, or dietary patterns.
03
Personalised nutrition protocol
A tailored plan built around your specific presentation, covering macronutrient balance, targeted micronutrients, meal timing, and evidence-based strategy where appropriate.
04
Your goals are the engine of your results
Strategic short and long term goal development for adrenal fatigue gives you a clear roadmap for what to focus on now, what to build toward over time and how to create lasting change in the way your adrenal system functions. It brings structure, clarity and direction to your entire recovery process so you always know the next step, the purpose behind it and how it supports long‑term hormonal stability and resilience.
05
Ongoing monitoring & support
Wellbeing recovery takes time. Jake provides message support between sessions and adjusts your plan as your body responds, so you’re never navigating the process alone.

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.
