Hey, I’m Jake! I help clients who have tried everything to lose weight but keep rebounding. Together, we achieve their goal weight — and maintain it for life — without Ozempic, calorie counting, restrictive dieting, hunger and without sacrificing their social life. It’s not dieting — it’s effortless, sustainable weight loss.
As a sports nutritionist, I work with teenagers, adults, gym enthusiasts and aspiring athletes to unlock peak performance and achieve their best-ever physiques through tailored sports nutrition plans. As a clinical nutritionist, I find out exactly what my clients health goals are and deliver personalised nutrition plans to achieve their dream health.
Many clients come to me feeling stuck, frustrated, and ready to give up — they’ve tried everything, but nothing works. They need a clear, practical plan — and that’s exactly what I provide. My approach is empathetic, supportive, and completely customised to you.
EXCELLENT Based on 135 reviews 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! 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.Posted on Divya GirishTrustindex verifies that the original source of the review is Google. 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.

His expertise in nutrition is exceptional, and what sets him apart is not just his deep knowledge, but the genuine care he shows for his clients, both during sessions and beyond. Jake has supported me every step of the way with practical, sustainable advice tailored specifically to my goals. His unlimited WhatsApp support between sessions has made a huge difference, allowing me to stay on track and feel supported at all times, not just during appointments. 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. If you’re looking for a weight loss nutritionist that delivers incredible results, then I’d highly recommend Jake. He gave me a tailored plan and supported me the whole way. I was able to lose 5 kgs in 7-weeks. He also gave me all the tools and knowledge to now live a healthier and more sustainable life when it comes to diet, exercise, sleep and stress. His deep knowledge is more than you’ll ever be able to get from ChatGPT, combined without of hours support has meant that my consults have been able to fit into my busy life.Posted on Seth PangTrustindex verifies that the original source of the review is Google. Jake Biggs is, without a doubt, the best sports nutritionist I’ve ever worked with.

His expertise in sports nutrition has completely transformed my energy, enhanced my performance, and given me a crystal-clear understanding of what my body needs to perform at its absolute best.

The personalised strategies he developed for me were nothing short of a game changer. I’ve never felt stronger, more focused, or more confident in my nutrition.
