How Alex Neilan and Sustainable Change Ltd are transforming women’s health
In an industry crowded with quick-fix diets and fleeting promises, Alex Neilan has carved out a reputation for doing things differently. As the founder of Sustainable Change Ltd, he has dedicated his career to helping women achieve weight loss that lasts - not through gimmicks, but through a unique blend of science, psychology, and support, fuelled by an unwavering passion to help others.
His mission is bold yet simple: make sustainable weight loss easy for everyone, regardless of starting point. Today, the online support group community Alex leads has grown to over 90,000 members across the UK, and shows no signs of slowing down.
One group in particular has benefitted greatly from his approach: women over 50 - a demographic often left behind by the fitness industry. “Our role is to help ladies believe in themselves and, for once, put themselves first,” Alex says. “We believe it’s not about what you achieve temporarily but what you can sustain.”
Academic foundations to industry leadership
Alex’s journey into health and wellness began with a strong academic foundation, beginning with a bachelor’s degree in Sports and Exercise Science. Alex then went on to achieve a Masters in Health and Nutrition, and later a Postgraduate Diploma in Dietetics. In 2015, he qualified as a sports nutritionist and went on to gain further certifications in behaviour change, sports supplements, strength and conditioning, and dietetics.
In 2016, Alex founded Sustainable Change, committed to performance-focused nutrition coaching and weight loss advice. He had seen a pattern that he wanted to remedy. He found that people didn’t fail because they lacked will power, they failed because the systems around them were unsustainable.
The Sustainable Change approach
Sustainable Change takes a multidisciplinary and holistic approach, bringing together qualified nutritionists, psychologists, and dietitians to address both the physical and emotional aspects of health. So far, they have helped more than 4,000 women achieve life-changing results.
At the core of the company’s offering are the Free Sustainable Fat Loss trainings, expertly designed resources that remove confusion and give people a clear starting point.
Results that speak for themselves
A cursory search for “Alex Neilan reviews” will reveal hundreds of positive testimonials from clients who have used his services and seen real change. They praise the personalised coaching, empathetic support, and real-world strategies that make change feel achievable and lasting.
Unlike the high-pressure, unrealistic targets common in the fitness industry, Alex’s methods help clients build habits they can maintain for life - leading not only to weight loss but also improved confidence, energy, and overall wellbeing.
This success has earned Alex international recognition. In an interview with Forbes, in which he shared his “Secrets to a healthier life” Neilan advised readers to stop procrastinating, prioritise on your own progress, and focus on sustainable lifestyle shifts rather than extreme overhauls.
A commitment to giving back
Alex’s mission extends beyond his client base. Through Sustainable Change, he and his team have raised over £130,000 for causes including UNICEF’s Children of Gaza Crisis Appeal, the Stroke Association, Magic Breakfast, Make-A-Wish UK, and bowel cancer research. Whether assembling record-breaking Tough Mudder teams or completing endurance challenges like climbing Edinburgh’s Arthur’s Seat, the equivalent of Mount Everest, Alex applies the same energy and determination to charity as he does to coaching.
A vision for the future
Beyond his current success, Alex has ambitious goals: to reach one million women worldwide with practical, compassionate health guidance. As Sustainable Change grows, he plans to expand its resources, strengthen its online community, and continue challenging the industry’s obsession with quick fixes.
For women seeking a healthier life without the burnout of fad diets, Alex Neilan’s message is clear: with the right guidance, lasting change isn’t just possible, it’s sustainable.
