When most people think about improving their health, they focus on food or exercise. They sign up to a new gym. They download a calorie-tracking app. But according to Alex Neilan, founder of Sustainable Change Ltd, these tools won’t work unless you fix the foundation first: your mindset.
“Your thoughts drive your actions,” Alex explains. “If you don’t believe change is possible, no diet or training plan will stick.”
It’s a lesson he has seen confirmed again and again in his work. With degrees in sports science, nutrition, and dietetics, plus specialist training in behaviour change, Alex combines scientific knowledge with an understanding of how people think.
Many people who join Sustainable Change arrive with a long history of failed diets. Karen, 54, remembers reaching the point of giving up: “I didn’t think I could do it anymore. But once I changed how I thought about myself, everything else became easier.”
Within months, she had more energy, less joint pain, and – most importantly – renewed confidence. Her story is echoed across a community of more than 93,000 members, many of whom say the biggest transformation wasn’t physical but mental.
Alex Neilan emphasises that setbacks are not failures. Missing a workout or eating off-plan doesn’t mean the end. “Setbacks are feedback,” he tells his members. “Learn from them and keep moving forward.”
That mindset shift is powerful. Instead of seeing health as a series of all-or-nothing attempts, members learn to treat it as an ongoing journey. It’s one reason why Sustainable Change holds a 4.8-star Trustpilot rating and continues to grow through word of mouth.
Tools for Everyday Mindset Shifts
Mindset training isn’t reserved for paying clients. Alex’s YouTube channel, Alex Neilan – Sustainable Change, is filled with free resources designed to help people change the way they think about health. Videos such as The 3 Secrets of Sustainable Weight Lossexplain not only what to do, but how to approach the process without fear of failure.
In an industry that often reduces health to numbers on a scale, Alex Neilan is encouraging a more compassionate path. His message is simple: perfection isn’t required. What matters is progress, persistence, and patience.
“Self-doubt doesn’t mean you’re failing,” he says. “It means you’re trying to grow. Once you start to see it that way, lasting change becomes inevitable.”
Mindset isn’t a side note – it’s the foundation. And for Alex Neilan, helping people rebuild that foundation is what makes sustainable health possible.
In a culture full of quick fixes, his message cuts through the noise: change how you think, and you’ll change your life.
