Alex Neilan on what’s really behind sustainable health change

When it comes to health and wellbeing, Alex Neilan has become one of the UK’s most distinctive voices - not because he promises rapid transformation, but because he refuses to. His company, Sustainable Change, has built its reputation on science, structure and empathy, guiding thousands of women to achieve health improvements that last. Alongside it, his Sustainable Weight Loss Support Group on Facebook - now approaching 100,000 members - has grown into one of the UK’s largest online wellbeing communities.

“People think health change starts with willpower,” he says. “But real, sustainable change starts with understanding - how we eat, how we move, and how our lives actually work. The system has to fit the person, not the other way around.”

Alex Neilan and the rise of Sustainable Change

It’s a simple idea that has fuelled Neilan’s rise as one of the most respected figures in evidence-based health coaching. His approach is practical, deeply human and deliberately unglamorous - the antithesis of an industry built on hype and hashtags.

“Most people don’t fail because they’re lazy,” he explains. “They fail because the plan wasn’t built for their life. You can’t ask a busy mother or business leader to train like a professional athlete. You have to create systems that work on the days when motivation disappears - because it will.”

That realism has made Alex Neilan stand out in a crowded wellness market. He’s not selling perfection; he’s selling permission - the freedom to improve without starting from scratch every Monday. His method focuses on what he calls “health design”: setting up habits, routines and environments that make positive choices automatic rather than forced.

What began as a one-to-one coaching practice in 2016 has evolved into a company with a national footprint. Sustainable Change now supports women across the UK through structured programmes built around behavioural psychology, nutrition science and emotional resilience. The emphasis is on habit-building, not restriction. As Neilan puts it, “You don’t need to overhaul your life. You just need to stop stopping.”

He laughs when asked how he feels about being described as a “disruptor” in the health world. “It’s funny - I’m not trying to disrupt anything. I’m trying to fix what’s broken. People don’t need louder messages; they need clearer ones.”

Building a community, not a client base

Much of his success, he admits, has come from listening rather than leading. Through years of working directly with women - often those who have felt ignored or alienated by traditional fitness culture - Neilan has built not just a client base, but a community. The Sustainable Weight Loss Support Group is now a thriving digital ecosystem where members share progress, trade advice and ask questions without fear of judgement. It’s a space that replaces competition with connection.

“The reason people stay,” he says, “is because it’s not performative. You don’t have to prove anything to belong. It’s about learning, applying, and supporting each other through real life.”

That sense of belonging, he believes, is the missing ingredient in most wellness models. “You can give someone the perfect nutrition plan,” Neilan says, “but if they feel alone, it won’t last. Health is social. It’s relational. When people feel seen and supported, everything changes.”

His academic background - spanning Sports and Exercise Science, Health and Nutrition, and Dietetics - gives him the credentials to speak with authority, but it’s his clarity that makes his voice resonate. Whether in interviews, workshops, or his widely viewed live Facebook sessions, Neilan’s advice always loops back to the same message: progress is built on structure, not emotion.

He recalls one of his earliest clients, a woman who described herself as “hopeless” after years of failed diets. “All we did was build structure around her life,” he says. “Two weeks later, she realised she didn’t need more motivation - she just needed less friction.”

Moments like that, he says, are what keep him going. “You see someone stop doubting themselves and start believing again - that’s the real transformation.”

Redefining leadership in health

As Sustainable Change continues to grow, Neilan is focused on maintaining the integrity of its message. Expansion, he says, should never come at the cost of quality. “The moment you chase scale for its own sake, you lose the connection that made it work in the first place. We’re building something that lasts - for real people, in real lives.”

It’s a philosophy that feels increasingly relevant in a culture saturated with noise. In the end, Neilan says, sustainability is not just a health principle - it’s a leadership one.

“You don’t need to be extreme to be effective,” he says, smiling. “You just need to be consistent - and willing to start small, every day.”
