We’re on a mission to empower millions of people to make lifestyle changes that last a lifetime.

We are Changing Health

The challenge

1.9 billion

adults are now overweight or obese. (That’s 25% of the global population).

$2 trillion

economic burden as a result of the overweight global population.

If current trends continue, 3.2 billion people, or 38% of the population will be overweight or obese by 2030, creating a crippling economic impact.

Our journey

It started in the lab

With over 100 peer reviewed published papers and collaborations with Newcastle University, Southampton University, the UK National Institute for Health Research (NIHR), the Medical Research Council (MRC) and Diabetes UK, our founding team are at the forefront of lifestyle change innovation.

Co-founder Professor Mike Trenell co-authored the randomised clinical trial Movement as Medicine for Type 2 Diabetes that created the framework in which Changing Health programmes are built. With IP and licenses from these leading studies, Changing Health is able to provide an unparalleled evidence base that is helping to set the standard in digital therapeutics.

The science turned digital

Changing Health is able to provide en masse highly personal and relevant evidence based education and lifestyle coaching, leading to cost effective scale, with a sustained positive impact. Driven by our own artificial intelligence (AI) engine, users can receive education and support based on their needs and preferences.

Then we got personal

As great as AI is, everyone is unique, with their own story, background, goals and dreams. Psychologists know that in order for a behaviour change intervention to create lasting impact, the techniques must be based on a myriad of factors that are developed around a trusted relationship.

As such, each of our programmes are unique to the psychology of the condition and person, each user receives a personal experience from their coach based on their own goals and background.

Now it's about real world data

From tracking a user's movement, to randomised clinical trials and auditing our NHS sites, Changing Health is focused on showing the real world impact of it’s programmes.

However, beyond the studies, we’re improving people’s lives and showing that conditions like Type 2 diabetes can be put into remission in as little as 10 weeks.
