Why Second Nature?

The Challenge

Obesity has become a global epidemic; in the UK, we spend £9 billion a year alone on diseases like type 2 diabetes (that’s 10% of the NHS budget). What’s shocking is most of this is preventable – through sustained lifestyle and habit change.

Enter Second Nature.

We’re here to help people take control of their health. By bringing together behavioural science, technology, and incredible people, our grand mission is to eradicate the global epidemic of chronic lifestyle diseases once and for all.

Our digital habit change programme – delivered digitally through mobile and web apps – helps people to improve their lifestyle, lose weight, and ultimately reduce their risk for conditions such as type 2 diabetes.
