About us
Most diseases of modern life can be prevented. Many can be reversed.
We build the evidence, teach it widely and campaign for policies that put prevention first.
Our vision
A country where the diseases of modern life are prevented, not just treated.
Our mission
To empower, inspire and educate people that most chronic diseases can be prevented and reversed by maintaining good metabolic health through sustainable lifestyle changes.
What we stand for
Four principles
Common risks, many outcomes
Many of the diseases people fear most share common risks we can change, from smoking and alcohol to what we eat, how we move and sleep, chronic stress and our wider circumstances. Improve them and the risk of several diseases falls at once.
Evidence first
We only claim what the evidence supports, say openly how strong it is and link every figure to its source.
For prevention, not against treatment
We make the case for prevention and work alongside doctors and the NHS. We never ask anyone to stop treatment they need.
Independent
We follow the evidence, not a diet tribe or a sponsor. We promote no products, and we work with every party, never against one.
