More than 5,000 people are to test apps, gadgets and wristbands similar to Fitbits which will track sleep and their activities as part of a 12-month trial.
Public Health England said the pilot scheme – which will run in eight areas of the country – is “the next logical step in diabetes prevention”.
The technology being used includes a Buddi Nujjer device – which monitors activity, sleep and eating and has an app which can help with diet – while people will also be given educational software and personal coaching sessions.
Professor Jonathan Valabhji, national clinical director for obesity and diabetes, said: “Tackling obesity and the rising prevalence of Type 2 diabetes are the major public health challenges of our time.
“Through this initiative, we have the potential to establish the effectiveness of digital interventions to do the same, so that the reach of the programme will be even greater.“
Simon Stevens, the CEO of NHS England, said: “So much else in our lives is now about online social connection and support, and that now needs to be true too for the modern NHS.
“This new programme is the latest example of how the NHS is now getting practical and getting serious about new ways of supporting people stay healthy.”
Some 2.9 million people in England are already diagnosed with Type 2 diabetes, with obesity seen as a key driver.
Figures suggest that Type 2 diabetes leads to 22,000 early deaths every year and costs the NHS around £8.8 billion.
