Losing just a few kilograms in weight almost halves the risk of developing type 2 diabetes, according to the large-scale Norfolk Diabetes Prevention Study.
NDPS has been running for 8 years, and involved more than 1,000 people at high risk of developing type 2 diabetes.
It found that making lifestyle changes including losing 2-3 kgs of weight, and increasing physical activity for over two years reduced the risk of type 2 diabetes by between 40 and 47% for patients with prediabetes. Importantly, the changes were sustained for at least two years and weight lost was not regained.
Earlier studies have used a more intensive and expensive intervention to reduce the development of type 2 diabetes or to reverse the diagnosis.
Prof Jonathan Valabhji, National Clinical Director for Diabetes and Obesity for NHS England, said: ‘This study with similar referral criteria and a similar intensive lifestyle intervention to the NHS Diabetes Prevention Programme has surpassed expectations in preventing type 2 diabetes. This is hugely encouraging for the NHS Diabetes Prevention Programme, and what participants might expect to achieve in the longer term.’
