Until recently, randomized clinical trials offered only limited proof that Type 2 diabetes is preventable by changes in lifestyle. Fortunately, this gap has now been filled. Several major lifestyle intervention trials have been successfully completed. The results are consistent: the risk of Type 2 diabetes can be halved in people who are at high risk; the effect of lifestyle change is rapid; the lifestyle changes required to achieve a significant risk reduction do not have to be drastic; and benefits are similar in different ethnic groups.
