Making dietary changes right after being diagnosed with type 2 diabetes can make a big difference in health. Researchers assigned 593 adults newly diagnosed with diabetes to

  • usual care, consisting of two consultations with a dietitian;
  • intensive dietary intervention, advice from a dietician and monthly support meetings with a nurse; or
  • intensive dietary intervention plus moderate exercise.

At six months the intensive dietary group and the diet/exercise group enjoyed a 28 percent and 33 percent reduction in glycated hemoglobin (HbA1c), while levels worsened in the usual care group.

At one year, one-third as many who dieted or both dieted and exercised needed meds to lower HbA1c as those receiving usual care.
