  • 144 obese patients with high blood pressure.


  • Participants were randomised to the DASH diet alone, the DASH diet combined with a behavioural weight management program, or to the usual diet control group.


  • Blood pressure was reduced by 16.1/9.9 mm Hg (DASH plus weight management); 11.2/7.5 mm (DASH alone); and 3.4/3.8 mm (usual diet controls).
  • For overweight or obese persons with above normal blood pressure, the addition of exercise and weight loss to the DASH diet resulted in even larger blood pressure reductions, greater improvements in vascular and autonomic function, and reduced left ventricular mass.


  • The DASH diet, particularly when supported by exercise and weight loss, can offer considerable benefit to patients with high blood pressure.


Editors Notes

  • Participants in the DASH diet consumed meals at a 500-calories-per-day deficit to allow weight loss of about 1 pound a week.
  • DASH included a diet high in low-fat dairy products, fruits, and vegetables; lower in fats; and rich in fibre.
