  • Intervention
    In overweight and obese adults, what is the effectiveness of MNT provided by a Registered Dietitian Nutritionist (RDN) on weight management outcomes?
    • Conclusion

      In overweight or obese adults, strong evidence supports the effectiveness of multiple visits (two to 12 visits, 60-minute initial visit and 20- to 45-minute follow-ups) for Medical Nutrition Therapy (MNT) by a nutrition professional (registered dietitian nutritionist or equivalent). Compelling evidence supports improved weight (-0.5kg to -9.0kg), BMI (-0.2kg/m2 to -7.8kg/m2), waist circumference (-2.0cm to -14cm), FBG (-5.2mg to -9.5mg per dL), total cholesterol (-4.3mg to -59mg per dL), LDL-cholesterol (-15mg to -47mg per dL), HDL-cholesterol (+2.0mg to +11mg per dL) and triglycerides (-12mg to -60mg per dL).

    • Grade: I
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.
    In overweight and obese adults, what is the cost benefit of MNT provided by a Registered Dietitian Nutritionist (RDN)?
    • Conclusion

      Consistent evidence supports the cost-effectiveness, cost benefit and economic savings of Medical Nutrition Therapy (MNT) provided by a registered dietitian nutritionist (a qualified nutrition professional) in overweight and obese adults. Using a variety of cost-effectiveness analyses, the studies affirm that MNT resulted in improved weight loss and improved quality of life. Continued research is needed on the cost-effectiveness, cost benefit and economic savings of outpatient MNT for weight management.
