Dietary Approaches and Health Outcomes

DAHO: Overweight and Obesity (2021)

• Intervention
  In adults with overweight or obesity, what is the effect of Mediterranean diet intake compared to usual or other therapeutic diet intake on weight, blood lipids and cholesterol?

  • Conclusion

    In adults with overweight and obesity, Mediterranean diet intake may reduce weight, LDL cholesterol, and systolic blood pressure compared to usual diet intake. Mediterranean diet intake may not affect HDL cholesterol, diastolic blood pressure, or CRP compared to usual diet intake.

  • Grade: Moderate (B)
    • 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.
