Single Serving Portion Sized Meals and Weight Management

SSPSM: Weight Maintenance (2014)

• Intervention
  In overweight/obese adults (aged 19+ years), what is the effect of consuming single serving portion sized meals on weight maintenance?

  • Conclusion
    Four studies show that weight loss was maintained with continued consumption of one or more single serving portion sized meals per day as part of a weight management program for six to 12 months in overweight/obese adults (aged 19+ years and ethnically diverse). Without a planned weight maintenance phase during the weight management program, weight loss may or may not be maintained over 12-18 months. Additional studies in this area are needed.

    • 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.
