Several studies in overweight/obese adults (aged 19+ years and ethnically diverse) reported that consumption of one or more single serving portion sized meals per day as part of a weight management program resulted in improved intakes of carbohydrate, protein, fat, saturated fat, cholesterol, fiber, sodium and vitamins and minerals, depending on the nutrition guidelines followed and the single serving portion sized meals chosen. Additional studies in this area are needed.

 

• 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.

There were no studies identified to address consumption of single serving portion sized meals on nutrient intake in overweight/obese children and adolescents (aged 6-18 years).
