Several short-term studies reported that consumption of one or more single serving portion sized meals per day as part of a weight management program resulted in weight losses ranging from approximately 3.4 to 10.3 kg for eight weeks to six months in overweight/obese adults (aged 19+ years and ethnically diverse), depending on the level of caloric restriction. In addition, long-term studies reported weight losses up to approximately 10.1 kg with consumption of one or more single serving portion sized meals per day as part of a weight management program for 12-18 months.



 

• 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 weight loss in overweight/obese children and adolescents (aged 6-18 years).
