A recent study published in Diabetes Education compared the efficacy of a portion-controlled meal replacement diet (PCD) to a standard diet (SD) based on American Diabetes Association recommendations in achieving and maintaining weight loss.
Participants included 119 overweight men and women with type 2 diabetes and a body mass index (BMI) between 25 and 40. Subjects were randomly assigned to one of two diets (PCD or SD) that contained 75% of predicted energy needs. The diets were then followed by a maintenance phase of one year.
Weight loss at 34 weeks and weight maintenance at 86 weeks was significantly better on PCD versus SD. Approximately 40% of the PCD participants lost at least 5% of their initial weight compared with only 12% of those on the standard diet. Significant improvements in biochemical and metabolic measures were observed at 34 weeks in both groups. The ease and self-reported adherence to the diet were greater in the PCD group throughout the study.
In this study, a diet using portion-controlled meal replacements resulted in significantly greater initial weight loss and less regain after one year of maintenance than a standard, self-selected, food-based diet. As PCDs may help obese patients with type 2 diabetes adhere to a weight control program, diabetes educators should consider recommending them as part of a comprehensive approach to weight control.
