Intervention
In adults, how effective (in terms of client adherence and weight loss and maintenance) are meal replacements (liquid meals, meal bars, frozen prepackaged meals)?
-
Conclusion
Several studies comparing isocaloric diets have shown an equivalent or greater weight loss efficacy with structured meal replacement plans, compared to reduced calorie diet treatments. One or two daily vitamin- and mineral-fortified meal replacements, supplemented with self-selected meals and snacks, may be a successful weight loss and weight maintenance strategy for overweight and obese adults who have difficulty with self-selection of food and portion control.
