The Evolution of Very‐Low‐Calorie Diets: An Update and Meta‐analysis

Abstract
Objective: Very‐low‐calorie diets (VLCDs), providing 0.2). Attrition was similar with VLCD and LCD regimens.Discussion: VLCDs did not produce greater long‐term weight losses than LCDs. In the United States, the use of liquid meal replacements as part of a 1000 to 1500 kcal/d diet may provide an effective and less expensive alternative to VLCDs. In Europe, VLCDs are used with less intensive medical supervision than in the United States, which reduces the cost of this approach.
