What is a Very Low Calorie Diet (VLCD)?

A Very Low Calorie Diet (VLCD) - also known as a protein-sparing modified fast - is a restricted eating plan used to maximize weight loss.  The plan uses nutritional supplements (shakes, pudding, soups and bars) that replace grocery food intake.  In some cases, a VLCD may include nutritional supplements plus one meal.  A VLCD is generally limited to 800 calories a day or less.


A comprehensive VLCD has four phases:

  1. Adaptation
  2. Weight Loss
  3. Refeeding
  4. Maintenance
