What is the maximum caloric intake for a very low calorie diet (VLCD)?

A very low calorie diet (VLCD) is typically defined as providing fewer than 800 calories per day. This level of caloric intake is designed for individuals who are severely obese and requires close medical supervision due to the significant calorie deficit. The purpose of a VLCD is to facilitate rapid weight loss while ensuring that the individual receives essential nutrients through meal replacements or very specific food selections.

In clinical settings, VLCDs often consist of specially formulated products designed to meet nutritional needs within the restrictive caloric intake. Maintaining a caloric intake at or above 800 calories may not qualify as a VLCD, as the distinction lies specifically in the intake being below this threshold.

This understanding of VLCD is essential for safe and effective weight management protocols and reflects the guidelines established for significantly obese individuals when rapid weight loss is medically necessary.
