The Optifast VLCD Program

WRITTEN & SUPPLIED BY OPTIFAST.

The OPTIFAST Program is a clinically proven, scientifically designed very low calorie diet (VLCD) program recommended for the dietary management of obesity.

A VLCD is a diet that provides 800 calories or less per day, whilst consisting of sufficient protein, fatty acids, carbohydrates, vitamins and minerals for safe and rapid weight loss.

Research using VLCDs has shown on average, weekly weight losses of approximately 1.0-2.5kg per week1, providing greater initial weight loss than other forms of calorie restriction.

Reducing energy (calorie) intake to less than 800 calories as well as reducing carbohydrate intake leads to a whole body shift towards fat stores being utilised as the major source of energy through a process called ketosis1,2. This helps to achieve consistent and successful weight loss.
