How does OPTIFAST work?

Optifast VLCD uses an established medical technique - a very low calorie diet (VLCD) - for rapid weight reduction. Reducing your calorie intake to below 800 Kcal (3344kj) per day means your body draws its energy from your own fats stores. Quite literally, you live off your own fat.

Optifast VLCD contains carbohydrates, essential fatty acids and high quality protein which helps to preserve lean body mass (muscle) while you lose your fat stores. It has been designed to be the sole source of nourishment and therefore contains the recommended dietary intake (RDI) of vitamins, minerals and trace elements.

Optifast VLCD is designed to totally replace your normal food intake

Very Low Energy Diet: Replace all meals with three sachets (54g) per day. Additionally, 2L or calorie free fluids and 2 cups of low starch, green vegetables should be consumed.
Optifast VLCD Dessert can also be used in combination with Optifast VLCD Milkshake.

Add the contents of one sachet (54g) to 200mL of cold water and mix vigorously with a whisk or fork. Leave to stand 5 minutes preferably in a refrigerator. Store covered in refrigerator (<4C). Use within 24 hours.

Very low calorie diets (VLCDs) should only be used where rapid weight loss is essential to health and wellbeing as recommended and supervised by medical professionals experienced in the use of modified fasting. Take an additional 2 litres of calorie-free fluid each day. Unsuitable for use by pregnant or nursing women, infants and children, adolescents and elderly.
