VLCD stands for
Very Low Calorie Diet

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. It can be undertaken safely with medical supervision and using specially formulated total diet replacement products to ensure nutritionally adequacy.

The OPTIFAST VLCD Program can help you achieve fast and effective weight loss with a flexible 3,2,1 step program


 

Weight loss has been shown to help improve health outcomes:

  • Improve blood glucose control1
  • Improve blood pressure control2
  • Improve quality of life1
  • Reduce blood cholesterol2
  • Reduce the pain associated with osteoarthritis3

Expected rate of weight loss

Research using Very low calorie diets (also known as VLEDs or Very Low Energy Diets) have shown on average, weekly weight losses of approximately 1.0-2.5kg per week4, 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 ketosis. This results in consistent and successful weight loss5.

Do any precautions need to be taken?

Precautions may need to be taken when using the OPTIFAST Program Intensive Level if you have any of the following:

  • Age >65 years
  • History of severe psychological disturbance, alcoholism or drug abuse
  • Cholelithiasis or past history of gall stones
  • Pancreatitis or Gout

It is essential that you seek the advice of a qualified healthcare professional who can help manage and advise you on which level of the OPTIFAST VLCD Program is right for you.

What will the program cost me?

On average, each of our products are around AU$3.75 - $5.75 RRP per meal. This may be cheaper than what you would pay for your normal weekly food requirements or for a calorie-controlled meal.

Dependent on the Level you are on, the only additional food you may need to purchase on top of your OPTIFAST VLCD products is your fresh and healthy low starch vegetables.
