What is a VLCD?

Very Low Calorie Diets (also known as VLEDs or Very Low Energy Diets) have been shown to be very effective in the dietary management of obesity.

Expected rate of weight loss?

During the Intensive Level of the OPTIFAST VLCD Program, on average: men lose 1.5-2.5kg per week, and women lose 1-2kg per week.

Ketosis and the 3 day challenge

Ketosis is a metabolic reaction that occurs in the body when following the OPTIFAST VLCD Intensive Level.

Patient suitability

The OPTIFAST VLCD Program may not be suitable for some patients. Medical supervision is advised.

Determining readiness

For a patient to succeed with the OPTIFAST VLCD Program, it is important to assess their readiness to undertake the necessary behaviour changes required for effective weight management.

Calculating ideal body weight

Ideal body weight is calculated to help determine an appropriate weight for height or to determine a long term weight loss goal. We recommend that you use the ‘Adjusted Ideal Body Weight’ calculation.

Calculating protein requirements

OPTIFAST VLCD is formulated to contain adequate high quality protein in sufficient quantities for nitrogen sparing and to preserve lean body mass.

Role of the healthcare professional

Research has shown that having the support and guidance of a healthcare professional will make the program more successful for your patients.

Bariatric surgery and the OPTIFAST VLCD Program

Surgical intervention by way of bariatric surgery can result in substantial weight loss that is sustained over the long term when combined with education, ongoing monitoring and patient support.

Diabetes and the OPTIFAST VLCD Program

Most overweight and obese patients with Type 1 or Type 2 diabetes are eligible to use OPTIFAST VLCD as part of an overall management program that emphasises the importance of ongoing weight maintenance.
