Expected rate of weight loss on Intensive Level

During the Intensive Level of the OPTIFAST Program, weight loss averages 1.0 to 2.5kg/week with an average total loss of 20kg after 12 to 16 weeks1, 2, 3.
 
It is common to see a larger amount of weight loss in the first week of the Program. The weight loss in the second week will give you and your patient an idea of what to expect ongoing. Weight loss will vary between individuals and will also depend on physical activity levels. For example, both men and individuals with a higher BMI will have a greater reduction in weight because they have higher energy expenditures due to their bigger stature and relatively more lean body mass.

The table and graph below highlight the expected rates of weight loss based on BMI while following the OPTIFAST VLCD Intensive Level.

  • Overview of Very Low Energy Diets

    Very Low Energy Diets (VLED), also known as Very Low Calorie Diets (VLCD) have been shown to be very effective in the management of obesity, with weekly weight losses averaging approximately 1.0 -2.5kg per week, providing greater initial weight loss than other forms of calorie restriction.

    During the Intensive Level of the OPTIFAST Program, weight loss averages 1.0 to 2.5kg/week with an average total loss of 20kg after 12 to 16 weeks.

  • Long term weight loss goals

    It is often mentioned in the lay press and amongst healthcare professionals that "the faster you lose weight, the quicker you regain it", yet there is little evidence to support this assumption and in fact the opposite may be true.

  • Mechanics of a VLED

    A VLED works by restricting total energy intake to approximately 800 calories (3300kJ) or less per day. Weight loss with a VLED is achieved by restriction of both carbohydrate and total energy intake. This enables the body to use its body fat stores for energy via a metabolic process called ketosis.

  • Patient suitability

    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.

  • Medical monitoring

    As a healthcare professional, you can tailor the program to suit your patient's specific needs.

  • Long-term weight management with the OPTIFAST VLCD Program

    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.
