How does it work?

The Active 1 Level of the OPTIFAST VLCD Program continues to work by restricting calories, which on Active 1 Level are approximately 1,200 calories per day.

During the Active 1 Level you will be replacing 1 meal with an OPTIFAST VLCD product.

You will also need to have:

  • 2 low-calorie meals (approximately 350 calories each)
  • 2 or more cups of low starch vegetables
  • 2 litres of water or calorie-free fluids (minimum)
  • 2 serves of fruit (approximately 70 calories)
  • 1 serve of dairy (approximately 100 calories)

This Level brings your total food intake, including your OPTIFAST VLCD product, to approximately 1200 calories per day. The length of time that you are on this level will depend on your lifestyle needs and weight loss goals.

What is a ‘low starch vegetable’?

Below is a list of low starch vegetables, as well as vegetables to avoid due to their higher carbohydrate and calorie content. The OPTIFAST VLCD Program recommends at least 2 cups a day of allowed vegetables, however increasing that quantity makes little difference to your weight loss and may help to keep you satisfied. Vegetables can be raw or cooked - it doesn’t matter which.

FAQs

Yes, some people may choose to start on the Active 1 Level of the OPTIFAST VLCD Program or are advised to do so by a healthcare professional. The Active 1 Level is still suitable for people who require significant weight loss. This level restricts calorie intake but not as much as the Intensive level.

No, the Active 1 Level works through calorie restriction, not ketosis. The Intensive Level is the only OPTIFAST Program Level that utilises ketosis.

Your calorie-controlled or low-calorie meal should be around 350 calories. Aim for 1 serve or ¼ of your plate to be protein (100g meat or chicken, 130g white flesh fish, 2 eggs or 150g tofu), 1 serve or ¼ or your plate to be grains (2 slices of bread, 1 cup cooked pasta, ¾ cup of rice or 1 medium potato) and fill half the plate with low starch vegetables or salad. You can also include 1 tbsp of a sauce or dressing. This plate concept will help to keep your meal under 350 calories. Alternatively, check out the calorie- controlled recipes in the recipe section of the website or on the OPTIFAST My Program app. Each recipe indicates how many calories per serve.

If you are concerned about transitioning through the other levels of the OPTIFAST VLCD Program, consult an Accredited Practising Dietitian who will be able to help you with this transition as well as educate you regarding appropriate foods to include, portion sizes and how to manage your daily calorie intake, as this can be individual. For tools to help guide you as well as recipe ideas, download the OPTIFAST My Program app.

The OPTIFAST VLCD Program is designed so that you can interchange or have any combination of the OPTIFAST VLCD products that suit your preference and lifestyle. This includes OPTIFAST VLCD Shakes, Soups, Bars and Desserts. If you choose to have more than 1 bar a day, ensure that you consume extra water as you will not be getting the fluids that you would with the sachet products.

It really doesn't matter which meals you decide to replace with an OPTIFAST VLCD product. The program is designed so that you can choose which meals you would prefer to replace based on your likes and lifestyle. The evening meal is generally replaced with a healthy meal in the Active 2 Level, purely for social reasons, however you can tailor the program to suit yourself and substitute the morning meal or lunch instead.
