The Active 1 Level of the OPTIFAST VLCD Program continues to work by restricting calories, which on Active 1 Level are approximately 1200 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 (around 70 calories each)                                                                                                                      

-1 serve of dairy (around 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. 

The Active 1 Level can be used as a meal replacement program for individuals with a BMI of 25-30 kg/m2 who want to lose weight but for whom the Intensive Level is not recommended.

Some people may choose to stay on the Active 1 Level long term as part of a long term weight management strategy.
