Support your nutrition while on a weight loss prescription

Are you on a weight loss prescription and experiencing little to no appetite?

Weight loss prescriptions assist with weight loss by helping to manage appetite, and they may also help to slow gastric emptying (foods and fluids emptying from the stomach).1 This can lead to feeling full earlier and for longer – resulting in a low appetite.1

As a result of a reduced appetite, meals may be skipped or low in nutrients, which can put you at risk of poor nutritional status. Therefore, it is important to ensure you are getting the nutrition you need to support healthy weight loss, which includes eating a balanced diet with lean protein sources to support muscle mass, and essential vitamins and minerals.

A balanced diet may be challenging to achieve when appetite is low, which is where a nutritionally balanced program can help. This issue can be exacerbated for people who are time poor with less time to prepare meals.

A healthcare professional recommended weight loss support program

The OPTIFAST Program is a Very Low Energy Diet (VLED) program recommended by healthcare professionals for the dietary management of overweight and obesity. It is a nutritionally complete program with very low energy food products that are used to replace 1 to 3 meals a day depending on which level of the program you are on.
