About Optifast​

Optifast is a medically supervised weight loss and management program centered around the product Optifast Meal Replacement Shakes. With many weight loss programs out there, Optifast is one of the few clinically proven (meaning they have done studies to show that it is safe and effective). The Optifast Meal Replacement Shake itself comes in two different flavours (vanilla and chocolate) and is mixed with water. 

The Optifast Shake is a full meal replacement, providing everything your body needs: protein, carbohydrates, healthy fats, vitamins and trace minerals. When consuming 4 shakes daily, your intake will be 900 calories and 90g protein. This creates a low-calorie intake while providing your body with all the nutrients it needs and effectively facilitating weight loss.
