How to Use OPTIFAST Protein Plus Shakes on Your Weight Loss Journey
Depending on your protein requirements, you may be advised to use one or two Protein Plus products per day when you’re following an OPTIFAST diet plan. These should be consumed in place of other meal replacement products, not in addition to them.
The Protein Plus Shakes can be used during the first three-week intense phase of your diet plan as protein helps manage hunger.
These high-protein shakes can also be used when you are following a Six Week Diet Plan or Maintenance Plan, as a quick and easy option to replace your conventional breakfast.
