The OPTIFAST six week diet plan is designed to help you lose significant amounts of weight. You replace all meals and snacks with four OPTIFAST products a day, for the first three weeks. These products are nutritionally complete and will ensure you receive all the necessary vitamins and minerals – containing a total of approximately 800 calories.  

For the following three weeks, you can re-introduce convention foods into your diet, beginning with non-starchy vegetables and lean protein. This plan focuses on the consumption of nutritious whole foods and minimal carbohydrates, as opposed to typical processed food products.

As the plan progresses, you will transition from 800, to 1400, to eventually 1700 calories per day. Once the six week plan is complete, you will transition on to the long-term Maintenance Plan, where you adopt a Mediterranean-inspired diet.
