To make sure you’re staying on track with your weight loss goals, it’s important to use the right number of OPTIFAST products for your diet plan. To help, we’ve created this handy guide.
Six-Week Plan
Our Six-Week Plan is designed to help you lose weight independently by following a structured framework.

When you’ve reached the final week of your Six-Week Plan, you swap out one meal replacement product for a low-calorie meal, so you’ll be consuming one OPTIFAST weight loss product and two meals low in calories per day.
If you want some inspiration for those low-calorie meals, we have a growing collection of recipes, ranging from banana pancakes to Mexican bean burgers.
Maintenance Plan
Whether you’ve reached your goal weight or a weight that you’re happy with and want to maintain, you can continue to use any of the OPTIFAST products.

On the OPTIFAST Maintenance Plan, we recommend replacing one of your daily meals with one OPTIFAST product, while the rest of your meals for the day are made using healthy, low-calorie conventional foods. In total, you should aim for a total of 1,400-1,700 calories per day.
