Recommended for You: Partial Meal Replacement

Our Partial Meal Replacement Plan is our most flexible option. You create your own plan by deciding how many conventional meals you want to replace each day — up to three — with OPTIFAST meal replacements. You can eat more conventional foods than under the other plans. But the more meal replacements you choose, the more weight you lose.

How It Works:

The first 6 months are active weight loss – you can choose up to 3 OPTIFAST meals a day combined with one self-prepared meal using minimally processed conventional foods (1200-1500 cal)

After six months, you replace one conventional meal a day with an OPTIFAST meal replacement and your daily goal increases to 1,400 to 1,700 calories.
