How does work?

Typically lasting 26 to 52 weeks, the OPTIFAST® Program is comprised of 3 phases:

  • Active Weight Loss Phase

    12 to 16 weeks of total meal replacement

    Patients start by meeting with their medical provider for monitoring and counseling. Patients will also start to consume a diet of nutritionally complete OPTIFAST® full meal replacement products.

  • Transition Phase

    2 to 4 weeks transitioning to a healthy and balanced food-based diet

    Gradually, patients transition back to self-prepared foods while they attend classes to help change their approach to food and alter their long-term lifestyle.

  • Maintenance Phase

    Up to 52 weeks with diet and lifestyle support for weight maintenance

    Patients are encouraged to participate in ongoing support sessions to help maintain their weight loss and manage their long-term weight goals. This phase may also include partial meal replacements.
