The OPTIFAST® program is a medically-supervised weight loss program that closely monitors and assesses progress towards better health and emotional wellbeing.
The program utilizes a meal replacement plan that transitions to self-prepared ‘everyday’ meals, in conjunction with comprehensive patient education and support.
Results show that OPTIFAST's science-based weight-loss solution helps people lose weight fast, effectively and safely. That's thanks to a medically-supervised program that educates and offers people support, resulting in better health and emotional wellbeing.

When you start our program phases, your body begins to burn fat cells for energy, and there’s no need to eat carbs for energy. Ketosis — when the body starts using excess fat stored, instead of carbs — decreases appetite, making it easier to follow the program.
