Outpatient Services > Optifast Program

The Duke Diet & Fitness Center is proud to offer OPTIFAST®, one of the most successful and in-demand weight loss strategies available today. Under the supervision of Dr. William Yancy this program helps patients take control of their weight with a comprehensive, physician-supervised weight loss plan.


What is OPTIFAST? 


OPTIFAST is a multi-disciplinary approach to weight loss that tackles excess weight from every angle.  We currently offer a 9-week and an 18-week program.  Both programs involve:

  • A meal replacement-based strategy to kick start weight loss 
  • Weekly support group meetings led by psychologists, dietitians and exercise physiologists
  • Medical supervision to help you attain your goals and manage weight-related medical problems such as diabetes or high blood pressure 

OPTIFAST is only available at certified weight loss clinics. The Duke Diet & Fitness Center has been a certified Optifast clinic since 2012.

How does OPTIFAST work?


Patients start with a meal replacement-based program and learn how to transition to eating healthy, low-calorie meals to help them sustain their weight loss. They receive guidance from our expert dietitians, who work with patients to develop nutrition plans tailored to their needs and preferences. 

OPTIFAST has two phases: 

  • Active Weight Loss: 6 to 14  weeks (depending on program length) of full meal replacement strategy with OPTIFAST products 
  • Transition Phase: Patients begin eating self-prepared or bought regular food again while continuing their weight loss

OPTIFAST patients have weekly clinic visits and group meetings to help them achieve their new lifestyle and weight loss goals. In the group meetings, our behavioral specialists, dietitians and exercise physiologists help guide patients through the challenges of losing weight successfully plus help patients develop long-term strategies for sustained weight loss.   Our exercise specialists offer training sessions at discounted price with the goal of creating a customized exercise plan.

At program completion, clients are encouraged to take advantage of our outpatient medical, nutrition and behavioral services that can be billed to insurance.


Is OPTIFAST right for me? 


OPTIFAST is not a temporary diet. The program is a comprehensive approach to weight loss that helps patients lead healthier lives by overhauling their approach to eating and physical activity. This is a direct result of our tailored behavior counseling and medical supervision. 


OPTIFAST is typically designed for patients with a BMI, or Body Mass Index, greater than 30 or those who need to lose at least 50 pounds. Use our BMI Calculator.
