The Scientific Method: OPTIFAST

Centegra Health System’s new OPTIFAST program offers residents in McHenry County a new approach to medically supervised weight loss. The program usually lasts 26 weeks and uses a full meal replacement plan that transitions to self-prepared “everyday” meals along with comprehensive patient education and support. OPTIFAST helps patients achieve long-term weight loss.

Designed for people who are severely obese, the OPTIFAST program is successful because it treats the whole patient, focusing on more than just weight. The program surrounds the patient with a team of healthcare professionals that includes physicians, registered dietitians and counselors to help people achieve and sustain long-term weight loss.


“OPTIFAST provides physician supervision to people who have a significant amount of weight to lose,” says Matt Carlen, vice president of health and wellness at Centegra Health System. “This tailored team approach provides a monitored diet and teaches people about exercise and overall wellness so they can change the behaviors that led to their weight problems.”

1) The OPTIFAST program consists of three phases. During the first phase, participants consume OPTIFAST meal replacement products instead of typical foods so they do not have to worry about counting calories. They also begin important lifestyle changes.

2) The second phase is known as the transition phase. Patients gradually learn how to add self-prepared foods back into their diet while continuing with lifestyle change education.

3) Phase three is the long-term management phase. Patients can participate in ongoing classes and support sessions to help manage their weight in the future.


OPTIFAST teaches patients accountability and provides the structure needed to develop a healthy eating plan. It emphasizes the importance of an overall wellness plan that incorporates exercise and stress management to ensure long-term success.

Centegra Health System’s OPTIFAST program provides every patient a WellBridge membership to Centegra Health Bridge Fitness Centers. OPTIFAST offers a serious solution to weight loss, improved health, renewed energy and self-esteem. To learn more about OPTIFAST, contact 877-CENTEGRA.
