Optifast Program - Medically Monitored Weight Management Program 

Sports Nutrition 

Optifast is an evidence-based, medically-monitored weight management program that involves full or partial meal replacement with the Optifast 900 shakes. The duration of the program is generally 12 weeks long, followed by a 12-week transition period back to food. Optifast succeeds because it treats the whole you-not just your weight.  Counselling, comprehensive lifestyle education and medical monitoring are implemented with a great-tasting meal replacement to help people lose weight and significantly reduce weight-related health risks.
