About Medifast

We’re Medifast, but this is about you. Without your dedication to losing weight and regaining health, we couldn’t do what we do each day. Whether you’ve come because you’re researching Medifast, or you’re here because you’re already losing weight through online ordering, shedding pounds with the help of a Medifast Weight Control Center, or gaining your Optimal Health™ with the support of an OPTAVIA Coach™, we’re glad you’re here. This blog is for you.
