Twenty years ago, we decided to do something the weight-loss industry wasn’t willing to do.
Ninety-eight percent of people in our country were regaining the weight they lost within a couple of years, and today that statistic is no better.
We had to create a program that offered the best nutrition approach, but also a personal coaching relationship to help motivated people reach the finish line as their own best nutritionist.
We are proud to say that after twenty years of progress, resource development, and the best professional staff members in the world, we can bring you the best of both worlds: science and support.
