Meet Our Fantastic Team

Dr. Claude Matar


Dr. Claude Matar founded Pasadena Weight Loss Center in 1996. He received his MD in 1986 and became board certified in naturopathic medicine and a clinical nutritionist 1998. Instead of practicing western or eastern medicine, his research into the underlying cause of illness and disease lead to the development of a completely natural and highly effective longevity protocol for men and women over 50, through patient lifestyle education. For over two decades, most clients have been reversing chronic disease, reducing or eliminating their meds and, of course, achieving optimum weight and body composition with what he then termed: the FIT50 longevity program.
