About Dr. Leichtberg

Dr. Josh Leichtberg is a world-renowned internist, researcher and author. He specializes in Internal Medicine, with special focus on clinical nutrition, metabolism and obesity, and has over twenty years' experience helping patients deal with these and many other difficult health issues.

Dr. Leichtberg began his innovative work in nutritional and metabolism research as director of a medical group in Calabasas and Beverly Hills, California. It was there, through his work with hundreds of overweight individuals, that he pioneered a breakthrough in natural weight reduction, creating the BioSlim System. Eventually – recognizing that most weight loss programs today attempt to trick the body into losing weight instead of normalizing and optimizing the body's metabolism naturally – Dr. Leichtberg decided to make his new, natural system available to the general public. Since then, millions of people around the world have discovered BioSlim, and been astounded by the ease with which real permanent weight loss can be achieved, naturally and healthfully.

Once his successful track record with the BioSlim System was established, Dr. Leichtberg turned his attention to a growing problem in our society: childhood obesity. A father himself, Dr. Leichtberg wanted to give parents the tools they need to combat this growing, severe health problem in kids. He worked tirelessly to design a system that is nutritionally appropriate to the needs of growing children, helps them shed unhealthy excess weight, and would be acceptable to kids. The breakthrough BioSlim Youth System is the result of that work.

Dr. Leichtberg continues his work today, striving to help people achieve better health and fulfill their weight loss goals.
