I lost 27 pounds in six months and was never hungry or craving. The eating program was easy to follow. Dr. Sheehan is absolutely outstanding; helpful, knowledgable, caring, and a shining example of what good nutrition and exercise can do for well being. The owners are always switching things up which keeps the program interesting. There are many different choices of how to do the program between shots, nutritional supplements, protein replacement, or just plain eating well and getting weekly weigh ins and counceling. I found the program flexible and affordable.
