Stavros Mastrogiannis is a sustainable weight loss coach.  He is the owner of Live Your Way Thin LLC,  a personal training facility in Danbury, CT and the creator of the Live Your Way Thin System.  A unique system created specifically for sustainable weight loss.  He is also an author of four books on the subject of weight loss.  He has been working in the weight loss field for over 25 years.  He lived in Greece before moving to the United States in 1987, where he was immersed in a culture that embraced a healthy lifestyle. After moving to the U.S., he continued to visit Greece every year. Over time, he observed changes in eating habits, exercise and daily living, resulting in a weight problem similar to that in the U.S. 
Early in his fitness career it became very obvious to him that with most diets and weight loss programs people regained the weight back, so he dedicated his fitness career to finding the answer to sustainable weight loss.  That dedication has paid off because today he has become the authority in sustainable weight loss and you will be hard-pressed to find anyone who knows more about the subject than he does.
