The program starts with ten weekly lessons, approximately 30 – 45 minutes in length, to teach you the core principles. Each lesson is broken up into small videos so you can watch the entire lesson in one sitting or break it up into multiple sittings when it is convenient for you. After the first ten weeks, another ten weekly personalized lessons are provided. At this point, you will have learned the core principles so lessons will focus on reinforcing those skills and helping you apply them in your everyday life. After that, you will have new lessons to choose from to help with your long-term weight maintenance.
