You need to get off the diet rollercoaster! I think that you need to start looking at this as a way of life rather than a temporary fix. That will be a big step in getting you off the rollercoaster. You may want to try the maintenance phase of Atkins for a while in order to steady and stabilize your weight. It will also help you to see what you will be eating for life and how much of it you need to eat in order to maintain your weight. Do that for a couple of months and then maybe try going back to Induction and working your way back to maintenance. Remember that you will need to adjust your final carb level to reflect your new lower weight when you return to the maintenance phase. It may be a bit of an unorthodox approach but it may have a real impact on your body and help you understand what living the low carb life will be like for you. If you can master that then you will not keep gaining the same 15 pounds again and again and again. Hang in there, you CAN do it.
