Sophia, do you by any chance have the opportunity to work w/ a nutritionist with your dr.'s office or school? It would be really helpful for you to learn and be guided by someone regularly (and in person) to help you stay accountable.
14 is young. And kinda hard to do this all alone. But it is do-able. I highly recommend you consider combining the 'principals' of the carb addicts diet w/ just general healthy nutritional advice, and never go below 1400 calories a day!
Would rather see you begin to find areas of activity that interest you, than to see you cut your calories. That's a recipe for lifelong disaster with your metabolism!
Let us know how we can support you!!! Go Sophia!
Live, Love, Laugh ...make each day memorable and enjoy the journey.
