Hello, would you please give us an example of what you eat each day ? You know I hate to say it, you probably don't want to hear it, but I'm a MOM so I'm going to say it!!
Your Goal weight may be a little under for your height and you say you've been low carb'n for 3 years ?? My goodness girl, you body is still developing, You need more good carbs in your diet. Why do you feel you have to lose so much weight ? If you have been eating these bars instead of real food, sorry girl, it is not healthy, at any age.
There is tons of recipes in the recipe threads and read other peoples Journals to see what they are eating.

Waiting to hear from you
Kathy
