Hi Wendy and welcome to this forum.

Well done on your previous weight loss. I hope things go well this time. As you are so young, the weight may be lost easier as you will not have years of yo-yo dieting. However, beware, this is a way of life and so you must think about low carbing as a permanent change to your eating habits, otherwise, if you go back to where you were before then it will all pile back on again.

May I wish you every success.
