Did you get a physical done before you started losing weight? That way you can see if there are any medical exceptions...such as Thyroid disease. That help you keep those pounds on. If its not all that. It could just be that they diet you are trying, just isn't right, so if it doesn't work this time, maybe try another type! Either way, good luck, and remember, even if you aren't losing the weight, you are getting healthier!!! YAY to living longer!!!
