Counting Carbs & Calories

My sister, Dena, might have something here. She is counting her carbohydrates and has lost ten pounds already in like two weeks. I'm doing the workout thing and I am at a plateau. Stuck...I losing inches though. Maybe if I incorporate what she is doing into my world I might can reach my destination of 155 a lot quicker. I still want something that is realistic and not temporary. Basically, whatever I change I want it to be a life change not something that is for the moment. Diets...no carbohydrates,,,only juicing...whatever else is out there gets you where you want to be...but when you start back your normal lifestyle you gain that and more. Conflicting. I don't like to count...call me lazy...but I do know that I need to do something because I am stuck at a plateau.
