Question about diets: Has anyone done (and kept doing until successful

) the Atkins Diet? Or something similar that works and not that hard?? My aunt did not do the exact Atkins but she simply stopped eating carbs. (and no sweets at all) and lost a lot of wieght. She first did it religiously for about 3 months then she still did it but every once in a while she would treat herself to some fruit, a baked potatoe, you know lil things. She has lost 85lbs in the course of 2ys. But really she lost it fast and just has kept it off. Does anyone know if that is good for you?? I heard both sides...so just wondering what works. Thanks!
