I think I have been on every diet that has ever been created in the past several years...
I am serious...Atkins, South Beach, Low Carb, High Carb, Ceral Diet, Cabbage Diet, Fasting. Cleansing, Pills...you name it, I have tried it. I tried them all in the hopes of quick weight loss. Did I lose weight on some of them? Oh yeah. Some I have even lost my hair, my nails got disgusting, and some pills made my heart race. Some days I was miserable because I deprived myself of sugar, carbs, and everything else I wasn't allowed to eat or drink on that given diet.
Recently I came to the conclusion that enough is enough. I am watching what I eat and getting my rear moving. No more dieting. Will it be a slow way to lose weight? Probably. But I am sure I will be healthier, happier and lighter later on. That's OK with me.
Really, I think all diets can work in the short-term and give you quick weight loss--if you stick to them. For long term weight loss though, I don't know. I only say that because I have never lost weight quickly and kept it off long-term. Maybe someone else can chime in who has, but I don't know anyone who has.
