Need Advice

I have a friend getting married in less than a month. She is really worried about her upcoming wedding and still being able to fit into her dress. She said that she really thinks that she has gained a few pounds since she had her dress fitted and she was wondering if I knew of any crash diets that work. She wanted to know if I have come across anything on the internet that promises weight loss in a hurry. I have to say I have some across many sites that promise weight loss since I started blogging. I have never really tried any of them for myself so I am not sure if she will get the results that she is seeking. I am sure she is just over stressed and will still look beautiful in her wedding dress.
I really can't wait for her wedding because weddings are one of my favorite things to see. I really love seeing a new couple get married and promise to be together forever. they are just so fun. The party afterwards is not to shabby either.
