Hello and welcome,
The atkins diet is great and so is this site. They have all kinds of ideas. I need to lose about 20 lbs too. You have to remember you did not gain the weight over night and will not lose it over night too. A good diet and exercise should work great. If you follow the atkins plan you should do great, just be sure to eat the veggis and drink lots of water.
Do you have the Atkins book? If now I would get it. It if full of great things. They sell them at Wal Mart.
I am sure if you list your questions that someone here will answer them.
Good luck.
