De, welcome to 3FC!
The best diet in the whole world is....the one YOU can stick to! Really! It's different for every person. Do your research, check out the forums for the type of eating plan you think you'd like, try out that style of eating at home, to see if you can live that way, because you need something you can stick to for the long term, not just during your weight loss...you need a plan for after the "after" pics, too, don't forget.
Best of luck to you, De! Hope to see you around the forums. Just jump in and start posting!
