rice diet

Has anyone tried the so-called 'rice diet'? I'm thinking about trying it, but it may be too much like a fad diet for me, which of course I can never really maintain. I may just eat (healthy) Korean food all the time instead because when I lived in Korea I lost 30 pounds in a year--I think because rice fills you up and you don't snack...and because I exercised as well. My husband is Korean, so it wouldn't be hard to have the food around, etc. I want to try and lose 15-20 pounds by the end of July, so I was kind of hoping to find a diet I can stick too that is healthy, but where I can see measurable success in the first two weeks too. And of course I plan to exercise as well.
