What is a good, Inexpensive diet plan?

There is a sushi diet. You can buy the seaweed packs at a health food store and make the sushi your self. You can add in some smoke salmon too. Buying sushi would be expensive but making it your self is really cheap and it can full you up pretty fast. I went on a seaweed and rice diet and it help me loose 5 pounds in a week but I also walked alot and a couple of weights.
