Map of italy tiber river for We want to go on a diet. This means, horrible as it sounds, we will have to eat less cake, ice cream and chocolate, and more rabbit food such as lettuce, tomato and carrots.

If virtually all of us go on this diet, it will be difficult to do unless farmers, grocers, restaurants, change what they offer for sale, in order to accommodate us.
