Raw Food Diet.. what are the benefits of this lifestyle?

I recently saw some information on the internet about a raw food diet, but only know some of the information... If there is anyone on this diet could you tell me what you have noticed being on it? Some people say it can change your eye color... is that true? And how much weight can I expect to lose in about 30 days if I weigh 150 and am 5.2 female going on this diet.
