Jersey Shore star Vinny Guadagnino was one of the few cast mates that didn’t have an added nickname when the original series was on MTV. Mike Sorrentino had “The Situation”, Nicole Polizzi had “Snooki” and now Vinny has claimed “Keto Guido.”  He officially changed his name to on social media after crediting the popular diet for helping him lose 50 pounds.
