Vinny Guadagnino Says His Sustained 50-Pound Weight Loss Proves Why The Keto Diet Is Different

Jersey Shore star Vinny Guadagnino is so committed to the Keto diet that he's given himself the moniker "The Keto Guido." But the New Jersey native doesn't only have a nickname to show that he's a card-carrying Keto loyalist. He also has the eye-popping abs. 

In a recent Instagram snap, the bacon enthusiast showed off his six-pack in a striking side-by-side photo. The snap showed off his bod before and after starting the low-carb, high-fat, high-protein diet. It also served as a vehicle for Vinny's statement about the overall effectiveness of the Keto diet... and the longevity of his six-pack.

Here's what he wrote: "The question of 'how long of time in between these pictures' is not the important question to ask here in terms of 'how long did it take to get from left to right'... I’ve always been able to get from left to right in a matter of months by committing to almost ANY diet and workout plan. But after being done with those miserable diets and workout plans I would always go back from right to left... so the question of 'how long of time between these pictures' IS important for the reason of 'how long I’ve been able to STAY the guy on the right '. The answer to that question is about 4-5 years now."

In short, these abs are here to stay, people!
