A slimmed down Alec Baldwin made a high spirited appearance at this weekend's Screen Actors Guild Awards.
And during the ceremony he revealed the secret behind the newfound spring in his step.
The 30 Rock star told reporters that after finding out that he was prediabetic he decided to take action before it got worse.
He discovered his condition in May 2011, and since then has lost 30 pounds in weight.
A prediabetic condition means that the sufferer is likely to become a type 2 diabetic in the future if no action is taken.
Alec walked away from the ceremony with the award for Best Actor in a TV Comedy for his role in 30 Rock.
