Alec Baldwin's svelte new look that I wrote about last week wasn't just the result of some healthy living epiphany — turns out the guy had a serious incentive: beating diabetes. 


The 53-year-old, who won his 6th SAG Award last night for Best Actor in a Television Comedy, revealed to Entertainment Tonight during the ceremony that he was diagnosed as prediabetic in May 2011. As a result, he immediately changed his diet in a bid to avoid the disease and correct his health. 


"I gave up sugar," he told Access Hollywood earlier this month. "I lost 30 pounds in four months. It's amazing."


"(I do) Pilates, spin, not as much yoga as I'd like," he added. "When we're shooting ['30 Rock'] it's tough ... When we're shooting and I can't work out, I just have to eat less. So, I'm very conscious of that. But sugar was the real killer for me — that was the problem."


Diabetes has been making headlines in the news lately thanks to celebrity chef Paul Deen's not-so-surprising reveal that she had been secretly battling the disease for three years. The Food Network host, known for her high-fat Southern cooking, joins a growing list of Hollywood stars diagnosed with with Type 1 or Type 2 diabetes — including Nick Jonas, Tommy Lee and Halle Berry. 


The CDC estimates that around 26 million Americans have a form of the disease, primarily Type 2, while a whopping 79 million adults in the U.S. are living with prediabetes.


The most common strategy for those looking to avoid injecting themselves with insulin for the rest of their lives is to increase exercise and eat better — something these 10 celebrities did in 2011 with great success
