HOLLYWOOD, Calif. – Would you scale back eating if it would change what you see on your scale?

For more than a decade, Greg Gilman made a living interviewing some of Hollywood’s biggest stars. Then, in August, he decided to become one.

“When I was doing entertainment journalism I felt like I wasn’t really contributing anything very meaningful to this world. But when I’m singing on stage and writing songs I know I am,” Gilman said.

These days the only thing he writes are his own songs, which he performs every week at a popular songwriter’s showcase called “The Writer’s Room" at “The North End of Hollywood,” and it’s all thanks to a new diet craze called “Intermittent Fasting.”

Gilman lost 30 lbs in three months, which came with an unexpected perk: the return of his six-pack abs.

“These took a 10 year hiatus,” he joked. “It’s pretty cool to look in the mirror and feel good about yourself.”

But the real benefit has been a boost in confidence on stage, which Gilman said helped him take that final step towards full-time musician.

“The more confidence you have in your physical appearance and also what’s going on inside, the better performer you’re going to be,” Gilman said.

The idea behind Intermittent Fasting is simple: worry less about what you eat and more about when you eat it.

There are many variations. But the most popular one is often referred to as “16-8,” eating during an eight hour window and then fasting for 16 hours.

“There are many benefits associated with that, but the most important is that your body gets a chance to burn your stored fat. When we graze all day long we never burn fat,” said nutritionist Juli Keene.

But while results can be dramatic. Some experts warn this diet isn’t for everyone.

“You really do lose your hunger and you get more satiety,” Keene said. “A lot of people who might have been on the fence with like an eating disorder can get too thin.”

But Gilman says the diet has allowed him to finally shed those stubborn extra pounds that no amount of working out could do. Now, he says he is ready for life on the intermittent fast lane, skipping meals to add a skip in his step.

“First bite in what is it? 26? It’s 9:39 now, so I ate yesterday at 6 p.m. so what is that? I’m terrible in math, that’s like 27 hours,” said Gilman.
