Hot mama alert!

Debra Messing has revealed she lost an impressive 20 pounds over the past couple of years — and it's all because of clean eating.

"About two to three years ago, I made a very, very big change the way I approach nutrition," she said in a new interview. "I think it made a big difference in how I look or at least how I'm perceived to look."

The Will & Grace icon, 45, went on to explain weight loss wasn't her goal — she just wanted to concentrate on fueling herself with healthier foods.

"I lost like 20 pounds, it wasn't my intention, that wasn't why I made the change. I made the change because I was just tired all the time," she shared. "For a long time, I just accepted that was the plight of a working, single mother. You're juggling everyday."

The bombshell admitted to growing up eating "crappy foods," and decided it was time to ax her unhealthy ways.

"I grew up on fast food and candy every day," she said. "Pizza and french fries and burgers — I love food and I've always loved food. Vegetables were not a part of my life at all"

The mother-of-one says she sees a major difference from "eating really, really clean healthy foods."

"Obviously I knew there was an association between what I ate and whether I gained 10 pounds or lost 10 pounds, but it never really became a reality for me that it shows on the outside in your hair and skin and even the clarity of your eyes. I was just stubborn."

Debra, who starts her day with a green juice, recently wrapped up filming the pilot episode for the new series The Mysteries of Laura and her new diet helped her power through the strenuous schedule.

"At least I know I'm starting my day and getting a big shot of nutrients that I need. I start out strong … For the pilot, I was shooting 15, 16, 17 hours everyday," she told ABC News. "I really depended on having that juice once or twice a day. It really gave me more energy. That made an obvious difference for me, in me feeling strong."

And it sure shows!
