Well, that's one way to do it.

A slimmed-down Kimora Lee Simmons revealed how she recently lost 25 pounds.

"I shed the fat by not eating," the designer, 35, told PopEater's Rob Shuter. "But I don't like to tell the kids that so they think they shouldn't eat."

The mother of three (two daughters with ex-husband Russell Simmons, and a son with current hubby Djimon Hounsu) went on to slightly amend her comments on her seemingly draconian diet.

"I watch my portions, and I eat leaner proteins and vegetables and stuff like that," she said, noting some days she'll limit caloric intake to fruit, smoothies, or protein bars.

The Missouri native revealed that moving to L.A. was the reason for the slim-down.

"I was out one night with two famous sisters," -- Simmons told Shuter she didn't want to say who -- "when a bunch of burgers were being passed around. I went to grab one and the two of them looked shocked. They said 'we don't eat.' Then after I grabbed a burger they said they were joking, but I knew they weren't!"
