As it turns out, the secret to Naomi Campbell’s bangin’ figure at the age of 49 is making a point to fast on some days. But the British supermodel clarifies that she “doesn’t starve” herself.

The supermodel made the revelation during an episode on the UK iTV show Lorraine. Campbell was asked if it was true that she skips on meals for one day a week. She answered laughing that it “Could be more than one day.”

“I eat when I feel like it,” she explained. “I don’t starve myself. If I want to do a day of just not eating, I do it and just do water or juice. Depends how I feel. In the heat, sometimes I don’t [eat], I just want to do juice. It’s too hot. [It’s] never planned. It could be one day, it could be two days a week. It’s just when I feel like it.”

Back in 2010, the model told Oprah Winfrey that she has tried the Lemonade Diet “three times a year.”

“The most I’ve ever done it for is 18 days,” she said. “It’s good just to clean out your body once in a while.” Pop superstar Beyonce Knowles also famously undergone the diet back in 2006.

Campbell reveals that along with cleansing, she accompanies her diet with workouts. “I got into working out two years ago,” the model said on Lorraine. “I like it. Not so much machines. Like, circuit training. It’s not the same. I need to keep doing different things and I have a great trainer called Joe that I love working out with. I also work out here at [London gym] BXR, and kind of a community of trainers that come under Joe that…work with me around the world when I travel, so I get to keep it up. Mostly also, it’s good for your mind.”
