Kristin Davis "wasn't eating any real food" at the height of her Sex and the City success.

The 61-year-old actress played Charlotte York in Sex and the City, the hit HBO show, and Kristin admits that she became very self-conscious about her appearance as the series grew in popularity.

Speaking on her Are You a Charlotte? podcast, Kristin explained: "There was a time earlier in the show where you can see my ribs -- like I had dieted. It was like later in the season, and it was one of those hot summers, and I just remember I just ate MandMs.

"I just ate MandMs like for a couple weeks. I don't know why I didn't lose my mind or whatever, and like I have no breasts left, like it's just like bones.

"What I mean is that I wasn't eating any real food."

Kristin kept her weight down by following the lead of some ballet dancers.

She said: "It wasn't healthy. And I did go to this acupuncturist one time. He was like, 'Don't put that in your mouth.' And I was like, 'Why not? It's all I eat.' Because I had read that ballet dancers smoke cigarettes and eat candy bars. So I was like, 'Well, if they can do it, I can do it.' But I wasn't smoking a cigarette."

Meanwhile, Kristin previously admitted that she was unimpressed by the Sex and the City pilot.

The actress never imagined that the TV show would become so successful.

Kristin said on the Are You A Charlotte? podcast: "I was never a fan of the pilot. It didn't seem smooth. It seemed kind of choppy and hectic.

"But I also feel my personal theory on pilots in general is that if they're too good - if the pilot is too formed - the show might not be good."

Kristin also revealed that she was initially offered $5,000 to play a "recurring character" on the show.

She shared: "One day, I'm in my trailer and she [a producer] knocks on my door and I opened it and she says, 'Oh, well, we have this paperwork we need you to fill out.'

"And I was like, 'OK.' I take the paperwork and I look at it and it seems to be a new contract, but it's only two pages long, and I'm like, 'What is this?' And it says, 'You will be a recurring character and you will be paid $5,000.'"
