Kirstie Alley starving herself?

Kirstie Alley is putting her health in danger with her dancing diet.

The Dancing With the Stars contestant is desperate to get her weight down to 130 so she can slip into a size 4 dress, so has been starving herself and exercising to the point of exhaustion.

“Kirstie is burning the candle at both ends and came close to blacking out during rehearsals,” an insider told the National Enquirer.

“She frequently eats one small meal before going in for seven hour dance practices and she’s getting by on as little as four hours of sleep a night.”

Sports medicine expert Dr.Gabe Mirkin estimates that Kirstie, who says she averages a 1,400-a-day calorie intake, is burning up to 2,800 calories a day by intensive dancing and risks serious health problems with a starvation diet.

“If Kirstie continues,she may suffer from electrolyte deficiency,particularly sodium depletion,which can lead to heart arrhythmia and sudden death,” he added.

“The fact that she’s falling demonstrates that she’s doing serious damage to her body.”
