Kirstie Alley Drops 17 Pounds In Two Months On Wacky New ‘Gone For Good’ Diet

Desperate-to-downsize Kirstie Alley is shedding weight on a wacky upside-down diet!

The “Fat Actress” star, 67, has already dropped 17 pounds in two months by surviving on just 1,200 calories a day and having dinner for breakfast — and breakfast for dinner.

“Kirstie calls it her ‘Gone for Good’ diet!” a source told RadarOnline.com.

“She’ll have a half roast chicken with roasted carrots or salmon with steamed broccoli for ‘breakfast.’ Then, around five o’clock, she’ll eat ‘dinner’ — oatmeal with almond milk and a little fruit to sweeten it,” revealed the source.

The former Cheers star, who has had massive weight swings of more than 150 pounds over the last 15 years, crushed the scales at a whopping 244 pounds on England’s version of Big Brother this summer.

“Kirstie was humiliated by how big she looked on the show and was desperate to find a solution. This whet her appetite nicely,” an insider said.

But experts warned Alley’s constant yo-yoing may eventually kill her.

“Rapid weight loss causes tremendous loss of muscle with the fat that is not restored,” said Dr. Gabe Mirkin, who has not treated Alley. “Loss of muscle includes loss of heart muscle, which sets you up for heart failure and irregular heartbeats that may be fatal.”
