Kirstie Alley has revealed her weight loss secret after shedding some 100 pounds from her famous figure. On Wednesday, the 60-year-old took to Twitter to assure fans that no invasive or life-threatening measure were taken to sculpt her now size 6 body. Alley was previously a size 14.

NO surgery, NO flippin lasers, NO barfing, NO starving . . . Jeez . . . my products, organic food, dance. end, she wrote.

Alley is the co-creator of Organic Liaison, a weight loss program that was developed with scientists and nutritionists. The program centers around one's personal Body Game to help lose the weight.

She didn't crash diet. She wanted to lose weight the right way, but nothing was working for her, so she created Organic Liason . . . she's in an amazing place, a source told Us Weekly.

Alley, a former Jenny Craig spokesperson, has been proudly showing off her new figure in Hollywood and beyond. She strutted her stuff on the runway during New York Fashion Week, walking for designer Zang Toi in a stunning blue coat dress.

Alley also recently posed for a People Magazine photo shoot in Italy, where the actress shared what she's looking for in a partner these days.

The easiest thing on this planet is to [find sex], but I don't see the merit in that . . . what I'm looking for is someone who loves me deeply and is madly in love with me, for me, she told People.

Here is a photo tribute to the new Kirstie Alley.
