Ricki Lake reveals how she lost over 30 pounds, poses in dress from 2007 premiere

Ricki Lake is celebrating her weight loss by partying like it's 2007.

The former talk show host, 55, posed in the same dress she wore 17 years ago to the premiere of the movie "The Business of Being Born" in a picture she shared Wednesday on Instagram. "Oh, this old thing??" she wrote in the caption. "Just had it hanging around."

Lake added, "Originally wore this dress to the 'Business of Being Born' world premiere in 2007 and now here I am wearing it again in 2024!"

In the comments, fans applauded Lake for her weight loss, which she also opened up about in an interview with "Good Morning America" that aired Thursday. The "Hairspray" star revealed she has lost 35 pounds since October through exercise, the keto diet and intermittent fasting.

But Lake denied using medication to help her lose weight, even though she says a doctor suggested she do so. "He was saying (I wasn't) going to be successful without it, is what he said to me," the actress said on "GMA." "And I like a challenge. I like proving people wrong. It pissed me off.

"I think it's safe to say I'm in the best shape of my life," she went on to say, adding, "This is what happy looks like. I could cry. I'm so happy."

Lake previously revealed in February that she had lost weight after making a "commitment to myself to get healthier." At the time, she also shared that she was initially worried her "body would not drop the lbs like it had in the past" at age 55. "This is the healthiest way I've lost weight in all of my years," she wrote.

Lake's husband, Ross Burningham, also joined her in the weight loss effort. "I have this new marriage, and I'm so blissfully happy with this amazing man, my perfect man," she said on "GMA." "If I pinpoint one thing that was not working in our lives, (it's) that we were carrying this extra weight."

In recent months, Lake has shared similar photos showing herself posing in old outfits, including one in February where she slipped into a swimsuit she wore on the cover of Us Weekly in 2007. "I held onto this #NormaKamali one-piece for all these years wondering if I would ever be able to wear it again," she wrote.
