There's nothing worse than losing a bunch of weight, becoming a national spokesperson for Jenny Craig, then gaining it all back and more -- all in front of the public eye.
That's exactly what happened to Kirsite Alley, the "Cheers" star who launched her comeback over her weight travails.
In April, Alley returned to the "Oprah Winfrey Show," where she had once famously paraded in a bikini after losing 70 pounds, and lamented falling "off the wagon."
"She was very candid about hating her body," said Kinzel. "It was upsetting, but at the same time, incredibly relatable."
Alley, who slimmed down to 145 pounds while on Jenny Craig, blew up to 228 pounds after her three-year contract ended. She admitted to People magazine that butter was her downfall.
"A lot of butter. If I'm at the movies, usually I eat popcorn without butter, but I'd say, 'I'm at the movies, so who cares?'" she told People in May. "And toast with butter. Or let's say I had two cups of pasta and six tablespoons of butter on it. There was a lot of butter going on."
When he caught the eye of his ex-wife, Britney Spears, Federline worked it out as the resident hunk of her backup dance crew. Now, his former six-pack abs have gone to flab, and the 31-year-old father of four can barely handle 18 holes of golf, let alone a sweaty stage routine.
Federline's excuse for looking nine months pregnant? "It's daddy weight!" according to Shar Jackson, the woman he was engaged to before Britney, and with whom he has two children.
"When you are a full-time parent, sometimes you can't focus on you," she told Us magazine.
Apparently, Jackson was on to something. According to a recent report by a British research firm, the average weight gain during pregnancy was 14 pounds -- and that was by the fathers-to-be.
Phoenix's weight gain coincided with his exit from Hollywood. When the "Walk the Line" actor announced that he was ditching acting for a career in music, it appeared he had just let himself go.
When the bearded, bloated Phoenix turned up at a party last December, some Hollywood watchers were actually questioning his sanity.
Kinzel said the public has a very different reaction when male celebrities gain weight.
"With women, it's almost more offensive when they dare not force themselves to fit that idealized beauty," she said. "But with men who go down that same path, we look at them as kind of sad, probably just depressed. 'Joaquin is having a bad year.'"
Fans online can't stop speculating whether Clarkson is pregnant, especially following her spring appearances on "Saturday Night Live" and "American Idol."
Her reps keep squashing the rumors, but it's clear Clarkson continues to climb the scale. Comments like this one on the Web can't help: "She's gotten huge! I just saw her on 'SNL.' Lay off the Twinkies, or you're going to have a lot of new material about guys breaking up with you."
In the September issue of Self, she shot back at her critics. "When people talk about my weight, I'm like, 'You seem to have a problem with it; I don't. I'm fine!'" Clarkson told the magazine.
"My happy weight changes," said Clarkson, the "Idol" alum. "Sometimes I eat more; sometimes I play more."
She said she works out to feel better, not necessarily to lose weight. Her secret to losing weight, she said, is to not go on a diet.
