Kirstie Alley's death at 71 shocked her friends and family, given that she struggled with colon cancer for a short while before she passed.

Tributes from co-stars and friends have flooded social media, as fans remember her for her various roles.

But what many remember her for, is her wildly fluctuating weight and how she treated weight loss as an athlete, and how she always remained upfront about the same.

Alley's weight ballooned around her '50s, with what she called "men's problems" and the media latched onto it, in not-so-many pleasant ways.

She later spoke about her weight with and on “Oprah” where she admitted that media pictures showed her how fat she’d become.

She embarked on a weight loss journey with Jenny Craig and stunned everyone by appearing in a bikini on “Oprah”, in 2006, showing off a curvy but slimmer figure.

Later, she launched her own weight loss program, penned a book about her struggles, and even appeared on the sitcom, “Fat Actress.”

She remained open about her weight issues all her life, and for many, remained a body-positive hero.

Fans remember her for her roles, her comic timing, and her honesty about her weight.
