*Shonda Rhimes has lost more than 100 lbs., and while the creator of such hit shows “Grey’s Anatomy” and “Scandal” is celebrating the amazing feat, the turning point came when she got on a plane, sat in her First Class seat and couldn’t fit.

Rhimes shares that enlightening moment in her upcoming book, “Year of Yes: How to Dance It Out, Stand In the Sun and Be Your Own Person.” In an excerpt, she wrote:

“In 2014 I get on a plane to New York. I’m a fancy TV writer. So I have a big first-class comfy seat. I grab the seatbelt and – well it’s gotta be broken. Right? RIGHT? I do not have a broken seat belt. I am literally too fat for a first-class airplane seat belt. I have been saying yes to being fat.”

The Golden Globe winner continued:

“I’m not cutely chubby. Or nicely plus size. I am massive. Look, I believe everyone has a right to love their body in whatever size and shape it comes in. But I don’t FEEL good.”

Rather than feel sorry for herself and emotionally eat her way to an even bigger size, Rhimes decided to get her weight under control, and it’s been one of the best decisions of her life so far.

“[Now] when I walk past the mirror I think, “Who is that?” The girl in the mirror is a size she hasn’t been since she was 16 years old. But it’s me. That girl looks happy. All it took was the right kind of yes.”

Shonda credits her weight lost to moderate exercising and smaller portions, and she tells the current issues of PEOPLE that she doesn’t really have a particular end goal in sight.

“For me, it’s never truly been about a number,” says the creator of Grey’s Anatomy and Scandal, who is featured in the current issue of PEOPLE. “It’s just about feeling good. I feel good and really healthy.”
