But that doesn’t mean you don’t earn bragging rights for lowering that number on the scale.

Take it from Jessica Weber, a 23-year-old from Illinois, USA, who weighed 173 kilos at her heaviest, but has dropped 90 kilos in 15 months after overhauling her diet.

PEOPLE reported that Weber, a Walmart associate, has been documenting her weight loss on Instagram to help others on the same journey stay positive.

“I wanted to be open about it on Instagram because I wanted people to realise what obesity does,” Weber told the magazine.

“That they can make changes, but they’ll also face problems with loose skin in all areas. I want people to not be scared, or feel hidden of what they accomplished after weight loss.”

Weber went on to explain that she set out to lose weight after a heart-wrenching talk with her mother.

“My mum actually started crying, and told me she thought I’d die before her,” she told the website. “It just hit me hard, and I knew I had to start losing weight. It became my motivation.”

Weber transformed her body by following a low-carb, high-fat diet, but she has to remind herself daily of her mission.

“So many people don’t understand that it’s a mental battle more than physical,” she told PEOPLE.

Posting the first image of her slimmer body with excess skin also wasn’t easy, but, she told the website, her courageous move has paid off.

“I was extremely nervous. I almost didn’t share [the photo] because I thought it would get so much hate,” she told PEOPLE. “I’m glad I did because I was overwhelmed with kindness and love.”

Here she is at ages 21, 22 and 23:

In time, Weber hopes to undergo a tummy tuck to get rid of the excess skin that has resulted from her dramatic weight loss. But for now, she continues to rack up likes on her Instagram photos.

One of her most popular posts from about two weeks ago has garnered 26,500 likes and counting. In the caption, Weber declares, “I will not hate my body anymore!”
