Jacqueline Adan looks and feels great after losing a whopping 25st in just four years, but she still felt anxious about flaunting her new body in figure-hugging swimwear.
She mustered the courage to do so while on a recent holiday to Mexico – only to be sniggered at by strangers.
But the determined dieter had the best response for the cruel body shamers.
Jacqueline shared a snap of herself wearing a multi-coloured bodysuit while taking a dip in the ocean, looking happy and carefree.
Elora Harre, 23 has lost eight stone
And her photo has been liked more than 3,500 times.
Opening up in a lengthy Instagram post, she said: “When we were on vacation in Mexico a few weeks ago, it was the first time I had worn a bathing suit in a long time and it had been even longer since I wore a bathing suit without a cover up.
“I was nervous to take my cover up off and to walk into the pool or walk on the beach.
“I still felt like that same 500lbs girl… then it happened.
“A couple sitting by the pool started laughing and pointing at me and making fun of me as soon as I took my cover up off.”
So what did Jacqueline do next?
She said: “I took a deep breath, smiled and walked into the pool.
“That was a huge moment for me. I had changed. I was not the same girl anymore.
“Yes I still have a lot of loose skin, I may still feel insecure at times and yes I may still get made fun of.
“They do not know how I have worked my ass off to lose 350lbs”
“To be honest, yes it bothered me. But I was not going to let people like that affect me anymore!
“I am not going to let what other people think of me stop me from living my life. They do not know me. They do not know how I have worked my ass off to lose 350lbs.
“They do not know how I am recovering from major surgeries. They have no right to sit and point and laugh at me. That’s why I smiled.”
The Instagram star, who has 64,000 followers, refuses to let anyone tear down her major accomplishments.
She added: “It does not matter what others say or if they try to doubt you or try to bring you down. What matters is how you react to it.
“How you feel about yourself. Loving yourself just the way you are is hard. Others might not like that.
“That’s ok. I hope you love yourself. Love your body. I hope you keep doing you and just keep smiling!”
