My girlfriend dumped me — I got revenge by losing 141 pounds on my own

He lost a girlfriend — and 141 pounds as a result.

Nithun Puvirajasingam, 27, gained 97 pounds during the COVID-19 lockdowns, going from 220 to 317.

He claims his girlfriend couldn’t bear to see him “eat himself to death” and left him — that’s when he decided to get his life back on track.

Now, he weighs 176 pounds and works as a personal trainer in London.

“It’s been three years of consistency for me now. I haven’t taken more than a week off,” Puvirajasingam declared to SWNS. “I feel great, and I can’t ever imagine going back to that lifestyle.”

Puvirajasingam says he used to be very sporty and loved to exercise.

He played rugby and went to the gym often — until the pandemic hit, leaving him and everyone else stuck at home.

“The weight started piling on. I didn’t see any friends or family — just stayed in with her and pretty much ate and smoked,” Puvirajasingam said about his now ex-girlfriend.

Puvirajasingam said the woman, whom he did not identify, didn’t want to watch him destroy himself.

“She pretty much couldn’t watch me eat myself to death, which is understandable,” Puvirajasingam explained. “She said if I didn’t change she’d leave — and I didn’t change.”

Puvirajasingam said he had very dark thoughts, constantly wore an oversized jacket to hide his weight gain, and avoided seeing friends in the aftermath.

After two weeks of despair, he decided he needed to turn his life around.

Starting in February 2021, he slowly fixed his diet, quit smoking, and began to exercise.

“I bought resistance bands, a bench, dumbbells, a barbell, put some mirrors up, put down some rubber flooring, got myself a boxing bag, and slowly started getting back into my routine,” Puvirajasingam shared, noting that he posted progress pictures to social media to motivate himself.

Three years later, he’s built a body straight out of Hollywood and acquired his personal training license.

“I don’t even recognize that man anymore,” Puvirajasingam said as he reflected on his breakup. “I was grateful in a way because it gave me that push I needed to get out of my comfort zone and prove everyone wrong.”

A person who weighs 155 pounds can burn up to 800 calories in an hourlong boxing class, Women’s Health UK reports.

Besides boxing, other people have recently found weight-loss success by practicing taekwondo, walking 10,000 steps a day, and jumping rope.
