Girl gets the best revenge by losing four stone after boyfriend cheats

Becoming recently single can really suck. But on the other hand, it's a good motivator to take a look at yourself and think about how you could be doing better in life, without the perspective of a significant other there. It's one of the best opportunities for self-growth and taking charge to get what you want. And in the process of becoming more awesome – who knows – your new vibes will probably attract the attention of more suitable matches anyway.

For Shanai Martin, she ended things with her boyfriend last year after she found out he was cheating on her. But rather than lament his betrayal and the end of their relationship, the 19-year-old used her anger to fuel something else – to lose weight and get fit. We've all heard about the "revenge body" and no matter whether you think it's right or not, Shanai managed to channel her emotions into seriously getting in shape – losing a whopping four stone (25kg) in the process.

The student from Wales went from a size 16 (US 12) to a size 10 (US 6) in a matter of nine months, and I'm pretty sure her cheating ex might be feeling a little more sorry for himself now. Shanai posted before-and-after pictures of herself on Twitter, and she looks incredible.

"9 months later and 4 stone down," she wrote as a caption to accompany the two images. "Big thanks to my cheating ex for providing the motivation for a glo up."

The post got a lot of love, with people sharing their encouragement for the 19-year-old.

She claims her new figure is not the work of a rigorous daily gym routine, but rather the gradual result of a few lifestyle changes.

She also says that her appetite disappeared because of related mental health issues, which we should stress isn't the healthiest way to go about losing weight.

But losing the weight ultimately helped with her mental health a lot, giving her more confidence and a better attitude towards life.

While her cheating ex-boyfriend might've inspired her revenge body she says that she no longer has any hard feelings towards him.

She's also dating someone different now, and she's happy to report that he treats her very well.

They say the best revenge is living well, and Shanai Martin is definitely doing exactly that.
