Khloé Kardashian is helping people get revenge — in the healthiest way possible!

In a new trailer released Wednesday, the Revenge Body host asks multiple people on her upcoming new E! show, “Who do you want to get revenge on?” to which they reply, “my ex-fiancé,” “my dad” and “the person that hurt me.”

“Growing up, people called me the fat sister until one day, I started working out, eating right, and putting myself first,” Kardashian, 32, says in the new promo, which teases a special preview of the show Wednesday night at 9 p.m. ET on E!

“Now, I’m helping others transform and shut down the shamers,” she continues.

Keeping Up with the Kardashians matriarch Kris Jenner is also excited to preview the show. “Can’t wait to watch!!!!” Jenner, 61, tweeted.

On Revenge Body with Khloé Kardashian, the reality star will work with experts to help people faced with various challenges – from being dumped to losing their jobs – by giving them total body makeovers, PEOPLE previously reported.

“Looking great is always the best revenge,” Kardashian said in a statement. “It’s so exciting to be able to mentor these people through their full-body makeovers and I can’t wait to see the incredible results at their final reveals!”

Revenge Body premieres Thursday, Jan. 12 on E!
