There was a reason behind Jennifer Lopez‘s recent diet challenge.

The actress, 49, who cut out carbs and sugar for 10 days along with boyfriend Alex Rodriguez, said the idea for the extreme diet came from her trainer while prepping for a movie where she’ll have a tiny wardrobe.

“I’m getting ready for this movie called ‘Hustlers’ and I have to play a stripper so I’m getting ready for that,” she said on “The Ellen Show” on Wednesday. “I work out a lot, I try to stay healthy but [my trainer] was like ‘let’s do something to move the needle.’”

But when presented with the idea to eliminate bread and sweets the “Shades of Blue” actress wasn’t sure she was up to it.

“That’s most of my diet,” she admitted. “I was like ‘Completely? Like cold turkey?’”

However the couple successfully completed the challenge on Jan. 31, but it didn’t come without its struggles.

“You feel like you’re in an alternate reality or universe, like you’re addicted and you think about it all the time,” she said of bread-themed daydreams, but admitted that by the time the 10 days were up her cravings weren’t too bad.

“When you go back to the sugar you don’t want it as much, it’s something you get used to a little bit,” she said. “It takes down the inflammation and you feel smaller and less swollen than you get addicted to that feeling too.”
